Benefits & Tips

  • Reliable home energy storage with a built-in BMS and CAN RS485 for easy monitoring and system integration.
  • Use the active balance switch after about six months of operation to restore voltage balance; cycle the battery a few times, then disable the switch when balance is achieved. Note: enabling the active balance may affect available capacity.
  • Take advantage of the fire protection device for enhanced safety in high-temperature scenarios; the device will engage if temperatures reach 180°C, releasing fire extinguishing material as a precaution.
