INSTALLATION — Part 1
You can complete Installation Part 1 before or after installing the PV system.
For steps 2 and 3, refer to the wiring diagram on the next page.
1 Choose a location for the IQ Envoy
WARNING: Risk of equipment damage. When installing the
IQ Envoy in an enclosure, choose area for installation where
ambient temperature does not exceed 46º C (115º F).
A ) Install the IQ Envoy near the main load center or PCC (point of common
coupling) and consider the length of the production CT leads (5 feet)
when choosing the location. Do not extend the leads of the production CT.
B ) Install the IQ Envoy in a protected dry space in an NRTL Certified, NEMA
type 3R (or better) enclosure with conduit attachment. Use an appropriately rated enclosure if hard wiring the IQ Envoy indoors.
NOTE: Metallic enclosures may impair Wi-Fi signal strength.
C ) Mount the Envoy:
• Mount it horizontally using the included DIN rail.
• To wall-mount, use two #8 screws and a screwdriver. Mount the DIN
rail first, then clip the IQ Envoy to the DIN rail.
2 Wire the IQ Envoy for Power and Metering
The IQ Envoy uses terminal blocks for power and metering connections. You
must install one solid-core current transformer (CT) for production metering.
Consumption monitoring is optional and requires that you order and install
two additional split-core CTs. Use a protected route in conduit for the CT
wires from the main load center to the IQ Envoy. The consumption CT leads
are 13 feet long. If you need to extend the leads, refer to the Enphase IQ
Envoy Installation and Operation Manual at: enphase.com/support. Do not
extend the leads of the production CT.
DANGER! Risk of electric shock. Always de-energize circuits before
wiring for power and CTs.
DANGER! Risk of electrocution! Do not install CTs when current is
flowing in the sensed circuit. Always install CT wires in the terminal
blocks before energizing the sensed circuit.
Note: When installing CTs, it is important to match CT and sense voltage phases. Be sure to consistently identify the two AC lines at three
points: the main load center feed, the Envoy, and the solar production
circuit breaker. Wire colors (typically black and red) may not always
consistently identify L1 and L2. If in doubt, use a multimeter to check.
Note: Because of variance in load center design and main power feed,
there may not always be enough space to install consumption metering
CTs. See our technical brief, Assessing a Site for Installing Consumption
CTs, at enphase.com/support.
A ) Wire the IQ Envoy for power
• Use a two-pole circuit breaker of up to 20 A (maximum) for the supply
wiring.
• Make sure supply wiring is 12-14 AWG copper rated at 75 degrees C or
better
• Use a screwdriver to loosen the screw on the terminal block door and
open the door.
• Flip open the terminal block door and wire the line and neutral conductors as shown: Connect Line 1 to L1, Line 2 to L2, and Neutral to N.
Tighten to 10.5 in-lbs.
B ) Install the CT for production metering
• Place the CT near L1 of the solar production circuit and make sure
the circuit is not energized (breaker OFF).
• Locate the arrow on the CT label.
• Connect the white wire to the left P1 terminal.
• Connect the blue wire to the right P1 terminal.
• Tighten all connections to 5 in-lbs.
• Pass the L1 wire through the CT in the same direction as the arrow
on the side of the CT on Line 1 (matching Envoy’s “L1” voltage
terminal) of the solar production circuit with the arrow pointing
toward the load (away from the solar array).
Note: Do not pass conductors from AC Battery branch circuits
through the production CT. This will distort production readings.
C ) Install CTs for consumption metering (optional)
• Make sure that the main load center wires are de-energized until
you have secured the CT wires in the terminal blocks.
• Before running the CT wires through the conduit, use colored tape
to mark one of the CTs and the free end of its wires.
• For the marked CT, connect the white wire to the upper “C1” terminal and the blue wire to the lower “C1” terminal.
• For the unmarked CT, connect the white wire to the upper “C2”
terminal and the blue wire to the lower “C2” terminal.
• Tighten all connections to 5 in-lbs.
• Clamp the marked CT on the load center feed wire Line 1 (matching the Envoy’s “L1” voltage terminal) with the CT arrow pointing
toward the load (away from the grid).
• Clamp the unmarked CT on the load center feed wire Line 2
(matching the Envoy’s “L2” voltage terminal) with the CT arrow
pointing toward the load (away from the grid).
3 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 on-screen 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
lights
solid amber, indicating that devices are not yet detected.

Device detection issues
If the Device Communications LED
lights solid amber, it may be a result
of low light levels. If there isn’t enough sunlight to power up the microinverters, they can’t communicate with the Envoy.
If there is sufficient daylight for the microinverters to power up, the issue
may be that the IQ Envoy is having difficulty communicating over the power
lines. To troubleshoot this issue:
• Check the Installer Toolkit mobile app to see which devices are not
communicating.
• Check that the circuit breaker(s) for the PV array are in the “ON” position.
• Verify that the PV modules are connected to the microinverters.
• Verify the PV module DC voltage is within the allowable range for the
microinverter.
Power production issues
If the Power Production LED
lights solid amber, check the Installer
Toolkit mobile app to see which microinverters are not producing:
• If none of the microinverters are producing power, there may be a
grid or wiring issue. First, verify that there is proper input voltage
and frequency from the grid. Next, check the breaker and wiring,
starting at the load center.
• If all the non-productive microinverters are on the same branch,
check the breaker and wiring starting at the junction box for the
affected branch.
• If only one or scattered microinverters are not producing power,
first check to see that the AC connectors are fully connected. Next,
check that each module is providing the required startup voltage
for the microinverter (22V). A PV module that is failing or that is
undersized may not generate enough power for AC conversion.
d
Internet connection issues
If you are using Wi-Fi and the Network Communications LED
remains
off:
• The WPS connection window may have timed out. Retry the connection steps.
• Make sure that the broadband router is operational by checking that
other devices at the site can access the network.
• Be aware that metal enclosures or obstructions impede wireless
communication.
• If you cannot see your router or access point in the list on the
Envoy, or cannot maintain a connection, it may be necessary to add
a wireless repeater to extend the network range.
If you are using Wi-Fi and the Network Communications LED lights solid
amber, make sure that the broadband router is connected to the Internet
by checking that other devices at the site can access the Internet.
If you are using the Enphase Mobile Connect modem and the Network
Communications LED remains off or lights solid amber, see Troubleshooting in the Enphase Mobile Connect Installation Guide.
For any connection method, you can troubleshoot network issues with the
Installer Toolkit mobile app by tapping the Network button, then Diagnostic Tools.
If you replace the broadband router, configure the IQ Envoy Wi-Fi settings
for the new Wireless Network Name (SSID) and password. Or use the
WPS function described in step 6.
