Power Conversion Systems (PCS) inverter are a crucial part of any energy storage system ESS. They help maximise the availability, value and performance of large or small energy storage systems. Our LB series 500K~630K battery pcs inverter is a battery power conversion system that converts the DC (direct current) supplied by a battery into grid-compliant AC (alternating current). This kind of energy storage pcs inverter can be used in the on-grid mode and off-grid mode.
