I have more specific stats written down at home but in a different country at the moment. I'll give you some broad parameters here and can follow up with anything more specific this weekend when back home.
The system I tested this past summer was:
2 x 360 12 volt lithium mastervolt batteries
1 x mastervolt 3000 watt 150 amp combi
1 x 12k btu Cruisair
1 x vitrifrigp 2 drawer fridge freezer
Miscellaneous lights (anchor, floor etc)
temperature was 28-30 degrees
Air temperature was 30-32 degrees
Humidity was 85-90%
My test, done over several nights to get an average result was to cool / dry the starboard hull
of my 48 foot catamaran
first with genset on. At 10 pm genset would be turned off and would run items listed above through to 6 am off batteries alone.
I can't remember the exact average amps consumed but I think it was around 40-50 per hour. The result reflects the fact that the air con and fridge cycle off for long periods through the night, especially since the cabin
had been pre cooled.
With my 720 amp house bank, I had 75% of this or 540 amp available to use. My all night usage was never near this limit.
I was so impressed with the results that I have now added a third 360 lithium to the house, a second combi and am set up to run a second 12k btu air con unit in the port hull
now as well. On the port side the air con is just in one smaller cabin
so expect the required cycling will be even less. So far, after a few test nights, this has been fine.
