Step 5: Ground the System
Each M215 Microinverter comes with a grounding clip that can accommodate a 6-8 AWG conductor.
Check local requirements for allowable grounding conductor sizes.
Ground the microinverter chassis as follows:
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 Racking Compatibility List.
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 crimp (compression) connection.
c. Torque the 10/32 grounding cleat screw to 2 N m (20 to 25 in-lbs) minimum. 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.
