Hi, I am planing to design electric solar panel system for my roof. solar panel will charge batteries and batteries will supply electricity to home devices. system will charge battery vary fast in sunny days and it will take long time to charge battery in cloudy days.
Battery may be damage when it will overcharge I want to prevent overcharging When one battery is fully charged, switch over to the next battery, cloudy or sunny day.
How to stop charging when the batteries are fully charged in solar panel ?
