An outdoor 40-foot container ESS with a capacity of 500KW/1.106Wh is designed for large-scale commercial and industrial energy storage projects. The DC side of the system comprises eight modular lithium battery energy units, each with a capacity of 138kWh. On the AC side, it employs an SNE hybrid inverter PCS, which, through the EMS operation strategy, interacts seamlessly with the grid and provides power backup to customers during periods of limited electricity supply.
