I went with the Harbor Freight 100w system.  Setup was super easy.  I went with this one for now because delivery of the expandable system from Renogy was several days away.  I will probably still get that one as well.  One thing I don't understand is the charge controller.  Even reading the manual, I don't understand.  It says hold this button and you can see the voltage, and click this button to raise or lower it, but it doesn't say what it should read and why you are raising or lowering the reading.  I can't find anything on  the net to explain what my settings should be or why I would raise or lower the voltage.  Just scratching my head.  I was able to set it up to my type of battery and that is about all at this point.
I would think that is a low voltage cutoff possibly.  If it falls below a certain voltage it will shutoff the power to the load.  Found a link https://newscrewdriver.com/2018/01/01/harbor-freight-63585-100-watt-solar-kit/ it seems to be voltage threshold for over charging and discharge.

Figured it out, Thanks Russ!!  Had to order another DC adapter cord for my CPAP, the one I got off of Amazon did not work, so I ordered the one from Resmed.  Should be here by Weds.  Anxious to see if it works as I hope it will.

Been having one of those, why didn't I do this sooner moments.  Two nights in a row with my CPAP running off of my Deep Cycle battery.  So awesome.  Solar charging the battery all day while I'm gone and nice and quiet at night.  WOW, Why didn't I do this 22 months ago!!!  Thanks for everyone's help and advice!!!
