Today I called Morningstar about the overcharging issue when running both solar and battery charger. Steve gave, what I believe, is the perfect solution. Turns out the Morningstar Tristar 45 has a custom program option. Just change DIP switches for custom program and run the PC program called MSVIEW to set the absorption time for 1 minute. This means that each morning the controller will only dwell on absorption 1 minute before entering the Float stage. When we leave dock simply switch the DIP switches back and it reverts to the fixed (preprogrammed) mode with longer absorption phase. BTW, the custom setup wizard has hundreds of variables that can be set, but I just changed the one.
