As an side issue, I kept a watt meter on my tiki bar fridge for 2 months living outside in the Florida summer.
(August September, peak hurricane season)
It is a fairly new Whirlpool side by side with ice and water in the door. It averaged just shy of 2KWH a day. (61.2 days 120KWH)
That would be less than 1KWH after sundown and it would tolerate running half that time at night without seriously affecting the contents. It is clear the fridge is not your big load.
You could keep that going with one big battery and a solar collector that was around 2x the running load. The average load is ~83 watts and some storage would allow you to average that load.
The other critical load for me are the well pumps.
