Hi William, Thank you. I am leaning towards the second option. Hopefully
I can draw it out and understand it first! Thank you again, Chris

I think we can do this. Each does have its own neutral, (we added one).
Outback didn't mention this possibility. It's definitely worth a shot.
We only have an one hour window to work on this in any one day do to the
operation of the facility. Thank you. Chris

We were asked to replace two failed Trace SW4048 inverters with two
Outback GT3048 inverters. Upon start up the slave inverter would not
connect. We did not realize that the building service is 208, 3 phase.
The bypass is 120/240 which the SW4048s could connect to without a
problem. Outback
Chris:
I am surprised that the SW inverters connected to this service. They may
not have been synced properly. Was there a ribbon cable between the two
inverters? Maybe this is why they failed...
Are there 240 VAC loads in the system? If not, you can configure the
inverters in parallel
Chris,
We had a problem similar to this in the Bahamas, only with a Radian
instead of an
FX series inverter. We used an Acme transformer, 3 ph 208 on one side,
single phase 120/240 on the other end. It was about $1200 for the
transformer. Acme is in Tennessee I believe and we worked with one of
Use a 208 - 240/120 transformer.

You could use a 120:120volt, with both the first and second inverters using the
same phase, but the xfmr secondary used to supply 120 volts out of phase from
the primary for the slave. Voila, auto-transformer 120:240 split phase power.
Downsides are the heavy loading all on one phase and
We had exactly this scenario at Dankoff Solar, to back up all the computer
loads in the business. The building was 120/208, and the two SW inverters would
sync to their respective phases, 120 degrees apart. The fun part was watching
them on a scope when you shut off grid power -- they would
