I've got a high-end customer who doesn't have the interest in knowing
the details of managing "manual" load shedding. He wants something
that works... period. At one point Gridpoint advertised this, but they
no longer make their products (I'm not sure they ever really had the
feature either).

system with two OB VFX 3648's powering an efficient home with a
"Smart"
homeowner who knows how to manage the loads in his house. Of course
that
could change in the future, but for the last three years it has
worked very
well. The XW and the Sunny Island systems were designed and
installed with
critical loads sub panels as recommended by SMA, OutBack, and
Xantrex. This
is the way to go for all but a handful of homeowners for obvious
reasons. I
have not worked with smart inverter systems that shed loads, but I
would
think that the technology is possible but not necessarily practical
or cost
effective when compared to a simple sub panel with critical loads.
