Technically, all you need to charge a 12v battery is a solar panel with a 12v rating. This can be any solar panel, although the bigger it's, the quicker your battery will charge.
Charging current: For this type of system, 0. 15C (100–150 A) is common, balancing efficiency and electrolyte health. Recharge time: After a deep cycle of 70% depth of discharge, recovery may take 12–14 hours, depending on available solar input.
