    8 Troubleshooting DO NOT try to repair or maintain the inverter by yourself; it may cause danger. WARNING Phenomenon Possible reasons Troubleshooting Green indicator slowly Suppose the DC input voltage goes lower DC input voltage under flashing than10.8/21.6/43.2V. Adjust the input voltage Buzzer sounds voltage to restore normally.

  • Page 33: Maintenance

    9 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for good performance.  Make sure no block on airflow around the inverter. Clear up any dirt and fragments on the heat sink.  Check all the naked wires to ensure insulation is not damaged by sun exposure, frictional wear, dryness, insects or rats, etc.
