50KW-100KW Lithium Motor Cabinet Solar Energy Storage System For Domestic Industrial Use
The lithium motor cabinet energy storage system consists of high-performance lithium battery, BMS battery management system, photovoltaic charging device, inverter device, and corresponding combination to form a multi-capacity, power, functional energy storage system.
The cabinet type energy storage system can be directly connected to the photovoltaic solar panels, and the generated energy can be stored in the battery, or inverted for load use.
At night or when the sunshine is not so strong, the ESS will provide power for loading equipment automatically.
As a control and energy center, a micro-grid will be established in power-free areas to provide reliable and sustained electricity for users.
