This should be possible. I have discussed what it might take to set
up a system like that in the Gambia, with wind generators. It would
take a control system with differential current sensors and other
features. The UL 1741 specifications would probably need to be
opened up on multiple direct grid tie inverters. There would be a
practical limit on the percentage of feed to the generator mini grid.
This being said, I've not received much encouragement with this
idea. There are a lot of factors to consider.
