The 51.2V LiFePO4 battery is a core and preferred device for home solar energy storage systems with a standard 16-cell configuration, compatible with most household photovoltaic equipment. Adopting highly stable LiFePO4 material, it greatly reduces fire and explosion risks with better safety than traditional lead-acid batteries. Built-in intelligent BMS provides full protection against overcharging, overdischarging, overcurrent, short circuit and extreme temperatures. With a high protection level, it suits indoor and outdoor installation, operates stably and silently, and safeguards household clean energy storage all day long.
