Want to install solar, questions
We recently got our new 2017 Nexus Ghost and I had it pre wired for solar. Nexus provided (in a box) a Zamp 30 amp Digital Controller with the pre wire. My question is how many 100watt paneles well...

For now, if your DW can get by without the humidifier part of the CPAP, then it would draw less from the battery bank overnight.
A 100w panel will supply approx. 6.2 amps aimed at a full sum. How much you get with it flat on the roof depends on where you are and what time of year. A PWM controller needs some "margin" not to go over its 30a rating so you could run four 100w panels in parallel as a rule.
However you are not stuck with that controller. You don't have to get 100w panels unless there is a specific roof real estate issue. Do get a bigger battery bank now, and do lots more research on solar before buying anything so you have a better idea of your options.
You might be limited somewhat by the gauge of wire they used and how far the controller has to be from the battery bank, but even that can be worked around as needed if they didn't do it the best way.
