You run it during the middle of the day, say,,, between 1 and 3 in the afternoon and turn it off. The batteries are topped off, your freezer is at zero degrees and there's enough battery to easily handle your needs till tomorrow at 1.
I've said it before, if I was starting from scratch, designing a vessel using the latest technology I'd give the concept a go. That means changing everything and starting from scratch. Even with that I'd be monitoring amps all the time and trying to save a bit of battery power here and there. Personally I have other things to do. A good generator in a box is really quiet. No silent by a long shot but when you're on deck in the afternoon you can't hear it. That's the key, run it in the middle of the afternoon and be done with it for the day. On days when you move, the main engine can top your batteries off and that day you don't run the generator.
Our Kiss wind generator is used quite a bit. It can never keep up with our usage but if we have tradewinds all day it cuts down the generator usage by 50%.
One of the things that many don't catch on to before they cruise full time is that when you're making a passage of a couple of days or more, it's impossible to have solar panels keep up with all your needs and you need to either tow a water generator or run the engine or something to keep your electronics going.,,,, Or,,, you have to be so energy aware and use so little energy that you don't have any fun.
The best system for me would be to have all of them. Solar, wind and also a diesel generator.
At least that's my take on it.
