The Power Conversion System (PCS) efficiently connects battery banks to the grid or loads, enabling bidirectional energy conversion. It converts DC from batteries to AC for grid or load use and AC from the grid to DC for battery charging. Equipped with a DC/AC bidirectional converter and control unit, the PCS regulates active and reactive power based on backend commands. It communicates with the Battery Management System (BMS) via CAN interface, ensuring safe and protective charging and discharging, thereby enhancing overall system reliability and safety.
