The fridge needs D.C.all the time for the controls
It should naturally run on l.p. gas,
If set on auto, it will default to 120vac electric, If shower power is connected, or generator power is on
Very few fridges use D.C.power to keep cold, most are only Two Way power, Not three way power
Check the inverter, not the control panel
Goto the inverter, look for the led lights, no lights no power, either cable is not connected, or fuse is bad/blown
Tripplites are well built,
I have forgotten to turn mine off when working on my batteries, no damage was ever done, just cable sparks, at the battery
