Step 4: Attach The Microinverters To The Pv Racking - enphase M215 Installation And Operation Manual

Step 4: Attach the Microinverters to the PV Racking

a. Mark the approximate centers of each PV module on the PV racking.
b. Evaluate the location of the microinverter with respect to the PV module DC junction box or
any other obstructions.
c. Ensure that the microinverter does not interfere with the PV module frame or stiffening
braces.
d. Ensure that the connector from the microinverter can easily reach the connector on the
Engage Cable.
e. 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 module and the
top of the microinverter.
WARNING: You must install the M215 under the module, out of rain and sun. Do not
mount the microinverter in a position that allows long-term exposure to direct sunlight or
in a vertical orientation that allows water to collect in the DC connector recess.
f. Mount one microinverter at each
location using suitable hardware. The
indicator light on the underside of the
microinverter will be facing the roof.
NOTE: Installing the microinverter
black side up or vertically, with the
DC connectors facing up, is not
permitted.
g. Torque the microinverter fasteners to
the values shown. Do not over torque.

6 mm (1/4") mounting hardware:
5 N m (45 to 50 in-lbs) minimum

8 mm (5/16") mounting hardware:
9 N m (80 to 85 in-lbs) minimum
NOTE: Using a power screwdriver to tighten the mounting hardware is not recommended
due to the risk of thread galling.
