Felicity FLA48280-EU 14.3kWh LiFePO4 Low-Voltage Storage Battery, floor standing
The FLA48280-EU is the floor standing version of the FLA range, the one most often fitted because it works at 51.2V and therefore gets along with any low-voltage hybrid inverter. 14.3kWh in a single unit means one installation, one set of cables, one BMS to configure.
The cells are 280Ah LiFePO4 and the maker states over eight thousand cycles: at one cycle a day that is more than twenty years before falling to eighty per cent of capacity. The built-in BMS measures every cell, balances and protects against overcharge, deep discharge and out-of-range temperature.
It talks CAN and RS485 to the common hybrid inverters and sits alongside further units when more autonomy is needed. Ten-year manufacturer warranty. We ship within Italy and across the European Union.
