IQ Envoy Installation and Operation
Replacing an IQ Envoy
If problems remain after following the troubleshooting steps above, contact Enphase at enphase.com/en-us/support/contact .
If Enphase Customer Support authorizes an IQ Envoy replacement (RMA), perform the following steps.
DANGER!
Risk of electric shock. Risk of fire. Do not attempt to repair the IQ Envoy; it contains no user-serviceable parts. Tampering with or opening the IQ Envoy will void the warranty. If the IQ Envoy fails, contact Enphase Customer Support for assistance at enphase.com/en-us/support/contact .
•
Warranty void if cover removed.
•
Refer servicing to qualified personnel.
DANGER!
Risk of electrocution! When replacing the IQ Envoy, CTs must be installed with no current flowing in the sensed circuit. Always install CT wires in the terminal blocks before energizing the sensed circuit. Always de-energize the sensed circuit before disconnecting the CT leads from the terminal block.
DANGER!
Risk of electric shock. Risk of fire. Only qualified personnel should install or replace the Enphase IQ Envoy.
WARNING!
If the IQ Envoy you are replacing uses an Enphase cellular modem (Enphase
Mobile Connect), do NOT move the cellular modem to another installation site. This deactivates the modem.
C. Turn off the circuit breaker supplying IQ Envoy.
E. Disconnect the L 1 , L 2 , L 3 (if used) and Neutral wires from the old Envoy.
F. Disconnect the Ethernet cable (if used).
G. Turn off the circuit breaker supplying the microinverters.
H. Unlatch the split-core of the production CT (if used) before disconnecting. Once the CT is unlatched, remove it from the sensed wires.
I. Unlatch the split-core of the consumption CTs (if used) before disconnecting. Once the CTs are unlatched, remove them from the sensed wires.
J. When the replacement IQ Envoy arrives, install the IQ Envoy and provide power as described in
“ 2 . Provide a Power Connection” on page 13 .
K. Install the new production CT and consumption CTs (if used) as described in “ 3 . Install CTs for
Metering” on page 14 .

IQ Envoy Installation and Operation
L. Verify that the new IQ Envoy powers up.
BEST PRACTICE: When powered up and connected for the first time, the IQ Envoy may retrieve an automatic update from Enphase. This update may take up to 15 minutes. During the update the IQ Envoy LEDs flash green sequentially.
WARNING!
Risk of Equipment Damage. Do not remove power from the IQ Envoy if the IQ
Envoy LEDs are flashing green sequentially. This indicates that a software update is in progress.
CM. Connect the IQ Envoy to Enlighten as described in “ 7 . Connect to Enlighten” on page 1 8.
CC. Verify that the new IQ Envoy Network Communications LED lights green within five minutes.
If not, follow the network troubleshooting steps on page 3 6.
CE. If possible, log in to Enlighten and add the IQ Envoy to the Activation for this system by clicking
Add Another Envoy under the Envoy section.
CF. Verify that the new IQ Envoy 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 Envoy has communicated to the microinverters on the same day that the new replacement IQ Envoy is installed, the new IQ Envoy will be unable to discover the microinverters. Contact Enphase at enphase.com/en-us/support/contact for assistance in this situation.
CG. 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 Envoy closer to the load center.
CH. Contact Enphase Support at enphase.com/en-us/support/contact to have the new IQ Envoy added to your system and to retire the replaced IQ Envoy.
CI. Ship the old IQ Envoy to Enphase using the supplied RMA shipping label.
