<p>Article 110.26 covering clearances in front of electrical
equipment applies. I worked on a couple like that, and I
didn't like it. Very hard to move the batteries, and Combined
with H2S, you are in what OSHA considers a confined hazardous
space. </p>
<p>Another way to use that crawl space is to build a trap door
access from the floor above. This can work really nicely, and
put the batteries right under the inverter without violating
article 110.26. I think I saw a system that either Allan
Sindelar or Windy Dankoff did like that. I've tried it a few
times, and everyone (customers and inspectors) was happy.
Here's a pic of some HUPs in a floor vault just below the
inverter:</p>

<p class="yiv2169959718MsoNormal"><span style="font-size:14.0pt;">I have
been confronted with this issue in the past taking over
other\u2019s systems care. This is a head banger & a major
safety issue if something goes bad. If the batteries are
18-20\u201d tall that only leaves anther 28-30\u201d between bottom
side of the floor joist & the top of the battery. Your
face is way too close to a battery esp. if there is an
issue to address.</span></p>
<p class="yiv2169959718MsoNormal"><span style="font-size:14.0pt;">The
installation is bent over back-heavy move situation. I am
assuming you have a dirt or gravel floor to move across?</span></p>
<p class="yiv2169959718MsoNormal"><span style="font-size:14.0pt;">It seems
like a good use of space up front but the reality of the
install plagues you down the road.</span></p>
