Solves: Large loads that currently depend on a generator
Roxon BESS Pro 270–540 kW
The Roxon BESS Pro 270, 405 and 540 kW (RP270, RP405, RP540) are high-power storage systems with blade-type LFP cells, of 220, 440 and 660 kWh at 832 V. They recharge at 1C in 0.81 to 1.22 hours, charge and discharge at the same time, and have aerosol suppression, an IP67 battery and an IP55+ system.

Application · Industry and remote operations
Energy for operating away from the grid.
A generator sized for peak demand spends much of its time at low load, especially at night. During those hours it burns fuel and adds maintenance to supply small loads, and hauling the fuel adds cost and logistics.
Used in: Industry and remote operations
