L,
I'm surprised you actually believe the specs. Don't all manufactures error on the side of their interest? Wind Generators out put, Alternator output, refrigeration amps, etc. I don't know where or how they ended up with the energy cost. Was it cooling the box in an office with 75 degree air or outside in the shade with 90 degree air or on a boat on the cabin sole with 90 degreee air and 90 degree water? I noticed they have a 15 amp fues in line. I all makes me wonder. I don't know if the boater I've mentioned was off and didn't know her power consumption or if the Engel people are being overly optimistic. Personally, I tend to believe the real world experience.

That said, there are a lot of people that love the Engel and there are times I wish I would have considered putting in two instead of a big holding plate system. Then I could easily have shut one down when not needed.

ps Even with your "fast" tri it ain't fast when compared to a 747.
