9. Verify that the new IQ Gateway powers up.
BEST PRACTICE: When powered up and connected for the first time, the IQ Gateway-
May retrieve an automatic upgrade from Enphase. This upgrade may take up to 15
minutes. During upgrade the IQ Gateway LEDs flash green sequentially.
WARNING! Risk of Equipment Damage. Do not remove power from the IQ Gateway if
the IQ Gateway LEDs are flashing green sequentially. This indicates that a software
upgrade is in progress.
10. Connect the IQ Gateway to Enlighten as described in "8. Connect to Enlighten" on page 19.
11. Verify that the new IQ Gateway Network Communications LED
five minutes. If not, follow the network troubleshooting steps on page 36.
12. If possible, log in to Enlighten and add the IQ Gateway to the Activation for this system
by clicking "Add Another Envoy" under the "Envoy" section.
13. Verify that the new IQ Gateway starts discovering microinverters within 20 minutes of
starting up. If necessary, use the Enlighten or Device Scan button to start a new device
scan during daylight hours. (See "Initiate a New Scan for Microinverters" on page 24.)
NOTE: If the old IQ Gateway has communicated to the microinverters on the same day
that the new replacement IQ Gateway is installed, the new IQ Gateway will be unable to
discover the microinverters. Contact Enphase at
assistance in this situation.
14. Assess the power line communications by running a Communication Check from Enlighten
or the Installer Toolkit. If the communication check shows poor power line communications,
relocate the IQ Gateway closer to the Switchboard.
15. Contact Enphase Support at enphase.com/global/support-request to have the new IQ
Gateway added to your system and to retire the replaced IQ Gateway.
Alternatively, you can use the Enphase Installer App. Open the app, select your system,
go to the Support tab, tap Replace Envoy, enter the details, and Submit.
