Small Residential Freezer
How would you calculate how many amp hrs would be needed to run a small residential freezer for say 12 hours with an inverter when you (with out buying it and testing it) when you have no idea how man...

I would sure start with their kWh average and go from there. Divide storage capacity by kWh and this will give a rough estimation of insulation qualities.
My MONSTER 800 lb 20 CF VestFrost can chill to 0F in a 90F ambient on 90 amp hours at 12 volts per 24 hours. Newer models are most efficient.
Vacuum panel insulation is the key but hoboy the cost of construction is hideous.
Thanks MEXICOWANDERER
I would think 90 amp hours in 24 hours is pretty good. I'm looking at a 5 cu ft partly because smaller freezers the annual kWh were almost as high. Sorry but guess I don't understand how insulation quality would help in this calculation. I'm thinking the smaller the freezer the lower the insulation quality but that might not be right. Now if I knew what they estimated they estimated your annual KWH was maybe I could come up with a factor since you know your 24 hour needs on the 20 Cu ft. Since your is 20 cu ft & mine is 5 or only 25% as large do you think I'd be close saying I only us 25% of 90 in 24 hours? Probably not but probably closer than I am now. :B Thanks Mr WANDERER
