The 215 commercial & industrial energy storage system adopts the all-in-one design concept. The cabinet is integrated with a battery management system (BMS), energy management system (EMS), modular power conversion system (PCS), and fire protection system. The system's capacity is up to 215 kWh and the power is up to 100 kW. The modular design allows for flexible expansion, adapting to various scenarios such as power expansion, backup power supply, and black start (the ability to restore power without relying on the help of other networks after the power system is out of service due to a fault).

A commercial energy storage system works by storing excess energy generated by solar panels during the day. This stored energy can then be used at night or during cloudy weather. The power conditioning system (PCS) converts direct current (DC) electricity into alternating current (AC) electricity. The isolation transformer ensures safety and grid compliance, while the MCB connects the system to the grid and the load.
