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. Phil ----------- "When we learn how to store electricity, we will cease being apes ourselves; until then we are tailless orangutans. You see, we should utilize natural forces and thus get all of our power. Sunshine is a form 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." -- Thomas Edison -- On Thu, Jul 28, 2011 at 12:23 AM, William Miller <[email protected]>wrote: > Friends: > > Is there any way to connect two SW series inverters to two phases of a > three phase generator?
