What to do if Goodwe SMT Inverter shows PV String Reversed?
If your Goodwe Inverter is showing 'PV String Reversed (Str1- Str12)', it means that the PV string is connected reversely. Check whether the PV strings are connected reversely.
How to fix Internal Comm Loss on Goodwe SMT?
If your Goodwe Inverter displays 'Internal Comm Loss', disconnect the AC output switch and DC input switch, then connect them again after 5 minutes.
What to do if my Goodwe SMT Inverter is showing a Utility Loss?
If the Goodwe Inverter shows a 'Utility Loss' error, it means either the utility grid power has failed or the AC cable is disconnected, or the AC breaker is off. Once the grid power is restored, the alarm should clear automatically. Ensure the AC cable is properly connected and the AC breaker is on.
What should I do if my Goodwe Inverter has Utility Loss?
If your Goodwe Inverter reports a Utility Loss, follow these steps: 1. Disconnect the DC switch and take off the AC connector. 2. Measure the voltage between line and neutral in the connector to ensure it conforms to the grid-connected specification of the inverter. 3. If it doesn't, check if the distribution switch is connected and the grid is normal. 4. If it does, reconnect the AC connector and DC connector.
What to do if Goodwe SMT displays AC Voltage Failure?
If your Goodwe Inverter displays an AC Voltage Failure, here’s what you can do: 1. Disconnect the DC switch and take off the AC connector. 2. Measure the voltage between line and neutral in the connector to ensure it conforms to the grid-connected specification of the inverter. 3. If it doesn't, check the grid wiring. 4. If it does, connect the AC connector and reconnect the DC switch; the inverter will connect automatically.
What to do if Goodwe Inverter shows Ground I Failure?
If your Goodwe Inverter shows a Ground I Failure, try the following: 1. Disconnect the DC switch. 2. Check the insulation of the PV string wiring to earth. 3. Reconnect the DC switch again.
What to do if my Goodwe Inverter has AC Frequency Failure?
If your Goodwe Inverter is experiencing an AC Frequency Failure, the PV inverter will automatically restart when the frequency returns to normal.
What to do if my Goodwe Inverter is not displaying anything?
If your Goodwe Inverter has no display, take these steps: 1. Disconnect the DC switch and take off the DC connector. 2. Measure the voltage of the PV string. 3. Plug in the DC connector and reconnect the DC switch. 4. If the voltage is less than 70 V, check the PV string configuration.
What to do if my Goodwe SMT Inverter shows Utility Loss?
The Goodwe inverter may display a 'Utility Loss' error due to a utility grid power failure or a disconnected AC circuit/breaker. The alarm should clear automatically once the grid power is restored. Ensure the AC cable is properly connected and the AC breaker is switched on.
What causes Grid Rapid Overvoltage on Goodwe Inverter?
A 'Grid Rapid Overvoltage' error on your Goodwe inverter indicates an abnormal grid voltage or that an ultra-high voltage has triggered the fault. If this happens occasionally, it may be due to a short-term grid abnormality, and the inverter should recover automatically. If it occurs frequently, check if the grid voltage is within the allowed range and ensure the AC side circuit breaker and output cables are properly connected.
