Central inverter

Clou Central inverter can realize bi-directional energy of transmitting between DC battery and AC grid and play the role of recharging and electricity feedback. By control strategy, it can manage the battery charge and discharge, the load tracking of power grid side, charge and discharge control of battery energy storage system and the grid voltage control in normal and islanding operation condition and so on. The power ranges from 10 kWh to 500 kWh, our ESS has widely applied in residential ESS and commercial ESS.
