I don't know if it makes any difference, but this involves an inverter, charge controller, and power distribution panel for a solar PV sysem.
As far as I can tell, according to the NEC, there is no minimum height for these components. I understand that there is a maximum height limit, but I'm not really worried about that.
But, according to 110.26, it also must have "working clearance." However, that is only necessary if it is for any equipment that may require examination, adjustment servicing, or maintenance while energized.
So I am wondering, is this PV inverter, charge controller, and power distribution panel subject to NEC 110.26 "working clearance" or not? There are breakers for the PV components, including the charge controller, in the inverter, as well as the required disconnects for the PV panels independent of the inverter.
Also, and connected to this question, does the NEC require clearance underneath the main breaker panel? The main panel has been placed in an enclosure, flush with the front of the panel, but underneath it there is open space where I could possibly put these PV components, if it is allowed.
Also, I understand that it is probably frowned upon to have the components so low, I'm just wondering if the NEC would allow it.
