Why is my Goodwe GW9.9KAU-DT Inverter showing 'AFan Fail'?

If your Goodwe Inverter displays 'AFan Fail', it indicates a fault in all of the inverter's fans. Restart the inverter and check whether the inverter can work normally. Also, make sure that the fans are working properly and are not covered or blocked.
