I have the same setup and just posted on a separate thread. My charge controller also has a 'power' connection (picture of a lightbulb). I'm wondering if I need to connect the charge controller into another set of wires that power the lights etc? There are only two sets of wires in the storage compartment - I assume one is battery and the other is solar panel. Maybe I don't need to connect a third set of wires to the controller?
