[RE-wrenches] Off-grid refrigerator

[Bob-O Schultze]

Assuming you have a sinewave inverter t this point, I agree with Jerry about going to a 120vac fridge. However, I would suggest going to your computer before the appliance store. For Kathleen and I, Energy Star rated is the starting point. There is some really good info here:
https://library.cee1.org/content/qualifying-product-lists-residential-refrigerators <https://library.cee1.org/content/qualifying-product-lists-residential-refrigerators>
If you can find a good one with defeat-able auto defrost, that’ll save a bunch’o watts. Within the ES ratings there are still models which are more or less efficient than others. Whatever you get will use more power than your RF12, but that’s partly because you probably won’t find a good fridge under 18-19 cu.ft. You will love the 35-40% increase in capacity, but it isn’t a completely free lunch. So throw a few more watts out in the sun. Hell, at today’s PV prices, throw up a couple more kilowatts!
Good Luck, Bob-O

This has been on topic many times and im sure it will be many more times, l have many off grid customers that at one point said the same thing. I asume you have 120 vac, just measure the space you have and go to your local appliance store and pick one out that has the good low usage compressor meets all the energy star ratings and will fit. I have customers that have two big stainless units living off grid and thats just one well two of the many common house hold items now that are energy eff.

Hello Off-grid Wrenches,

After 10+ years my Wife is finally sick of our Sunfrost RF-12. We'd like to upgrade to something a little more modern that doesn't leak water all over the floor when it's humid

For you off-grid installers what's your go to refrigerator recommendation? I'm going to go through the energy star website but I thought I'd consult with the experts too. I'd like to find something that has a form factor similar to the Sunfrost although I know that's going to be hard to find.

Thanks,
Will White
