I am installing a ground-mount system; generally these do not require rapid-shutdown (subject to 2017 NEC). However, the inverter will be located inside the house (in a utility room next to the main panel). This means there will be one or more wire pairs carrying up to 600vdc coming into the utility room. The wiring will be done underground in Sch80 PVC conduit. My main concern is reading an interpretation of the NEC that "conductors that extend greater than 10 ft from the array (outside) or more than 5 ft inside a building are required to be de-energized upon command of shutdown." It's the "5ft inside a building" that concerns me. Does this mean that the distance the wiring runs from where it penetrates the building envelope to where it enters the inverter must be 5ft or less ? Even if said wiring is contained in conduit ?
