Step 3 – Position the Enphase Engage Cable
Many modules have a central stiffening brace. In these cases,
do
not position the connector and microinverter at the exact
center of the PV module, but position the cable so that
connectors do not conflict with the braces.
a. Lay the cabling along the route it will travel, positioning the connectors
so that they align with the PV modules.
b. Module widths vary by manufacturer. On the Engage Cable, connectors
are spaced at intervals to allow for the widest PV modules compatible
with Enphase Microinverters. If narrower modules are used, it may be
necessary to account for excess cable by adding a loop of cable at
suitable intervals.
Step 4 – Attach the Microinverters to the Racking
a. Mount the microinverters according to the microinverter
manual.
Ensure both that the microinverter does not interfere with the
PV module frames or stiffening brace, and that the drop cable from the
microinverter can easily reach the connector on the cable.
b. Ground the microinverters using either a continuous, unbroken
grounding conductor or approved grounding washers. Follow the
methods described in the
