I am new to this forum.. am not a boat person.. but I did find this forum while researching the Coleman Stirling Cooler...
I do have the Coleman unit.. and I might be of some help to some of you who are interested in the stirling coolers...
The first thing that I notice is that many of you seem to think that this thing cycles like a conventional refrigerator
It does NOT .. it uses the minimum amount of power that it needs to in order to keep the set temperature...
For mine.. set to cool 3.. (coldest cool but not freezing) it will settle in at about 700 mA... if you open it and put in warm items .. it will ramp
up and draw more current
until the set temperature is reached.. then slowly ramp
down and draw steady current
I have mine connected to an 100aH deep cycle battery
and 13v power supply... when we lost
power here in New Orleans
Gustav.. the cooler ran fine for over 48hrs on battery power alone!.. I was the only one in the area that had cold beer
on those days :-)
I am still learning
just how wonderful this cooler really is.. and highly recomend it .. I only wish that I could buy two or three more of them!
So, while it does draw an very small amount of power compared to conventional compressor
refrigerators.. it draws that amount of power continuously... that is a factor in sizing your solar
array to power this cooler..
all that said.. I am looking at getting about a 200w solar
array and increased battery capacity.. and I think that I can run my cooler from solar power alone.
