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.</span></p>

The general purpose "Interpreter" has been preempted by a couple
of other communications methodologies that<br>
should be much quicker to design. One is for the SMA products
because we are working with SMA on that one.<br>
<br>
As far as for OB interoperability, we are trying to see if we can
use their new AXS interface to talk back and forth.<br>
That might just work and ~shouldn't~ take too much time to get
going.<br>
</blockquote>
<br>
Actually now I'm not sure that is going to work because evidently
the AXS and Mate cannot both be used<br>
at the same time. Too bad the Mate 3 doesn't speak modbus.<br>
<br>
We will see if this is possible to do though.<br>

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.<o:p></o:p></span></p>

<p class="MsoNormal">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.<br>
The idea of AC coupling as others noted is also a decent
option, but when I last looked, it is much more
expensive.<br>
Charge controllers are much cheaper per watt than
inverters for a 48 vdc battery.<br>
