What to do if my Goodwe HT 73-136kW shows a 'Utility Loss' error?
- S
  Stephanie RodriguezAug 21, 2025
  If your Goodwe Inverter displays 'Utility Loss', it could be due to a utility grid power failure or a disconnection in the AC circuit or AC breaker. First, check if other electrical devices connected to the same grid point are working. Also, ensure the main power supply is normal and that the inverter's upstream switches are properly connected. Finally, verify that the phase sequence of the AC cables is correct and that the neutral and PE cables are firmly connected.

Why does my Goodwe HT 73-136kW Inverter show a 'Vac Fail' error?
- N
  Nathan WilliamsAug 23, 2025
  If your Goodwe Inverter displays 'Vac Fail', it means the utility grid voltage is outside the acceptable range. Ensure the grid voltage is within the allowed range. Also, check that the phase sequence of the AC cables is correct, and the neutral wire and PE cable are properly and securely connected.

What to do if my Goodwe Inverter displays 'Isolation Fail'?
- T
  Timothy HendricksAug 25, 2025
  If your Goodwe Inverter shows 'Isolation Fail', it may be caused by a short circuit to the ground in the PV system or moisture affecting the circuit's insulation. Check the PV input cables for any breaks. Ensure the module frames and metal bracket are securely grounded, and verify the AC side is properly grounded. In Australia and New Zealand, inverters with WiFi will send an email about the fault automatically. If there is no WiFi, the inverter's buzzer will sound for 1 minute, repeating every 30 minutes if the problem continues.

How to fix 'Over Temperature' error on Goodwe HT 73-136kW Inverter?
- C
  Christian MartinAug 27, 2025
  If your Goodwe Inverter displays 'Over Temperature', it could be due to poor ventilation, high ambient temperature, or the inverter working improperly. Check the installation environment to ensure it meets ventilation requirements for heat dissipation. Make sure the fans are working correctly and are not blocked. Also, verify that the operating ambient temperature is not too high.

What does 'Fac Fail' mean on a Goodwe Inverter?
- B
  bandersonAug 27, 2025
  If your Goodwe Inverter displays 'Fac Fail', it indicates that the utility grid frequency is outside of the allowed range. Check whether other electrical devices under the same grid connection point are working normally, and whether the main supply is normal. Ensure the grid frequency is within the allowed range. Make sure that the phase sequence of the AC cables are connected correctly, and the neutral wire and PE cable are connected properly and firmly. If the fault occurs occasionally, it may be due to an instantaneous utility grid frequency change and may not require action.

What causes 'Ground I Fail' on a Goodwe HT 73-136kW Inverter?
- J
  Jodi HaneyAug 31, 2025
  If your Goodwe Inverter displays 'Ground I Fail', it means the input insulation impedance to the ground has decreased during operation. Check if the inverter's working environment meets the requirements; for example, high humidity on rainy days may cause this. Also, ensure that the components and the AC side are properly grounded.
