Here is how we added solar to our 19' TB. I used the factory prewire for the panels and captured the controller prewire inside up next to the inverter control. We are using a Blue Sky MPPT solar controller and so far it is all working great! I would prefer different batteries than the factory Interstate setup but I am going to use them up before we upgrade. The panels are 100W monocrystalline from Renogy. https://photos.app.goo.gl/hbFg1o3m8L4XC2cb7
