Felicity FLA48314-EU

Felicity FLA48314-EU is a battery cabinet which stands on the floor and collects the energy produced by the panels, so that you can use it when there is no more sun. The difference from the smaller models lies in the power: it can take in and give out energy quickly, not just in large amounts. It has its own electronic protection, fuses and an extinguisher which acts automatically, and its state can be seen on the phone.

16 kWh indicatively covers a day's consumption for a family home, including winter evenings. The 160 A continuous, that is 8 kW in both directions, means that the battery can charge quickly when there is plenty of sun and can supply heavy loads at the same time; the peak of 300 A, for 15 seconds, covers the starting of motors. 95% of the energy is used, and the declared service life exceeds 8000 cycles, indicatively more than 20 years at one cycle a day. The unit is mounted on the floor, with fixing brackets included, so it needs a flat surface and space in front for access. Monitoring and diagnosis are done from the Fsolar app, over WiFi or Bluetooth.

LiFePO4, 51.2 V nominal, range 44.8-57.6 V, 314 Ah, 16 kWh; maximum continuous current 160 A on charge and 160 A on discharge (8 kW in each direction), peak 300 A / 15 s, DoD 95%. Declared service life more than 8000 cycles under standard conditions (25 degrees C, 0.5C/0.5C, 90% DoD, 70% EOL). Protection through an intelligent BMS, a breaker and a replaceable external fuse, plus an integrated aerosol extinguishing system. RS485 and CAN communication, built-in WiFi and Bluetooth for the Fsolar app; up to 15 units in parallel (240 kWh), 10-year warranty.

Who it suits

Suitable for a family house with high consumption and a three-phase inverter, which needs both capacity and high charging power during the sunny hours.

Terms explained

• 0.5C: A way of expressing the speed of charging or discharging: 0.5C means that the battery fills or empties in about two hours at that regime.
• Replaceable external fuse: A fuse mounted accessibly, outside the sealed part; if it blows, it is changed on the spot, without dismantling the battery.
• 300 A peak: The high current the battery can give for only 15 seconds, at the start-up of a pump, air conditioning or washing machine motor.

Technical specifications

Recommended applications

• Large residential storage, with one day of autonomy
• Three-phase hybrid systems for homes
• Small commercial applications with an extended battery bank

Warranty

10 years

Technical details

Specifications confirmed from the manufacturer's datasheet

Felicity FLA48314-EU is a 16 kWh LiFePO4 battery built on 314 Ah cells, with a nominal voltage of 51.2 V and an operating range of 44.8-57.6 V. The maximum continuous charge and discharge current is 160 A, the equivalent of a power of 8 kW in each direction, with a peak of 300 A for 15 seconds. The depth of discharge is 95%, and the declared service life exceeds 8000 cycles (25 degrees C, 0.5C/0.5C, 90% DoD, 70% EOL).

The unit is built for floor mounting, with fixing brackets included. The protection is provided by an intelligent BMS, a breaker and a replaceable external fuse, plus an integrated aerosol extinguishing system. Communication towards the inverter is done through RS485 and CAN, and the built-in WiFi and Bluetooth modules allow monitoring and diagnosis through the Fsolar app. Up to 15 units can be connected in parallel, for a total of 240 kWh.
