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.

What to do if my Goodwe GW15K-ET Inverter shows Utility Loss?
- J
  justinedwardsAug 25, 2025
  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.

What does Grid Frequency Instability mean on Goodwe GW15K-ET Inverter?
- S
  Sarah RussellSep 12, 2025
  A 'Grid Frequency Instability' error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency change rate does not meet the requirement of the local grid standard. If the problem occurs occasionally, the utility grid may be abnormal temporarily, and the inverter will recover automatically after detecting that the utility grid is normal. If the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it exceeds the permissible range.

What to do if Goodwe GW15K-ET shows Parallel IO check fail?
- K
  Katherine HamiltonSep 6, 2025
  If your Goodwe Inverter displays Parallel IO check fail, it indicates a communication error between parallel inverters. Check whether the parallel communication cable is connected correctly and firmly.

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.

What causes PV Input Overvoltage on Goodwe GW15K-ET?
- B
  Bradley BrownSep 12, 2025
  A 'PV Input Overvoltage' error on your Goodwe Inverter indicates that the PV array configuration is not correct, meaning too many PV panels are connected in series in the PV string. You should check the serial connection of the PV array to ensure that the open circuit voltage of the PV string is not higher than the maximum operating voltage of the inverter.
