PCS Working Principle
Charging Mode (AC to DC): During the day, when the power generated by the photovoltaic arrays (PV1~PVn) through the PV inverters (INT1~INT2) is abundant and exceeds the demand of the building load on the right, there will be surplus electrical energy on the AC bus. At this time, the EMS will command the PCS to enter the rectification/charging state. The PCS converts the alternating current from the AC bus into direct current and stores it in the batteries (BAT1~BATn) below.
Discharging Mode (DC to AC): At night, during periods of insufficient sunlight, or during peak power consumption when PV generation cannot meet the load demand, the system needs supplementary energy. At this point, the PCS will enter the inversion/discharging state. It converts the direct current stored in the batteries (BAT1~BATn) into alternating current and delivers it to the AC bus, working in coordination with the PV system, the high-voltage grid (High AC), or the diesel generator (DG1) to supply power to the load.
