Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

Full Mosey,
I am going to follow the advice of Smkettner and keep the batts on Float for some time, so they would "wake up" and hopefully behave more like they should. Also, to watch the Tcomp and fine-tuning it with VRIM if necessary. Light use in daytime like charging laptop, running shaver, radio, etc with that much solar doesn't cause batts to cycle - voltage drops but they remain in Float.
IMHO, your batteries are healthy and performing per specs. I don't see any more wake-up being needed and I don't see where you did anything beyond fully charging before use as specified in the Shelf Life & Storage chart.
By no definition can it be said that you recovered/conditioned your bank.
What tells you that they are not performing?
Re the comment about nudging temp-comp Volts up to account for a difference between readings: I would hold off on that. What you are doing is using wet thinking. Wets are Volt whores, AGMs are Amp whores. Maybe that will get my point across. What is the Amp loss? :)
Also, direct your attention to having the Float Volts correct. If you nudge the temp-comp Volts, will you also be raising the Float Volts? That could cause longer term problems if you plan to use the solar during storage.
With solar Watts at 163% of bank AHs, you should be able to manage draws below average daily AH production. Will AH production usually be 110% of draws? I would like to know how many hours per day you are floating.
I have 159%, but my worst-case daily draws exceed my solar AHs. That is one reason that I have a genny.
HTH;
