The following wiring connections and wire management are done by the installer:
•
Wiring from solar module to DC optimizer or AC microinverter
•
Wiring between solar module assemblies for DC optimizer systems
•
Wiring from the solar module assemblies to the AC trunk cable for AC microinverter systems
•
Wiring between rows of solar module assemblies
•
Home run cable routing within the solar array for DC optimizer systems
•
AC trunk cable routing for AC microinverter systems
•
Exit wiring from solar array to the roofing junction box
The work in this step must be completed by a licensed electrician.
The licensed electrician is responsible for the wiring from the junction box to the point of
interconnection, as well as laying the conduit and junction box on the roof. If required by the AHJ,
elevate the electrical conduit a few inches off the roof.
The AC or DC cable must transition to a properly sized cable in a junction box after it leaves the
solar array (Figure 73). Review the electrical design of the solar array.
Solar System Safety Labels
Apply labels per Table 3 (next page) and any applicable local codes. The MLPE and SolarWorld laminate will
have their own code and safety labels affixed.
