What to do if my Goodwe Inverter shows a Utility Loss error?
If your Goodwe Inverter shows a Utility Loss error, it could be due to a failure in the utility grid power or disconnection of the AC cable. First, the alarm should clear automatically once the grid power is restored. If not, check to ensure the AC cable is properly connected and the AC breaker is turned on.
How to fix Over Temperature error on Goodwe UT Inverter?
If your Goodwe Inverter is overheating, it might be installed in a poorly ventilated area, the ambient temperature may be too high (exceeding 60?), or there could be a fault with the internal fan. Check the ventilation and ambient temperature around the installation point. If ventilation is poor or the temperature is too high, improve ventilation and heat dissipation.
What causes Vac Failure on a Goodwe UT Inverter and how to resolve it?
A Vac Failure on your Goodwe Inverter indicates that the utility grid voltage is outside the allowed range. Check that the AC output voltage of the inverter meets grid requirements. Also, ensure the phase sequence of the AC cables is correct, and the neutral wire and PE cable are connected properly and firmly.
What does ISO Fail mean on my Goodwe UT?
An ISO Fail on your Goodwe Inverter can occur if the PV string is short-circuited to the ground, or if the PV system is in a moist environment with poor insulation to the ground. Check the PV input cables for any breaks. Also, verify that the module frames and metal bracket are securely grounded, and that the AC side is properly grounded.
Why does my Goodwe Inverter show a Fac Fail error?
A Fac Fail error on your Goodwe Inverter means the utility grid frequency is out of the allowed range. If this occurs occasionally, the utility grid may be temporarily abnormal; the inverter should recover automatically once the grid returns to normal. If it happens frequently, check if the grid frequency is within the permissible range.
How do I fix an AFCI Fault on my Goodwe Inverter?
An AFCI Fault on your Goodwe Inverter can occur if the PV string terminal is not firmly connected or if the DC cable is broken. Please check the wiring of the PV modules to ensure they are correct according to the user manual requirements.
What causes a PV Reverse Fault on a Goodwe UT Inverter?
A PV Reverse Fault on your Goodwe Inverter indicates that the PV string is connected reversely. Check whether the PV strings are connected reversely.
What to do if my Goodwe Inverter displays a PID Error?
A PID Error on your Goodwe Inverter can be caused by abnormal grounding or an abnormal PID module. Check whether the DC and AC wirings are abnormal. Also, check if the PID module itself is working correctly.
