The LGNE 522 kWh Mobile Energy Storage System is a transportable, high-capacity power solution designed for construction sites, temporary charging stations, equipment rental operations and locations with limited grid capacity.
The system integrates a 522 kWh LFP battery, high-power DC charging, bidirectional AC power conversion, thermal management, fire protection and intelligent system control within a compact enclosure. It supports up to 320 kW total DC charging output and 250 kW bidirectional AC power, enabling both rapid charging of electric equipment and temporary AC power supply.
With two independent DC charging outputs, a 400 V / 630 A bidirectional AC interface and a 230 V auxiliary output, the system can support electric excavators, loaders and other off-highway equipment. Charging interfaces, AC connections and power configurations can be adapted according to project requirements.
