Hi, New to solar use. I have a BlueSolar controller Duo and 18v 100w solar panel.
I wanted one terminal to go to my car starting battery, as I only use the car once(ish) a week and the battery is always flat.
What do i need to add to the charger to enable me to plug and unplug the charger from my car without having to disconnect the solar panel from the charger etc which i understand is the order you are supposed to do it in.
