W2FAN WARN

Name in the manufacturer's documentation (fault list): FAN WARN[1]

In plain words (editorial)

Fan warning – the manual says to check the fan's operating status; if it runs abnormally, its connection is checked inside the inverter.

When to call a service technician: Opening the inverter cover is a job for the installer. If it does not return to normal, contact your installer or Deye support.
