The charge controller has a cut in of 13 volts and a cut out at 14.2 volts. I expected it to be in between those numbers. Not the battery volts(I understand 12.7 is full) but during the charge I expected it to be between those numbers. and thanks again for all the responses.
The low batteries can read 12.1 volts with solar on, but then with time in daylight that voltage will rise up past 13 to 14.2. Now you wait till voltage falls to 13 and it should start back up to 14.2.
You need an hydrometer to tell you the true state of those batteries, so you can tell if the solar is doing any good over time.
Right now the batteries are connected to the RV so they could be under a small load. That could be eating up any solar you are getting and nothing going to the batteries. Loads come first.
Too confusing using voltages, not enough info on what is really going on. Just stick an hydrometer in, and there will be no confusion.
