I've been looking over the specs of the Enphase stuff and read about the grid failure-system shutdown test.
It seems like a reasonable test that should be preformed once in a while to insure that no PV power gets sent out on the grid during a power failure.


I wonder if the Enphase minis can be used off-the-grid, by tricking them
with a portable AC source? (Like an UPS(APC) or a gas generator)?
