There are the rare dc powered refrigerators that are actually more efficient than the inverter types.
Basically any fridge will do but the more energy efficient means a smaller solar setup is needed.
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.

The photovoltaic cells then convert the solar energy into electricity which is later stored in a battery.
When the rvs first started to integrate residential fridges these systems were around a kilowatt.
Your charge controller needs to be efficient and be able to handle the power it s given.
