Randen,

I have looked into islanding the Enphase microinverters. Supplying a 60 Hz, 240 V source to "trick" the inverters is not hard.

More difficult is balancing the load. It looks to me like a dump load is absolutely necessary to keep output voltage in limits. Not hard to do - a large resistive element (hot water tank, element from a 240 V oven, etc).

Harder is to do seamless switching between your true load and the dump load.

Thoughts?
