Three phase power [RE-wrenches]

[Drake Chamberlin, Quicksilver Electrical]

Hi Bill,

There shouldn't be a problem.  Several years ago, I fed 18 KW of solar power
into a similar system with three single phase Omnion inverters.  We were feeding
120 volts into each phase of a 120/208 V  3 phase system that was derived from a
277/480 V system.  I believe Ominion came out with a 3 phase grid tie inverter
after that.
