Keeping things cold

Living off grid and keeping things like food and beer cold can be a challenge especially if you're watching the watts. Something I use that works really well is a chest type freezer with an external adjustable thermostat. Something like this https://www.amazon.com/Johnson-Cont...eway&sprefix=kegerator+thermo,aps,348&sr=8-18

I've been using several of these for 8 years or so, work great, there are many other models available, look under kegerator thermostat controller.

By using a 5 or 7 cu ft freezer in this way you gain additional insulation compared to a fridge and being a chest type the cold doesn't fall out when you open the door. I live in West Texas and in the summer 112 degrees can be a pretty common day, currently living in an RV while building the house the fridges sit outside but keep everything just fine even on the hot days and use less than one KWH per day.

Since average ground temps here run in the 70-80's a root cellar isn't going to work, so what I have done is convert a freezer the same way setting the temp at 40 degrees, this allows me to store potatoes, onions, and other bulk items in a cool dark environment which saves me from having to make trips to the store an hour or more away.

Wow! A single KWH per day?!? Did you add additional insulation to it externally? Or is it just bone stock?

A side note, if you use these outside, be sure to leave the drain open, when it rains the seal on the lid, which works great at keeping air from circulating does not keep water out. It's not a big deal, more of an annoyance since we only average around 10 inches of rain a year. If you are using it as a freezer though, the rain leaking in will soon turn the inside into a huge ice cube and require defrosting to get your stuff out!

Very interesting. Thanks.

How do you tell if the chest freezer has a compressor delay?

From Amazon questions:

I fried my second freezer using this thermostat, could it has something to do with me moving the dial while the freezer is turned on (Haier freezer)?
Answer:
If it doesn't have a compressor delay, which is important as rapid on/off cycling can kill the compressor, then yes it fried it.


Oh, and welcome to the forum.
Thanks!
I've never heard of there being a compressor delay, and surprisingly two of the freezers I'm currently using are Haier brand, one of them is an original and 8 years old or so now. I wonder what would cause rapid on/off cycling, watching my solar monitoring software I can see when they turn on and off and all I've ever seen is them turn on run a bit then turn off for a while, no rapid cycling. When I use one of these I turn the freezer to it's coldest setting then let the external thermostat control things, I wonder if the freezer thermostat was set to minimum the two thermostats might fight each other causing the cycling? Don't know...
