The FLA24300WG2 is Felicity Solar's 7.5kWh LiFePO4 battery, a 25.6V nominal pack that sustains 4480W of continuous charge or discharge, absorbs a 300A peak current and is rated for ≥ 6000 Cycles, with a depth of discharge of ≥95%. The cabinet weighs 64 kg and measures 400 x 269 x 475 mm. Behind the panel, BMS version S515 supervises the cells with a built-in smart BMS and a fuse, holding a 24V cut-off voltage, a 28.8V floating charging voltage and a 28.8V maximum charging voltage inside a 22.4-28.8V operating window, while an LCD+LED display reports the pack state on the spot. CAN and RS485 carry that data to a compatible inverter. Fifteen of these cabinets gang in parallel for 112.5kWh at a maximum charging current of 175A*N, or 100A of continuous current each. Shipping cartons measure 512x547×343mm. Charging runs 0-55°C, discharging -20-55°C, working -20°C to +55°C and storage 0°C to +35°C, with 5% to 95% humidity and ≤2000m of elevation. Certifications are UN38.3, CE-EMC and IEC 62619. We are the authorised Felicity Solar distributor for this 7.5kWh model and supply it with a warranty of 2 Years.
