<font size="2"><font face="arial,helvetica,sans-serif">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.<br clear="all">

Friends:<br><br>
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).<br><br>
Any input is appreciated.<br><br>
Thanks,<br><br>
William<br>
