No external fan added on here. It has on internal fan as I recall. And installed as specified.

A Victron muktipass at room temp is 2,400 Watts continuous.  At 104F it's 2,200 Watts at 150 degrees it's 1,700 Watts.

A fan might help 

Foretravel installed inverter fans on the compartment divider walls on later units if memory serves me.

Many Foretravels have a temperature triggered exhaust fan in the bay where the inverter is. Mine does. It sucks air out of the bay and exhausts it through the floor.  It is there no matter what inverter came with the coach.  Any inverter running at full power for any length of time (not common) will generate heat.  This is not a Victron Multiplus issue, it is common to all inverters.

I see no fans in my bays, maybe newer ones have them.

Look on you electrical circuit drawings.  Secondary panel, inverter circuits, #3.  Inverter Fan.  Mine is on the rear wall of the main bay where inverter is located (on the front wall). I know on 97 40' coaches the original inverter is mounted in a steel frame hanging from the ceiling on the drivers side. Our 36' 2001 is different.  I am not sure when and on what models this changed.  Another difference that demonstrates that it is hard and often incorrect to make sweeping generalizations.

None on my 97,99 or 2000 either. 03 does have one.

The prosine installation may have necessitated the fan install. 

The Prosine  unit(s) starts to reduce it power past 25 degrees C. 

The magnum unit outputs full 3,000 watt rating to 60 degrees C.

The fan and the prosine were probably less money than the 2812 I think they later went to.

Think you are right Bob, the Prosine appears to produce a lot more heat than the older Xantrex  and Outback inverters I have had.

My Victron replaced a Prosine.  I know the exhaust fan works, I have forced it to come on.  The AquaHot also heats up that bay in my 2001 U320 36' coach.  I don't think I have ever heard the exhaust fan come on no matter what,  Prosine or Victron or Aqua Hot.  The floor in the coach above the bay is comfortably warm in colder weather when using the AH.

Mine never came on either. Checked the snap disc type thermostat and found it defective. Replaced with a adjustable one and set it to 125 F.  Now come on when inverter in in heavy charge mode. Of course this is in Texas where ambient temp is already 90 F.  so it doesn't take much. Aux compressor and hyd slide pump are in same compartment.
Believe Bob is correct saying the Prosine derates at higher temps.

Interesting that the Prosine capability drops off after 77°F.  The AquaHot can make that bay that warm all by itself.

Roger, my coach came without the diagrams and books that explain the systems onboard. Anyway I can download these, or do I have to call Foretravel for them ?

My coach has all the electrical stuff moved inside, in the cabinet the washer dryer resided in. The Lithium batteries don't like to be to hot or to cold and the cabinet doors are louvered so they get good ventilation. Seems to work fine.

You can get them from FT for some $ or find someone with a model in your year that includes your build number.  I can send what I have but they are probably not exactly what you have but close.  PM an email address and I will send them.

Folivier,

Yours are the same year and model, probably much more likely than not that they are more accurate than mine.  Better that you send them to him.
