Before installing this 5kWh wall-mounted LiFePO4 battery, check wall load capacity and use the dedicated bracket for firm mounting. It needs to work with a compatible inverter with matched communication protocol. It covers many scenarios: residential solar storage, power outage backup, small shop emergency power supply and off-grid cabins. It is designed for indoor use and should be kept away from rain and moisture. Thanks to modular design, users can add more units later. One single 5kWh unit can support basic appliances like lights, refrigerators and routers for hours during outages.
