Islanding [RE-wrenches]

[Drake Chamberlin, Quicksilver Electrical]

I was asked today if two Trace SW inverters could keep each other
producing power when the utility was down.

This theoretically could only happen if the two were isolated together,
separated from the rest of the grid.  The grid at large would look like
a tremendous load to the inverters.

Say two inverters were feeding the same transformer.  If the line to the
transformer were disconnected, could two Trace SW inverters keep the
local grid alive?  Are there any safeguards that would prevent this?
