We have a 51' Hudson
Force, so I have plenty of room for it and lots of batteries already, but I was wondering what the power draw in the tropics for this unit will be. (amp hours you are actually seeing used in the carribean).
I am fully aware that the top loading units are more efficient but am looking for feedback on this specific unit.
I have one of these units on a power boat
(not my sail boat). In the tropics you can estimate it will run 80% of the time or more. It is not water
cooled so it has to exchange heat with the surrounding cabin
air. Unless you put it in an air conditioned space it will run nearly 100% of the time during daylight hours. At night it might only run 65% of the time. So on 12V you should estimate about 65AH per day or maybe a bit more.
About the only way to help it run less is to make sure the heat exchanger
on the back of the unit is well ventilated. Possibly a cooling
fan added back there would reduce the AH a bit.
