The EG4 PowerPro is a 48 V, 280 Ah LiFePO4 wall-mount battery rated at 14.3 kWh, built for whole-home and light commercial storage. Its IP65 all-weather casing and UL1973 listing let it go outdoors where most indoor-only server-rack batteries cannot. It delivers 10 kW of output and works with EG4, Growatt, Sol-Ark and Victron inverters. At about 309 lbs it is a two-person or equipment install, and its capacity and sealed housing put it ahead of smaller indoor rack batteries for outdoor backup.
