What to do if my Goodwe GW8K-DT Inverter shows 'Utility Loss'?
- B
  Benjamin BrownAug 23, 2025
  If your Goodwe Inverter displays a 'Utility Loss' error, it could be due to several reasons. First, check if there is a power failure in the utility grid by checking other electrical devices. Second, ensure that the AC circuit or AC breaker is properly connected. Finally, verify that the phase sequence of the AC cables is correctly connected, and the neutral wire and PE cable are firmly connected.

What to do if my Goodwe GW8K-DT displays 'DC inject High'?
- L
  Leslie WrightSep 1, 2025
  If your Goodwe Inverter shows 'DC inject High', it means the DC injection exceeds the allowed range. Check whether the software version is the latest one. Restart the inverter and check whether the inverter can work properly.

What does 'Ground I Fail' mean on my Goodwe Inverter?
- J
  Jason HernandezAug 31, 2025
  If your Goodwe Inverter displays 'Ground I Fail', it indicates that the input insulation impedance to the ground is decreasing during operation. Check if the inverter's working environment meets the requirements; for example, high humidity on rainy days can cause this. Also, ensure that the components and the AC side are properly grounded.

What does 'ARC Fault' mean on my Goodwe Inverter and how to fix it?
- J
  Jennifer LambertAug 30, 2025
  If your Goodwe Inverter is showing an 'ARC Fault', it could be due to the PV string cables arcing or being in poor contact. Check whether the PV terminals and cables are connected properly. If the fault occurs frequently, contact after-sales service.

Why is my Goodwe GW8K-DT Inverter showing 'PV Over Voltage'?
- J
  Jasmine HurstAug 28, 2025
  If your Goodwe Inverter displays 'PV Over Voltage', it means that too many PV modules are connected in series, causing the open-circuit voltage to exceed the operating voltage. Check whether the PV string input voltage is consistent with the value displayed on the LCD and meets the maximum input voltage requirements.

What causes 'Fac Fail' on a Goodwe GW8K-DT?
- K
  kanekaraAug 27, 2025
  If your Goodwe Inverter shows 'Fac Fail', it indicates that the utility grid frequency is out of the allowed range. Check whether other electrical devices under the same grid connection point is working normally, and whether the main supply is normal. Ensure the grid frequency is within the allowed range and that the phase sequence of the AC cables are connected correctly, and the neutral wire and PE cable are properly and firmly. If the fault happens occasionally, it may be due to instantaneous utility grid frequency change and does not need to be handled.

What does 'Vac Fail' mean on my Goodwe GW8K-DT Inverter?
- C
  Caitlin GonzalezAug 27, 2025
  If your Goodwe Inverter shows 'Vac Fail', it means the utility grid voltage is out of the allowed range. Make sure that the grid voltage is within the allowed range. Also, ensure that the phase sequence of the AC cables are connected correctly, and the neutral wire and PE cable are properly and firmly.

What to do if my Goodwe GW8K-DT Inverter displays 'Isolation Fail'?
- K
  Kimberly KnappAug 26, 2025
  If your Goodwe Inverter is showing an 'Isolation Fail' error, it could be due to: 1. A short circuit to the ground in the PV system. Check the PV input cables for any breaks. 2. A moist environment affecting the PV system's insulation. Ensure the module frames and metal bracket are securely grounded. 3. Also, check that the AC side is properly grounded.

How to fix an 'Over Temperature' error on my Goodwe GW8K-DT?
- R
  Robert FrancisAug 25, 2025
  If your Goodwe Inverter is showing an 'Over Temperature' error, there are a few things to check: 1. Ensure that the inverter has adequate ventilation and space for heat dissipation. 2. Verify that the ambient temperature is not too high. 3. Confirm that the fans are working correctly and are not blocked.
