About the Felicity Solar FLS48050SG1M4 51.2V 2.56kWh LiFePO4 Battery

The Felicity Solar FLS48050SG1M4 is a floor-mounted LiFePO4 battery with a module nominal voltage of 51.2V, a module nominal energy of 2.56kWh and a module nominal capacity of 50Ah. It weighs 124.0 kg net and 148.0 kg gross, and it is rated for more than 6000 cycles, with depth of discharge rated separately at ≥95%. The system operating voltage runs from 44.8V to 57.6V, so a connected inverter sees a defined window between full charge and cut-off. Charging is specified from 0°C to 55 °C and discharging from -20°C to 55 °C, with storage held between 0°C and +35°C and installation below 2000m altitude. The battery designation recorded for this unit reads 150/102/[1P16S]M/-10+50/95. Because 124.0 kg net and 148.0 kg gross is the figure that sets the FLS48050SG1M4 apart, confirm the delivery route, the lifting arrangement and the floor loading before the unit arrives. Recorded certifications are CE-EMC and IEC 62619, and the warranty term is 5 Years. We are an authorised Felicity Solar distributor and supply the FLS48050SG1M4 from our own stock.
