    <p>I believe Rapid Shutdown was mostly a solution looking for a
      problem.   The only way I see this becoming &quot;reasonable&quot; is to
      present &quot;grievances&quot; to the Code Making Panel WITH a solution for
      their consideration.  Based on experience from being part of an
      outreach program that taught approximately 10k firefighters over
      four years, I have asked that they add to the Directory, the
      language that states what type of solar electric system is on site
      (Microinverter, dc optimizer, string, multimode, grid isolated) so
      that First Responders don&#39;t have to guess.  I realize this is
      different than MLPE, but it targets the person who Rapid Shutdown
      came into being for, and that was the First Responder.   Chris<br>

                            RS on a DC array doesn&#39;t necessarily reduce
                            fire risk within the array, it still has the
                            potential to reduce severity and spread.
                            Nothing is going to prevent all fires. I get

                                            these systems have exhibited
                                            good to excellent

                                            my opinion, what we need is
                                            some additional innovation
                                            and competition in the MLPE
                                            space. Reliability is
                                            clearly a key factor, but
                                            there is no denying that
                                            MLPE has added safety
                                            benefits among other
                                            benefits. And if you do
                                            enough volume and set up
                                            your business for efficiency
                                            (standardization of product
                                            offerings), MLPE isn&#39;t much
                                            more expensive. It becomes a
                                            negligible cost relative to
                                            the benefit. The value
                                            proposition is easy to
                                            convey. There are limits to
                                            this, but for the majority
                                            of residential and small
                                            commercial installations,
                                            MLPE has become the de facto
                                            standard around here. String
                                            inverters are dinos, and
                                            replacing 8-12 year old
                                            transformer based inverters
                                            is many times more annoying
                                            than some MLPE swaps. I will
                                            admit that the roofs around
                                            here are pretty easy to
                                            walk, so that is a factor

                                            <div>Regarding rapid

                                              don&#39;t know if they were
                                              never installed properly
                                              or disabled/bypassed due
                                              to failure. It seemed
                                              suspicious to me at the
                                              time. I remember that it
                                              made me wonder what good
                                              is a rapid shutdown device

                                              That&#39;s another argument
