BESS
BESS 50kW/51.2kWh
A cabinet-format battery energy storage system combining a 51.2 kWh LiFePO₄ battery (512 V nominal, 100 Ah) with a 50 kW three-phase high-voltage hybrid inverter. The 50 kW figure is the inverter's rated power; 51.2 kWh is the battery's stored energy.
Supplied on a quotation basis. Specifications as published by PowerStorm; confirm against the datasheet at the time of order.

50 kW is the inverter's rated power — how much load it can supply at once. 51.2 kWh is the battery's stored energy. They are different measurements and do not by themselves give a runtime.
Ah (100 Ah) is charge capacity at the nominal voltage; kWh (51.2 kWh) is stored energy, equal to 512 V × 100 Ah. Energy is what determines how long a load can run.
Published: CAN / RS485 / Modbus. Compatibility with a specific inverter or controller is not stated on the datasheet — ask us to confirm for your equipment.
The enclosure is rated IP54. Please follow the datasheet and installation guidance for the environment.
≥ 4000 cycles (25 °C, 0.5C charge/discharge, 70% end of life). Real-world life depends on operating conditions.
