D ) If you plan to do consumption metering:
• Make sure you have two split-core consumption metering CTs (order
CT-200-SPLIT).
• Check that there is enough space in the load center to install CTs.
Do not install the CTs in a panel where they exceed 75% of the wiring
space of any cross-sectional area within the load center.
E ) Decide how to connect the IQ Envoy to the Internet: Use Wi-Fi, an Enphase Mobile Connect modem, or Ethernet. Then, make sure you have
the following optional items, if needed:
• Enphase Mobile Connect modem [order CELLMODEM-01 (3G) or
CELLMODEM-03 (4G)]
• Ethernet over power line communication (PLC) bridge with Ethernet
cables (order EPLC-01)
• Ethernet cable: 802.3, Cat5E or Cat6, unshielded twisted pair (UTP).
Do not use shielded twisted pair (STP) cable.
F ) Create a paper installation map to record device serial numbers and
positions in the array. You will scan this map later using Installer Toolkit and your mobile device.
• Peel the removable serial number label from each device and affix it
to the respective location on the paper installation map.
• Write the IQ Envoy serial number on the paper installation map. Later,
you will need to enter this number in Installer Toolkit. You can type it
in manually or scan the label on the inside of the IQ Combiner door.
• Always keep a copy of the installation map for your records and to
upload to Enlighten later.

G ) Note that installation of the Combiner has two parts.
To ensure successful device detection, complete Part 2 after installing any Enphase IQ Microinverters and/or Enphase IQ Battery(ies).
Note: If needed, you can find an installation map at the back of the
Enphase IQ 6 and IQ 6+ Microinverter Quick Install Guide.
3 Remove an Unused Circuit Breaker (optional)
INSTALLATION — Part 1
You can complete Installation Part 1 before or after installing Enphase
Microinverters and/or Batteries.
1 Choose a location for the IQ Combiner
A ) Install the IQ Combiner in a readily accessible location. The best practice is to install at least four feet (1.2 meters) off the ground. However,
never install below three feet (0.9 meters) off the ground.
B ) Consider the dimensions of the IQ Combiner, easy access, box height,
and length of cable when selecting the location. Do not block the
vents. The IQ Combiner is rainproof but not watertight.
NOTE: You must mount the Combiner within 15 degrees of vertical.
The combiner includes three 20 A, 2-pole circuit breakers for combining
inputs and one single-pole 5A breaker for the 5A AC outlet. If required by
local jurisdiction, you can remove unused 2-pole breaker(s) and install a
blanking plate. Every IQ Combiner comes with a blanking plate with screws.
To downsize breakers, see our Technical Brief on the subject.
If you do not need to remove circuit breaker(s), skip this step.
Loosen these
screws
A ) Use a straight blade screwdriver to
completely loosen the busbar side of
the Line 1 and Line 2 terminal blocks
(grey).
B ) Remove the load wire(s), if any, on the
breaker you want to remove.
C ) Loosen the busbar lug(s) of only the
breaker you want to remove.
2 Prepare the IQ Combiner
A ) If needed, reposition the mounting feet. You can adjust each of the
four mounting feet to several different positions. Adjust as desired for
the mounting location.
B ) Open the enclosure door. Pinch the top of the hinge rod using a
needle-nosed pliers. Slide the door up and away to remove it. Set the
door aside for later reattachment.
Warning! The IQ Combiner has a pre-installed heat shield
attached to the enclosure door. Do not remove the heat
shield.
C ) Mount the IQ Combiner on a vertical surface, using supplied washers
to protect the feet.
D ) Remove the clear plastic deadfront and keep the screws and washers
in a safe place (for example, inside the removed enclosure door).
E ) Locate and remove the Spare Parts and XA-SLOT bags.
D ) Release the DIN rail locking tabs of all
breakers.
E ) Rock the breaker/busbar assembly to
the left to release it from the DIN rail,
and remove the breaker.
F ) Rock the breakers back to the right so
they are seated back on the DIN Rail.
G ) Lock all of the breaker DIN rail locking
tabs.
H ) Tighten the busbar side of the
Line 1 and Line 2 terminal blocks (grey)
to 14 in-lbs (1.6 Nm).
I ) Verify that all busbar connections are
tight.
Locking tabs
J ) Position the blanking plate onto the dead front
over the location of the removed breaker.
K ) Use a screwdriver and the two provided
screws to secure the plate into place.
Note: If needed, you can request a cover for
the 5A AC outlet from enphase.com/en-us/
support/contact.

A ) A label on the outside of the IQ Combiner indicates the best location to
make a hole or holes to accept conduit fittings. Locate this label.
Best Practice: Use a stepped drill bit for making the conduit holes. Using
a hole saw may crack the plastic housing. As an alternative, use a sharp
chassis punch with caution. Drill only at the label location. Do not drill a
hole in any other location on the IQ Combiner.
Note: The label template has three holes, but most applications
require only two.
B ) Use the provided label as a template for typical conduit placement. The
center of the holes on the label are marked with a “+” .
C ) Use a snap punch or other type of center punch to prevent the drill from
wandering. Drill a pilot hole with a smaller drill before using a step drill
bit.
D ) Remove the label after drilling.
E ) Use only UL-listed rain-tight or wet location hubs for wire entry into the
enclosure.
5 Wire the Output Connections
6 Wire Inputs from the AC Branch Circuits
A ) Use conductors sized per local code requirements (output lug is rated
for 14 to 4 AWG copper conductors for combined output) taking into
consideration the voltage drop/rise and upstream breaker or fuse.
The combiner comes with three 20A circuit breakers (16A continuous) to
which you must wire the device AC branch circuits.
A ) Use copper conductors sized to meet local code requirements and
voltage drop/rise considerations: 14 to 6 AWG copper for branch inputs.
B ) Bring in the wires from each AC branch circuit.
B ) The two DIN rail terminal blocks above the circuit breakers are the
output connections. Install L1 into the lower terminal block and L2
into the upper terminal block.
C ) Torque to 14 in-lbs (1.6 Nm).
Note: Enphase IQ 6 and IQ 6+ Microinverters use a two-wire system and
do not use a Neutral. The IQ Envoy still requires a Neutral from the load
center.
D ) Connect the neutral (white) to the neutral busbar.
E ) Connect the ground (green or green/yellow) to the “Ground” busbar
and torque to 45 in-lbs (5 Nm).
WIRING REFERENCE
The following lists tightening torque, allowable wire size, and type for
field-wiring terminals:
• 20 in-lbs tightening torque for circuit breaker connections
• 14 in-lbs tightening torque for combined output connections
• 45 in-lbs tightening torque for large neutral and ground busbar screws
(1/0-14 AWG)
• 20 in-lbs tightening torque for small neutral and ground busbar screws
(6-14 AWG)
• 14 to 6 AWG for branch inputs
• 14 to 4 AWG for combined output
• Wire type: 75°C or higher copper conductors, rated for wet locations
C ) Connect the ground (green or green/yellow) to the ground busbar.
Torque to 45 in-lbs (5 Nm).
D ) If an AC Battery branch circuit is installed, connect the neutral (white)
from that circuit to the neutral busbar. Torque to 45 in-lbs (5 Nm).
E ) Pass the L1 conductors from each PV branch circuit through the production CT in the same direction as the arrow on the side of the CT.
Note: Do not pass conductors from AC Battery branch circuits
through the production CT. This will distort production readings.
F ) Connect L1 and L2 (usually one black and one red) from each AC branch
circuit (PV and/or battery) to the circuit breakers.
G ) Torque to 20 in-lbs (2.4 Nm).

7 Install CTs for Consumption Metering (optional)
The IQ Envoy inside the IQ Combiner is pre-wired at the terminal blocks for power and production metering connections. One solid-core current transformer (CT) is
provided for production metering. You can install two optional split-core CTs to provide consumption metering. To do this, you must create a protected route using
conduit for the CT wires from the main load center to the IQ Envoy. If you need to extend the wires, refer to the Enphase IQ Envoy Installation and Operation Manual
at: enphase.com/support.
Note: Because of variance in load center design and main power feed, there may not always be enough space to install consumption metering CTs.
A) Make sure that the main load center wires are de-energized until you
have secured the CT wires in the terminal blocks.
DANGER!
Risk of electric shock. Always de-energize the load center
before beginning wiring.
B) Before running the CT wires through the conduit, use colored tape to
mark one of the CTs and the free end of its wires.
C) For the marked CT, connect the white wire to the upper “C1” terminal
and the blue wire to the lower “C1” terminal.
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.
D) For the unmarked CT, connect the white wire to the upper “C2” terminal
and the blue wire to the lower “C2” terminal.
E) Tighten all connections to 5 in-lbs.
F) 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).
G) 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).
From IQ Combiner
Load Center
Notes: It is important to match CT and sense voltage phases. To properly
measure power and energy, CT inputs must align with the respective
voltage inputs. Be sure to consistently identify and match the two AC
lines at two points: the main load center feed and the Envoy. Wire colors
(typically black and red) may not always consistently identify Lines 1 and
2. If in doubt, use a multimeter to check.

b 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
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) in the IQ Combiner 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.
g
Inoperable IQ Envoy and no AC to branch
If a single branch of microinverters is not producing and the IQ Envoy LEDs are off,
do the following:
Using a multi-meter set to AC, refer to the figure below and test for the following
values:
• Test point C to test point E. The result should be around 120 VAC.
• Test point C to test point F. The result should be around 120 VAC.
• Test point C to test point G. The result should be around 120 VAC.
• Test point C to test point H. The result should be around 120 VAC.
If not, there may be a problem with the wiring from the panel.
c 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 utility.
Next, check the breaker and wiring, starting at the load center.
• If all of 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 seated. 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.
G
H
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
remains off or lights solid amber, see Troubleshooting in the Enphase Mobile
LED
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.
