Why did they have 4 batteries? Might be a herring... But my boat had 2 with the factory setup from 2011 and the small panels wired as peter described.

If it wasn't for indoor storage I wouldn't have turned the batteries off. In the slip I could leave the lights on and not have to connect to shore power or worry.
