Low voltage storage battery Felicity FLA48171-EU 8.75kWh LiFePO4 wall or floor mounted
The Felicity FLA48171-EU is an 8.75kWh LiFePO4 storage battery at 51.2V nominal, sized for a household consuming 15 to 25kWh a day that wants to cover evening and night with a single module. It accepts up to 120A of continuous current and 6000W of charge/discharge power, so it comfortably backs a 5-6kW single-phase hybrid inverter.
It mounts on the wall or on the floor and integrates WiFi, Bluetooth, CAN and RS485 for remote monitoring and inverter dialogue. A smart BMS with breaker and fuse plus an aerosol fire suppression system take care of safety, while scalability up to 15 units in parallel (131.5kWh) lets you start with one module and grow over time. ≥95% DOD and ≥6000 cycles.
