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
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 IQ8 Series
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 Enphase Installer App and connecting
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
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 modules installed in portrait
orientation, while the 2.0 meter and 2.3 meter are for landscape orientation.
IQ Cable options
Ordering options include:
Cable Model
Q-12-10-240
Q-12-17-240
Q-12-20-200
The cabling system is flexible enough to adapt to almost any solar design. To determine the cable type you need,
apply the following considerations:
•
You may need to transition between cable types when mixing PV modules in portrait and landscape
orientation. See the preceding table for available cable types.
•
To transition between cable types, install a Field Wireable Connector pair.
•
In situations where portrait modules are widely spaced, you may need to use landscape-spaced cables for
the portrait-oriented PV modules and create loops of excess cable, if needed.
WARNING: Do not form loops smaller than 12 cm (4.75 in) in diameter.
