YOU CHANGED THE QUESTION !!!
Adding the CPAP changes the need somewhat. If your CPAP draws an average of 3 Amp for 8 hours, you are looking at an additional 24 AH per day.
You say you're mostly in sunny spots, so 200 watts of solar would still be enough.
You won't die if the CPAP dies in the middle of the night.
I'd stick with the same 200 watts solar, 2 GC's, and a 1000 watt gen (a Honda or Yamaha inverter please, not a noise maker). If I were to do any more, I'd use 4 GC's to carry through cloudy days.

I have a 1000 Honda inverter. "You won't die if the CPAP dies in the middle of the night." uh yes... my wife will kill me when I start snoring :lol: So a simple 200 watt system is what I would look for and increase to 4GC's
