Master and Slave?

[Photowhit]

I'm close to needing a couple Classics and could end up with 3 all with different configurations. (Seems I bought a big traction battery, then found a deal on a modular home)

So I have a 800Ahr 24V battery, and am installing 20 - 200watt panels (28V on 2 Classic(lites?") and 12(or more) 24V nominal, panels on an PWM controller, or anothe lite. I've been helping (and asking questions) on forums for years and have had 2 controllers working independently on the same battery bank,..but had anticipated that the Classic would incorperate a Master and slave situation. I have followed this forum some since I had decided the "Classic 150" was the way to go, so I have seen rumors. Is this in the works?

I can see with communication between them, having 12(3-4) - 200 watt on one classic, 8(4-3) - 200 watt on another classic and 12(3-4) 185watt on a 3rd. As I actually have too much array for the battery I worry a bit about over charging, though with I understand it's not likely with proper Asorb and Float settings,...

I could even break down and buy 48V traction battery (If I sold the cabin perhaps with the current array and 24V battery)

I guess I would just leave the CC handling the highest power with the Equalizing task?
