IQ Envoy Installation and Operation
Extend Consumption CT Leads, If Needed
If needed, an electrician may extend the leads of the consumption CTs using the following guidance:
WARNING!
To extend the CT leads, the electrician must use appropriately rated, 1 814 AWG, twisted pair wire and install it in accordance with all applicable local electrical codes and the
National Electrical Code (NEC; NFPA 70 ).
The electrician may add as much as three ohms round trip resistance to the consumption CT or up to 1.5 ohms per wire. For reference, using NEC chapter 9 table 8 resistances, the following maximum lengths at 75°
C by gauge are:
•
57 .6 meters ( 1 8 9 feet) of 1 8AWG 7 strand Cu = 1 .
5 ohms
•
91 .
7 meters ( 301 feet) of 1 6AWG 7 strand Cu = 1 .
5 ohms
•
14 8.
4 meters ( 47 8 feet) of 14 AWG 7 strand Cu = 1 .
5 ohms
NOTE : In the NEC standard, chapter 9 table 8 resistance figures may not be appropriate for all geographies or installation conditions. A licensed electrician should determine the wire gauge and type to obtain a maximum round trip resistance of three ohms.
Select wire that is Code type, NRTL certified, and rated for voltage and temperature for the specific application. Mechanically protect the wires in a Code type, NRTL certified conduit or raceway. Use NRTL certified connectors for splices and insulated splices from one another and from the raceway, conduit, or junction box, if metallic.
Buried wires must be NRTL certified for direct burial and follow the Code for installation. Do not bury splices unless in a NRTL certified junction box rated for the application, and use an NRTL certified moisture resistant connection method.
4. Energize and Update the IQ Envoy
a. Close the terminal block door, and secure it with the screw. b. Turn on the circuit feeding the IQ Envoy. c. On the Envoy, if the AP Mode LED is not lit, press the AP Mode button. d. On your mobile device, go to Settings and join the Wi-Fi network “Envoy_nnnnnn” (where “nnnnnn” represents the final six digits of the IQ Envoy serial number). e. The app informs you if the software on the Envoy is not the latest version by displaying the Envoy
Software Update message. If the app displays this message, follow the on-screen instructions to update the Envoy.
WARNING!
Do not remove power from the IQ Envoy during the update. f. For a short period ( 5 10 minutes), you must keep your mobile device near the Envoy. Follow the onscreen instructions while the update takes place.
The update may take up to 20 minutes. The Envoy reboots several times during the update and the LEDs light up in varied sequences until the update is complete.
Once the update is finished and the PV system is installed, the Envoy is ready for Installation Part 2.
All four LEDs flash amber during boot up (approximately 3 minutes). When boot up is complete, the Device
Communications LED flashes amber indicating that microinverters are not yet detected.
