Battery Cell & BMS

LiFePO4 (LFP) cells paired with an intelligent battery management system. The BMS tracks system voltage, current, cell voltage, cell temperature and module temperature, calculates SOC with an intelligent algorithm, and draws below 2W in operation (below 100mW in sleep). Communication to the inverter runs over CAN/RS-485.

Key Advantages

As the largest capacity of the home battery line, one 280Ah unit stores 12902Wh of usable energy — enough coverage for evening and overnight loads in larger homes. More than 6000 cycles at 80%DOD and a 10+ year design life keep the cost per stored kWh low.

Applications

Home solar energy storage for higher self-consumption, backup power during outages and lower electricity bills — sized for larger households with overnight air conditioning, heat pumps or EV charging at home.

Frequently Asked Questions

How long does the battery last?

The battery is rated for more than 6000 cycles at 25℃±2℃ with 80%DOD and a design life of over 10 years, backed by a 5-year product warranty.

Is it compatible with my hybrid inverter?

The battery communicates over CAN/RS-485 and works with mainstream hybrid inverters. Confirm the communication protocol with your installer before ordering.

How much of the capacity is usable?

Of the 14336Wh nominal capacity, 12902Wh is usable. The smart BMS protects the cells and reports voltage, current and temperature in real time.

What charge and discharge currents does it support?

The recommended charge/discharge current is 140A with a 200A maximum, so the battery can follow fast charge and discharge demands from the hybrid inverter.
