Frequently Asked Questions

12.5 kWh of nominal energy, from a 250 Ah LiFePO4 pack at 51.2 V nominal. Depth of discharge is separately rated above 95%, so the 12.5 kWh figure is the nominal energy of the LPBF48250 and not a usable-energy rating.

Six. Up to six LPBF48250 units run in parallel, for a maximum system capacity of 75 kWh, and each unit contributes its own 12.5 kWh of nominal energy to that total.

120 A is the recommended charge and discharge current, equal to 6,000 W, and the pack peaks at 200 A and 10,000 W for 15 seconds. Operating voltage runs 48-57.6 V, with a 48 V cut-off and 57.6 V maximum charging voltage.

154 kg, floor-mounted, in a cabinet measuring 615 x 350 x 955 mm; the shipping carton is 718 x 450 x 1112 mm at 177 kg packed. The LPBF48250 is rated IP21, charges from 0 to 55 °C and discharges from -20 to 60 °C.
