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: Do not mount the microinverter in a location that allows long-term exposure to
direct sunlight (i.e., the microinverter should be covered by the PV module).
f. With the silver side of the microinverter
facing up and the black side facing down,
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 is not recommended as
it may allow moisture to collect
between the cover and the body of the
microinverter. If installing the M215 at
an angle, check that this angle does
not allow for collection of water in the
recesses of the microinverter.
