What to do if my Goodwe GW73KLV-HT Inverter shows a 'Utility Loss' error?
- J
  Jeffrey BowersAug 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 Inverter show a 'Vac Fail' error?
- D
  Dean HinesAug 22, 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'?
- S

  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 GW73KLV-HT Inverter?
- J
  Jasmine DavisAug 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 GW73KLV-HT Inverter?
- M
  Melanie JuarezAug 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.

How to troubleshoot 'ARC Fault' on Goodwe GW73KLV-HT Inverter?
- E
  elawsonAug 29, 2025
  If your Goodwe Inverter shows 'ARC Fault', it indicates that the PV string cables are arcing or have poor contact. Check the PV terminals and cables to ensure they are properly connected. Clear the error messages. If the fault occurs frequently, contact after-sales service.

What causes 'Ground I Fail' on a Goodwe Inverter?
- K
  Kristen TuckerAug 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.
