OK, thanks every one for your replies!


The biggest issue is voltage drop.

My 3 way fridge works GREAT on 12 volts--so long as I'm plugged into shore power. On batteries only--even though I have 556 amp-hours and 256 watts of solar it doesn't work well at all.

If you want to "fix" the problem, then add a dc to DC charger and set the voltage at 14.8.


Regards, Don
My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

for about $500 you can upgrade the Cooling unit to one of the Amish Built ones. My old cooling unit failed and I installed a new Amish one about 2 weeks ago. So far the performance of the new unit is substantially better on AC, DC and Propane. At 100F outside the Fridge stayed at 35 and the Freezer kept the Ice Cream frozen solid. I had it on DC while driving and Propane while dry camping
