    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 approximately 2300 watts of panels, 1kw facing southeast 1.3kw facing southwest. 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 32nd 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.
