Can a solar panel charge a 12V battery?
Yes it does. It can accept up to a maximum of 100V in solar to charge 12V batteries. To charge 12V batteries it needs Vbat (12V) + 5V to begin charging and the solar must be Vbat +1V to keep charging. Those solar panels Voc are probably more than 24V so you should be fine! Kirby, Good day to you. Thank you for your assurance.
