    Why I am unable to log in to the parallel system interface in APP for Goodwe GW15K-ET?
    • J
      Juan GuerraSep 6, 2025
      If you are unable to log in to the parallel system interface in the APP with your Goodwe Inverter, it could be due to a parallel networking failure, often caused by an incorrect or unreliable communication cable connection. Connect the smart meter and Ezlink module to the same master inverter to ensure the success rate of networking. Check whether the inverter communication indicator is normal. If it is not, please check the individual inverter according to its own troubleshooting method. If the above methods cannot solve the problem, please try to restart the inverter and get networking again.

      If your Goodwe Inverter shows a Utility Loss, it could be due to a failure in the utility grid power. The alarm should automatically clear once the grid power is restored. Another cause might be a disconnected AC cable or an AC breaker that is off. Ensure the AC cable is properly connected and the AC breaker is switched on.

    Why does my Goodwe GW15K-ET show Grid Overvoltage?
    • R
      Rachel GriffithAug 26, 2025
      If your Goodwe Inverter is showing a Grid Overvoltage error, it could be because the grid voltage exceeds the acceptable range, or the duration of high voltage surpasses HVRT requirements. If this happens occasionally, it may be a temporary issue with the utility grid, and the inverter should automatically recover once the grid voltage returns to normal. If the problem occurs frequently, verify that the grid voltage is within the permissible range. If it's not, contact your local power company. Also, ensure the AC breaker and output cables are securely and correctly connected.

    How do I troubleshoot an Abnormal Ground error on my Goodwe Inverter?
    • L
      Larry AshleySep 10, 2025
      An 'Abnormal Ground' error on your Goodwe Inverter can be caused by: 1. The PE cable of the inverter not being well connected. 2. The L cable and N cable being connected reversely when the output of the PV string is grounded. Check whether the PE cable of the inverter is properly connected. Also, check whether the L cable and N cable are connected reversely if the output of the PV string is grounded.

    What does Large DC of AC current L1 mean on Goodwe GW15K-ET?
    • S
      Stephanie ChungSep 2, 2025
      If your Goodwe Inverter shows Large DC of AC current L1, it means that the DC component of the output current exceeds the safety or default range. If the problem is caused by an external fault like a utility grid exception or frequency exception, the inverter will recover automatically after solving the problem.

    How to fix low insulation resistance on Goodwe Inverter?
    • H
      henry68Sep 18, 2025
      If the Goodwe Inverter indicates low insulation resistance, it's likely that the input insulation impedance has become low during operation. To resolve this, check the impedance between the PV string and PE to ensure it is not too low. If the problem persists, further inspection may be needed.

    How to resolve PV Input Overvoltage on Goodwe Inverter?
    • M
      Marc HamiltonAug 28, 2025
      If your Goodwe Inverter is showing PV Input Overvoltage, it means the PV array configuration is incorrect, and too many PV panels are connected in series in the PV string. Check the serial connection of the PV array. Ensure that the open circuit voltage of the PV string is not higher than the maximum operating voltage of the inverter.
