Colleagues:
We have an 8 stack Outback system on a three phase off-grid
application. This works because the entire plant is using only two phases
of an open-delta wired generator system, the phases being on the opposite
end of the center tapped generator windings. We provide 120/240
feeds.

power.
Presently the max number of 3 phase you can stack is one using the master
slave, however this has changed I think.

Kent is correct, but you have to go a little further. We're all still
guessing that you've got Outback G series inverters and FM charge
controllers. If that's not the case, change some of the nouns below. In
any case, if the inverters are kept at default programming at some point

Nik,
Since you cannot operate 2 inverters in a 3 phase mode, they will need
to operate independently, so don't try to sync them. Operate both
independently. if the building is set up for 120/208 there is not 240
anyway. You could stack them in 120V synchronized and connected across
a single

Nik,
120/208 has a 120 degree phase angle between legs, same as three-phase
but you only have two legs. Check with Outback tech support, but I
believe the GTFX inverter can only be stacked in systems with 120/240
split phase (180 degrees between legs).
If there are no 208 loads, just unplu

Not syncing
Which inverters are you using? Do they share the same protected load
panel? I'm not aware of any GT capable battery based inverters which can
sync and sell across only two phases of 208, especially when they're
intended for 240v output per your post. Can you give us a little more
detail about w

Nik,
I haven't run into this myself, but...
I think what you have is not really split phase, but two phases, out of the
three available, from the three phase system in the main building. If that is
the case, those legs/phases are 120 electrical degrees apart, rather than the
180 degrees you would
Hi Gang,
I have a problem. We are installing a gridtie PV system with 2
battery-based inverters for 240V. The service coming in to the condo is
120/208 split-phase fed from 3-phase 208 in main building. The master
inverter pickups up L1 but the slave inverter will not sync. What am I
missing?
