15w Solar Panel with Charge Controller
This is a utility power source. It can be used for many things, such as a fence charger or light.
The charge controller protects the battery from overcharging. It includes 2 cables, one ten foot cable from the door to the charge controller. And a second cable that can be used from the charge controller to your battery.
The charge controller has a digital display to show you the battery's voltage. It also will disconnect the load if the battery gets too deeply discharged, protecting the battery from damage.
