What causes PV Continuous Software Overcurrent on a Goodwe GW15K-ET?
If your Goodwe Inverter displays PV Continuous Software Overcurrent, it could be caused by an improper PV configuration or hardware damage. Disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
How to fix String1 PV String Reversed error on Goodwe Inverter?
If your Goodwe Inverter displays String1 PV String Reversed, it indicates that the PV string is connected reversely. Check whether the PV1 and PV2 strings are connected reversely.
What causes Anti Reverse power Failure in Goodwe Inverter?
If your Goodwe Inverter shows Anti Reverse power Failure, it could be due to an abnormal fluctuation of load. If the exception is caused by an external fault, the inverter will recover automatically after solving the problem.
What does Abnormal parallel CAN communication mean on Goodwe Inverter?
If your Goodwe Inverter displays Abnormal parallel CAN communication, it means that the parallel communication cable connection is abnormal, or an inverter in the parallel system is offline. Check whether all the inverters are powered on and whether the parallel communication cables are firmly connected.
Why I am unable to log in to the parallel system interface in APP for Goodwe GW15K-ET?
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 Goodwe GW15K-ET shows Parallel IO check fail?
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.
What to do if Goodwe GW15K-ET Inverter shows Utility Loss?
If your Goodwe Inverter displays a 'Utility Loss' error, it could be due to a failure in the utility grid power supply or a disconnection in the AC cable. The alarm should clear automatically once the grid power is restored. Ensure the AC cable is properly connected and the AC breaker is turned on.
What causes Grid Undervoltage on Goodwe GW15K-ET Inverter?
A 'Grid Undervoltage' error on your Goodwe Inverter means the grid voltage is lower than the permissible range, or the duration of low voltage exceeds the requirement of LVRT. If this happens occasionally, it might be a temporary issue with the utility grid, and the inverter should recover automatically once the grid returns to normal. If it happens frequently, check if the grid voltage is within the allowed range and contact the local power company if it's not. If the grid frequency is within the permissible range, consider modifying the undervoltage protection threshold, LVRT, or disabling the undervoltage protection function after obtaining consent from the local power company. Also, ensure that the AC breaker and output cables are securely and correctly connected.
