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
A design life of over 10 years with more than 6000 charge/discharge cycles at 80%DOD gives the battery a long service life, while the 50kg slim wall-mounted housing keeps the footprint small. All-time monitoring by the smart BMS keeps every cell within its safe operating window.
Applications
Home solar energy storage for higher self-consumption, backup power during outages and lower electricity bills. The battery works as the DC storage side of a hybrid inverter system in houses, villas, apartments and small home offices.
