Compatibility

The Felicity FLA48300TG2 is designed for 48V-class inverter systems that support 51.2V LiFePO₄ batteries. It supports RS485/CAN communication, but inverter communication compatibility should be confirmed with the specific inverter brand and model before installation.

Felicity states that the battery is compatible with leading inverter brands. Where direct BMS communication is not available, some inverter systems may still allow user-defined lithium battery settings, depending on the inverter.

Best For

The Felicity FLA48300TG2 is best for homes, offices, shops, clinics, small businesses and larger solar backup systems that need long backup time from a high-capacity lithium battery. It is suitable for essential and moderate loads such as lights, TVs, fridges, routers, CCTV, computers, office equipment and other appliances when connected to a properly sized inverter system.

What to Consider Before Buying the Felicity FLA48300TG2 15kWh 51.2V Lithium Battery

• This is a battery only. It does not include an inverter or solar panels.
• Confirm that your inverter supports 51.2V / 48V-class lithium batteries.
• For lithium communication, confirm RS485/CAN compatibility with your inverter brand and model.
• The battery weighs 118.5kg, so delivery, positioning and installation space should be planned properly.
• Battery backup time depends on your connected appliances and total power consumption.
• For larger systems, it can be expanded up to 15 units in parallel with compatible installation design.
• The IP21 rating means it should be installed indoors or in a protected equipment room.
• Use a qualified solar technician for installation, inverter configuration, battery protection and system testing.
