The EG4 PowerPro is a 14.3kWh wall-mounted LiFePO4 battery built for whole-home backup and off-grid systems. It delivers 10kW continuous output with short surges to 15.4kW, and its IP65 enclosure and integrated self-heating let it sit outdoors in cold or wet conditions. UL 9540A and UL 1973 listings put it in the same class as the server-rack and wall batteries it competes with, but it stores more energy per unit than most 48V rack batteries and mounts on a wall instead of in a rack. Owners rate it highly for capacity and build; the main trade-offs are its 308 lb weight and a 140A continuous discharge limit that caps how large an inverter it can feed on its own.

Owners rate it 4.8 out of 5 and praise the capacity, the outdoor-rated enclosure and the cold-weather heating. Complaints center on the weight and the effort of hanging it.
