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.

Frequently Asked Questions

How much storage does the FLA48280 provide?

14.3 kWh of nominal energy, from 280 Ah at 51.2 V nominal. The depth-of-discharge row is separate, specified above 95%, and it is what governs how much of that nominal energy is drawn.

Can the FLA48280 be wall-mounted?

135 kg is the unit weight, and floor-mounted is the installation this record specifies; packed for transport it is 160 kg in a 635 x 498 x 1150 mm carton.

How large a bank can the FLA48280 build?

215 kWh, from up to 15 units in parallel on a single 51.2 V bus.

What are the current and power limits of the FLA48280?

150 A of continuous charge and discharge, with 120 A recommended, plus a separate 15-second ceiling of 200 A and 7,500 W. Warranty is 7 Years.
