Installing the Enphase Communications Kit 2
The Communications Kit 2 (SKU: COMMS-KIT-02) enables wired communication between IQ Gateway, IQ Battery 5P, and IQ System Controller 3/3G.
✓
The Communications Kit 2 must be installed when an IQ Battery 5P is being used with the IQ Gateway (standalone or integrated into an IQ
NOTE:
Combiner 4/4C/3/3C/3-ES/3C-ES) instead of an IQ Combiner 5/5C. The IQ Combiner 5/5C integrates the functionality of the Communications
Kit 2 and therefore does not require a standalone Communications Kit 2.
Read and follow all warnings and instructions in this guide. If you need help understanding 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 local codes and standards.

CONTENTS
The Communications Kit 2 enables the IQ Gateway to communicate with
the IQ Battery 5P and/or IQ System Controller 3/3G over the control
cable.
This kit contains:
• NEMA 3R enclosure with two DIN-rails mounted.
• Control adapter mounted on lower din rail.
• IQ Battery CT (leads must be wired to IQ Combiner terminals, as
shown in Section 6 of the
stalled on the aggregate IQ Battery Line 2 wire landing in IQ System
Controller 3 for multi-mode systems, IQ Combiner, or panel for
grid-interactive systems).
• One - USB Type-C to Type-A cable (40 cm/15 ¾ inch).
• Accessories bag including:
– Zip ties for wire management.
– Jumper (for shorting the IQ Gateway L2 and L3 power termi-
nals. Provided with this product for ease of system installation).
✓
For installation on sites containing the Envoy S Metered,
NOTE:
a 3-pin Wago that can fit into ports supporting 14 AWG wires
must be purchased separately.
– Two control headers pre-installed on the kit (one extra header
provided as a spare).
The USB cable connects the Communications Kit 2 adapter to the IQ

INSTALLATION
The installation section is divided into three sections.
1 ) Preparation
2 ) Product installation and wiring
3 ) Control (CTRL) wiring between system components and Commu-
nications Kit 2
DANGER! Risk of electric shock. All sources to equipment
being serviced must be disconnected external to the device.
In particular, the storage system may energize conductors, so
storage circuits must ALWAYS be isolated via a circuit breaker
or disconnected before working on any portion of the system.
Preparation
1
• The Communications Kit 2 enclosure should have access to a ground
bar.
• Identify your system design from the system wiring section below. The
control wiring installation varies based on the system design. You can
identify the Communications Kit wiring based on how the system will
be wired.
• Identify a vertical location where the enclosure can be mounted. Keep
in mind the dimensions of the enclosure when finding a location.
• It is recommended to power down the system before you begin to en-
sure safety while operating near electrical equipment and power wires.
• Ensure you have the following tools for the installation:
– Drill bit (required to drill holes for the conduit).
– Screwdrivers, pliers, and a torque wrench.
