The situation: We have two tractors (a lawn tractor and a medium JD with a loader and backhoe for farm-y things) and three ATVs that we leave at hunting camp. Since we go there about 5-6 times a year, they're often OK, but as you can imagine, batteries don't like it. It's standard operating procedure to just plug them all in when we get there.
I need two solar chargers - one for the barn/tractor, and one for the garage/ATVs/lawn tractor. The one for the barn will charge one battery, about the size of a standard car battery. The garage will charge 4 ATV type batteries. The garage and barn are about 100 yards apart, so one big one wouldn't be practical.
For the most part, a maintainer should do the trick, but it would be nice if it makes enough amperage to actually do some charging if needed. The farm is in a valley, so there isn't a ton of direct sun until about 10am-3pm, but often plenty of ambient light. I'm just thinking if we have a long overcast or snowy stretch, they might fall below the voltage threshold of where a maintainer could provide enough juice.
Thoughts?
