Why is my Goodwe HT showing 'BUS-start Fail'?
If your Goodwe Inverter is showing a 'BUS-start Fail' error, it could be due to the output power of the PV string being too low, or an abnormal control circuit. Try disconnecting the AC output switch and DC input switch, waiting 5 minutes, and then reconnecting them. If the problem persists, contact your dealer or after-sales service.
What to do if my Goodwe HT Inverter displays 'DC-SPD'?
If your Goodwe Inverter shows 'DC-SPD', it indicates that the inverter was struck by lightning. As a first step, improve the lightning protection around the inverter. Then, disconnect the AC output switch and the DC input switch, wait 5 minutes, and reconnect them. If the problem continues after these steps, contact your dealer or after-sales service.
What does 'Night BUS Fault' mean on my Goodwe Inverter?
If your Goodwe Inverter displays the 'Night BUS Fault' message, it means there is a problem with the utility grid power or the AC cable is disconnected, or the AC breaker is off. To attempt a fix, disconnect the AC output switch and DC input switch, wait 5 minutes, then reconnect them. If the issue persists, contact your dealer or after-sales service.
What to do if my Goodwe Inverter displays 'Relay Fail'?
If your Goodwe Inverter is showing a 'Relay Fail' error, it could be due to several reasons: the relay itself is abnormal or short-circuited, the control circuit is malfunctioning, or there's an issue with the AC cable connection, such as a loose connection or short circuit. To resolve this, disconnect the AC output switch and DC input switch, wait 5 minutes, and then reconnect them. If the problem continues, contact your dealer or after-sales service for further assistance.
Why does my Goodwe HT Inverter show 'Fac Fail'?
If your Goodwe Inverter displays 'Fac Fail', it indicates a utility grid exception where the grid frequency change rate doesn't meet local standards. If this happens occasionally, the grid may be temporarily abnormal, and the inverter should recover automatically once the grid returns to normal. However, if it occurs frequently, verify that the grid frequency is within the permissible range. Contact your local power company if the grid frequency is outside of the allowed range. If the frequency is within range, contact your dealer or after-sales service for assistance.
What to do if my Goodwe HT shows a Utility Loss error?
If you're experiencing a 'Utility Loss' error with your Goodwe Inverter, it could be due to a failure in the utility grid power supply or disconnection of the AC cable, or the AC breaker might be off. Once the grid power is restored, the alarm should clear automatically. Ensure the AC cable is properly connected and the AC breaker is turned on.
What does CPLD Error mean on a Goodwe Inverter?
A 'CPLD Error' on your Goodwe Inverter can be caused by a temporary abnormality due to environmental factors or damaged internal components. 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 does my Goodwe HT show a PV Voltage Low error?
A 'PV Voltage Low' error on your Goodwe Inverter indicates that sunlight is weak or changing abnormally. If this occurs occasionally, it may be due to abnormal sunlight, and the inverter will recover automatically. If it occurs frequently, further assistance may be needed.
What causes SPI Comm Fail on Goodwe HT?
A 'SPI Comm Fail' error on your Goodwe Inverter could be due to the chip not being powered on or a wrong chip program version. Disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. If the problem persists, further assistance may be needed.
What does BUS-start Fail mean on a Goodwe Inverter?
A 'BUS-start Fail' error on your Goodwe Inverter can occur if the output power of the PV string is too low or if the control circuit is abnormal. 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.
