Connecting Large Solar Panels
External charge controller
Using an existing solar panel(s) larger than 30W
Sometimes customers already own a larger solar panel than the 30W maximum Ghost Controls recommended. If you are interested in doing this, you must then properly connect the large solar panel directly to your battery. This application should ONLY be done with large automotive/marine deep cycle batteries and should not be connected to Ghost Controls 12V 7Ah batteries.
You should connect your large solar panel to asolar charge controller and then the solar charge controller is connected to the battery terminals. This solar charge controller is used to protect the battery from being overcharged and causing damage to the battery. You can search for "Solar Charge Controller" at many location including Amazon.
