1stess 51.2V 300Ah 15.36kWh LiFePO4 Home Energy Storage Battery

The 1stess 51.2V 300Ah LiFePO4 battery delivers 15.36kWh of rated energy for residential solar energy storage and inverter-based home backup. This floor-standing home battery features a front touchscreen, a wheeled cabinet and RS485/CAN communication, making it suitable for solar EPC contractors, system integrators, battery importers and professional installers.

The specified output voltage range is 43.2–58.4V, charging voltage is 57.6–58.4V and cut-off voltage is 43.2V. Maximum discharge current is 150A. Confirm the selected inverter's battery voltage range, communication protocol and current limits before integration. An external inverter is required for AC loads.

An integrated battery management system provides overcharge, over-discharge and short-circuit protection. The cycle-life reference exceeds 6,000 cycles at 0.2C, 25°C and 80% DOD; actual results depend on operating conditions. The front display supports local battery-status checks, while side access and caster wheels assist equipment inspection and positioning.
