We have the residential refrigerator. Had I to do it over again, I would choose the rv option. We had 480 watts of solar panels installed and were able to run the refrigerator for 6 days on the batteries before we lost sunshine. Probably the best I will be able to do, but I'm still not entirely happy with the situation.
