Frequently Asked Questions

How much energy does the FLA48350TG2 store?

17.5kWh is the nominal energy, from a 350Ah string at 51.2V. How much of it you can draw is governed by a separate row, depth of discharge, rated at 95% or better — the 17.5kWh figure itself is nominal, not usable.

What current and power can the FLA48350TG2 handle?

175A of continuous charge and discharge current, with a 300A peak and 8750W for 15 seconds. Cut-off voltage is 44.8V, maximum charging voltage is 57.6V, and the operating window runs 44.8-57.6V.

How many FLA48350TG2 units can run in parallel?

15 units, giving a maximum system capacity of 262.5kWh. CAN and RS485 ports carry the data between the units and a compatible inverter.

How long is the FLA48350TG2 rated to last, and what warranty does it carry?

8000 cycles is the rated cycle life and the warranty term is 5 Years. The cabinet is rated IP21, charges from 0 to 55 °C and discharges from -20 to 55 °C.
