Recommended Applications of Energy Cube 125kW/261kWh
This 125kW/261kWh BESS energy cube is an ideal energy storage solution for C&I applications. It features built-in PCS, EMS, and BMS systems. The PCS ensures the bidirectional conversion between DC and AC power, converting DC energy from the BESS to AC power for loads. Working together with the EMS and BMS, it guarantees reliable power supply for industrial peak shaving and valley filling needs.
During peak hours, the system can discharge to reduce dependency on the grid, while it charges during off-peak periods using low-cost electricity. In this way, it helps lower operating costs and provides a stable and efficient power supply for industrial park owners.
