Industrial and commercial ESS -261kWh(Liquid Cooling)

The energy storage system is an industrial
and commercial distributed energy storage
power supply, the system uses intelligent
software for automatic calculation of power
generation and consumption, and the
excess power will be automatically
deposited into the lithium-ion battery
pack, the system has high capacity,
long life and high safety.
