Hi BFL13,
Set the solar to the same float as the shore power. If the controller can't do that--then it is inadequate.

You could just float with solar only, too. I had no choice but to do that between 2009 and 2013.
What 0.2 volts? Instead of staying at 13.8 all day on just converter it gets to 14.5 or so depending on how much sun gets on it (highly variable where the RV is). It can take all of the daylight hours to get there so it is above 13.8 all day.
Seems easier just to disconnect the solar at home than fiddle with the controller settings.
