Running/powering and RV fridge from the inverter is a waste of battery power, 300+ watts for the heating elements uses 30 to 40 amps D.C. Battery power into the inverter to get the 3 amps 120vac for the fridge heating elements,
The best thing is to use propane for the fridge when not connected to shore power, this RV has an RV gas electric fridge, I power it exclusively from LP unless I run out of propane, in which case I switch to electric and inverter while I drive to the LP station,
For 7 years with a previous RV I did power a residential fridge from inverter, with 649watts of solar pane on the roof and 500+ AmpHrs of battery bank, that fridge compressor only need 100 watts of electric power
RV gas electric absorption fridge need 3 to 4 times as much electric power,
I use l.p. And keep electric as emergency backup operation
With this fridge
