To save my back I install watering systems with a flip cap for taking samples to check the SG on a refractometer.

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. 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: Ray Walters Remote Solar 303 505-8760 On 7/30/18 8:37 AM, Dana wrote: Safe working clearance is 6’-8”. 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. The installation is bent over back-heavy move situation. I am assuming you have a dirt or gravel floor to move across? It seems like a good use of space up front but the reality of the install plagues you down the road. If it is WLA batteries it is the worst of situations. Even if this is not inspected, please avoid this situation. ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc.

Are there any accessibility code issues with installing batteries in a crawl space? Does the NEC address this?
