Re: the controller--
My "go to" video is Garrett Towne's (AMSolar) explanation on how to choose a solar controller. I've watched it at least a dozen times. Everything I'd write is in the video, so please watch his 10 minute presentation.
Note that if you do go with a Victron controller, the "SmartSolar" versions have the Bluetooth connectivity, the "BlueSolar" versions do not.
For your wire question--the 10ga wire I bought from AMSolar is more than sufficient for the voltage/current carrying capacity of my system (from panels to junction box). From the junction box to charge controller and charge controller to battery I use 4 ga. What is best for your system depends on all the usual factors (distance, voltage, current, etc).
Hang in there, Keith. There's a lot to learn! It took me many, many hours of studying, watching, and asking questions before I began to understand it.
