Adopting a lightweight modular design, the 8KWh household LiFePO4 battery has a compact body and supports multiple installation methods such as wall mounting and floor placement without occupying household space. Equipped with an intelligent battery management system, it realizes real-time cloud monitoring of power level, operating status and fault information, as well as remote regulation and intelligent start-stop. With strong compatibility, it can be seamlessly matched with mainstream household photovoltaic inverters, on-grid and off-grid power supply systems. It requires simple operation and maintenance with automatic fault early warning and independently maintainable modules, greatly reducing the operation and maintenance difficulty and time cost of household energy storage equipment.
