Volt-EM261 is a 261kWh air-cooled LiFePO4 battery system with an external hybrid-inverter arrangement for commercial energy storage projects.
Industrial park
Villa residence
Farm
Power station
Volt-EM261 pairs a 261kWh battery cabinet with the selected hybrid inverter. This arrangement supports project planning for industrial parks, farms and other commercial sites where energy storage must be coordinated with existing generation and loads.
