Thanks for keeping this somewhat simple.Most of us weekdend warriors like me dont really need all that much solar ( or do we!). Got the led lites, dont need to use the micro, watch a movie or two with the 12v led tv and use water. I bought the solar panel kit from HF 45w. the controller goes to 14.5v I think it should at least give back what I took out of the batteries overnite? Do they sell a car battery charger that when we get home that can charge our 6v series batteries back up to 100%? Sorry to hijack the thread. Too much information!
