I like the idea versatility of the RV propane/120v fridges, but from what I understand the conventional house/apartment fridges are actually much more efficient on electricity. I just haven't sat down and done the math to figure out of an electric fridge is feasible to run 24/7 off solar/battery system only, and what size system it would take to do so...
My fridge/freezer is 4.5 cf, it holds enough for a week or so. I had it left over from college and decided to use it.
300 watts of solar is more than enough for me to run the fridge, fantastic fan, and some fans for my pups when I'm not there continuously for probably a few days.
I'm frugal with energy use so it's also enough most of the time to not have to run the generator at all. I'll cook on a bbq grill, or stove top inside (propane).
I bought 225ah interstate deep cycle batteries as sort of a test run before I go fully solar and probably go to Trojans.
Can't complain, it was fun learning to install, I can add a 4th panel for 400 watts and add batteries if needed.
