Sailboat with 500 amp-hours of battery capacity..
In Response To: Todd, curiosity about how many watts panels you rely upon for this.

() Sailboat - 40 watts
Powerboat with 400 amp-hours capacity 50 watts.
All it takes is enough to maintain charge. If the panels are only putting out 0.1 amps for 6 hours a day, the total charge over my 7 month layup is is around 120 amp hours. The Fall and Spring panel outputs are considerable more than 0.1 amps. Since I installed the panels, the batteries on both boats are always fully charged when I come on board.

- What winter storage?
- Only what's not built-in
- No, batteries kept aboard too but trickle charged
- I leave my batteries on board too...
- In the end, they'll lose less than 10-20% charge if left alone, disconnected from any wiring. .
