<p>I would ask Fortress about the heights! </p>
<p>If this was offgrid and not inspected, I would have signage indicating there is a battery breaker/disco above this sign. If that breaker is tripped, I would think other things may be wrong and only qualified people should re-energize the breaker. That may need to be on the sign. If this is salt water, blowing water may have already done permanent damage. </p>
<p>The higher you go up to the ceiling, the harder it will be to keep the battery from getting too hot, especially in a garage. This is logged for battery warranty!</p>

<div dir="auto">That's problematic I think. I guess the next question would be, if I need to keep this breaker at 6'7", I don't see that being accessible be someone standing in front of it anyway without a portable ladder, so what height IS acceptable?
<div dir="auto"> </div>
<div dir="auto">Also, maybe I don't need to mount the whole battery above the flood level. Maybe just exposed live parts need to be that high. If that's the case, would that just be the tops?</div>

<div dir="auto">There is a 250A breaker located inside a compartment on the top of the unit. Keeping that reasonably accessible would be important. </div>

<div dir="auto">Also, just out of curiosity, how are you planning of getting these battery cabinets onto their 4' platform? Forklift? Ramp? </div>

<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">I am planning a battery backup system using Fortress 18.5kWh eVaults. Due to flood level requirements, these are going to need to be mounted about 48 inches above the garage floor on a shelf/platform. That puts the tops of the battery cabinets well above 6'7". But I believe that these do not fall under the working space requirements of NEC 110.26 since they are not likely to require maintenance. In fact, could these be mounted even higher, say way up near the 14' ceiling (subject to manufacturer spacing requirements)? </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;"> </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">Can anyone see any code problems with this approach, putting aside the practical problems with mounting heavy battery cabinets well above grade?</div>
