Geocell 2300 is not a polyurethane sealant as far as I can determine and as I
suggested ( read the label ) is compatible with asphalt shingles , it is a
tripolymer but not a polyurethane . It is definitely better than silicones and
Sikaflex . I have never found a polyurethane listed as compatibl
I need one, too - same model! Contact me off-list.

Tom,
"polyurethane tripolymer sealants while excellent sealants ARE NOT
COMPATIBLE WITH ASPHALT SHINGLES"
That's not accurate. Geocel 2300, a tri-polymer sealant, specifically lists
asphalt shingles as a compatible substrate.

Thanks Brian -- I think that covers both DC and AC sides then.
But the Mike Holt textbook I received taking Ryan Mayfield's (excellent)
class at NABCEP Denver last month specifically says "dc circuits" all
throughout the 690.12 analysis.my copy of NEC2014 does not specify DC
at all.
Did I mis
Dan. Great thoughts on the subject. I agree with the power shed idea but this
isn't feasible most of the time for me. I have been thinking about AC coupling
for off grid systems and the idea doesn't excite me. Thanks for your input.

The definition for "PV system" moved to Article 100 in 2014. I think it's
pretty clear that the PV system includes the inverter, if present, and the
inverter output circuits.

Hi Aaron, boB, Wrenches;
I think Aaron brings up a good point, and it's certainly confusing to me.
The boldface type heading of 690.12 is "Rapid Shutdown of PV Systems on
Buildings"
The body of the 690.12 text begins with "PV system *circuits* installed on
or in buildings shall."
