<p class="MsoNormal">Dave \u2013 you may be referring to a product from Maxim Integrated to replace bypass diodes. I have not heard much recently about this, but it did sounds promising.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And related to MLPE continuing to be required due to 2017 NEC 690.12, I believe UL 3741 will be published within a few months. This will allow products (likely racking and certain module types) to be listed as a PV Hazard Control Array.
That listing will satisfy the Inside the Array Requirement 690.12 B(2)(1), thus avoiding the 80V limit of 690.12 B(2)(2).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I assume racking manufacturers will go after this listing (and pay the cost) as they can sell for a good markup as they can justify how much cost they will save by not requiring MLPE devices.<o:p></o:p></p>

<p class="MsoNormal">I was told at a training a couple years ago that there were going to be some modules coming out soon that had a microchip in the module junction box which would replace the diodes and effectively work as MLPE. I have not heard anything
about that recently though. Does anyone know what I am talking about? It seems that this would solve many of the issues associated with MLPE, but still be able to have the benefits.<o:p></o:p></p>

<p class="MsoNormal">Since I only work with off-grid systems, I find the 690.12 exception starting in NEC 2017 for ground-mounted systems with DC equipment in a separate structure intended only for PV components, is very useful for avoiding expensive, unneeded
RSS equipment. Many folks don't like the idea of a battery bank and buzzing equipment and fans in their dwelling anyway, so the "power shed" idea works well, and around here structures 120 square feet and under don't need building permits. I did see one system
pass with 3 PV modules on the roof of the power shed, though technically that's not part of the 690.12 exception.<o:p></o:p></p>
