Low voltage storage battery Felicity FLA48100UG1 5.12 kWh LiFePO4 wall, rack or stackable
The Felicity FLA48100UG1 is a 51.2 V / 100 Ah LiFePO4 storage module rated 5.12 kWh, designed for residential PV systems built around 48 V low-voltage inverters. It stores energy from the solar array or the grid and feeds household loads whenever needed, including during a blackout.
What sets it apart is installation freedom: the very same module can be wall-mounted, stacked with other modules or slotted into a rack. A smart BMS with built-in breaker and fuse, an on-board aerosol fire extinguisher and CAN and RS485 communication make it suitable both as a single pack and in systems of up to 163.84 kWh with 32 units in parallel. IP21 protection for indoor use and a 7-year warranty.
