Ideally an inverter refrigerator is the best bet but my old refrigerator needs 300watts when on.
Camping solar panel refrigerator diy.
We ve installed the combiner box on the roof gaining access to an inconspicuous location inside the rv.
100 watt portable solar panel.

100 watt solar panel approximately 6 amps hour in direct summer sun no clouds here s an example of our calculation of how much the solar panels are generating to recharge our rv batteries.
5 hours of direct sunlight x 6 amps generated hour 30 amp hours day.
But generally they work on the same principles.
4 batteries and 3 panels would probably do.
I recently went camping with a dozen of my neighbors up to northern az out next to a lake.
Currently as we speak our self installed rv solar panels are completely running our new refrigerator.
The solar refrigerators are equipped with solar panels for the collection of solar power.
Now as the manufacturers are using more efficient refrigerators the size of that array required may go down as low as 570 watts.
Your solar panel needs to have enough power to replenish that usage using only the sun it can which is about 5 hours per day more in cloudy places.
Well folks those days are long behind us.

Remove the residential refrigerator and replace it with a 3 way refrigerator that uses propane gas then design a system that can operate most everything in your rv while boondocking except the refrigerator and ac unit.
Basically any fridge will do but the more energy efficient means a smaller solar setup is needed.
Your charge controller needs to be efficient and be able to handle the power it s given.
