What does 'IFan Fail' mean on a Goodwe Inverter and how to fix it?
If your Goodwe Inverter displays 'IFan Fail', it means there is a fault with the internal fan. Restart the inverter to see if it works normally. As there is a fault in the internal fan, contact after-sales service.
Why does my Goodwe HT 73-136kW 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 73-136kW 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.
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 HT 73-136kW 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.
