Energy Storage Power Supply

The energy storage power supply is a series product developed for micro businesses and client groups with low load power. According to the power required by the clients, we may choose energy storage power supply of 10kW/20kWh, 20kW/40kWh or 30kW/60kWh; The power supply can be adjusted and the number of connected units can be added according to the load of the client, with no need for replacing the energy storage power supply, and it supports on/off-grid operation, to meet the requirements for dynamic capacity expansion, peak cut, off-grid power supply and other application scenarios.
