Hi wrenches, I have been informed off list that my system is not a supported
configuration, that one phase can be paralelled, but the other two can not, one
only on each of the other legs. So unless Outback comes back with more info, I
was wrong. (mine still works, it was suggested I am very lucky)
I have used the Apollo in different configurations, stacked in single phase,
but I have not tried 3 phase stacks. Maybe you could conact Apollo.

Another method is to use the 120 volt VFX 3648, with one master and 14 slaves.
(15 total, 5 in paralled on each leg) Check this with Outback as the 3 phase
is different now than it was back in 2003. The three phase was the master
generated a square wave and each slave would use this to lag either 120 or 240
degrees. For standalone not grid tie. I did a multi inverter on standalone 3
phase.
Also a good source for this might be Julie Haugh <j...@greenhousepc.com>; She
has done a lot of work with Outbacks

Hi Daryl,
You might look at the new Outback 8kw 120/240v
I know that you can connect up to 10 in parallel, i don't know if you can do
it 3 phase however.
