<p>Ray, I spent a bit of time today with a person who inspects for
several state renewable energy programs and to summarize, this
person said the opposite of what you said, and finish saying
"seems pretty clear cut". We did review three sections of 690,
and one from 705. I pointed out that these are not controlled
conductors as I interpret them but they should have been
defined. I did not see any earlier posts regarding this, so I
apologize for the redundancy. <br>

<p>This has been discussed to death in previous Wrench strings.
Just to cut to the chase:</p>
<p>please review NEC 2017, Figure 690.1(b) Note:(2). <i>The PV
system disconnect in these diagrams separates the PV system
from all other systems.</i><i><br>
</i></p>
<p>The inverter, charge controller, batteries etc are no longer
part of article 690, and are not subject to its requirements.
Look at articles 705, 706, and 480 for guidance for those <u><i>other
systems</i></u>.<br>

<pre class="moz-quote-pre" wrap="">Hi Chris,
A few times and my back-up with a schneider system is their rapid
shutdown. In the end the inspector comes around and realizes there is
little gain for an offgrid ground mounted array for fireman. You do have to
educate them and if they are insistent on being a bonehead, install the RS
for the inspection and then use the box for the next one or sell it.
After almost 30 years offgrid the last thing I want is something that can
fault out the solar or worse when I am away. Networks can be the enemy at
times. Less is more offgrid in my opinion.

<pre class="moz-quote-pre" wrap="">I got involved in a long discussion on Rapid Shutdown compliance for
battery multimode, grid interconnect inverters that have a ground
mounted array. At one point, ground mounted array was not supposed to
be subject to Rapid Shutdown unless there were dc conductors on the
building. NEC 2017 seems to say it is if conductors are 3' in or on
buildings. The intent of Rapid Shutdown was supposed to protect fire
fighters from exposure to high dc voltage when the array was on a roof.
Every code cycle it morphs into something a little different. Has
anyone had to confront this situation, and was this type of project
subject to Rapid Shutdown? Thanks in advance for any clarity on this.
Chris
