Phil:
Did the system you describe have the SWI stacking cable in place?
Thanks,
William

At my previous employment we had a pair of SW's in exactly this
configuration across a 120/208 three phase supply. Stacking on the SW's
wasn't so much about coordinating operation between the two as much as it
was the master of the moment giving a zero crossing and telling the other
to stay out of the way. When grid wasn't present, the inverters would
operate 180 degrees out of phase, 120/240 output. When grid was turned
on, the slave would drift 60 degrees to sync up with the incoming power,
and the two would operate as two legs of a 120/208 supply. Kinda fun to
watch on a scope.
If all your connected loads are 120V, you should be fine.

of energy, and the winds and the tides are manifestations of energy. Do
we use them? Oh, no! We burn up wood and coal, as renters burn up the
front fence for fuel. We live like squatters, not as if we owned the
property.
There must surely come a time when heat and power will be stored in
unlimited quantities in every community, all gathered by natural forces."

Friends:
Is there any way to connect two SW series inverters to two phases of a
three phase generator? It seems to me that one could connect three SW
inverters with the right stacking cable (or am I confusing Outback
inverters with the hub jumper set properly).
Any input is appreciated.
Thanks,
William
