I find the above statement hard to believe. 18 AH/day is 9 hours of
operation out of 24 for a duty cycle of .36. It was on 36% of the time. Our Engel
freezer, set to zero F, in the galley, used more like 50 AH/day and operated
almost continously in the summer.
I have used two Engel units for about two years, one as a refrigerator and
one as a freezer.
They pulled about two amps each when running. These were the 1.4 Cu/Ft units.
Early on I put an hour meter on one of them and made some guesses as to AH
used. My final conclusion was that both together used about 75 AH in the
summertime with ambient temps around 90F, somewhat less in winter with the ambients
around 70F.
Their main drawback for us was that the insulation is around one inch and
they were small, 1.4 Cu/Ft. They seem to be designed for use in a motor vehicle
with a plentiful supply of 12 to 24 volts where portability was important.
Our current units, called "Sundanzer" are made in Sweden by Electrolux
specifically for off-grid use. They are around 5 Cu/Ft, pull about 2 amps, and use
the same amount of AH because the insulation is 4.3 inches thick.
We love them but they are a bit large for most boats.
