I just went to Home Depot & bought #8 copper cable & made my own. It was a little tough getting the #8 into the lugs on the controller. I had a longer run than I should have due to the mounting location of the controller. I just got mine up & running today but I think I have my needs covered with this kit. You could buy a 100W kit and make a tilting frame from PVC & put the controller close to the batteries. My kit came with 20' of cable for going from panels to controller.
