Had to Lower My Solar Float Voltage-Update
Updated 9 July Just a note for folks in a similar situation. My usual procedure in a normal summer here with my set-up with the Eco-Worthy controller (adjustable Absorb and adjustable Float ) is...

Yes, too long at high voltage after they are full. At least with Wets you can just add water if you don't get it right, but with AGMs you would have to be very careful.
Since you can't really keep track exactly, with AGMs you would have to under-set your voltages I guess, so they did not dry out. But then they would sulfate. Phooey on AGMs IMO! :)
Back to the OP, trying to figure out what to do, I see just after 11am, the Trimetric is showing AH hitting zero and about to rise into positive numbers (I have not bothered to reprogram the heat loss amount) while the solar is still in Bulk with voltage passing through 14 on the way to 14.8. SG is above 1.275 already so it looks like they will be at full SG by the time they get to 14.8 fairly soon now.
That would mean the Eco-Worthy dropping to Float right then with no Vabs time would work out just right.
Mex says make the Float 13.2 and if the weather stays the same for a while I won't have to do Float voltage resets every day after all. Too easy! (Yes I will still have to reset the Trimetric AH counter to zero when the batts reach full SG, which I will be when the solar goes from Bulk to Float) Today that will be at lunchtime, so that leaves eight more hours till I lose the sun on the panel behind some trees
