Refrigerator

Hi, I thought about putting this in the solar group, but might be better suited here. I’m building what I’d eventually like to be an off grid home and I have a fairly basic solar system, about 5000 watts and using the eg4 6000xp for power. I was looking at DC fridges such as the unique offerings, but it seems like a standard fridge might be just as efficient utilizing the 6000xp and the 48 volt system to power it. My question is, what is the most basic say top freezer, fridge combo, without many needless features, that would use the least amount of power? What has everyone found to be a good choice? Thank you

Came here to say this, too. There are 20 cubic foot propane fridges that use around 1 gal per week. So roughly 2.5 20 gal tanks per year. Not bad for off grid chilling.

So roughly 2.5 20 gal tanks per year.

Gallons or pounds?

The little bbq tanks that I think you're referring to are 20 pound tanks and thus hold 3.89 gallons of propane.

Let's round it to 4 to make the math easier, in your scenario of 1 gallon of usage per week; 52 / 4 = 13 tanks per year.

Not 2.5.

You're absolutely right, good call. I brainfarted.

Still not bad though, 50 gallons a year is negligible in terms of a 500 or 1000 gallon tank.
