Running fridge Norcold N611 off inverter?

My Norcold N611 runs normally off either propane and the house batteries for the circuit board with minimum amp draw, or off 120v. I have 2 group 24 batteries and was wondering in the event I run out of propane, can I run the fridge off the inverter? If so, how long with 2-85ahr? Could solar panels recharge the batteries to keep it going indefinitely?

Short answer is yes,, HOWEVER

Two Group 24's is about 150 amp hours, 50-60 usable amp hours (assumes MARINE/deep cycle) or 800 watt hours at the C/20 rate.. With conversion loss make that 600 watt hours at the C/20 rate

The fridge draws around 350,, So you have 1 hour of battery run time if you are lucky

Upgrade those G-24 to GC-2 and you get 230 total Amp hour 115 usable, (These are DEEP CYCLE no mention of marine). so that's what, around 1,000 watt hours, with the fast discharge perhaps 2 to 2.5 hours of battery life..

Of course your alternator (while moving) will add a bit to that but frankly not enough.

I would call this a bad idea.

(NOTE: Tried it, with GC-2s, Was not happy with result).
