Not a problem, no offense was ever taken. First installer was apparently a linesman and an electrician was to look over the work and i guess didn't bother looking at how the panels were connected. Second installer was using a voltmeter checking amperage for loads and was wondering why he was getting constant 60 "amps". Took 4 readings and in the end his coworker told him the meter was on hertz. So got rid of those quickly. Currently on the 3rd installer.
I'm going to tell the current installer to stick to the 8x8 on MPPT 1 and 7 MPPT 2 and 7 MPPT 3.
Just to recap, you have 30 panels with 10 each facing East, South, and West. You have 3 MPPT inputs. Wouldn't the panels perform best if they are paired by direction? 10-10-10 (as already mentioned) If you had 3 east and 4 south on one string, wouldn't it tend to drag the whole string down to the lowest performing panel?
