Re: Repowering with an electric engine?
200AH * 48V is 9600 watts. Assuming a 100% efficient charging system you would need about 10 hours of noon-level directly sunlight. Here in the PNW that would be about 2 days.
1000W is a lot of panels. I don't know where I could put those on my 29' sailboat without ruining it.
It would be a bit of a pain but if you had 7 panels up each rail and 3-4 across the back, that would be 1700-1800 watts, about 6 hours best, Just have tofigure an easy way of setting/ removing/ storing them.
