Videos & Customer Installation Feedback
FAQ
Is this a 20kWh LiFePO4 pack?
Yes. Nameplate energy is 20.48kWh with LiFePO4 chemistry.
Is the voltage 48V or 51.2V?
Nominal voltage is 51.2V DC for 48V-class low-voltage inverter systems, with a 44–57.6V operating range.
What capacity and communication does it use?
Rated capacity is 400Ah. Communication includes CAN / RS485 / Bluetooth / WiFi.
How should backup runtime be estimated?
Use 20.48kWh ÷ connected load as a nominal battery-side estimate, then confirm inverter limits and load schedule.
What loads can it support?
Selected home and light commercial loads when inverter size, startup current and total power stay within system limits.
Can it work with my inverter?
It works with compatible low-voltage hybrid inverters that support 51.2V platforms, the 44–57.6V range and matching communication.
Can the system be expanded?
Yes. Parallel support is up to 18 units, subject to inverter and system design.
Who should choose this 20kWh battery?
Choose it for home backup or light commercial storage when you need more capacity than a small wall pack, with matched inverter voltage and communication.
What should buyers send before quotation?
Send the load list, inverter model, site voltage, backup target, installation location and required quantity.
