Residential refrigerators don't consume a lot of energy. They are very efficient. The inverter must be sized for the startup current of the refrigerator, but shortly after the startup inrush the current level drops to a moderate level. Once the refrigerator is down to temperature it'll stay there for hours - they are much better insulated then gas absorption types. So if you integrate or average the energy usage over a day it's quite low.
So the bottom line is that you'll need a 1 to 2 thousand watt inverter to get the refrigerator started and good batteries and properly sized wires to handle that short burst of energy, but averaged over the day the total energy usage will be quite low.
You can minimize this even further by not opening the door unnecessarily or maybe disabling the defroster.
It's kind of tlike a microwave - short bursts of large amounts of energy but not much averaged over the day..
