Felicity Solar Lithium Batteries FLA48300

Wall- or floor-mounted at 135 kg, the FLA48300 puts 300 Ah and 15 kWh on a 51.2 V bus and stacks to 15 units for 225 kWh.

Models Covered: FLA48300

Manufacturer: Felicity Solar

Application: The Felicity Solar FLA48300 is a 51.2 V LiFePO4 battery rated 300 Ah and 15 kWh of nominal energy, sustaining 150 A of continuous charge and discharge current at a recommended 120 A, with a 15-second ceiling of 200 A and 10,000 W, and paralleling to 15 units for a 225 kWh maximum system capacity. Warranty is 7 Years. The 15 kWh is nominal energy; the depth-of-discharge row stands apart at ≥95%, and rated life is 6,000 cycles. Voltage runs from a 44.8 V cut-off to a 57.6 V charging ceiling. Protection combines a built-in Smart BMS, a breaker and a fuse, CAN and RS485 hand pack data to a compatible inverter, and an LCD reports locally. The cabinet weighs 135 kg and takes either a wall or a floor; packed it is 160 kg in a 635 x 498 x 1150 mm carton, and that packed figure is the one to plan handling around. It is rated IP21, charges from 0 to 55 °C, discharges from -20 to 55 °C, stores at 0-35 °C, tolerates 5-95% humidity and operates below 2000 m. We are an authorised Felicity Solar distributor and supply the FLA48300 from our own stock.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions

How much energy does the FLA48300 store?

15 kWh of nominal energy, from 300 Ah at 51.2 V nominal, with depth of discharge rated separately at ≥95%. The two are read side by side, not merged into a single usable number.

How big a bank can FLA48300 units form?

225 kWh, from up to 15 units paralleled on a single 51.2 V bus.

What are the FLA48300 current ratings?

150 A of continuous charge and discharge, 120 A recommended, and 200 A with 10,000 W over a separate 15-second window.

How is the FLA48300 installed and what does it weigh?

135 kg for the unit and 160 kg once packed into a 635 x 498 x 1150 mm carton; it mounts on a wall or on the floor. Warranty is 7 Years.
