Refrigeration Conversion Help
I will be cruising in the Caribbean for the next year or so and am building a new Freezer box for my 34' Seafarer (didnt have one before).
I was back and forth between a Frig-o-boat compressor/evaporator system and an Adler Barbour system - both run on 12v DC current. Both systems costs about $1500 + insulation, etc. This will be a Small Freezer only - about 3.5 Cubic Feet.
During my research I came across this :
EdgeStar 80 Quart 12 Volt DC Portable Fridge/Freezer - FP861
I found it online for about $600 all-in. My thinking is that I can remove the outer shell and build up the insulation to make it more efficient for the higher temps of the Caribbean. All for about $800 instead of close to $2000 with the other systems. It only pulls 80W! of power or, 5.7 amps DC - same as the Adler Barbour. Am I crazy or does this sound like the way to go...?
All my electronics are supported by 300W of Solar and a 400w wind turbine. I also have a genset. The Freezer will definitely be the largest power draw, but this seems like a no brainer to me. What am I missing?
