Battery Life With a Residential Fridge

Funny thing is, this fridge draws as much as the 10cu/ft ones I looked at. Also, the really small one I have at work has the same specs. Go figure.....
Specs on the inverter call for .5a no load draw but when I measure it is .18a???
Fridge cooled in less than 2 hours with nothing in it to help, still empty and it is at 0deg freezer and 28 fridge set on 4 out of 6. Ambient temp is about 75deg. Going to open the garage and let the sun hit it for a while and see.
Compressor temp is the same as when plugged into the house and no additional noise on the cheap MSW inverter.

Correct.

Most fridges use the same size compressor the big difference you will see is the bigger fridges will have larger sized coils and more insulation..

I have a small 1.2 cu ft dorm fridge in my basement, the walls are not as thick as my 10 cu ft fridge. The dorm fridge draws the same amount of current but because it has less insulation it runs longer and more often than the 10 cu ft fridge..

Typically home fridges will reach correct temps within 1 hr or so and start cycling unlike a absorbsion fridge which can take 12 to 24hrs to reach a stable temp.

Home fridges also rebound much faster after being opened so if you are in the fridge often it doesn't take much time for the fridge to get back to the proper temps.

High ambient temps doesn't seem to bother ours, I closed off the old RV fridge top and bottom vents and our fridge is open to the inside of the trailer.. While traveling the inside temps in the trailer have gotten up to 90F but The run time doesn't seem to vary much from 20-22 minutes per hr..
