How to fix an 'Over Temperature' error on my Goodwe GW6K-DT?
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 GW6K-DT 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 GW6K-DT Inverter?
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 GW6K-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.
Why is my Goodwe GW6K-DT showing 'PV Over Voltage'?
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 should I do if my Goodwe GW6K-DT Inverter 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.
What to do if my Goodwe Inverter shows a Utility Loss error?
If your Goodwe Inverter displays a Utility Loss error, it could be due to a utility grid power failure. Check if other electrical devices connected to the same grid connection point are working normally and if the main supply is normal. It could also be due to a disconnected AC circuit or AC breaker, so ensure that the upstream switches of the inverter are connected. Also, verify that the phase sequence of the AC cables are correctly connected, and the neutral wire and PE cable are properly and firmly connected.
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 GW6K-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.
