William,
The SW Parallel Stacking Interface (SWI/PAR) was much more than just a
cable (like the Series Stacking Cable -SWI). it was a separate box,
like the Grid Tie Interface (GTI) unit was. It retailed for about $345.00
Good luck finding one.

For parallel, I believe a current balancing transformer was involved
besides the synchronization cable.
That's why it was more involved than just a cable. Since there can be a
few volts difference between
the 2 stacked SWs.

Friends:
I received an inquiry from a solar contractor looking for a PARALLEL
stacking cable for SW inverters. I have never laid eyes on such a
cable. Did they exist? Does anyone have one or a diagram?
Many thanks,
William Miller
