FAQ

01 How much energy can the Callsun 14.34kWh LiFePO4 battery store?

The Callsun 51.2V 280Ah LiFePO4 battery provides 14.34kWh of nominal energy storage. It is suitable for residential solar systems, off-grid applications, and home backup power. The actual usable energy depends on the battery's operating limits, inverter efficiency, and connected loads.

02 Is this 51.2V 280Ah battery compatible with my solar inverter?

This battery is designed for compatible 48V-class inverter systems. Before purchasing, check your inverter's supported battery voltage range, charging parameters, maximum charge and discharge current, and BMS communication requirements to ensure compatibility.

03 How long can this 14.34kWh battery power my home during a power outage?

Backup runtime depends on your energy consumption and system efficiency. For example, assuming 90% usable energy after system losses, this battery could power a 500W load for approximately 25.8 hours or a 1,000W load for approximately 12.9 hours. Actual runtime varies with operating conditions and battery settings.

04 Can I connect multiple batteries to increase my energy storage capacity?

Multiple batteries may be connected in parallel if the battery model supports expansion. Adding compatible batteries can increase total storage capacity for larger residential or off-grid systems. Check the manufacturer's limits for the number of batteries, wiring configuration, BMS communication, and inverter compatibility before expanding your system.

05 Can I use this battery with solar panels for whole-home backup?

Yes. When paired with a compatible hybrid inverter and properly sized solar array, this battery can store solar energy for household use and provide backup power during grid outages. The amount of your home that can be powered depends on the inverter's output capacity, battery discharge limits, and the total demand of your appliances.
