S023-S: Errorlog derate PWR Temp.

The solar module inside the PowerRouter becomes too hot, and will limit its output.

  1. To rule out any software errors, the PowerRouter needs the latest official firmware.

  2. Is there enough space above and below the PowerRouter for proper ventilation?

  3. Visual check: Open the lower cap from the PowerRouter and verify if the fans are not obstructed.
    All fans will be activated when solar yield exceeds 2.5 kW.
