Description
The 44.8–57.6 V operating window matches the battery input of low-voltage inverters. Of the nominal 10.24 kWh, 9.728 kWh is usable. A 1C current, meaning 200 A or 10.24 kW, holds continuously, and the battery supplies a 300 A peak for 2 min, enough to start a pump or compressor. Up to 50 units form a 512 kWh system, the parallel bus runs through the units themselves, and no combiner box with its breakers is needed. The IP65 housing and operation at −20 °C permit placement in an unheated garage or outdoors under a canopy. The cells are LiFePO4, and each unit has an aerosol extinguisher and a pressure relief valve.
How to choose
Current drives the choice, since 200 A continuous and 300 A peak cover an inverter with roughly 10 kW of battery power. The previous PowerBox G2 generation has the same capacity with IP66 protection and heating, and it fits open sites with no canopy. When one unit needs more energy, look at the floor-standing PowerBrick batteries on wheels.
