@ 4x4tour Thanks for your info. I looked at the link that you provided and the 8' foot MC cable may just be all I need. It's only going to run from the back of the roof of the hi-top van, through the crack of the back van doors, into the controller/batteries inside the back of the van. I don't want to even try to splice/cut anything. <br><br>How will 2 sets of MC cables (from the 2 solar panels) be able to connect to only 1 controller? I'm guessing the solar controller will have receptors that will connect to these MC cables, but what about for multiple cables? Afterwards, how will the controller connect to the actual batteries? Are there some sort of clips that extend from the controller that would clamp onto the positive/negative posts of the batteries?<br><br>Lastly, will most solar controllers have some sort of LCD readout display, so I can see the status of the charge, whether it's still charging or completed, etc?<br><br>
