I also received this advertisement. Previously I had investigated
the smaller SMA transformerless inverters, and was told that this
type would not be allowed in the US until the 2011 code. Has the ban
been lifted?

I received an advertisement from a distributor that SMA is now
shipping 8, 9 and 10 KW transformerless inverters. Don't these
require double insulated PV wiring and no connection to ground on
the AC side? It's been too long since this subject last crossed my
desk and I want to refresh my memory on the specifics.
