I've been looking at buying a solar panel for my van. Whilst doing some research I've noticed that the wiring diagrams for the solar panel controllers show 3 connections. Unsurprisingly there's a solar panel input, an output to the battery for charging but was surprised by the 3rd which on the diagrams shows lights or an inverter connected to it. I have no current plans to use an inverter and as my 12V lights are already connected to the battery I presume I'd just leave this connection free. Anybody out there got any knowledge on this? If, in the future, I did decide to connect an inverter I presume the battery supplies the power to the 3rd connection when the solar panels aren't able to, is that correct? The controller prices also vary considerably. Is it worth spending the extra money on a more expensive controller and which type would you recommend?
