Well I postponed the roof coating until after this camping season. Installed the 2 100w panels and got everything wired up. It came with #10 from panels to controller. The distance from controller to batteries was a little farther than I thought so I ran #8 wire to the batteries. This evening when I got done the sun was setting. No direct sun on the panels and it read 6.5a @ the batteries. Will check tomorrow in full sun. Gotta love Az it was 83* today. I was breaking a sweat on the roof.
