MidNite Solar is working on a unit that they are calling the
"Translator" that will allow the Classic controllers to communicate
with other brands of system controllers like the MATE or the XW System
Control Panel. I don't know how far along in the development process
they are, but maybe boB can chime in to let us know.
The general purpose "Interpreter" has been preempted by a couple of
other communications methodologies that
should be much quicker to design. One is for the SMA products because
we are working with SMA on that one.
As far as for OB interoperability, we are trying to see if we can use
their new AXS interface to talk back and forth.
That might just work and ~shouldn't~ take too much time to get going.

Otherwise I agree with Ray that using a MidNite Classic 200 will allow
you to use 4 modules in series. The max output amps on the 200 at
48VDC is 76A, so that limits you to about 4kW (76A x 52VDC = 3952A),
but that will work fine with 16 of the 240W modules. You can of course
exceed this, but you may see some clipping on clear cold days around noon.

I second WIlliam's sentiment about having all equipment communicate
together, but Outback just ain't there. I know Midnite's stuff will
communicate with the universal MODBUS language, and is not that silly
proprietary stuff that Outback does. I don't see any reason not to
use Midnite Classic lites and go to 4 modules in series. The
customer will also appreciate the computer interface on MyMidnite,
much more than suffering through the "MATE" screen. Let the Outbacks
sell independently, and I think for 2012, that's as good as it gets.
The idea of AC coupling as others noted is also a decent option, but
when I last looked, it is much more expensive.
Charge controllers are much cheaper per watt than inverters for a 48
vdc battery.
