Was kann die neue Plus-Version der SunEnergyXT-Speicher?

BK215 rated "very good" in comprehensive solar power storage system test

This is how the editorial team of Home & Smart rated our storage unit: "The BK215 storage unit offers an impressive storage capacity of 2.15 kWh, which can be expanded with up to three B215 additional modules to a total of 8.6 kWh, making it one of the absolute top contenders. (...) During our test, all components could be easily plugged together and wired. Additionally, the connection with the manufacturer's app worked significantly faster than with other test storage units. (...) As a supplement to the practical test, we also conducted a brief check of the manufacturer's customer service, contacting them both in writing via email and over the phone. In both cases, we benefited from short response times and encountered friendly staff, which we consider a clear advantage. (...) Due to its ease of use and high storage capacity, we can recommend the BK215 to anyone looking to store a large amount of energy long-term."

The editorial team's conclusion: “An indoor- or outdoor-usable solution for comprehensive power storage.”

Customer reviews

Here's how our customers rate their experience with the SunEnergyXT system:

Simply thrilled. I want to take this opportunity to praise the SunEnergyXT support! It's just great how quickly and smoothly they help you. Very rare these days but so important, especially with DIY Solar. Thumbs up from me, and keep it up.

— Kai Ed K.

The storage system can be easily integrated into an existing plug-in PV plant and can also be expanded later on. Technical questions are answered very quickly by the great support team.

— Thomas F.

With SunEnergyXT, there is NO longer a single argument for not starting with PV. The SunEnergyXT storage system is the only system that can be individually adapted to your own needs and possibilities on both the consumption and generation side. Everything is possible, from very small to a real PV system. The support and community are unbelievably good!

— Lutz R.

Great system that is very easy to put together. Plus a support that helps quickly at all times.

— Enrique M.

SunEnergyXT's modular power storage system - it's really that simple!

Kompatibilität zwischen Plus-Version und 1. Generation

icon

Grundlegende Kompatibilität zwischen Plus-Version und 1. Generation

Grundsätzlich sind beide Speicher-Versionen miteinander kompatibel. So kann zum Beispiel ein BK215 mit einem oder mehreren B215 Plus Speichern betrieben werden. Ein BK215 Plus kann hingegen keine B215 Erweiterungsspeicher steuern.

icon

Einschränkungen bei der physischen Erweiterbarkeit

Bei der physischen Erweiterbarkeit gibt es aber eine Einschränkung. So kann ein regulärer BK215 Kopfspeicher weiterhin nur drei B215 Erweiterungsspeicher steuern. Dies ändert sich auch durch das Hinzufügen eines oder mehrerer B215 Plus Erweiterungsspeicher nicht. Für die volle, physische Erweiterung der Gesamtspeicherleistung auf mehr als 8,6 kWh sind somit Speichertürme aus Plus-Speichern Voraussetzung.

Smarte Multi-Bereiche-Strategie für Speichertürme-Kombination

Über die smarte Multi-Bereiche-Strategie können aber weiter problemlos mehrere Speichertürme in einem Steuerbereich per App kombiniert werden, die dann gemeinsam basierend auf den Daten eines Energiemessgerätes gesteuert werden.
