Why is my Goodwe EH Plus showing a Grid Overvoltage error?
- L
  laura72Aug 22, 2025
  A 'Grid Overvoltage' error on your Goodwe Inverter indicates that the grid voltage is exceeding permissible limits or the duration of high voltage is too long. If this occurs occasionally, it may be a temporary grid abnormality, and the inverter will recover automatically. If it happens frequently, verify that the grid voltage is within the acceptable range. If the grid voltage exceeds the permissible range, contact your local power company. If the grid frequency is within range, you may need to modify the overvoltage protection threshold, HVRT, or disable the overvoltage protection function after getting approval from the local power company. Also, ensure the AC breaker and output cables are securely and correctly connected.

What to do if my Goodwe EH Plus Inverter shows an Abnormal Ground error?
- N
  nancy07Sep 4, 2025
  An 'Abnormal Ground' error on your Goodwe Inverter can be caused by: 1. A poorly connected PE cable on the inverter. 2. Reversed L and N cable connections when the PV string output is grounded. To resolve this, check: 1. That the inverter's PE cable is properly connected. 2. Whether the L and N cables are reversed if the PV string output is grounded.

What does Anti-islanding mean on Goodwe EH Plus?
- J
  Jacob LewisSep 2, 2025
  The 'Anti-islanding' error on your Goodwe Inverter means that the utility grid is disconnected according to safety regulations, but the grid voltage is maintained due to the loads. Check whether the utility grid is disconnected.

What does Abnormal GFCI 30mA mean on my Goodwe Inverter and how to fix it?
- J
  Jennifer FloresSep 1, 2025
  An 'Abnormal GFCI 30mA' error on your Goodwe Inverter suggests that the input insulation impedance has become low while the inverter is working. 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 it happens frequently or persists, check if the impedance between the PV string and PE is too low.

What causes a PV Input Overvoltage error on a Goodwe Inverter?
- D
  David WilsonAug 30, 2025
  A 'PV Input Overvoltage' error on your Goodwe Inverter indicates that the PV array configuration is incorrect, specifically that too many PV panels are connected in series in the PV string. To fix this, check the serial connection of the PV array and ensure that the open circuit voltage of the PV string does not exceed the inverter's maximum operating voltage.

How to troubleshoot a Low Insulation Res. error on Goodwe EH Plus Inverter?
- M
  Megan NorrisAug 29, 2025
  A 'Low Insulation Res.' error on your Goodwe Inverter can be due to: 1. A short circuit between the PV string and PE. 2. A moist environment affecting the PV system, leading to poor cable insulation to the ground. To resolve this: 1. Check if the resistance of the PV string to PE exceeds 50k?. If not, find the short circuit point. 2. Verify the PE cable is correctly connected. 3. If the resistance drops on rainy days, reset the ISO.

What does a Grid Underfrequency error mean on my Goodwe EH Plus?
- K
  Kimberly GreenAug 28, 2025
  A 'Grid Underfrequency' error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency is lower than the local grid standard's requirement. If the problem occurs occasionally, the utility grid may be temporarily abnormal, 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. If the grid frequency exceeds the permissible range, contact the local power company. If the grid frequency is within the permissible range, modify the underfrequency protection threshold or disable the underfrequency protection function after obtaining the consent of the local power company.

What should I do if my Goodwe EH Plus shows a Grid Rapid Overvoltage error?
- J
  John WalkerAug 27, 2025
  A 'Grid Rapid Overvoltage' error on your Goodwe Inverter indicates an abnormal or ultra-high grid voltage. If this occurs occasionally, it may be a temporary utility grid issue, and the inverter will recover automatically once the grid returns to normal. If it happens frequently, check if the grid voltage is within the permissible range. If the grid voltage exceeds the permissible range, contact the local power company. If the grid voltage is within the permissible range, modify the grid overvoltage rapid protection threshold only after obtaining consent from the local power company.

Why does my Goodwe EH Plus Inverter display a Grid Undervoltage error?
- J
  Jordan ColemanAug 25, 2025
  The '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 occurs occasionally, it may be a temporary grid issue, and the inverter should recover automatically once the grid is normal. If it occurs frequently, check whether the grid voltage is within the permissible range. If the grid voltage is not within the permissible range, contact the local power company. If the grid frequency is within the permissible range, modify the undervoltage protection threshold, LVRT, or disable the undervoltage protection function, but only after getting approval from the local power company. Also, make sure the AC breaker and output cables are securely and correctly connected.
