Super Basic Solar Upgrade

Really sounds to me like you have a handle on it- it's not that complicated and what you plan will work, well.
Basic kits most will use poly-crystalline panels which will charge your batteries. Basic kits will use an PWM controller which will charge your batteries correctly.
Many vendors for simple basic 2 panel kits under $250. Complete; panels (2)100 watt panels, mounts, wiring, connectors and controller.

Better Mono-crystalline panels generate more power, but at additional cost. Better efficiency in delivery using MPPT controllers (desirable) but again adds cost. Buying 'top shelf' unfortunately, price increase is a lot more than the 10-15% efficiency gain. Does offer better efficiency/charging- but price reflects. Buying basic does not require doing again though room to 'upgrade' should you want.

Snipped... All I want is to install two solar panels with a charge controller to provide charging capability to my existing flooded lead acid batteries...

I want to use the factory wiring that exists in the camper. The controller location is prewired with access behind a cabinet panel. I know the wiring is going to be minimal and won't carry the current efficiently. The plug on the roof is like the type you see on battery chargers. One step at a time...That obviously will work with adding SAE plug to panel wires, however most of the kits include 10ga wire to get from panels to controller.

Here are my questions:

Can I add a solar controller and panels that will charge my batts without worrying about any ill effects to the converter being affected? YES- Does the solar back-feeding the converter cause problems? NO. Both questions- solar charge controller (& other charge source) read and react to battery not other charge source.

Where is the best site....? Well not the best but CA Travelers compiled list of threads/installs within forum and what others have done (not all TC)

Just my 2¢
