Ok, I bought 3 of these solar panels:
I want to charge a deep cycle 101 amp hour, group 27, 12V deep cycle RV battery with it.
With a 120 watt array (3 X 40 watt panels), how fast would it charge the battery in direct sunlight?
Do I hook up the panels in series or parallel? I know one is better than the other.
Will the built in 7 amp controller be adequate? Or is there a device I can attach that will allow me to monitor the battery and simplify it by just displaying a capacity bar like your cellphone does.
Help, me confuse by electricity thing.
