Fridge pulls about 2 amps at 120 VAC, so 20 amps at 12 VDC times 1.3 for efficiency loss through the inverter. So about a 26 amp load on the alt while the fridge is running. Best I can remember the DDEC and all the other stuff is about 50 amps.Our coach doesn't have a Duvac system . The alternator now has two hot terminals now , so I did a search about that and Duvac came up . The extra hot got me thinking about charging house batteries while traveling without merging them .
I find very little reference to the DUVAC system, what I do see leads me to believe it is made for rigs that have both 24 and 12 VDC. This is the very first reference to DUVAC and Newells that I recall in ten years of forum membership.
Does your coach have a DUVAC system, or did you just get an alternator with two hot terminals?
