PREPARATION

A )  Download the Enphase Installer Toolkit version 3.X mobile app and open 

it to log on to your Enlighten account. With this app, you can connect to 

the IQ Envoy to track system installation progress. To download, go to 

enphase.com/toolkit

.

B)  Check the box for the following items:

• 

Enphase IQ Combiner 3C-ES or 3-ES with IQ Envoy printed circuit 

board. The X-IQ-AM1-240-3C-ES also includes an LTE-M1 cell modem.

• 

A pair of split-core consumption metering CTs

• 

Enphase IQ Combiner 3C-ES/3-ES Quick Install Guide

 (this document)

C )  Make sure you have the following 

required

 items:

• 

An Ensemble Communications Kit (COMMS-KIT-01 ) is not included. It is 

required for all Ensemble installations and must be purchased separately.

• 

Tools: screwdriver, pliers, and torque wrench.

• 

Up to four Eaton BR-style breakers (one for each DG branch circuit). 

Eaton BR-style breakers are the only breakers you can use. You can 

install 10A, 15A, 20A, 30A, 40A, 50A, or 60A breaker(s) in the IQ Combiner  

(order Enphase BRK-10A-2-240V, BRK-15A-2-240V, BRK-20A-2P-240V, 

Eaton BR210, Eaton BR215, Eaton BR220, Eaton BR230, Eaton BR240, 

Eaton BR250, and/or Eaton BR260 circuit breakers). The sum of all DER 

branch breaker ratings cannot exceed 80 A. The Envoy breaker should 

not exceed 10 A and is counted separately (total 90A worth of breakers).

• 

Overcurrent protection in the load center in accordance with NFPA  

70, §705.12.

• 

Suitable mounting hardware: use #8 (or larger) screws that are long 

enough to secure the unit to the vertical mounting surface

• 

Copper conductors rated for wet locations and sized to meet local 

code requirements and voltage drop/rise considerations. Wire sizes 

and torque values are listed on the door of the unit.

• 

UL-listed rain-tight conduit hubs for wire entry into the enclosure.

D )  For consumption metering, 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 (included with X-IQ-AM1-240-3C-ES) 

• 

Ethernet over power line communication (PLC) bridge with Ethernet 

cables (order EPLC-01). If you choose this option, you must install an 

Enphase accessory receptacle (order XA-PLUG-120-3) inside the IQ 

Combiner 3C-ES/3-ES.

(Model X-IQ-AM1-240-3C-ES and X-IQ-AM1-240-3-ES)

How It Works

IQ Envoy Display and Controls

Network Communications LED 

Green when IQ Envoy is connected  

to Enlighten.

AP Mode LED

Green when IQ Envoy’s AP Wi-Fi  

network is available.

AP Mode Button

Press to enable IQ Envoy’s AP Mode  

for connecting with a mobile device.  

Hold for 5 seconds to start WPS  

connection to a router. 

Power Production LED 

Green when microinverters are  

producing power.

Device Communications LED

Green when devices are  

communicating with IQ Envoy.

Device Scan Button

Press to start/stop 15 minute scan for  

devices over the power line.

Track system installation progress with the 

Enphase Installer Toolkit

 version 3.X 

mobile app. The LEDs on the IQ Envoy PCB (printed circuit board) are solid green 

when a function is enabled or performing as expected, flashing when an operation 

is in progress, or solid amber when troubleshooting with Installer Toolkit is required.

Installing the 

Enphase IQ Combiner 3C-ES 

and

 Enphase Combiner 3-ES

The Enphase IQ Combiner 3C-ES™  

and/or the IQ Combiner 3-ES combine up to  

four AC branch circuits of Enphase IQ  

Series Microinverters and/or Enphase  

Encharge™storage system batteries.  

To install the IQ Combiner 3C-ES or 3-ES, read  

and follow all warnings and instructions in this guide.  

Safety warnings are listed on the back of this guide.  

If you do not fully understand any of the concepts,  

terminology, or hazards outlined in these instructions, refer  

installation to a qualified electrician or installer. These instructions  

are not meant to be a complete explanation of a renewable energy system.  

All installations must comply with national and local electrical codes.  

Professional installation is recommended.
The IQ Combiner 3C-ES and 3-ES have an outdoor-rated, NRTL-certified  

NEMA type 3R enclosure containing an Enphase IQ Envoy™, circuit breakers,  

a pair of split-core consumption metering CTs, and wiring for IQ Envoy connections.  

The IQ Combiner 3C-ES includes a Enphase Mobile Connect™ LTE-M1  

cell modem. Use the IQ Combiner 3C-ES for single-phase applications and to support the  

AC connections needed for an Enphase residential solar installation.

Generator 

(reserved for future use*)

• 

Ethernet cable: 802.3, Cat5E or Cat6, unshielded twisted pair (UTP). 

Do not use shielded twisted pair (STP) cable. You must install a ferrite 

bead (we recommend Fair-Rite 0431167281) as close as possible to 

the IQ Envoy on the Ethernet cable.

F )   Make note of the IQ Envoy serial number on the 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 combiner door. Always 

keep a copy of the installation map for your records.

G )  

Note that installation of the IQ Combiner 3C-ES/3-ES has two parts: To 

ensure successful device detection, complete Part 2 after installing any 

Enphase IQ Microinverter, Enphase Encharge and/or Enphase Enpower.

IMPORTANT: 

The IQ Envoy in-

side the IQ Combiner is required 

to monitor performance of the IQ 

microinverters and to communi-

cate with Encharge and Enpower.
