<p>I second Jason's sentiments. We need to 'gently' but firmly push
back on all these extra code requirements, otherwise we'll be so
buried, we won't be able to stay in business. We've been under
attack from various factions since the 1980s, who have thrown
unreasonable requirements at us. Recall utilities requiring gold
plated disconnects or million dollar liability policies to grid
tie. Many folks are trying to politicize our industry, and we need
to let everyone know that energy independence is very American.
So is safe, affordable construction. </p>

style="font-family: arial, helvetica, sans-serif;">I have
had AHJs try to shoehorn solar panels into the mechanical
code before. I think your best bet is to argue the
applicability of the mechanical code entirely. Expressio
unius est exclusio alterius / The expression of one thing
implies the exclusion of others. If the IRC authors wanted
M1307.3 to apply to ESS, they would have said so in R328.</div>

</div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;">I would
go with something like:</div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;"><br>
</div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;">This
equipment is a UL 9540-listed energy storage
system, specifically tested to the UL 9540A standard. The
applicable section of the IRC is R328 (or 2023 IRC Section
327), not the mechanical code. Chapter 13 applies to
mechanical appliances such as HVAC equipment or combustion
devices—not sealed electrical ESS. This product does not
fall under the scope of M1301.1 and is not subject to
M1307.3.</div>
<br>
</div>
<div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;">If they
don't accept that, I would ask them to:</div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;"><br>
</div>
<div class="gmail_default"
style="font-family: arial, helvetica, sans-serif;">Point to
the section in M1301.1 that covers ESS. Explain why R328
doesn’t apply, despite being specifically titled “Energy
Storage Systems.”</div>

<div class="gmail_default"

another subject, I have been involved in another AHJ battle
regarding protection against vehicular traffic, and I have a
blog post on the subject coming out soon. Fortunately, the
next Florida Building Code draft mirrors the IRC, which
includes a clear schematic that clarifies the requirements. </div>

Seeking your suggestions and direction. My AHJ - after
acknowledging that the Enphase 5p battery has a floor
mount option - now insists that it must be 18-inches
above the garage floor unless I can produce something
that says it is "Flammable Vapor Ignition Resistant."<br>
<br>
We all know there is no open flame from an ESS and I
know the 9540A depicts a battery at 6-inches.<br>
<br>
Anybody run into this and have suggestions on what I
might show back to the AHJ?</div>
