Mit Kapazitätszusage: mindestens 70 % der Nennenergie bis zu einem Energiedurchsatz des 8.000-Fachen der Nennenergie je Batterieeinheit (entspricht 10.000 Ladezyklen bei 80 % Entladetiefe). Garantiebedingungen: www.sunenergyxt.com/garantie
Abweichend hiervon beträgt die Garantiedauer fünf (5) Jahre, wenn das Produkt im Freien in einer Entfernung von weniger als 5 km (Luftlinie) zur Meeresküste aufgestellt ist oder war.
Herstellerangaben für die oben genannten Geräte. Die Garantie gilt nicht für weitere Bestandteile eines Sets.
Erweiterbar ausschließlich mit dem SunEnergyXT B500, kompatibel mit 500, 500 PRO und 500 PRO AC Core; höchstens 5 Erweiterungsspeicher je Kopfspeicher. Speicher anderer Hersteller werden nicht erkannt.
Der B500 ist ein Erweiterungsspeicher ohne eigenen Wechselrichter, ohne PV-Eingänge und ohne AC-Anschlüsse. Er funktioniert nur zusammen mit einem SunEnergyXT 500, 500 PRO oder 500 PRO AC Core Kopfspeicher.
Zusätzliche Versorgungsstrategien in der SunEnergyXT App erfordern ein Energiemessgerät aus der Kompatibilitätsliste: www.sunenergyxt.com/komponenten. Andere Messgeräte lassen sich gegebenenfalls über kompatible Smart-Home-Systeme einbinden und die Steuerung erfolgt dann lokal und nicht über die App.
Für die Garantie ist keine Internetverbindung erforderlich. Softwareaktualisierungen, Ferndiagnose und App-Funktionen setzen eine Internetverbindung voraus.
Integrierte Heizfunktion: Bei Zelltemperaturen unter 0 °C werden die Batteriezellen automatisch vorgewärmt. Bis zum Erreichen der Betriebstemperatur stehen Lade- und Entladeleistung nur eingeschränkt zur Verfügung; Dauer und Ausmaß hängen unter anderem von Umgebungstemperatur, PV-Leistung und Zahl der Speicher ab. Oberhalb von 45 °C wird die Leistung reduziert.
Für jedes Gerät werden Softwareaktualisierungen, die zum Erhalt der Sicherheit und der in der Bedienungsanleitung beschriebenen Funktionen erforderlich sind, mindestens für die reguläre Dauer der jeweiligen Herstellergarantie bereitgestellt: fünf Jahre für BK215, BK215 PLUS, B215 und B215 PLUS, zehn Jahre für 500, 500 PRO, 500 PRO AC Core und B500. Für den EV3600 werden Softwareaktualisierungen abweichend von seiner zweijährigen Garantiedauer mindestens fünf Jahre bereitgestellt. Diese Zeiträume gelten auch, wenn sich die Garantiedauer wegen einer Aufstellung in Küstennähe nach Artikel 3.1 der jeweiligen Garantieerklärung verkürzt. Beginn und Nachweis des Zeitraums richten sich nach Artikel 3 der jeweiligen Garantieerklärung; bei Weiterverkauf geht der verbleibende Zeitraum auf den Erwerber über.
Der Hersteller kann die Bereitstellung verlängern; eine Verkürzung des einmal angegebenen Zeitraums erfolgt nicht. Vor Erreichen des Endes werden die Nutzer informiert.
Diese Angabe lässt die gesetzlichen Gewährleistungsrechte des Verbrauchers gegenüber seinem Verkäufer, einschließlich der Aktualisierungspflicht bei Waren mit digitalen Elementen, unberührt.
Der Hersteller stellt für die genannten Produkte Softwareaktualisierungen einschließlich Sicherheitsaktualisierungen bereit. Die Auslieferung erfolgt über die Netzwerkverbindung des Geräts; eine bestehende Netzwerkverbindung ist hierfür Voraussetzung. Beim EV3600 und bei Erweiterungsspeichern erfolgt sie über den Kopfspeicher.
Über Softwareaktualisierungen, die den Funktionsumfang oder die Zusammenarbeit mit gelisteten Komponenten verändern, informiert der Hersteller die Nutzer vorab per E-Mail, in der Regel mindestens einen Monat vor Wirksamwerden. Sicherheitsaktualisierungen, die keinen Aufschub zulassen, können kurzfristig bereitgestellt werden; die Nutzer werden dann spätestens mit der Bereitstellung informiert.
Die Garantiedauer beträgt für alle in Artikel 1.2 genannten Modelle einheitlich zehn (10) Jahre. Sie beginnt mit dem Kaufdatum (Datum der Rechnung des Erstkaufs). Die Garantie ist an das Produkt gebunden und geht bei einem Weiterverkauf innerhalb der Garantiedauer auf den Erwerber über. Für einen nachträglich erworbenen Erweiterungsspeicher B500 läuft die Garantiedauer gesondert ab dessen Kaufdatum. Abweichend hiervon beträgt die Garantiedauer fünf (5) Jahre, wenn das Produkt im Freien in einer Entfernung von weniger als 5 km (Luftlinie) zur Meeresküste aufgestellt ist oder war. Grund ist die erhöhte Korrosionsbelastung durch salzhaltige Luft.
Im Freien aufgestellt ist ein Produkt, das nicht in einem geschlossenen Raum steht, etwa auf einem Balkon, einer Terrasse, einem Dach oder im Garten. Dass das Produkt in diesem Bereich aufgestellt ist oder war, hat der Garantiegeber nachzuweisen.
Ergänzend garantiert der Garantiegeber, dass die nutzbare Speicherkapazität des Produkts während der gesamten Garantiedauer nicht unter 70 % der Nennenergie von 5.024 Wh je Batterieeinheit sinkt. Die Kapazitätszusage gilt, bis der kumulierte Energiedurchsatz der Batterieeinheit das 8.000-fache ihrer Nennenergie erreicht hat; das entspricht 10.000 Ladezyklen bei einer Entladetiefe von 80 %, den Referenzbedingungen der im Datenblatt angegebenen Zyklenlebensdauer. Maßgeblich ist der vom Batteriemanagement erfasste Energiedurchsatz, den der Garantiegeber Ihnen auf Anfrage mitteilt. Bei einem Verbund aus Kopfspeicher und Erweiterungsspeichern gilt die Kapazitätszusage für jede Batterieeinheit gesondert.
Nutzbare Speicherkapazität ist die Energiemenge, die der vollständig geladenen Batterieeinheit über den gesamten vom Batteriemanagement freigegebenen Ladezustandsbereich bis zur Abschaltung durch das Batteriemanagement entnommen werden kann; nutzerseitig eingestellte Ladegrenzen bleiben außer Betracht. Sie wird an den Batterieklemmen (gleichstromseitig) oder anhand der vom Batteriemanagement bilanzierten Entladeenergie ermittelt, bei einer Zelltemperatur von 25 °C ± 2 °C und einer konstanten Entladeleistung von 0,2 C (rund 1.000 W je Batterieeinheit). Die Messung führt der Garantiegeber oder ein von ihm autorisierter Servicebetrieb unentgeltlich durch; Sie erhalten ein Messprotokoll. Der vom Batteriemanagement ausgewiesene Kapazitätswert dient der Vorprüfung und ersetzt die Messung nicht.
Die Kapazitätszusage endet mit dem Ablauf der Garantiedauer oder mit Erreichen des vorgenannten Energiedurchsatzes, je nachdem, welches Ereignis früher eintritt. Die Garantiedauer nach Artikel 3 und die Zusage nach Artikel 2.1 bleiben von der Durchsatzgrenze unberührt.
Diese Garantie gilt für Produkte, die in einem der folgenden Staaten erworben und dort betrieben werden: Deutschland, Belgien, Italien, Luxemburg, Niederlande, Österreich, Portugal, Spanien, Frankreich, Griechenland, Rumänien. Wird ein Produkt in einem dieser Staaten erworben und in einem anderen der genannten Staaten betrieben, bleibt die Garantie bestehen.
Diese Herstellergarantie ist freiwillig. Sie tritt neben Ihre gesetzlichen Rechte bei Mängeln und schränkt diese weder ein noch ersetzt sie diese. Ihnen steht gegenüber dem Verkäufer eine gesetzliche Gewährleistung von mindestens zwei Jahren zu. Die Inanspruchnahme dieser gesetzlichen Rechte ist für Sie unentgeltlich.

Product details and scope of delivery
SunEnergyXT AC CORE
AC CORE stores energy via the AC connection. An option for adding storage to an existing solar installation without replacing its inverter, subject to the connection requirements.
Everyday use
Solar generation and household demand rarely follow the same schedule. Storage holds energy for the hours when you need it. This example shows what to check over the course of a day.
Check how much energy remains in the battery. Household consumption is a separate measurement, supplied by a compatible energy meter.
AC CORE charges through its AC connection. Using PV surplus requires compatible metering and a suitable operating mode.
When solar generation falls, the main unit can supply stored energy within its output limits. Charge level and household demand determine how long it lasts.
The battery can continue supplying energy while charge level and operating settings allow it. A retained backup reserve leaves less energy for ordinary use. Neither nominal capacity nor a sunny afternoon guarantees supply until morning.
The existing PV inverter can remain if connection and control requirements are met. AC CORE's direct PV inputs are disabled at the factory. Their use requires a separate paid upgrade, which is not automatically included and is not required for AC-coupled storage.
Where direct PV is used, module voltage and current must match the main unit's input limits. Total Wp alone does not establish compatibility.
Follow the exact main unit's connection and installation instructions. Demand above its output limit is not covered by storage alone. B500 adds capacity, not inverter power.
This sequence explains the principle, not a yield forecast. Weather, panel orientation, loads, conversion losses, battery state and settings affect the result.
The energy path
Your existing solar inverter continues converting solar power. AC CORE adds a battery through the AC side, provided the electrical installation and control system are suitable.
The solar inverter feeds the household's AC network. AC CORE stores energy through that network.
5,024 Wh nominal energy
The inverter converts stored DC energy to AC. Grid-connected output is rated at 2,400 W for this model.
Simplified explanation of the storage path, not a wiring diagram. It does not show every operating mode or connection. Installation and backup requirements are separate.
A compatible energy meter reports household consumption or grid flow. The main unit can use these measurements for demand-based control. Battery status alone does not show the home's total consumption; meter compatibility and settings matter.
AC-coupled storage does not require direct-PV activation. AC CORE's direct PV inputs are disabled at the factory; using them requires a separate paid upgrade. It is not automatically included in this configuration.
Applications
Are you planning new panels or adding storage to an existing PV system? The connection path matters more than whether the panels sit on a balcony or a roof. These examples explain the options; they do not change your selected SunEnergyXT AC CORE.
SunEnergyXT 500 and 500 PRO accept compatible solar panels at their active PV inputs. The main unit combines solar charge controllers, battery and inverter. For a new or separate array, this provides a direct route to storage without a separate PV inverter for those panels.
Have module voltage, current and wiring checked against the main unit's limits. Combined Wp alone does not establish compatibility, and the balcony image does not establish a suitable electrical connection.
For your selected AC CORE, direct PV inputs are disabled at the factory. Using them requires a separate paid upgrade; the direct-PV example is not its standard configuration.
With AC-coupled storage, the existing PV inverter supplies the household AC network. AC CORE takes in energy through its AC connection. The inverter can remain if the connection and control requirements fit the system; compatibility must be checked for the actual installation.
A compatible energy meter provides household measurements for consumption-based control. Its model, measurement point, network connection and firmware belong in the planning. AC storage does not require activation of AC CORE's direct PV inputs.
A list of appliances is a useful planning tool, not proof that a storage system can supply them all. Record what runs at the same time and which loads you would want during an outage.
SunEnergyXT AC CORE · Technology
The model-specific datasheet specifies LiFePO4 chemistry and 314 Ah nominal battery capacity. The battery stores energy for later use and is rated for at least 10,000 charge/discharge cycles under the conditions below.
At least 10,000 cycles at 25 ± 2 °C, 80% depth of discharge, 0.5C charging / 0.5C discharging and 70% remaining capacity at end of life, according to the datasheet. These laboratory conditions do not establish a calendar lifespan or warranty.
SunEnergyXT AC CORE · Solar inputs
AC CORE's four direct-PV inputs are disabled at the factory. A separate paid upgrade service is required before use. The hardware values below do not mean that PV operation is included in your selection.
Module voltage, current and wiring must suit the inputs. Combined module wattage alone does not establish compatibility.
SunEnergyXT AC CORE · Protection
The current manufacturer datasheet lists an integrated automatic aerosol fire-extinguishing system for SunEnergyXT AC CORE.
Continue to follow the placement and safety instructions in the manual. An integrated fire-extinguishing system is not a promise to prevent every fire.
The datasheet specifies natural cooling, IP65 protection and an operating range of −20 °C to +55 °C. For this main unit, output is reduced above 45 °C.
Automatic battery heating supports operation at low temperatures; the system controls it without user intervention. Allow for its energy use and choose a sheltered, ventilated location with protected connections.

Storage sizing
Plan the energy you need over time and the loads running together separately.
kWhStorage capacity
Compare the energy used after sunset with the surplus available for charging. Choose capacity to match both, not just the number of people in your household.
kWOutput power
Check the main unit's output against appliances running at the same time. Adding battery capacity does not increase its inverter output.
Adding B500 batteries increases the capacity of SunEnergyXT AC CORE, not its inverter output. Check the permitted combination and available space before choosing additional batteries.
Start with two quantities: solar energy left after daytime consumption and energy used when generation falls. Household size alone cannot tell you how much storage is useful.
Use generation and consumption records from the same periods, including different seasons. Identify how much solar energy remains after immediate household use, then compare it with consumption after sunset. A larger battery cannot make up for missing solar generation.
Power in kW describes the load at a given moment. Energy in kWh adds up that demand over time. For a constant load, the calculation is:
1 kW × 1 h = 1 kWh
A constant 1 kW load uses 1 kWh in one hour. This is an energy calculation, not a battery-runtime promise. Usable energy, conversion losses, charge level, reserve and output limits still matter.
Compare the nominal-energy options in the capacity overview with your consumption records. Do not treat nominal energy as fully usable energy. Any backup reserve leaves less for everyday consumption. Separately, check the main unit's output against appliances running at the same time.
Capacity expansion
Need more energy for the evening? Add B500 batteries to your main unit as your storage needs grow.
One main unit can be expanded with up to five B500 batteries. Each B500 adds 5,024 Wh of nominal energy, not inverter power. Follow the manual's combination and installation requirements. Your selected quantity is shown in the configuration above.
Each illustration shows one main unit plus the stated number of B500 batteries. Quantity comparison only, not an installation plan or an indication of what is included in your order.
Calculated from 5,024 Wh per main unit and expansion battery. Actual usable energy and runtime depend on operating conditions, reserve settings and conversion losses.
Expanding with main units
B500 adds storage capacity. Additional main units also bring their own inverter.

Parallel and three-phase control are still announced as forthcoming by the manufacturer. A multi-unit setup needs verification of release, wiring and control requirements. The power sums above are not a promise of a usable shared output.
The manufacturer's 500-series page still lists parallel and three-phase control as forthcoming. The manual already describes a specific off-grid arrangement, but this is not permission for grid-parallel use. The figures shown are sums of individual rated outputs, not a promise of an available or approved combined system output.
Manual section 5.5 describes a separately available 3-to-1 off-grid parallel cable. It is exclusively for island operation; the manufacturer prohibits using it for grid-parallel operation. It is not the standard AC connection cable. Check the actual offer to see whether this accessory is included.
SunEnergyXT App
View battery status and energy flows in the SunEnergyXT app and adjust the operating mode to suit the main unit and firmware.
A PV symbol does not mean AC CORE's direct PV inputs are active. They are disabled at the factory and require a separate paid upgrade.
See the charge level and whether energy is being stored or discharged.
Available settings depend on the main unit and its firmware.
Household readings require a compatible meter at the appropriate measurement point.
Go to the app download page iOS and Android · Manufacturer website
The PV display concerns the main unit's solar inputs. It is not automatically the output of an existing rooftop inverter. AC CORE needs separate paid activation before its direct PV inputs can be used; B500 has none.
Charge level describes the battery's state. Charging or discharging power describes the energy flow at that moment. Neither value on its own predicts how long your appliances will run.
Grid import, export and household demand are different quantities. A compatible meter and its installation point determine which measurements are available for control. Pair and check the meter using the relevant instructions.
Metering and integration
A compatible meter supplies household measurements for consumption-based control. The app image does not mean a meter is included in your order.
Shelly 3EM · Shelly Pro 3EM · Shelly EM-50 · EcoTracker IR · EcoTracker P1 · bitShake
This manufacturer list is a starting point for checking compatibility, not a promise for every installation. Confirm the exact meter, interface, firmware and measurement point. “bitShake” names a product family, not a specific model. A meter is not automatically included.
Home Assistant integration requires separate setup. Check the supported main unit, firmware and current manufacturer instructions first.
According to the manufacturer, full app control uses a cloud connection. An internet connection is recommended for initial setup and is needed for firmware updates. Local control uses the documented mDNS / TCP interface, for example through a separately configured Home Assistant installation; it still requires a working local network and compatible firmware.
The manual describes Bluetooth Low Energy-assisted network setup, monitoring and changes to the power-supply mode. The example screen distinguishes PV, meter, grid, load and battery status: these are separate measurement points. Displays vary with connected devices, operating mode and software version.
Meter model, installation point, network connection and firmware must suit the system design.

Grid and backup operation
Grid-connected output and island-mode output are different operating specifications. A backup socket is not an automatic supply for every circuit in your home.
Section 6.2 of manual v2.2 describes these three states in UPS mode for suitable loads at the main unit's approved backup connection. PV contributes only through compatible, active direct-PV inputs. AC CORE's inputs are factory-disabled and require separate paid activation.
The manual describes the connected load being supplied by the battery and available PV generation. If these sources cannot supply enough power, the public grid supplements them.
The main unit automatically transfers the backup load to battery and available PV supply. Operation remains subject to the charge level, selected mode and load limits; this does not promise uninterrupted operation for every appliance.
When the grid returns, the system automatically switches back to grid operation, according to the manual. This sequence concerns the approved backup load, not an automatic transfer of every household circuit.
For the main units, the datasheets distinguish UPS mode at ≤10 ms from non-UPS mode at less than 2 seconds. These figures describe transfer timing, not how long the battery can supply a load.
Check the operating mode and the connected device's tolerance for interruptions. Do not infer suitability for medical, safety-critical or other interruption-sensitive equipment from the switching time alone.
The figures are not additive and are not approval for whole-home backup.
Sources: main-unit datasheets, pp. 1–2; manual v2.2, section 6.2 / PDF p. 35; the manufacturer's model FAQ for simultaneous grid and backup use.
Before installation
Device dimensions are only the starting point. The installation also needs a load-bearing surface, room for connections and service, ventilation and weather protection.
58 ± 1 kg
Include every additional B500 when assessing the load on the floor and fixings. The manual requires a stable, load-bearing location and vertical installation; horizontal, inverted or tilted placement is not permitted.
Plan access to the power button, status indicators, identification labels and connections. Use the mounting and securing arrangements specified for the actual configuration, not just the footprint shown in a product image.
Check dimensions in the datasheetHave a qualified electrician check the existing installation, protective measures and connection requirements against the model-specific manual before commissioning.
The manual requires a shaded location protected from direct sunlight, rain and snow, with sufficient ventilation and access for maintenance. A canopy may be needed. Keep the system away from combustible, explosive or corrosive materials and out of children's reach.
The specified installation altitude is below 2,000 m above sea level.
The stacking instructions specify more than 23 mm between the main unit and the wall. Their accompanying text specifies at least 88 mm between the expansion batteries and the wall so the main unit can be stacked above them.
These are arrangement-specific distances, not a complete ventilation or cable-clearance plan. Use the full manual for the selected mounting arrangement and keep the cooling surfaces and service access clear.
The manual requires external protective earthing and protected unused connectors. It separately identifies the earthing conductor and associated materials as items to be provided on site. Product selection alone does not verify the existing electrical installation.
Have the electrical connection and local requirements checked before commissioning. The product page is not an installation instruction.
Follow the model-specific manual for permitted placement, clearances, connections and electrical installation. A product image does not confirm compatibility with an existing installation.
The manufacturer specifies paid activation of the MPPT controllers for direct PV operation. Check the current activation terms separately; activation is not included merely by selecting AC CORE here.
The manual allows up to five B500 expansion batteries per main unit. Before changing the configuration, the system must be switched off and disconnected from all inputs and outputs. Switching it off alone is not sufficient when an input can restart it automatically.
Battery expansion is not a hot-swap operation. Follow the manual's sequence and securing requirements for the heavy modules.
These planning notes do not establish compliance for a particular site or market.
Good preparation keeps system design, placement, electrical connection and software setup distinct. Use this overview to prepare the discussion with a qualified electrical professional, not as wiring instructions.
Bring the exact main-unit model, existing inverter and panel data, consumption records and desired uses. Have the electrical professional assess the connection path, protection and measurement point. Define any backup loads separately rather than assuming the whole home will be supplied.
Record the available space, access route and proposed battery arrangement. Have weight, support, securing hardware, clearances and environmental conditions checked against the manual. Photos and measurements help prepare the assessment; they do not replace it.
Leave electrical work to the qualified professional, following the instructions for the exact model and configuration. PV, AC, expansion-battery and backup connections have different roles and limits. A product illustration or app setting cannot replace correct wiring and protection.
AC CORE's direct PV inputs remain disabled without the separate paid upgrade. App setup is not a substitute for that activation.
After the electrical checks, follow the manual for network and app setup. Coordinate the operating mode with the system plan. If using a compatible meter, check its measurement point, connection and displayed values with the installer; the software settings do not verify the electrical installation.
System components
Check the components for your planned system.
Modules supply DC energy.
Direct connection to AC CORE requires the separate paid PV activation. Adding panels to an order does not activate its inputs.
A module's Wp rating describes nominal solar-module power, not the storage system's AC output. Check the exact module's voltage and current, the intended wiring and the active PV inputs before choosing a quantity.
A mount must suit the panel frame and the actual mounting surface or railing.
Round and square railing profiles are different selections. Check dimensions, fasteners, load-bearing capacity and the mounting instructions; a selectable bracket is not automatically approved for every panel or balcony.
Panel mounts are not the mounting hardware used to secure the storage units.
The expansion battery adds 5,024 Wh of nominal energy per unit.
A main unit supports up to five B500 batteries according to the manual. Plan the total weight, stacking arrangement and securing hardware as well as the desired capacity.
A DC cable pair extends the solar connection; it is not an AC mains cable or a battery expansion connection.
Choose the required length and verify conductor size, electrical ratings, connector compatibility and routing for the actual installation.
The required AC connection must be assessed separately. A cable shown in a picture or listed in a generic manual does not confirm the contents of the selected merchant offer.
A compatible meter supplies consumption or grid measurements for demand-based control.
The manufacturer currently lists EcoTracker IR, among other devices; support still depends on the exact meter, installation point, firmware and configuration.
The manual lists the meter as separately available. An energy meter is not automatically a regulated German smart metering system, or iMSys, and it does not add battery capacity or output power.
The products and quantities are listed in the configurator above.

The storage class is not the same as usable energy. See the model-specific datasheet for detailed electrical values and operating conditions.
Manufacturer's model informationSource: model-specific manufacturer datasheet. DC battery ratings, AC charging, grid output and island output describe different operating paths and must not be added together. Transfer time is not a runtime guarantee or approval for whole-home backup. IP65 does not remove the installation, ventilation and weather-protection requirements.
The battery stores DC energy; the inverter connects it to the AC side. Solar input, battery charging and output ratings describe different parts of this process.
Functional description, not a wiring diagram. Port positions and connection procedures: manual v2.2, PDF pp. 13, 15, 19 and 28–33.
The main unit distinguishes PV, GRID, BACKUP, Wi-Fi, BLE, STATE and BATTERY. According to the manual, yellow at STATE indicates heating, blue indicates maintenance — state-of-charge calibration required — and red indicates a fault.
The main-unit datasheet also lists anti-islanding protection. This is separate from backup operation and is not a feature of a standalone B500.
Use the full indicator and flashing-pattern table before interpreting a signal. A colour alone does not diagnose the cause of a fault; follow the manual's troubleshooting and safety guidance.

Sources: model-specific datasheet, including its cycle-life footnote; manual v2.2, PDF pp. 7, 14–19, 33 and 35–37.
The datasheet recommends a charge/discharge cycle every three months and requires one after six months at the latest. If the system will stand unused, include this in your maintenance plan rather than treating it as maintenance-free.
The datasheet specifies −20 °C to +45 °C for one month of storage and 0 °C to +35 °C for long-term storage. These are storage conditions, not permission to operate or charge in any environment.
The manual requires a clean, dry environment without condensation. Follow its handling, connection and commissioning instructions when returning the system to use.

Before you order
The manufacturer describes software coordination of 500, 500 PRO or AC CORE with BK215 / BK215 Plus through its cloud strategy or a separately configured Home Assistant installation. A direct physical cable connection between these systems is not supported. This is not a B500 battery connection. Check the exact devices, firmware and control setup before planning a combined system.

Look at the energy you use after solar generation falls, not only your annual consumption. Compare this with the surplus available for charging. A larger battery does not create more solar energy. One main unit starts with 5,024 Wh nominal energy; B500 batteries add the same nominal energy per unit.
AC CORE is designed for adding storage on the AC side of an existing system. The existing solar inverter can remain in use, provided the installation, metering and connection plan are suitable. Send us its exact model and your planned setup before ordering if you are unsure.
No. Open-circuit voltage, operating voltage, current and the connection arrangement must match the exact input limits. The Wp rating alone does not establish compatibility. AC CORE's direct PV inputs are not enabled in its base configuration.
No. It is a separate product unless your selected item's delivery contents explicitly include it. For demand-based control, check compatibility with both the storage system and your household meter, as well as firmware and installation requirements.
The 500 has 800 W grid-connected output; 500 PRO and AC CORE have 2,400 W. 500 and 500 PRO provide active direct-PV inputs. AC CORE is intended for AC-coupled storage; its direct-PV controllers require separate paid activation. Connection and installation requirements still apply.
No. B500 adds storage capacity. The main unit determines the inverter output; additional batteries do not increase that rating.
No. The selected products and quantities are shown in the configuration. Check each product's delivery contents for included components. Installation is not added by the configurator.
Do not assume that every existing socket or circuit is suitable. Follow the exact model's installation instructions and have the electrical connection and local requirements checked before commissioning.
No. The manufacturer's multi-main illustration distributes up to 15 expansion batteries across three main units: up to five B500 per main unit. It does not increase the limit for one tower. This is a planning illustration, not a packing list or release confirmation for a coordinated system.
Check the model, firmware and document version before setup. An API document does not confirm coordinated multi-unit control.

SunEnergyXT 500
The battery, inverter and solar charge controllers are combined in one main unit. Compatible solar panels connect directly to the system, so stored energy can be used when you need it.
Everyday use
Solar generation and household demand rarely follow the same schedule. Storage holds energy for the hours when you need it. This example shows what to check over the course of a day.
Check how much energy remains in the battery. Household consumption is a separate measurement, supplied by a compatible energy meter.
The solar charge controllers use the panels' available generation. Charge level and settings determine how much energy the battery can take in.
When solar generation falls, the main unit can supply stored energy within its output limits. Charge level and household demand determine how long it lasts.
The battery can continue supplying energy while charge level and operating settings allow it. A retained backup reserve leaves less energy for ordinary use. Neither nominal capacity nor a sunny afternoon guarantees supply until morning.
500 and 500 PRO have active direct-PV inputs. Module voltage and current must fit the input limits; total Wp alone does not establish compatibility. AC-coupled retrofit with an existing PV inverter describes AC CORE, not a change to your selected SunEnergyXT 500.
Follow the exact main unit's connection and installation instructions. Demand above its output limit is not covered by storage alone. B500 adds capacity, not inverter power.
This sequence explains the principle, not a yield forecast. Weather, panel orientation, loads, conversion losses, battery state and settings affect the result.
The energy path
Solar charge controllers, a battery and an inverter work together in the main unit. Each has a different job: process solar input, store energy and provide AC output.
The panels supply DC power to the main unit's active MPPT inputs.
5,024 Wh nominal energy
The inverter converts stored DC energy to AC. Grid-connected output is rated at 800 W for this model.
Simplified explanation of the storage path, not a wiring diagram. It does not show every operating mode or connection. Installation and backup requirements are separate.
For 500 and 500 PRO, the manufacturer's FAQ gives a combined charging limit of 2,400 W: at 2,000 W from PV, up to 400 W can come from AC. Input capabilities therefore cannot simply be added together to predict battery charging speed. Charge level, temperature and operating settings also affect actual charging.
Manufacturer FAQ ↗ · Checked 21 September 2026. This example is specific to 500 / 500 PRO.
A compatible energy meter reports household consumption or grid flow. The main unit can use these measurements for demand-based control. Battery status alone does not show the home's total consumption; meter compatibility and settings matter.
The four MPPT inputs have separate voltage and current limits. Panel orientation is only part of the plan: check open-circuit voltage, operating voltage, current and the proposed wiring against the datasheet.
Applications
Are you planning new panels or adding storage to an existing PV system? The connection path matters more than whether the panels sit on a balcony or a roof. These examples explain the options; they do not change your selected SunEnergyXT 500.
SunEnergyXT 500 and 500 PRO accept compatible solar panels at their active PV inputs. The main unit combines solar charge controllers, battery and inverter. For a new or separate array, this provides a direct route to storage without a separate PV inverter for those panels.
Have module voltage, current and wiring checked against the main unit's limits. Combined Wp alone does not establish compatibility, and the balcony image does not establish a suitable electrical connection.
With AC-coupled storage, the existing PV inverter supplies the household AC network. AC CORE takes in energy through its AC connection. The inverter can remain if the connection and control requirements fit the system; compatibility must be checked for the actual installation.
A compatible energy meter provides household measurements for consumption-based control. Its model, measurement point, network connection and firmware belong in the planning. AC storage does not require activation of AC CORE's direct PV inputs.
This retrofit example describes AC CORE, not your selected SunEnergyXT 500. Compare the main units before deciding which connection path to use.
A list of appliances is a useful planning tool, not proof that a storage system can supply them all. Record what runs at the same time and which loads you would want during an outage.
SunEnergyXT 500 · Technology
The model-specific datasheet specifies LiFePO4 chemistry and 314 Ah nominal battery capacity. The battery stores energy for later use and is rated for at least 10,000 charge/discharge cycles under the conditions below.
At least 10,000 cycles at 25 ± 2 °C, 80% depth of discharge, 0.5C charging / 0.5C discharging and 70% remaining capacity at end of life, according to the datasheet. These laboratory conditions do not establish a calendar lifespan or warranty.
SunEnergyXT 500 · Solar inputs
Module voltage, current and wiring must suit the inputs. Combined module wattage alone does not establish compatibility.
SunEnergyXT 500 · Protection
The current manufacturer datasheet lists an integrated automatic aerosol fire-extinguishing system for SunEnergyXT 500.
Continue to follow the placement and safety instructions in the manual. An integrated fire-extinguishing system is not a promise to prevent every fire.
The datasheet specifies natural cooling, IP65 protection and an operating range of −20 °C to +55 °C. For this main unit, output is reduced above 45 °C.
Automatic battery heating supports operation at low temperatures; the system controls it without user intervention. Allow for its energy use and choose a sheltered, ventilated location with protected connections.

Storage sizing
Plan the energy you need over time and the loads running together separately.
kWhStorage capacity
Compare the energy used after sunset with the surplus available for charging. Choose capacity to match both, not just the number of people in your household.
kWOutput power
Check the main unit's output against appliances running at the same time. Adding battery capacity does not increase its inverter output.
Adding B500 batteries increases the capacity of SunEnergyXT 500, not its inverter output. Check the permitted combination and available space before choosing additional batteries.
Start with two quantities: solar energy left after daytime consumption and energy used when generation falls. Household size alone cannot tell you how much storage is useful.
Use generation and consumption records from the same periods, including different seasons. Identify how much solar energy remains after immediate household use, then compare it with consumption after sunset. A larger battery cannot make up for missing solar generation.
Power in kW describes the load at a given moment. Energy in kWh adds up that demand over time. For a constant load, the calculation is:
1 kW × 1 h = 1 kWh
A constant 1 kW load uses 1 kWh in one hour. This is an energy calculation, not a battery-runtime promise. Usable energy, conversion losses, charge level, reserve and output limits still matter.
Compare the nominal-energy options in the capacity overview with your consumption records. Do not treat nominal energy as fully usable energy. Any backup reserve leaves less for everyday consumption. Separately, check the main unit's output against appliances running at the same time.
Capacity expansion
Need more energy for the evening? Add B500 batteries to your main unit as your storage needs grow.
One main unit can be expanded with up to five B500 batteries. Each B500 adds 5,024 Wh of nominal energy, not inverter power. Follow the manual's combination and installation requirements. Your selected quantity is shown in the configuration above.
Each illustration shows one main unit plus the stated number of B500 batteries. Quantity comparison only, not an installation plan or an indication of what is included in your order.
Calculated from 5,024 Wh per main unit and expansion battery. Actual usable energy and runtime depend on operating conditions, reserve settings and conversion losses.
Expanding with main units
B500 adds storage capacity. Additional main units also bring their own inverter.

The manufacturer's 500-series page still lists parallel and three-phase control as forthcoming. The manual already describes a specific off-grid arrangement, but this is not permission for grid-parallel use. The figures shown are sums of individual rated outputs, not a promise of an available or approved combined system output.
Manual section 5.5 describes a separately available 3-to-1 off-grid parallel cable. It is exclusively for island operation; the manufacturer prohibits using it for grid-parallel operation. It is not the standard AC connection cable. Check the actual offer to see whether this accessory is included.
SunEnergyXT App
View battery status and energy flows in the SunEnergyXT app and adjust the operating mode to suit the main unit and firmware.
See the charge level and whether energy is being stored or discharged.
Available settings depend on the main unit and its firmware.
Household readings require a compatible meter at the appropriate measurement point.
Go to the app download page iOS and Android · Manufacturer website
The PV display concerns the main unit's solar inputs. It is not automatically the output of an existing rooftop inverter. AC CORE needs separate paid activation before its direct PV inputs can be used; B500 has none.
Charge level describes the battery's state. Charging or discharging power describes the energy flow at that moment. Neither value on its own predicts how long your appliances will run.
Grid import, export and household demand are different quantities. A compatible meter and its installation point determine which measurements are available for control. Pair and check the meter using the relevant instructions.
Metering and integration
A compatible meter supplies household measurements for consumption-based control. The app image does not mean a meter is included in your order.
Shelly 3EM · Shelly Pro 3EM · Shelly EM-50 · EcoTracker IR · EcoTracker P1 · bitShake
This manufacturer list is a starting point for checking compatibility, not a promise for every installation. Confirm the exact meter, interface, firmware and measurement point. “bitShake” names a product family, not a specific model. A meter is not automatically included.
Home Assistant integration requires separate setup. Check the supported main unit, firmware and current manufacturer instructions first.
According to the manufacturer, full app control uses a cloud connection. An internet connection is recommended for initial setup and is needed for firmware updates. Local control uses the documented mDNS / TCP interface, for example through a separately configured Home Assistant installation; it still requires a working local network and compatible firmware.
The manual describes Bluetooth Low Energy-assisted network setup, monitoring and changes to the power-supply mode. The example screen distinguishes PV, meter, grid, load and battery status: these are separate measurement points. Displays vary with connected devices, operating mode and software version.
Meter model, installation point, network connection and firmware must suit the system design.

Grid and backup operation
Grid-connected output and island-mode output are different operating specifications. A backup socket is not an automatic supply for every circuit in your home.
Section 6.2 of manual v2.2 describes these three states in UPS mode for suitable loads at the main unit's approved backup connection. PV contributes only through compatible, active direct-PV inputs.
The manual describes the connected load being supplied by the battery and available PV generation. If these sources cannot supply enough power, the public grid supplements them.
The main unit automatically transfers the backup load to battery and available PV supply. Operation remains subject to the charge level, selected mode and load limits; this does not promise uninterrupted operation for every appliance.
When the grid returns, the system automatically switches back to grid operation, according to the manual. This sequence concerns the approved backup load, not an automatic transfer of every household circuit.
For the main units, the datasheets distinguish UPS mode at ≤10 ms from non-UPS mode at less than 2 seconds. These figures describe transfer timing, not how long the battery can supply a load.
Check the operating mode and the connected device's tolerance for interruptions. Do not infer suitability for medical, safety-critical or other interruption-sensitive equipment from the switching time alone.
The figures are not additive and are not approval for whole-home backup.
Sources: main-unit datasheets, pp. 1–2; manual v2.2, section 6.2 / PDF p. 35; the manufacturer's model FAQ for simultaneous grid and backup use.
Before installation
Device dimensions are only the starting point. The installation also needs a load-bearing surface, room for connections and service, ventilation and weather protection.
58 ± 1 kg
Include every additional B500 when assessing the load on the floor and fixings. The manual requires a stable, load-bearing location and vertical installation; horizontal, inverted or tilted placement is not permitted.
Plan access to the power button, status indicators, identification labels and connections. Use the mounting and securing arrangements specified for the actual configuration, not just the footprint shown in a product image.
Check dimensions in the datasheetHave a qualified electrician check the existing installation, protective measures and connection requirements against the model-specific manual before commissioning.
The manual requires a shaded location protected from direct sunlight, rain and snow, with sufficient ventilation and access for maintenance. A canopy may be needed. Keep the system away from combustible, explosive or corrosive materials and out of children's reach.
The specified installation altitude is below 2,000 m above sea level.
The stacking instructions specify more than 23 mm between the main unit and the wall. Their accompanying text specifies at least 88 mm between the expansion batteries and the wall so the main unit can be stacked above them.
These are arrangement-specific distances, not a complete ventilation or cable-clearance plan. Use the full manual for the selected mounting arrangement and keep the cooling surfaces and service access clear.
The manual requires external protective earthing and protected unused connectors. It separately identifies the earthing conductor and associated materials as items to be provided on site. Product selection alone does not verify the existing electrical installation.
Have the electrical connection and local requirements checked before commissioning. The product page is not an installation instruction.
Follow the model-specific manual for permitted placement, clearances, connections and electrical installation. A product image does not confirm compatibility with an existing installation.
A backup outlet is not an automatic whole-home supply. Its permitted loads, combined output limits and connection requirements are described in the manual.
The manual allows up to five B500 expansion batteries per main unit. Before changing the configuration, the system must be switched off and disconnected from all inputs and outputs. Switching it off alone is not sufficient when an input can restart it automatically.
Battery expansion is not a hot-swap operation. Follow the manual's sequence and securing requirements for the heavy modules.
These planning notes do not establish compliance for a particular site or market.
Good preparation keeps system design, placement, electrical connection and software setup distinct. Use this overview to prepare the discussion with a qualified electrical professional, not as wiring instructions.
Bring the exact main-unit model, existing inverter and panel data, consumption records and desired uses. Have the electrical professional assess the connection path, protection and measurement point. Define any backup loads separately rather than assuming the whole home will be supplied.
Record the available space, access route and proposed battery arrangement. Have weight, support, securing hardware, clearances and environmental conditions checked against the manual. Photos and measurements help prepare the assessment; they do not replace it.
Leave electrical work to the qualified professional, following the instructions for the exact model and configuration. PV, AC, expansion-battery and backup connections have different roles and limits. A product illustration or app setting cannot replace correct wiring and protection.
After the electrical checks, follow the manual for network and app setup. Coordinate the operating mode with the system plan. If using a compatible meter, check its measurement point, connection and displayed values with the installer; the software settings do not verify the electrical installation.
System components
Check the components for your planned system.
Modules supply DC energy.
A module's Wp rating describes nominal solar-module power, not the storage system's AC output. Check the exact module's voltage and current, the intended wiring and the active PV inputs before choosing a quantity.
A mount must suit the panel frame and the actual mounting surface or railing.
Round and square railing profiles are different selections. Check dimensions, fasteners, load-bearing capacity and the mounting instructions; a selectable bracket is not automatically approved for every panel or balcony.
Panel mounts are not the mounting hardware used to secure the storage units.
The expansion battery adds 5,024 Wh of nominal energy per unit.
A main unit supports up to five B500 batteries according to the manual. Plan the total weight, stacking arrangement and securing hardware as well as the desired capacity.
A DC cable pair extends the solar connection; it is not an AC mains cable or a battery expansion connection.
Choose the required length and verify conductor size, electrical ratings, connector compatibility and routing for the actual installation.
The required AC connection must be assessed separately. A cable shown in a picture or listed in a generic manual does not confirm the contents of the selected merchant offer.
A compatible meter supplies consumption or grid measurements for demand-based control.
The manufacturer currently lists EcoTracker IR, among other devices; support still depends on the exact meter, installation point, firmware and configuration.
The manual lists the meter as separately available. An energy meter is not automatically a regulated German smart metering system, or iMSys, and it does not add battery capacity or output power.

Look at the energy you use after solar generation falls, not only your annual consumption. Compare this with the surplus available for charging. A larger battery does not create more solar energy. One main unit starts with 5,024 Wh nominal energy; B500 batteries add the same nominal energy per unit.
AC CORE is designed for adding storage on the AC side of an existing system. The existing solar inverter can remain in use, provided the installation, metering and connection plan are suitable. Send us its exact model and your planned setup before ordering if you are unsure.
No. Open-circuit voltage, operating voltage, current and the connection arrangement must match the exact input limits. The Wp rating alone does not establish compatibility. AC CORE's direct PV inputs are not enabled in its base configuration.
No. It is a separate product unless your selected item's delivery contents explicitly include it. For demand-based control, check compatibility with both the storage system and your household meter, as well as firmware and installation requirements.
The 500 has 800 W grid-connected output; 500 PRO and AC CORE have 2,400 W. 500 and 500 PRO provide active direct-PV inputs. AC CORE is intended for AC-coupled storage; its direct-PV controllers require separate paid activation. Connection and installation requirements still apply.
No. B500 adds storage capacity. The main unit determines the inverter output; additional batteries do not increase that rating.
No. The selected products and quantities are shown in the configuration. Check each product's delivery contents for included components. Installation is not added by the configurator.
Do not assume that every existing socket or circuit is suitable. Follow the exact model's installation instructions and have the electrical connection and local requirements checked before commissioning.
No. The manufacturer's multi-main illustration distributes up to 15 expansion batteries across three main units: up to five B500 per main unit. It does not increase the limit for one tower. This is a planning illustration, not a packing list or release confirmation for a coordinated system.
Check the model, firmware and document version before setup. An API document does not confirm coordinated multi-unit control.

Grid and backup operation
Grid-connected output and island-mode output are different operating specifications. A backup socket is not an automatic supply for every circuit in your home.
Section 6.2 of manual v2.2 describes these three states in UPS mode for suitable loads at the main unit's approved backup connection. PV contributes only through compatible, active direct-PV inputs.
The manual describes the connected load being supplied by the battery and available PV generation. If these sources cannot supply enough power, the public grid supplements them.
The main unit automatically transfers the backup load to battery and available PV supply. Operation remains subject to the charge level, selected mode and load limits; this does not promise uninterrupted operation for every appliance.
When the grid returns, the system automatically switches back to grid operation, according to the manual. This sequence concerns the approved backup load, not an automatic transfer of every household circuit.
For the main units, the datasheets distinguish UPS mode at ≤10 ms from non-UPS mode at less than 2 seconds. These figures describe transfer timing, not how long the battery can supply a load.
Check the operating mode and the connected device's tolerance for interruptions. Do not infer suitability for medical, safety-critical or other interruption-sensitive equipment from the switching time alone.
The figures are not additive and are not approval for whole-home backup.

Before installation
Device dimensions are only the starting point. The installation also needs a load-bearing surface, room for connections and service, ventilation and weather protection.
58 ± 1 kg
Include every additional B500 when assessing the load on the floor and fixings. The manual requires a stable, load-bearing location and vertical installation; horizontal, inverted or tilted placement is not permitted.
Plan access to the power button, status indicators, identification labels and connections. Use the mounting and securing arrangements specified for the actual configuration, not just the footprint shown in a product image.
Check dimensions in the datasheetHave a qualified electrician check the existing installation, protective measures and connection requirements against the model-specific manual before commissioning.
The manual requires a shaded location protected from direct sunlight, rain and snow, with sufficient ventilation and access for maintenance. A canopy may be needed. Keep the system away from combustible, explosive or corrosive materials and out of children's reach.
The specified installation altitude is below 2,000 m above sea level.
The stacking instructions specify more than 23 mm between the main unit and the wall. Their accompanying text specifies at least 88 mm between the expansion batteries and the wall so the main unit can be stacked above them.
These are arrangement-specific distances, not a complete ventilation or cable-clearance plan. Use the full manual for the selected mounting arrangement and keep the cooling surfaces and service access clear.
The manual requires external protective earthing and protected unused connectors. It separately identifies the earthing conductor and associated materials as items to be provided on site. Product selection alone does not verify the existing electrical installation.
Have the electrical connection and local requirements checked before commissioning. The product page is not an installation instruction.
Follow the model-specific manual for permitted placement, clearances, connections and electrical installation. A product image does not confirm compatibility with an existing installation.
A backup outlet is not an automatic whole-home supply. Its permitted loads, combined output limits and connection requirements are described in the manual.
The manual allows up to five B500 expansion batteries per main unit. Before changing the configuration, the system must be switched off and disconnected from all inputs and outputs. Switching it off alone is not sufficient when an input can restart it automatically.
Battery expansion is not a hot-swap operation. Follow the manual's sequence and securing requirements for the heavy modules.

If using a compatible meter, check its measurement point, connection and displayed values with the installer; the software settings do not verify the electrical installation.
System components
Check the components for your planned system.
Modules supply DC energy.
A module's Wp rating describes nominal solar-module power, not the storage system's AC output. Check the exact module's voltage and current, the intended wiring and the active PV inputs before choosing a quantity.
A mount must suit the panel frame and the actual mounting surface or railing.
Round and square railing profiles are different selections. Check dimensions, fasteners, load-bearing capacity and the mounting instructions; a selectable bracket is not automatically approved for every panel or balcony.
Panel mounts are not the mounting hardware used to secure the storage units.
The expansion battery adds 5,024 Wh of nominal energy per unit.
A main unit supports up to five B500 batteries according to the manual. Plan the total weight, stacking arrangement and securing hardware as well as the desired capacity.
A DC cable pair extends the solar connection; it is not an AC mains cable or a battery expansion connection.
Choose the required length and verify conductor size, electrical ratings, connector compatibility and routing for the actual installation.
The required AC connection must be assessed separately. A cable shown in a picture or listed in a generic manual does not confirm the contents of the selected merchant offer.
A compatible meter supplies consumption or grid measurements for demand-based control.
The manufacturer currently lists EcoTracker IR, among other devices; support still depends on the exact meter, installation point, firmware and configuration.
The manual lists the meter as separately available. An energy meter is not automatically a regulated German smart metering system, or iMSys, and it does not add battery capacity or output power.

Before you order
The manufacturer describes software coordination of 500, 500 PRO or AC CORE with BK215 / BK215 Plus through its cloud strategy or a separately configured Home Assistant installation. A direct physical cable connection between these systems is not supported. This is not a B500 battery connection. Check the exact devices, firmware and control setup before planning a combined system.

Look at the energy you use after solar generation falls, not only your annual consumption. Compare this with the surplus available for charging. A larger battery does not create more solar energy. One main unit starts with 5,024 Wh nominal energy; B500 batteries add the same nominal energy per unit.
AC CORE is designed for adding storage on the AC side of an existing system. The existing solar inverter can remain in use, provided the installation, metering and connection plan are suitable. Send us its exact model and your planned setup before ordering if you are unsure.
No. Open-circuit voltage, operating voltage, current and the connection arrangement must match the exact input limits. The Wp rating alone does not establish compatibility. AC CORE's direct PV inputs are not enabled in its base configuration.
No. It is a separate product unless your selected item's delivery contents explicitly include it. For demand-based control, check compatibility with both the storage system and your household meter, as well as firmware and installation requirements.
The 500 has 800 W grid-connected output; 500 PRO and AC CORE have 2,400 W. 500 and 500 PRO provide active direct-PV inputs. AC CORE is intended for AC-coupled storage; its direct-PV controllers require separate paid activation. Connection and installation requirements still apply.
No. B500 adds storage capacity. The main unit determines the inverter output; additional batteries do not increase that rating.
No. The selected products and quantities are shown in the configuration. Check each product's delivery contents for included components. Installation is not added by the configurator.
Do not assume that every existing socket or circuit is suitable. Follow the exact model's installation instructions and have the electrical connection and local requirements checked before commissioning.
No. The manufacturer's multi-main illustration distributes up to 15 expansion batteries across three main units: up to five B500 per main unit. It does not increase the limit for one tower. This is a planning illustration, not a packing list or release confirmation for a coordinated system.
Check the model, firmware and document version before setup. An API document does not confirm coordinated multi-unit control.

SunEnergyXT B500
B500 expands the storage capacity of a compatible SunEnergyXT main unit. It is an additional battery, not a standalone inverter or complete storage system.
Everyday use
Solar generation and household demand rarely follow the same schedule. Storage holds energy for the hours when you need it. This example shows what to check over the course of a day.
Check how much energy remains in the battery. Household consumption is a separate measurement, supplied by a compatible energy meter.
B500 receives energy through the main unit. Whether it comes from direct PV or an AC-coupled system depends on that unit and its configuration.
When solar generation falls, the main unit can supply stored energy within its output limits. Charge level and household demand determine how long it lasts.
The battery can continue supplying energy while charge level and operating settings allow it. A retained backup reserve leaves less energy for ordinary use. Neither nominal capacity nor a sunny afternoon guarantees supply until morning.
B500 has no separate PV or grid connection and cannot retrofit an existing PV inverter on its own. It needs a compatible main unit: 500 and 500 PRO offer active direct-PV inputs; AC CORE uses the AC path, with direct PV requiring separate paid activation.
Where direct PV is used, module voltage and current must match the main unit's input limits. Total Wp alone does not establish compatibility.
Follow the exact main unit's connection and installation instructions. Demand above its output limit is not covered by storage alone. B500 adds capacity, not inverter power.
This sequence explains the principle, not a yield forecast. Weather, panel orientation, loads, conversion losses, battery state and settings affect the result.
The energy path
The main unit controls the system. B500 provides additional battery capacity through its expansion connection.
Charging and control come from the main unit, not a separate PV input on B500.
5,024 Wh nominal energy
The main unit's inverter rating stays the same. The additional energy is available through that unit.
Simplified explanation of the storage path, not a wiring diagram. It does not show every operating mode or connection. Installation and backup requirements are separate.
A compatible energy meter reports household consumption or grid flow. The main unit can use these measurements for demand-based control. Battery status alone does not show the home's total consumption; meter compatibility and settings matter.
Use the battery expansion arrangement specified for the main unit. B500 cannot be connected directly to household AC or solar panels.
Applications
Are you planning new panels or adding storage to an existing PV system? The connection path matters more than whether the panels sit on a balcony or a roof. These examples explain the options; they do not change your selected SunEnergyXT B500.
SunEnergyXT 500 and 500 PRO accept compatible solar panels at their active PV inputs. The main unit combines solar charge controllers, battery and inverter. For a new or separate array, this provides a direct route to storage without a separate PV inverter for those panels.
Have module voltage, current and wiring checked against the main unit's limits. Combined Wp alone does not establish compatibility, and the balcony image does not establish a suitable electrical connection.
B500 cannot accept panels on its own. The compatible main unit provides the PV connection; B500 adds storage capacity.
With AC-coupled storage, the existing PV inverter supplies the household AC network. AC CORE takes in energy through its AC connection. The inverter can remain if the connection and control requirements fit the system; compatibility must be checked for the actual installation.
A compatible energy meter provides household measurements for consumption-based control. Its model, measurement point, network connection and firmware belong in the planning. AC storage does not require activation of AC CORE's direct PV inputs.
B500 alone is not an AC retrofit system. It needs a compatible main unit and increases capacity, not that unit's inverter output.
A list of appliances is a useful planning tool, not proof that a storage system can supply them all. Record what runs at the same time and which loads you would want during an outage.
SunEnergyXT B500 · Technology
The model-specific datasheet specifies LiFePO4 chemistry and 314 Ah nominal battery capacity. The battery stores energy for later use and is rated for at least 10,000 charge/discharge cycles under the conditions below.
At least 10,000 cycles at 25 ± 2 °C, 80% depth of discharge, 0.5C charging / 0.5C discharging and 70% remaining capacity at end of life, according to the datasheet. These laboratory conditions do not establish a calendar lifespan or warranty.
B500 connects through the system's battery expansion interfaces. It does not add an MPPT controller, an AC grid connection or a backup socket. Its DC battery ratings must not be treated as additional AC inverter output.
Read the technical datasheetSunEnergyXT B500 · Protection
The current manufacturer datasheet lists an integrated automatic aerosol fire-extinguishing system for SunEnergyXT B500.
Continue to follow the placement and safety instructions in the manual. An integrated fire-extinguishing system is not a promise to prevent every fire.
The datasheet specifies natural cooling, IP65 protection and an operating range of −20 °C to +55 °C.
Automatic battery heating supports operation at low temperatures; the system controls it without user intervention. Allow for its energy use and choose a sheltered, ventilated location with protected connections.

Storage sizing
Plan the energy you need over time and the loads running together separately.
kWhStorage capacity
Compare the energy used after sunset with the surplus available for charging. Choose capacity to match both, not just the number of people in your household.
kWOutput power
Check the main unit's output against appliances running at the same time. Adding battery capacity does not increase its inverter output.
Your selected B500 adds energy capacity to a compatible main unit. It cannot increase that unit's power limit or operate as a standalone system.
Start with two quantities: solar energy left after daytime consumption and energy used when generation falls. Household size alone cannot tell you how much storage is useful.
Use generation and consumption records from the same periods, including different seasons. Identify how much solar energy remains after immediate household use, then compare it with consumption after sunset. A larger battery cannot make up for missing solar generation.
Power in kW describes the load at a given moment. Energy in kWh adds up that demand over time. For a constant load, the calculation is:
1 kW × 1 h = 1 kWh
A constant 1 kW load uses 1 kWh in one hour. This is an energy calculation, not a battery-runtime promise. Usable energy, conversion losses, charge level, reserve and output limits still matter.
Compare the nominal-energy options in the capacity overview with your consumption records. Do not treat nominal energy as fully usable energy. Any backup reserve leaves less for everyday consumption. Separately, check the main unit's output against appliances running at the same time.
Capacity expansion
Need more energy for the evening? Add B500 batteries to your main unit as your storage needs grow.
One main unit can be expanded with up to five B500 batteries. Each B500 adds 5,024 Wh of nominal energy, not inverter power. Follow the manual's combination and installation requirements. The examples below compare storage capacities; they do not specify the quantity supplied with this product.
Each illustration shows one main unit plus the stated number of B500 batteries. Quantity comparison only, not an installation plan or an indication of what is included in your order.

Modules supply DC energy.
Solar panels do not connect to B500; compatibility is determined by the main unit.
A module's Wp rating describes nominal solar-module power, not the storage system's AC output. Check the exact module's voltage and current, the intended wiring and the active PV inputs before choosing a quantity.
A mount must suit the panel frame and the actual mounting surface or railing.
Round and square railing profiles are different selections. Check dimensions, fasteners, load-bearing capacity and the mounting instructions; a selectable bracket is not automatically approved for every panel or balcony.
Panel mounts are not the mounting hardware used to secure the storage units.
The expansion battery adds 5,024 Wh of nominal energy per unit.
A main unit supports up to five B500 batteries according to the manual. Plan the total weight, stacking arrangement and securing hardware as well as the desired capacity.
A DC cable pair extends the solar connection; it is not an AC mains cable or a battery expansion connection.
Choose the required length and verify conductor size, electrical ratings, connector compatibility and routing for the actual installation.
The required AC connection must be assessed separately. A cable shown in a picture or listed in a generic manual does not confirm the contents of the selected merchant offer.
A compatible meter supplies consumption or grid measurements for demand-based control.
The manufacturer currently lists EcoTracker IR, among other devices; support still depends on the exact meter, installation point, firmware and configuration.
The manual lists the meter as separately available. An energy meter is not automatically a regulated German smart metering system, or iMSys, and it does not add battery capacity or output power.
Refer to the B500 product description for delivery contents. Illustrations of main units and accessories do not define what is supplied with this product.
View B500 product detailsB500 is an expansion battery for a compatible main unit, not a standalone storage system. Check your main unit and the manual's combination and installation requirements before ordering.
Each accessory's current product data and installation instructions remain decisive for compatibility and delivery contents.

SunEnergyXT B500
The storage class is not the same as usable energy. See the model-specific datasheet for detailed electrical values and operating conditions.
Manufacturer's model informationSource: model-specific manufacturer datasheet. DC battery ratings, AC charging, grid output and island output describe different operating paths and must not be added together. Transfer time is not a runtime guarantee or approval for whole-home backup. IP65 does not remove the installation, ventilation and weather-protection requirements.
B500 stores energy within the system. Power conversion, direct solar connections and system control remain with the main unit.
The manual distinguishes the battery expansion interfaces from the main unit's AC and PV ports. B500 has its own power button and status indicators for operation, communication, balancing and battery state; it is not an independently controlled AC storage system.
Functional description, not a wiring diagram. Port positions and connection procedures: manual v2.2, PDF pp. 13, 15, 19 and 28–33.
B500 has POWER, COM, MODE, STATE and BATTERY indicators. According to the manual, blue at MODE indicates active balancing, while yellow at STATE indicates battery heating.
Use the full indicator and flashing-pattern table before interpreting a signal. A colour alone does not diagnose the cause of a fault; follow the manual's troubleshooting and safety guidance.

Sources: model-specific datasheet, including its cycle-life footnote; manual v2.2, PDF pp. 7, 14–19, 33 and 35–37.
The datasheet recommends a charge/discharge cycle every three months and requires one after six months at the latest. If the system will stand unused, include this in your maintenance plan rather than treating it as maintenance-free.
The datasheet specifies −20 °C to +45 °C for one month of storage and 0 °C to +35 °C for long-term storage. These are storage conditions, not permission to operate or charge in any environment.
The manual requires a clean, dry environment without condensation. Follow its handling, connection and commissioning instructions when returning the system to use.

Before you order
The manufacturer describes software coordination of 500, 500 PRO or AC CORE with BK215 / BK215 Plus through its cloud strategy or a separately configured Home Assistant installation. A direct physical cable connection between these systems is not supported. This is not a B500 battery connection. Check the exact devices, firmware and control setup before planning a combined system.

Look at the energy you use after solar generation falls, not only your annual consumption. Compare this with the surplus available for charging. A larger battery does not create more solar energy. One main unit starts with 5,024 Wh nominal energy; B500 batteries add the same nominal energy per unit.
AC CORE is designed for adding storage on the AC side of an existing system. The existing solar inverter can remain in use, provided the installation, metering and connection plan are suitable. Send us its exact model and your planned setup before ordering if you are unsure.
No. Open-circuit voltage, operating voltage, current and the connection arrangement must match the exact input limits. The Wp rating alone does not establish compatibility. AC CORE's direct PV inputs are not enabled in its base configuration.
No. It is a separate product unless your selected item's delivery contents explicitly include it. For demand-based control, check compatibility with both the storage system and your household meter, as well as firmware and installation requirements.
The 500 has 800 W grid-connected output; 500 PRO and AC CORE have 2,400 W. 500 and 500 PRO provide active direct-PV inputs. AC CORE is intended for AC-coupled storage; its direct-PV controllers require separate paid activation. Connection and installation requirements still apply.
No. B500 adds storage capacity. The main unit determines the inverter output; additional batteries do not increase that rating.
The illustrations explain component functions, not delivery contents. Check the B500 product description for what is supplied; do not infer included accessories or services from the images.
Do not assume that every existing socket or circuit is suitable. Follow the exact model's installation instructions and have the electrical connection and local requirements checked before commissioning.
No. The manufacturer's multi-main illustration distributes up to 15 expansion batteries across three main units: up to five B500 per main unit. It does not increase the limit for one tower. This is a planning illustration, not a packing list or release confirmation for a coordinated system.
Check the model, firmware and document version before setup. An API document does not confirm coordinated multi-unit control.

Erweiterbar ausschließlich mit dem SunEnergyXT B500, kompatibel mit 500, 500 PRO und 500 PRO AC Core; höchstens 5 Erweiterungsspeicher je Kopfspeicher. Speicher anderer Hersteller werden nicht erkannt.
Der B500 ist ein Erweiterungsspeicher ohne eigenen Wechselrichter, ohne PV-Eingänge und ohne AC-Anschlüsse. Er funktioniert nur zusammen mit einem SunEnergyXT 500, 500 PRO oder 500 PRO AC Core Kopfspeicher.
Zusätzliche Versorgungsstrategien in der SunEnergyXT App erfordern ein Energiemessgerät aus der Kompatibilitätsliste: www.sunenergyxt.com/komponenten. Andere Messgeräte lassen sich gegebenenfalls über kompatible Smart-Home-Systeme einbinden und die Steuerung erfolgt dann lokal und nicht über die App.
Für die Garantie ist keine Internetverbindung erforderlich. Softwareaktualisierungen, Ferndiagnose und App-Funktionen setzen eine Internetverbindung voraus.
Integrierte Heizfunktion: Bei Zelltemperaturen unter 0 °C werden die Batteriezellen automatisch vorgewärmt. Bis zum Erreichen der Betriebstemperatur stehen Lade- und Entladeleistung nur eingeschränkt zur Verfügung; Dauer und Ausmaß hängen unter anderem von Umgebungstemperatur, PV-Leistung und Zahl der Speicher ab. Oberhalb von 45 °C wird die Leistung reduziert.
Für jedes Gerät werden Softwareaktualisierungen, die zum Erhalt der Sicherheit und der in der Bedienungsanleitung beschriebenen Funktionen erforderlich sind, mindestens für die reguläre Dauer der jeweiligen Herstellergarantie bereitgestellt: fünf Jahre für BK215, BK215 PLUS, B215 und B215 PLUS, zehn Jahre für 500, 500 PRO, 500 PRO AC Core und B500. Für den EV3600 werden Softwareaktualisierungen abweichend von seiner zweijährigen Garantiedauer mindestens fünf Jahre bereitgestellt. Diese Zeiträume gelten auch, wenn sich die Garantiedauer wegen einer Aufstellung in Küstennähe nach Artikel 3.1 der jeweiligen Garantieerklärung verkürzt. Beginn und Nachweis des Zeitraums richten sich nach Artikel 3 der jeweiligen Garantieerklärung; bei Weiterverkauf geht der verbleibende Zeitraum auf den Erwerber über.
Der Hersteller kann die Bereitstellung verlängern; eine Verkürzung des einmal angegebenen Zeitraums erfolgt nicht. Vor Erreichen des Endes werden die Nutzer informiert.
Diese Angabe lässt die gesetzlichen Gewährleistungsrechte des Verbrauchers gegenüber seinem Verkäufer, einschließlich der Aktualisierungspflicht bei Waren mit digitalen Elementen, unberührt.
Der Hersteller stellt für die genannten Produkte Softwareaktualisierungen einschließlich Sicherheitsaktualisierungen bereit. Die Auslieferung erfolgt über die Netzwerkverbindung des Geräts; eine bestehende Netzwerkverbindung ist hierfür Voraussetzung. Beim EV3600 und bei Erweiterungsspeichern erfolgt sie über den Kopfspeicher.

Die Kapazitätszusage gilt, bis der kumulierte Energiedurchsatz der Batterieeinheit das 8.000-fache ihrer Nennenergie erreicht hat; das entspricht 10.000 Ladezyklen bei einer Entladetiefe von 80 %, den Referenzbedingungen der im Datenblatt angegebenen Zyklenlebensdauer. Maßgeblich ist der vom Batteriemanagement erfasste Energiedurchsatz, den der Garantiegeber Ihnen auf Anfrage mitteilt. Bei einem Verbund aus Kopfspeicher und Erweiterungsspeichern gilt die Kapazitätszusage für jede Batterieeinheit gesondert.
Nutzbare Speicherkapazität ist die Energiemenge, die der vollständig geladenen Batterieeinheit über den gesamten vom Batteriemanagement freigegebenen Ladezustandsbereich bis zur Abschaltung durch das Batteriemanagement entnommen werden kann; nutzerseitig eingestellte Ladegrenzen bleiben außer Betracht. Sie wird an den Batterieklemmen (gleichstromseitig) oder anhand der vom Batteriemanagement bilanzierten Entladeenergie ermittelt, bei einer Zelltemperatur von 25 °C ± 2 °C und einer konstanten Entladeleistung von 0,2 C (rund 1.000 W je Batterieeinheit). Die Messung führt der Garantiegeber oder ein von ihm autorisierter Servicebetrieb unentgeltlich durch; Sie erhalten ein Messprotokoll. Der vom Batteriemanagement ausgewiesene Kapazitätswert dient der Vorprüfung und ersetzt die Messung nicht.
Die Kapazitätszusage endet mit dem Ablauf der Garantiedauer oder mit Erreichen des vorgenannten Energiedurchsatzes, je nachdem, welches Ereignis früher eintritt. Die Garantiedauer nach Artikel 3 und die Zusage nach Artikel 2.1 bleiben von der Durchsatzgrenze unberührt.
