<p>Another way to do this that I often use for Offgrid is to build a small slab that a battery van can get to on an<span style="background-color: #888888;"> outside wall</span> of the house. Pick a wall of the house that this will not be an eyesore.</p>
<p>Build up a 2 x6 wall with a removable top and side. In the summer, a fan ventilates it outdoors.</p>
<p>In places where it is cold, the wall into the crawlspace, from the new box, is open and the batteries are at the temperature of the crawlspace.</p>
<p>No bending or cramped conditions and easy to replace batteries. Easy access for fire people to shut down.</p>

<div>Thanks for the advice everyone. These would be sealed AGM batteries. The access issues are definitely food for thought.<br />

<p>Never laid on my stomach, I just have kneel pad I use for lots of stuff but it works good here too. I never get my face that close to the battery any way. Usually 2 to 3 ft is good.</p>

<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's systems care. This is a head banger & a major safety issue if something goes bad. If the batteries are 18-20" tall that only leaves anther 28-30" 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>
<p class="yiv2169959718MsoNormal"><span style="font-size: 14.0pt;">If it is WLA batteries it is the worst of situations.</span></p>
