voltages rising above those allowable by code. Should this situation arise, notify the local utility of the issue.
However, there is also the ability to adjust the upper shutdown voltage of the microinverters via the CP-GWY-100
gateway. Please contact a Chilicon Power representative for assistance.
Step 2: Position the Microinverter on the PV Racking and Loosely Secure
Attach the microinverter using the appropriate
MLPE mounting hardware for the PV racking
selected and loosely secure using either an
allen wrench or socket (depending on the
manufacturer). Keep loose enough such that
the microinverter can slide along the rail.
Note that the final cable segment often
connects to two microinverters, so the last
microinverter in a branch circuit will need to be
within 2 feet from the end of the trunk cable.
Position the micro such that it will lie under the
PV module with the chassis facing downward
and out of direct sunlight. Also, leave at least
0.6in (1.5cm) clearance between the roof and
the bottom of the microinverter; and at least
0.6 in (1.5cm) clearance between the back of
the PV module and the top of the microinverter.
For rail-less or ballast mount systems it is
possible to attach the microinverter directly to
the PV module frame using a suitable mount,
such as Unirac 8114M Mount.
Step 3: Complete the Installation Map
While the CP-100 gateway can identify the various microinverters connected to the system, it cannot locate their
position in the layout. Therefore, it is important to capture this information during installation using the layout
map generated during the design. Once a microinverter is associated with a module (or set of modules), remove
the serial number label located on the microinverter and place it at the corresponding location on the map.
Also, at this time draw a line connecting the panels to be paired if installing the CP-720 dual microinverter. This
map will be used later when constructing the physical layout in the monitoring software. It is advisable to keep
the original copy of the installation map for your records.
