[RE-wrenches] Interconnection with Generator

[Corey Shalanski]

Wrenches,

We frequently encounter residences with backup generators. The question
that arises: how should the PV system be interconnected?

I have searched the archives and found some good information about this
subject, but nothing definitive. I have fallen into the habit of broadly
proclaiming that the PV system *must* be interconnected on the "utility"
side of the transfer switch - in order to prevent backfeeding into the
generator and thereby eliminate unintentional equipment damage. Is this
concern justified? If so, should this be an absolute rule or would it
depend on the generator make/model?

Thanks for any insights.
