Reply To: Charging a battery with a single panel

[dg77]

Thanks 12vman, I am after a no cost/very low cost solution. Was thinking this morning about the regulator in an old car? I guess there is one and it would be doing a similar thing when a car is running – charging but not overcharging the battery. Just wouldn’t have a function to turn off power to light if battery gets low, but it would only be used a few hours a night at most. Could it work?
