[RE-wrenches] Energy Storage and Working Spaces for Other Equipment

Mon Feb 1 12:43:22 EST 2021

Here’s the built out wall/cove/soffit of mine as well. Kind of hard to tell though, need to take a side view picture. Before and after expanding the battery bank. It’s about to get expanded again on the PV side and still is missing a piece of trim in the photos.

We either keep the battery cabinet shallow, or we put the battery cabinet to the side.   Just use some common sense, if you are having to lean awkwardly over or around something to get to the breakers, its probably a violation.

We have systems with two or three outback radians above blueplanet batteries and have not seen an issue. The BPE's are in an enclosed cabinet fire approved and protected from shock, putting batteries further away will create space issues. Since all of these components are required for the "system" to operate they are necessary.

>> I'm seeing a lot of pictures of LiPO battery systems and people are mounting equipment above them like load centers, inverters with disconnects, and other serviceable enclosures. Some of these battery systems are 24 inches deep or more. This seems to violate NEC 110.26 requirements for the other serviceable                   equipment, but the pictures are proudly displayed as models of success. Even slender Tesla Powerwalls stick out significantly when stacked 2 or 3 deep and would be more than 6 inches deeper than a standard load center. Sure, the battery cabinets make great places to rest tools while working, but does anyone else see this as problematic?
