About the Felicity Solar FLA48280 51.2V 14.3kWh LiFePO4 Battery

The Felicity Solar FLA48280 is a floor-mounted 51.2 V LiFePO4 battery rated 280 Ah and 14.3 kWh of nominal energy, sustaining 150 A of continuous charge and discharge current at a recommended 120 A, and paralleling to 15 units for a 215 kWh maximum system capacity. Warranty is 7 Years. Depth of discharge sits on its own row above 95%, so the 14.3 kWh is a nominal rating and not the energy released per cycle; rated life is 6,000 cycles. A 15-second ceiling of 200 A and 7,500 W is quoted apart from the continuous figure. Voltage runs 44.8 V to 57.6 V, cutting off at 44.8 V. Protection is a built-in Smart BMS with a breaker and a fuse, CAN and RS485 carry pack data, and an LCD reports at the cabinet. The unit weighs 135 kg and stands on the floor rather than a wall; packed it is 160 kg in a 635 x 498 x 1150 mm carton. It is rated IP21, stores at 0-35 °C, tolerates 5-95% humidity and works below 2000 m. We are an authorised Felicity Solar distributor and supply the FLA48280 from our own stock.
