I'm glad everyone is having so much fun with that pic, as scary as it
was. We could make a contest out of it: "How many code violations can
you find in this picture?"
and let Bill judge the answers. Believe me, there are more pictures,
where that came from.
Sorry, I do not know what those cylinders are. In a higher resolution
photo, they appear to have AC power cords coming out of them. Those are
HUP batteries under all the tools and extra parts. I hope they remember
to water the batteries.....

Any idea what the two silver cylinders in the upper left of the photo are
(sitting on top of the battery box)?
Hi Bill;
The 2014 NEC (coupled with rampant misinterpretation) is accelerating
an ever widening gap between those that have "code" and those that can't
afford it. On one side, US installers are forced to keep up with all
the code changes, AHJs that don't understand solar, and sky rocketing
insurance rates, all for the privilege to compete with the likes of
Solar City, only to reap the ever shrinking profit margins in the end.
On the opposite front of solar are an ever increasing army of Do It
Yourself Idiots (DIYI ?!) that are hooking inverters directly to large
battery banks with car jumper cables, or plugging GT inverters into the
grid with male/ male extension cords. (there really should be a law
against that)
So, apparently I work in the Purgatory of Solar, fixing imminently
dangerous situations, and not really caring so much lately about the
nuances of interpretation of the 2014 code.
For my money, 2008 code mixed with some 2011 as needed, seemed to be
plenty safe without throwing the baby out with the bath water.
I'm glad to see you bring some sanity back to the playing field. I
always appreciate your comments.
How about this Flying Cable, Dual Radian Install to stoke your code
interpreting abilities:
The more you look, the wronger it gets.....the buss block in the air on
the right carries several KW of PV array current.....
mmm, mmm, what's cookin'

PS, I already had the project in Mexico, before this thread came out......

This is not a change. Please help me understand the concern.

Interesting so does "require a tool" include taking a screw off the
cover plate of the combiner box, too?
What a game changer. I'm going to Mexico for my next project; I'll
actually enjoy even more being the sole AHJ on the project.

Readily accessible is now defined in the 2014 NEC. Installing
OCPD's underneath a module is a major faux paux, and I can't
imagine any AHJ thinking otherwise. Having to remove a module in
order to reset a breaker, what a drag.
"Capable of being reached quickly for operation, renewal or
inspection without requiring those concerned to use a tool, to
climb over, remove obstacle or other."

If that is the interpretation,
I don't see how the breakers are "readily accessible" in a
SolaDeck
mounted anywhere, regardless of whether it is under a
module. It
requires removal of four screws (using a tool) to access
the breakers
inside the enclosure. It's all up to the AHJ. It has not
been an issue
locally here. I can see how other jurisdictions may not
concur.
