Getting my RV out for the season. Cheapo controller needs replaced. I have one panel on roof 165w and 18v. If I replace with a very large panel 250-400w but at up to 36v can I use a 100v 30a Victron controller and still get 12v out for my batteries? I have had one panel on the roof for over two years with no problem. Will the controller give me 12v output or do I need something else to go with it?
