Puzzeling thru a 12v to 24v solar upgrade
Currently have 400w of 12v panels feeding four 6v US Battery 2200's in series/parallel.The 12V battery output goes to a 1000w inverter dedicated to a single plug output for computers. There is a Blue ...

Your Tracer 4210AN CC allows an input voltage of 100 volts. You can safely put those 3 - 24 volt panels in parallel with no further modifications to your system.
The question really is how much WORK (and money) do you want to put into this system.
No on the volts!!!! That 325w panel will have a Voc (that's what you use for this) more like 46v (will get specs later to confirm exact figure) so 3 x 46 is 138 and that is at 25C. You have to allow some margin for when the voltage goes higher at times too.

No on your understanding of electricity. Putting those three panels together IN PARALLEL as I suggested would NOT result in over voltage at the CC. It would produce only 46 volts at the CC. The 138 volts you calculated is for the three IN SERIES, which I did NOT recommend.
Wow, I can't read! I screwed up there, sorry. :(
