I'm into self sufficiency and my goal is to go completely off grid sometime in the future, one thing at a time. We have been using solar powered lighting in the house for over a year now and we love it.
During a wind storm about a month ago the power flickered several times and fried the compressor in the chest freezer we had been using for a year as a fridge, so getting refrigeration is first. Side note: the chest "fridge" saved us a lot of money on our electricity bill each month.
After that is wood heat, but our setup isn't ideal. Insurance company won't insure us unless a licensed pro installs the rocket mass heater. We know of nobody in this area that does that and we absolutely cannot afford to bring ernie and erica over here to do it. So, it will most likely be a wood stove. My desire is to use the wood stove to cook and bake as well as heat our home and heat water. Already use my solar oven to cook and heat water but it isn't gonna heat our home and it only works on sunny days lol!
I would like to buy a sundanzer chest fridge and run it on solar, with the option to run it on ac if we need to. Looking at their dcr154 5cf chest fridge. Gonna call and ask if they can install an ac thing. I have some solar components already but am in need of solar savvy folks to guide me.
Nice to meet you all!

Another person on permies said his very large freezer just sips power, so your post confuses me (which ain't hard to do...see below lol).
I was under the impression that a dc chest fridge run on solar wouldn't use as much power as an ac one run on solar. One reason i thought that is because the dc (power) wouldn't have to be converted to ac to be used on solar, but ac would. Hope you get my drift. I'm not considering an ac freezer. The only reason ac came into my post was that if something happened and i needed to plug it into the grid, i could. Like if the sun didn't shine for a week or something.
Here are the components i already have, which i bought a few years ago for a different project:
Renogy rover mppt 20a pwm solar charge controller 12/24v. Max solar power = 12v 260w. Or 24v 520w. Max load power = 12v 240w. Or 24v 480w
Mighty max solar 500w pure sine wave inverter. Dc to ac (in case i do decide to get the ac chest freezer)
The sundanzer chest fridge, in 90 degree air temperature, uses 240 wh/day. If my calculations are correct, this would make it 20 amps, but that sounds like an awful lot of amps. That can't be right. Probably has something to do with it being watt hours instead of just watts? Ok then, is it 240 ÷ 24 hours in a day? If so, is it .83 amps?
Somebody please help me or else put me out of my misery LOL!
