What does IFan Fail mean on my Goodwe GW8KAU-DT Inverter?
An IFan Fail error on your Goodwe Inverter indicates a fault in the internal fan of the inverter. Restart the inverter and check whether the inverter can work normally.
How to fix an 'Over Temperature' error on my Goodwe Inverter?
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.
What to do if my Goodwe Inverter displays 'Isolation Fail'?
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.
What does 'Vac Fail' mean on my Goodwe GW8KAU-DT?
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 causes 'Fac Fail' on a Goodwe GW8KAU-DT?
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 ARC Fault mean on a Goodwe GW8KAU-DT Inverter, and how do I fix it?
An ARC Fault error on your Goodwe Inverter suggests that the PV string cables are arcing or are in poor contact. Check whether the PV terminals and cables are connected properly. Clear the error messages.
What should I do if my Goodwe GW8KAU-DT displays a PV Over Voltage error?
A PV Over Voltage error on your Goodwe Inverter can occur if excess PV modules are connected in series, causing the open-circuit voltage to be higher than the operating voltage. Check whether the PV string input voltage is consistent with the value displayed on the LCD and verify that the PV string voltage meets the maximum input voltage requirements.
Why does my Goodwe GW8KAU-DT Inverter show a Fac Fail error?
A Fac Fail error on your Goodwe Inverter indicates that the utility grid frequency is out of the allowed range. Check whether other electrical devices connected to the same grid connection point are working normally, and whether the main supply is normal. Make sure that the grid frequency 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 connected. Pay attention to the frequency of the fault. If it happens occasionally, the fault may be caused by the instantaneous utility grid frequency change and does not need to be handled.
What does 'IFan Fail' mean on my Goodwe Inverter?
If your Goodwe Inverter shows 'IFan Fail', it means there is a fault with the internal fan of the inverter. Restart the inverter and check whether the inverter can work normally. For internal fan faults, contact after-sales service.
What does 'DC Bus High' mean on my Goodwe GW8KAU-DT?
If your Goodwe Inverter shows 'DC Bus High', it may indicate an internal fault. Ensure that the software version is the latest one. You can also try restarting the inverter to see if it resolves the issue.
