All technical data and detailed information about our LiFePO4 battery storage systems can be found in the respective categories below this description.
For correct communication, the battery's data protocol must be configured for the inverter manufacturer. By default, it is configured for data communication with Victron inverters. If you are not using a Victron inverter, please inform us of your inverter type immediately after placing your order so that we can configure the battery for communication with your inverter. Further information can be found in the "Data Communication" section.
Quality begins within – and remains traceable with us.
The battery cells are THE The heart of a battery, and therefore the defining characteristic of the product. That's why we use carefully selected, top-quality LiFePO4 cells from the brand-name manufacturer EVE in every one of our batteries, and we provide a detailed test report for each individual cell. With us, you can rely on us to deliver only high-quality, new, industrial-grade products – and you can even verify this yourself.
But for us, it's not just about which cells are used, but also about ensuring their quality remains transparent for our customers. While the components used in many battery systems are not visible and vary depending on the supplier, we prioritize openness in our high-quality complete batteries. Cell type, specifications, and quality are clearly defined and verifiable for you using the included test reports. This ensures flawless operation for decades. You know exactly what's working inside your battery and can personally verify its high-quality condition. Your advantages:
The battery is compatible with many commercially available 48V/51.2V inverters, including inverters from brands such as Victron, Deye, SMA, Growatt, Phocos, Lumentree, and similar manufacturers. A comprehensive list of compatible inverters can be found at: List of compatible inverters
The battery can communicate with inverters via its integrated CAN or RS485 interfaces. For correct communication, the battery's data protocol must be configured for the inverter manufacturer. By default, it is configured for data communication with Victron inverters. If you are not using a Victron inverter, please inform us of your inverter type immediately after placing your order so that we can configure the battery for communication with your inverter.
Communication between the battery and the inverter is via standard network cables. Data bus adapters are required for communication with Victron and SMA inverters; these can also be purchased from us.
Victron: Data bus adapter
SMA: Data bus adapter
Data communication is not strictly necessary for the operation of the battery.
The battery can generally be used without data communication. Communication is not strictly necessary for the battery to operate. However, the integrated communication module allows you to easily establish a data connection to your inverter.
As an alternative to integrated data communication, there is also the option of an external measuring hunt, which accurately records the state of charge and transmits it to your inverter.
Battery quality is something you shouldn't leave to chance.

The battery is maintenance-free. No refilling required – simply install and use.
All battery components are securely screwed together and deliberately not welded. This ensures easy repairs with standard tools, even many years from now. Each component can be removed and replaced individually. Furthermore, because it is a low-voltage battery (24-48V), there is no risk of electric shock, unlike with high-voltage batteries (200-1000V).
The two large screw terminals on the front make the battery particularly easy to connect while still allowing for high power delivery. You only need standard cable lugs. We deliberately avoid using manufacturer-specific connectors.
✔ The connector fits all standard cable lugs (recommended size: M8).
✔ The large contact area allows for the easy transmission of high currents.
✔ No expensive and manufacturer-dependent special plug is required.
You will receive a fully assembled and ready-to-use high-quality complete battery.
