What I do is completely fill the freezer part with canned beer.
The Ice beer works best because of the high alcohol content it doesn't
freeze and bust open. But, the thermostat cant' be set to the cold
position. About 1/4 the way to all the way cold works best. My freezer
contains 15 twelve ounce beers. I relpace them one at a time as I drink
them. I maybe drink six on a hot day. I cycle new beers from the fridge
section to the freezer section and add new ones to the fridge section as
I drink them. An admirable holding plate.

My box is very-well insulated and because of it my compressor usually
runs 20 minutes on 40 off in the summer and about 15 minutes on and
close to an hour off in the cooler months of winter. Let's call that
one-third of 24 hours for 8 hours total or 40 amp hours. The box
measures about 1.5 feet by 2 feet by 1.5 feet. For about 4.5 feet cubed.
It and everything else is run by two Evergreen 100 watt photovoltaic
arrays connected to a Sunsie charge controller. The fridge runs more in
the summer months but the days are longer too so the batteries stay
well-charged the year around.

You're getting down to brass tacks now. My main reason for a fridge
would be to chill beer. I might be out in the Gulf of Mexico and Keys
for a couple weeks at a time. My wife drinks mainly pop and juices,
lukewarm - she doesn't like chilled drinks. I don't care what temp my
water is, but I like my beer cold. I normally don't drink beer in
morning or high sun, but might hanker for a cold Coca-Cola in those
hours, which also comes in 12 ounce cans
I'm thinking for guys like me there is a BCAH calculation for
beer/coke amp hours. I just don't know what it is.
You weren't clear about cooling anything except beer in your reefer.
Let's say I want to spec out reefer cooling 6-8 12 ounce cans per day.
How would you recommend going about calculating BCAH, and sizing the
reefer to accomplish that?
Thanks.
