5 watt foldable solar panel charger 36 99. Once we attach the charger with the battery voltage drops from the actual supply 14 2 v level to the discharged level of the battery. For example if the open circuit voltage of your solar panel is 20v and the battery to be charged is rated at 12v and if you connect the two directly would cause the panel voltage to drop to the battery voltage which would make things too inefficient. Mismatched solar panel application charging 6v batteries from 18v solar panels.

Normally solar panels are designed for a specific battery voltage applications. This solar charger has current and voltage regulation and also has over voltage cut off facilities. A 12v battery is normally recharged at 14 2 v or 2 40v per cell. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable.

It gives you approximately the identical current as though the solar panel was attached straight to the battery. 12 volt 35 amp hour sealed lead acid battery. Sunforce 50180 at 292 44. 5 watt foldable solar panel charger.
