•
Install the microinverter under the PV module to avoid direct exposure to rain, UV,
and other harmful weather events.
•
Always install the microinverter bracket side up for horizontal mount installations.
•
Do not mount the microinverter upside down.
•
Do not expose the AC or DC connectors (on the IQ Cable connection, PV module, or
microinverter) to rain or condensation before the connectors are mated.
C. Torque the mounting fasteners to the values shown. Do not over-torque.
•
6 mm mounting hardware: 5 N m
•
8 mm mounting hardware: 9 N m
•
When using a third-party manufacturer's mounting hardware, use the
manufacturer's recommended torque value
D. Connect the microinverter to the IQ Cable connector. Listen for a click as connectors
engage.
E. Connect the DC leads of each PV module to the DC input connector of the microinverter.
F. Re-mount the PV module above the microinverter.
G. Energize the AC branch circuit breaker and verify the operation of the replacement
microinverter by checking the status LED on the connector side of the microinverter.
H. Use the Enphase Installer App to retire the old microinverter serial number from the IQ
Gateway database. In Enphase Installer App, once connected to the IQ Gateway:
a. Tap "Devices & Array" > "IQ Microinverters & Array" > "IQ Microinverter Serial
Number".
b. Tap "RETIRE" to retire the old microinverter serial number from the IQ Gateway
database.
c. Add the new microinverter serial number to the gateway database by scanning the
barcode using Enphase Installer App and your device camera.
d. Tap "Devices & Array" > "IQ Microinverters & Array" > "ADD DEVICES". Scan the IQ8P
Microinverter's barcode and assign it to the array.
OR
a. Go to "Service" > "Request return and install replacement" > "Install Replacement".
Enter the original device serial number and replacement device serial number and
submit.
I.
Start the provisioning process for the newly added microinverter using Enphase Installer App
and by connecting Enphase Installer App to IQ Gateway in AP mode. You can then "Start
Provisioning Devices" through Enphase Installer App.
J. Ship the old microinverter to Enphase using the supplied return-shipping label.
Enphase IQ Cable planning and ordering
The IQ Cable is a continuous length of double-insulated, outdoor-rated cable with integrated
connectors for microinverters. These connectors are preinstalled along the IQ Cable at intervals to
accommodate varying PV module widths. The microinverters plug directly into the cable connectors.
Connector spacing options
IQ Cable is available in three connector spacing options. The gap between connectors on the cable
can be 1.3 meters, 2.0 meters, or 2.3 meters. The 1.3-meter spacing is best suited for connecting PV
