Nebula 630kW PCS

In energy storage systems, a PCS AC-DC inverter is a device connected between the storage battery system and the grid to facilitate the bi-directional conversion of electrical energy, serving as the essential component in the energy storage system. Our PCS is able to regulate the charging and discharging process of the energy storage battery, and can provide power to AC loads in the absence of the grid.
The 630kW PCS AC-DC Inverter can be applied to the power generation,transmission and distribution side and user side of the power storage system.It is mainly utilized in renewable energy stations such as wind and solar power stations, transmission and distribution stations, industrial and commercial energy storage, distributed micro-grid energy storage, PV-based electric vehicle charging stations, etc.
