The F5 series is a floor-standing, modular low-voltage all-in-one energy storage system that integrates a safe LiFePO4 battery stack with a built-in 5 kW single-phase inverter and a dedicated PV input. Offered in four flexible capacities — 5.22, 10.44, 15.66 and 20.88 kWh — it delivers efficient, flexible energy storage and backup for home PV systems or small commercial stores. It supports remote smart management, sub-second grid/off-grid switchover within 20 ms, and is protected by high/under-voltage, short-circuit and overload protection with CAN/RS485 communication.
