PCS converter for battery energy storage in commercial and industrial application.
PCS power conversion system energy storage is a multi-functional AC-DC converter by offering both basic bidirectional power converters factions of PCS power and several optional modules which could offer on/off grid switch and renewable energy access. The 125kW/250kW PCS converter well fits the requirement of Battery Energy Storage in commercial and industrial applications.
Both Energy Storage PCS power conversion system and Lithium-ion Battery System are made by SCU in house. As a hybrid inverter supplier, we could support your PCS battery storage business from power generation, through transmission and distribution, and all the way to users.
125kW/250kW PCS module
The pcs power conversion system supports both grid connection mode, off grid mode (microgrid mode)
Optional STS module support to achive on grid/ off grid seamless transfer
Could take the place of generator and UPS
125kW/250kW module, flexible configuration, easy maintenance.
