Step 6: Ground The Microinverters (If Required) - enphase M215-60-2LL-S23-IG Installation And Operation Manual

Step 6: Ground the Microinverters (if required)

This step is required only for M215-60-2LL-S22, S23, and S24. It is not required for M215-60-2LL-
S22-IG, S23-IG, or S24-IG.
Each M215-60-2LL-S22, S23, and S24 comes with a grounding cleat (wire connector) that can
accommodate a 6-8 AWG GEC (grounding electrode conductor). Check local requirements for allowable
grounding conductor sizes.
NOTE: Ground the system in accordance with all applicable local electrical codes and the
National Electrical Code (NEC), ANSI/NFPA 70.
NOTE: CSA has evaluated and approved the Wiley Electronics "WEEB" grounding
washers for use with the Enphase Microinverter. Compatible grounding washer part
numbers and installation guidelines are included in the
NOTE: The AC output neutral is not bonded to ground inside the microinverter.
a. Route a continuous GEC through each of the microinverters to the NEC-approved AC
grounding electrode.
b. You can ground the PV racking and PV module to this conductor using a listed wire
connector approved for the purpose.
c. Torque the 10/32 grounding cleat screw to 2 N m (20 to 25 in-lbs). Do not over torque.
NOTE: Using a power screwdriver to tighten the grounding clamp screw is not
recommended due to the risk of thread galling.
