QUICK INSTALL GUIDE
CONTENTS
The Enphase Communications Kit 2 INT enables the IQ Gateway Metered
to communicate with the IQ Battery 5P. The device has a USB Type-C
port, two control cable ports, and a drain port.
The Communications Kit 2 INT includes the following accessories:
• One control header with termination resistor
• One control header without a resistor
• One USB Type-C to USB Type-A cable
• Zip-ties for cable management
• DIN rail adapters and screws
• Two spare control headers
The USB port connects the Communications Kit 2 INT to the IQ Gateway.
This enables communication between the device and the IQ Gateway.
The control headers must be installed on the control ports on the Com-
munications Kit 2 INT.
(Model: COMMS-KIT-INT-02)
Installing the Enphase Communications Kit 2 INT
The Enphase Communications Kit 2 INT (COMMS-KIT-INT-02) enables wired communication between IQ Gateway Metered and IQ Battery 5P using Control
(CTRL) cables.
Read and follow all warnings and instructions in this guide. Do not proceed if you do not fully understand any of the concepts, terminology, or hazards out-
lined in these instructions. These instructions are not meant to be a comprehensive guide to installing an IQ Battery 5P system. Use the IQ Battery 5P Quick
Install Guide along with this document to plan your installation. All installations must comply with local codes and standards.
Torque details of the control cable are given below:
DANGER! Risk of electric shock. All sources to equipment
being serviced must be disconnected external to the device.
Storage circuits must ALWAYS be isolated via a circuit breaker
or isolator switch before working on any part of the system.

INSTALLATION
Preparation
A ) Install the Communications Kit 2 INT in an IP3X or higher-rated en-
closure with adequate space for cable routing. It is recommended to
install both the IQ Gateway and the Communications Kit 2 INT in the
same enclosure.
B ) The enclosure should have access to an Earth terminal bar.
C ) Based on your installation design, identify if the Communications Kit 2
INT is a terminating node or a non-terminating node in the daisy chain of
devices connected via a control cable on the site. The installation proce-
dure varies accordingly, as described later in the document.
D ) Make sure the system is powered o before you begin the installation.
E ) Ensure that you have these tools and materials for the installation:
a. Torque terminal screwdrivers and wire stripper
b. Control cables
F ) Install the wired control headers on the unit. Refer to section 2, Wiring
the Communications Kit 2 INT.
G ) Connect the cable from the Earth bar to the PE port on the device.
H ) Connect the device to an IQ Gateway Metered with the USB cable
provided.
I ) Switch on the IQ Gateway Metered.
J ) The Communications Kit 2 INT can be installed in two ways. The box
ships with DIN rail adapters that can be connected to the device to
mount it on a DIN rail. The device can also be screwed into the back
wall of the enclosure using the screw points provided on extreme ends
on either side of the unit.

• Ensure that both ends of the CTRL cable twisted pair conductors are
inserted into the header, as shown above.
• Connect the drain wire to the drain terminal only at one end of a
CTRL cable. Do not connect drain wires at both ends of a CTRL cable.
Follow the guidance based on section 3, Control (CTRL) wiring between
system components.

Wiring the Communications Kit 2 INT
Strip the cable insulation as per the following image. Keep the termi-
nating resistor only on the devices that are on either end of the control
communication bus, and remove the resistor from all other devices.

Control (CTRL) wiring between system components
Control wiring guidance for installing IQ Battery 5P(s) with a Communications Kit 2 INT:
Refer to the following wiring sequences to understand the position of the header with termination resistor, wiring order, and drain wire termination location.
✓ NOTE: The total length of CTRL wiring across the system should not exceed 100 meters to ensure the system operates as per specications.
✓ NOTE: Ensure the following guidelines are followed to avoid failures during system commissioning:
• One header with termination resistor should be installed on the component located at each end of the control network.
• The drain wire should only be terminated on one end of control wiring between system components.
• It is recommended that the drain wire be terminated at the component from which the control wiring for the section is initiated.

• To ensure proper control (CTRL) cable connection with IQ Batteries,
follow the guidelines outlined below while connecting the cable to
the headers.
WARNING! Failure to follow wiring guidance will result in the
system being unable to detect devices, leading to commis-
sioning and operation failures.

Connecting to IQ Gateway software
The Communications Kit 2 INT needs IQ Gateway software version 8.2 or
higher to work with other Enphase Energy System components.
A ) Install the Enphase Installer App mobile application from iOS App
store or Android play store and log in to your Enphase account. With
this app, you can connect to the IQ Gateway to track system instal-
lation progress. You may also download the app from the Enphase
website at https://enphase.com/en-gb/installers/apps.
B ) Download the latest version of IQ Gateway software. To do so, go to
the Settings tab in the Enphase Installer App and tap the Update
Now button under IQ Gateway Software.
C ) After updating the IQ Gateway to version 8.2 or higher, scan the devic-
es to ensure they are identied as component of the Enphase Energy
System.
D ) Verify the devices are connected by navigating to:
Devices > IQ Battery > <serial number>
