Solar Kid or TS-MPPT? Which one?

So I am putting together a solar electric system that will use 3 270 watt panels to get 810 watts total and those panels will be used to charge a series parallel 24V/460AH bank of four 6 volt titan 105’s. I now need to make a decision on a charge controller. I have narrowed it down to either the Midnite Solar Kid or the Morning Star TS-MPPT-45 but would appreciate any other suggestions as well as any input on experiences using these two units.

I would prefer the TS-MPPT-45, just because, as one of our former moderators was fond of saying "Loads grow" and so do system, it would be nice to have the extra room to add some panels.

If they are in series +6-+6-+6-+6- = 24 volts @ 220 aamphours
If they are in series and parallel
+6-+6-
+< >- = 12 volt @ 440 amp hours
+6-+6-
At 12 volts, the array might fit on a Morning Star TS-MPPT-45 but you would be better off going to a 60 amp charge controller
At 24 volts, either would work x2 the voltage = 1/2 the amps
amps x volts =watts
watts/amps=volts
watts/volts=amps

- 440 AH * 29 volts charging * 0.77 panel+controller derating * 0.13 rate of charge = 1,277 Watt array
- 440 AH * 0.13 rate of charge = 57 Amps charging current (typical maximum rate of charge)
A 60 amp charge controller would certainly be justifiable if/when you decide to add a bit more to your array.-Bill

Looking at a 60 for future expansion though, I might consider a MN classic good for 96a.
