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.
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.
