What causes an Abnormal GFCI 30mA error on a Goodwe GW10K-ET Inverter?
- N
  Nicholas CochranSep 1, 2025
  An 'Abnormal GFCI 30mA' error on your Goodwe Inverter indicates that the input insulation impedance has become low during operation. If this occurs occasionally, it might be due to a cable issue, and the inverter should recover automatically once the problem is resolved. However, if the problem occurs frequently or persists, check whether the impedance between the PV string and PE is too low.

What to do for Grid Undervoltage error on Goodwe GW10K-ET Inverter?
- F
  fisherjessicaAug 31, 2025
  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 LVRT requirement. If the problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically. If it occurs frequently, check if the grid voltage is within the permissible range and contact the local power company if it is not. If the grid frequency is within range, consider modifying the undervoltage protection threshold, LVRT, or disabling the undervoltage protection function after getting approval from the local power company. Also, check the AC circuit breaker and output cables to ensure they are securely and correctly connected.

What does Grid Overfrequency mean on Goodwe Inverter?
- G
  Garrett WrightAug 30, 2025
  A 'Grid Overfrequency' error on your Goodwe Inverter indicates that the grid frequency exceeds 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 overfrequency protection threshold or disable the overfrequency protection function after obtaining consent from the local power company.

What does Grid Underfrequency mean on Goodwe GW10K-ET?
- M
  Mr. Peter SalazarAug 29, 2025
  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.

How to fix a Grid Overvoltage error on my Goodwe Inverter?
- S
  Stephen ReillyAug 28, 2025
  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 to do if my Goodwe GW10K-ET Inverter shows 'Low Insulation Res.'?
- S
  samanthahodgesAug 27, 2025
  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.

Why is my Goodwe Inverter showing a utility loss?
- C
  Craig DuarteAug 27, 2025
  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.

How to troubleshoot on-grid and backup connections in Goodwe Measuring Instruments?
- R
  rebeccacurtisAug 26, 2025
  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.

What to do if Smart Meter & CT connections are not working on Goodwe Measuring Instruments?
- K
  Kenneth FergusonAug 25, 2025
  To resolve issues with Smart Meter & CT connections in your Goodwe Measuring Instruments, ensure that the Smart Meter and CT are properly connected between the house loads and the grid. Also, make sure to follow the Smart Meter direction sign on the CT.
