Step 4 – Attach the Microinverters to the Racking
a. Mark the approximate centers of each PV module on the racking system.
b. Evaluate the location of the microinverter
with respect to the PV module junction
box or any other obstructions.
c. Ensure both that the micr
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
Drop cable.

WARNING : Allow a minimum of 1.9 cm (0.75 inches) between the roof and the bottom of
the microinverter. Also allow 1.3 cm (0.50 inches) between the back of the PV modul
and the top of the inverter. Do not mount the microinverter in a location that allows long
term exposure to direct sunlight (i.e., it should be covered by the PV module).
d. Ground the microinverters using either a continuous, unbroken grounding conductor
or approved grounding washers. If using grounding washers (e.g., WEEB) to ground
the microinverter chassis to the PV module racking, choose a grounding washer that
is approved for the racking manufacturer. Install one grounding washer per
microinverter. To
