Enphase Iq Cable Planning And Ordering - enphase IQ8MC Installation And Operation Manual

•
For vertical mount, maintain > 30 cm (12 in) clearance from the edges of the PV module to protect the
microinverter from direct exposure to rain, UV, and other harmful weather events.
WARNING: Risk of equipment damage. Mount the microinverter under the PV module.
•
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 (1/4 in) mounting hardware: 5 N m (45 in-lbs. to 50 in-lbs.).
•
8 mm (5/16 in) mounting hardware: 9 N m (80 in-lbs. to 85 in-lbs.).
•
When using UL 2703 mounting hardware, use the manufacturer's recommended torque value.
D. If you are using bonding hardware, the old bonding hardware should be discarded, and new bonding hardware
must be used when installing the replacement microinverter.
E. Connect the microinverter to the IQ Cable connector. Listen for a click as connectors engage.
F. Connect the DC leads of each PV module to the DC input connector of the microinverter.
G. Re-mount the PV module above the microinverter.
H. 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.
I. Use the Enphase Installer App to retire the old microinverter serial number from the IQ Gateway database. In
the Enphase Installer App, after connected to the IQ Gateway:
Tap Devices & Array > IQ Microinverters & Array > IQ Microinverter Serial Number
a.
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 the
Enphase Installer App and your device camera.
Tap Devices & Array > IQ Microinverters & Array > ADD DEVICES. Scan the IQ8 Series
d.
Microinverter's barcode and assign it to the array.
OR
Go to Service > Request return and install replacement > Install Replacement. Enter the original
device serial number and replacement device serial number and submit.
J. Start the provisioning process for the newly added microinverter using the Enphase Installer App and by
connecting the Enphase Installer App to IQ Gateway in AP mode. You can then Start Provisioning Devices
through the Enphase Installer App.
K. 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 12 AWG, 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.
The cabling is compatible with a variety of PV racking systems. For a list of approved PV racking systems, refer to the PV
Racking Compatibility document on the Enphase website at
