What causes an ExFan Failure on a Goodwe Inverter?
An 'ExFan Failure' on your Goodwe Inverter can be due to an abnormal fan power supply, a mechanical issue, or the fan aging and becoming damaged. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem continues, further assistance may be needed.
What should I do if my Goodwe Inverter displays a DC-SPD error?
A 'DC-SPD' error on your Goodwe Inverter suggests that the inverter has been struck by lightning. To address this: 1. Improve the lightning protection facilities around the inverter. 2. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem continues, further assistance may be needed.
What causes a Fac Fail error on a Goodwe HT Inverter?
A 'Fac Fail' error on a Goodwe Inverter indicates a utility grid exception, where the actual grid frequency change rate doesn't meet the local grid standard. If it happens occasionally, the grid may be temporarily abnormal, and the inverter will recover automatically when the grid returns to normal. If it happens frequently, check if the grid frequency is within the allowed range. If the grid frequency exceeds the limit, contact your local power company; if it is within range, further assistance may be needed.
How to troubleshoot an AFCI Fault on a Goodwe Inverter?
An 'AFCI Fault' on your Goodwe Inverter can occur if the DC string terminal is not firmly connected or if the DC cable is broken. Please check that the wirings of the PV modules are correct according to the instructions in the user manual.
What does Relay Fail mean on Goodwe Inverter?
A 'Relay Fail' error on a Goodwe Inverter can be caused by an abnormal or short-circuited relay, an abnormal control circuit, or an abnormal AC cable connection such as a loose connection or short circuit. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem continues, further assistance may be needed.
Why is my Goodwe HT Inverter showing a PV Over Voltage error?
A 'PV Over Voltage' error on your Goodwe Inverter means that too many PV modules are connected in series, causing the open-circuit voltage to exceed the operating voltage. Check that the PV string input voltage matches the value displayed on the LCD screen and that the PV string voltage meets the maximum input voltage requirements.
What does ISO Fail mean on a Goodwe Inverter?
An 'ISO Fail' error on your Goodwe Inverter suggests that the PV system is short-circuited to the ground or is in a moist environment with poor insulation. Check the PV input cables for any breaks, ensure the module frames and metal bracket are securely grounded, and verify that the AC side is properly grounded.
What causes a Vac Failure on a Goodwe Inverter?
A 'Vac Failure' on your Goodwe Inverter indicates that the utility grid voltage is outside the allowed range. To resolve this, ensure that the grid voltage is within the permissible limits and that the phase sequence of the AC cables are correctly connected, and the PE cable is properly and firmly connected.
How to fix an 'Over Temperature' error on a Goodwe HT?
If your Goodwe Inverter is showing an 'Over Temperature' error, it may be installed in a location with poor ventilation, the ambient temperature might be exceeding 60°C, 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 the ventilation and heat dissipation. If both are normal, it may indicate a need to contact support.
