Too cold in Norway, way too cold...
Which is why I left the place some 30 years ago, palm trees and sunshine in Florida
suits me better.
As for fridge for the 42' cat: What size is yer boxes and what is powering the compressor
and the batteries? Solar panels
, or generator
For a smaller system, I can highly recommend the Technautics Cool Blue.
Had it for 7 years and put 8000 hours on the system so far.
It has been very relible and uses very little power.
About 40 to 50 amps per day will run a 3 cubic feet freezer
and a 6 cubic feet fridge with temps at -10 C and +5 C.
If I crank the thermostat down to lowest setting the freezer will stay at
-21 C, but the power consumption
goes up to about 100 amp/hours per day, not really practical as my solar panels
pump out about 50 to 60 amp/hours on a good sunny day.
A big cat will of course have unlimited real estate to hang panels
and that may be the solution...
Say hello to Norway from the lost
