BWS-RESS500K-1106M
Brightway Solar

The 500KW/1.106Wh outdoor 40-foot container ESS is designed for large-scale commercial and industrial energy storage projects. On the DC side, the system comprises eight modular lithium battery energy units, each with a capacity of 138kWh. While on the AC side, it utilizes the Brightway Solar series PCS. Through the EMS operation strategy, it interacts with the grid in a grid-friendly manner and provides power support for customers during periods of limited power supply.
