Revolta Installs First 10 kWh Sodium-Ion Home Battery in Germany
Revolta has installed and commissioned its first 10 kWh sodium-ion home battery system at a customer's property in Germany. This high-voltage system operates at 450 V and comprises five 2 kWh battery modules. The installation supports the customer's goal of greater energy independence, complementing existing solar PV and hydroelectric power.
Revolta, a Frankfurt-based company, has successfully installed and commissioned its inaugural sodium-ion home battery system. This installation took place at a customer's property near Aschaffenburg, Germany, marking a significant step in the deployment of this technology.
The deployed system is a high-voltage solution, operating at a nominal voltage of 450 V. It incorporates five individual battery modules, collectively providing a total capacity of 10 kWh. Each module offers 2 kWh of capacity, weighs 18.7 kg, and features an IP64 protection rating. An SMA inverter is utilized for energy conversion.
The customer's property already benefits from approximately 20 kW of solar PV and a small hydroelectric plant, which has been supplying the family with electricity since 2017. The owner expressed a specific desire for a suitable sodium-ion home battery to further enhance their energy independence. The batteries can be charged and discharged at 0.4 C, equating to a 2.5-hour power duration. For this 10 kWh configuration, a maximum power output of 4 kW can be anticipated.
The energy density of the modules is reported at 141 Wh/l and 107 Wh/kg. Revolta plans to conduct further installations at selected customer sites across Germany in the coming weeks. These pilot customers will receive additional measuring devices to collect operational data. The findings from this data collection will inform the ongoing development of Revolta's battery management system and firmware.
While Revolta describes this installation as the commencement of its commercial launch, the rollout remains in a pilot stage. The company has indicated that its 2026 production is already sold out, but reservations for 2027 are available. The list price for a 2 kWh module is €599, making the total for the 10 kWh installation €2,995.
