<p>For GT using Solar edge or Enphase, its not so hard to comply,
but If you are looking at off grid systems, it's not just
someone's opinion, its $1,000s of dollars extra to comply with
690.12. It also results in a system that is less reliable, which
is less safe off grid where lives depend on that power for heat,
light, refrigeration, and even breathing machines.</p>

<div>Regarding location - the 2014 version had very little to
say about the location of any rapid shutdown initiation
device; 2017 adds the requirement [690.12(C)] that RS
initiation devices for one- and two-family dwellings be
readily accessible (defined in Article 100), AND outside the
building. Seems reasonable for a device that is intended to
control energized conductors to make it more safe to enter a
building. </div>

<p>Thanks Darryl.</p>
<p>I guess I can add that I am in CA and so looked only at
the 2014. I also looked at the 2017 article. Man, I have
to say, my impression remains that really starting with
2008 the code has just gotten worse and worse when it
comes to PV, but that is just me.</p>
<p>Not really sure what might need to be "Outside readily
accessible". Is there something other than 690.12 that I
need to look at?</p>

As I recall, an inverter and it's integrated
DC disconnect need only be placed in an
accessible location. I am thinking of putting
an inverter high up on the wall inside a
garage. That would be OK vis-a-vis the
location of the disconnect (still accessible
for maintenance).<br>
<br>
If I do put the inverter high up on the wall,
I can limit my DC conductors to less that 10
feet total from the array and less that 5 feet
inside the garage.<br>
<br>
That means I get the exemption from the rapid
disconnect requirement, right?<br>
<br>
There is nothing in the Code linking the
accessibility of the DC disconnect to the
exemption from rapid shutdown, right?<br>
