The phosphate (LiFePO4) battery module is specifically designed for high-capacity and high-performance residential, commercial, and utility-scale energy storage systems. These ESS battery modules can be placed parallel for energy storage systems up to 81.92 kWh of total capacity. The ESS will integrate with any inverter or solar charge controller.
Longer Cycle Life: Offers a significantly longer cycle life and longer float/calendar life than lead-acid batteries helping to minimize replacement cost and reduce the total cost of ownership. LiFePO4 batteries are designed for 10,000 cycles at 50% DOD, 6,000 cycles at 80% DOD, and 2,000 cycles at 95% DOD.
More Energy: Delivers significantly more energy than lead-acid batteries, even at a high discharge rate while maintaining high energy capacity.
Advanced BMS Protection: Under/Over voltage and current protection ensure safe and efficient operation.
Safety: Advanced LiFePO4 cell design includes various safeguards including high temp thermal fuse and flame retardant additive.
Increased Flexibility: This LiFePO4 battery module is designed to be connected in parallel for applications up to 81.92 kWh. The modules are fitted into a cabinet for ground mount configuration with simple installation.
Protective Weatherproof Cabinet: Designed with a secure key lockable door with UV protective glass.
Clear Visual Display: LCD display showing voltage, current, SOC and temperature for each individual module.
