How to resolve Internal Comm Loss on Goodwe Inverter?
For an 'Internal Comm Loss' error on your Goodwe Inverter, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes.
How to fix GFCI HCT Check abnormal on Goodwe ET?
To address a 'GFCI HCT Check abnormal' error on your Goodwe Inverter, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. This error indicates that the sampling of the GFCI HCT is abnormal.
What to do if Goodwe ET Inverter displays Relay Check abnormal?
If your Goodwe Inverter displays a 'Relay Check abnormal' error, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. This error can be caused by the relay being abnormal or short-circuited, the control circuit being abnormal, or the AC cable connection being abnormal (like a virtual connection or short circuit).
How do I fix Internal Comm Loss on my Goodwe ET Inverter?
To address an 'Internal Comm Loss' error on your Goodwe Inverter, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. If the problem persists, contact the dealer or after-sales service.
Why Goodwe ET Inverter ET did not start up with PV only?
If your Goodwe Inverter ET doesn't start up with PV only, ensure the PV voltage is greater than 180V (230V is needed to enter on-grid mode). Also, verify that the polarities (+/-) are correctly connected between the ET and PV panels and not reversed.
How to troubleshoot on-grid and backup connections in Goodwe Measuring Instruments?
To resolve on-grid and backup connection problems with Goodwe Measuring Instruments, verify that the on-grid is connected to the power grid and the backup is connected to the loads. Also, check that the polarities (e.g. L1/L2/L3/N) are correctly aligned.
Why is my Goodwe ET showing a utility loss?
If your Goodwe Inverter is showing a utility loss, it could be due to a failure in the utility grid power or because the AC cable is disconnected, or the AC circuit breaker is off. Once the grid power supply is restored, the alarm should automatically clear. Ensure the AC cable is securely connected and the AC circuit breaker is turned on.
What to do if my Goodwe Inverter shows 'Low Insulation Res.'?
A 'Low Insulation Res.' error on your Goodwe Inverter typically means one of two things: either the PV string is short-circuited to PE, or the PV system is in a moist environment with poorly insulated cables. To resolve this: 1. Check if the resistance of the PV string to PE exceeds 50k?. If not, identify and fix the short circuit. 2. Verify that the PE cable is correctly connected. 3. If the resistance drops on rainy days, reset the ISO via the SolarGo app.
How to fix a Grid Overvoltage error on my Goodwe ET Inverter?
A 'Grid Overvoltage' error on your Goodwe Inverter indicates that the grid voltage is outside the acceptable range or the duration of high voltage exceeds the HVRT requirement. Here's what you can do: 1. If this occurs occasionally, it might be a temporary grid abnormality. The inverter should automatically recover once the grid returns to normal. 2. If it happens frequently, check if the grid voltage is within the permissible range. If it exceeds this range, contact your local power company. 3. Also, ensure the AC circuit breaker and output cables are securely and correctly connected.
What does Grid Underfrequency mean on Goodwe ET?
A 'Grid Underfrequency' error on your Goodwe Inverter indicates that the grid frequency is lower than the local grid standard. If this occurs occasionally, it may be a temporary issue with the utility grid, and the inverter should recover automatically. If the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it exceeds that range. If the grid frequency is within the permissible range, you may need to modify the underfrequency protection threshold or disable the underfrequency protection function after obtaining consent from the local power company, or close the “Grid Underfrequency” function.
