fet = 37 deg

has been like this fir days . .environment temps about 18 deg day and 12 night . maybe the cap temps . is thus normal??

    Is this a new? I know my Prosine will run the fan with a load of about 300 watts, pretty much continuously unless the ambient temps are below about 50 degrees (10 degrees C) I also know it will over heat with a load around this high without the fan. I had the fan go out a couple years ago.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    Definately not normal for a 24V FX. Call Outback for a kit or RMA.
    Oh yea,  does it start a large load like a 1500 watt heater?

    spoke to dealer . they say it needs a look at . so will disconnect after weekend and they say it should be a same day turnsround. .. so looking like my first power cut in over 10 years .. my neighbors on the grid however have many power cuts per year , as we are at the end of a spur line..

    Seems like I have read that low batteries may contribute to the inverter fan turning on? I'm not sure though.
