    An average, efficient fridge will consume about 1 - 2 KWh per day. 

    Do you get cloudy days?  weeks ?

    Using solar to power a refrigerator is probably the most difficult/expensive with the least payback thing in solar.

    Unless you are replacing a propane fridge. Then it is very cost effective.
    Island cottage solar system with appriximately 2500 watts of panels, 1kw facing southeast 1.3kw facing southwest 170watt ancient Arco's facing due south. All panels in parallel for a 24 volt system. Trace DR1524 MSW inverter which has performed flawlessly since 1994. Outback Flexmax 80 MPPT charge controller four 467A-h AGM batteries. Insignia 11.5 cubic foot electric fridge 1/4hp GSW piston pump. My 31st year.

    Stinky3773 ,  Are you interested in operating cost savings?  If so, it is very hard to make a financial case for solar vs. grid power. I would assume that you are looking for some level of autonomy when grid power goes down?

    I always have more questions than answers. That's the nature of life.
