QUICK INSTALL GUIDE
A ) Download the Enphase Installer App version 3.X mobile app and open it to
log on to your Enphase Installer App account. With this app, you can con-
nect to the IQ Gateway to track system installation progress. To download,
go to https://enphase.com/installers/apps.
B) Check the box for the following items:
•
IQ Combiner 5 or 5C with IQ Gateway printed circuit board. The X-IQ-AM1-
240-5C also includes an LTE-M1 cell modem.
•
A pair of clamp CTs for consumption metering
•
One clamp CT for IQ Battery 5P monitoring
•
IQ Combiner 5/5C Quick Install Guide (this document)
C ) Make sure you have the following required items:
• For all Enphase Energy System Installations, a control signal cable is required
and must be purchased separately (for installations with IQ Battery 5P or IQ
System Controller 3), Enphase SKU for control cable: CTRL-SC3-NA-01.
•
Tools: Screwdriver, pliers, and torque wrench.
•
Up to four Eaton BR-style breakers (one for each PV branch circuit). Eaton
BR-style breakers are the only breakers you can use. You can install upto
60 A 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 distributed energy resources (DER) branch breaker ratings cannot
exceed 80 A. For IQ8 systems with IQ System Controller, use BRK-15A-2P-
240-B(or Eaton BR215B) for 15 A circuits and BRK-20A-2P-240-B(or Eaton
BR220B) for 20 A circuits to be compatible with the hold-down kit. The IQ
Gateway breaker should not exceed 15 A and is counted separately (total
90 A/95 A worth of breakers).
•
Up to two hold-down kits with screws for the breakers. Each hold-down kit
(X-IQ-NA-HD-125A) will allow the installation of up to two breakers located on the
same side of the busbar (only for IQ8 PV installations with IQ System Controller).
•
Overcurrent protection in the load center in accordance with NFPA
70, 705.12. and NEC 690
•
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 Gateway to the internet: Use Wi-Fi and
Enphase Mobile Connect, or Ethernet. Then, make sure you have
(Models: X-IQ-AM1-240-5C and X-IQ-AM1-240-5)
Installing the IQ Combiner 5 and IQ Combiner 5C
F ) Make note of the IQ Gateway serial number on the installation map. Later,
you will need to enter this number in Enphase Installer App. 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 5/5C has two parts: To ensure suc-
cessful device detection, complete Part 2 after installing any IQ Microinverter,
IQ Battery 5P, and/or IQ System Controller.

The IQ Combiner 5/5C combine up to four AC branch circuits
of IQ Series Microinverters and/or IQ Batteries. To install the IQ
Combiner 5/5C, read and follow all warnings and instructions
in this guide. Safety warnings are listed at the end of this guide.
If you do not fully understand any of the concepts, terminology,
or hazards outlined in these instructions, refer installation to a
qualied 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 5/5C have an outdoor-rated, NRTL-certied
NEMA type 3R enclosure containing an IQ Gateway, circuit
breakers, a pair of consumption metering CTs, an IQ Battery
5P metering CT, and wiring for IQ Gateway connections. The IQ
Combiner 5C includes a Mobile Connect LTE-M1 cell modem.
Use the IQ Combiner 5C for single-phase applications and to
support the AC connections needed for an Enphase residential
solar installation.
NOTE: The IQ Combiner 5/5C is compatible with IQ Battery
5P and IQ System Controller 3/3G. It is not compatible with IQ
Battery 3/10/3T/10T and IQ System Controller 1/2.
•
Enphase Mobile Connect (included with X-IQ-AM1-240-5C)
•
Ethernet cable: 802.3, Cat5E or Cat6, unshielded twisted pair (UTP). Do not use
shielded twisted pair (STP) cable.
When installing with an Enphase Energy System, both Enphase Mobile Connect and
additional internet connection (Wi-Fi or Ethernet) are required.
PREPARATION
NOTE: IQ Combiner 5/5C can be used for grid interactive (i.e., grid-tied) as well as
multi-mode (i.e., grid-forming) installations.
Warning! Risk of equipment damage. Instructions for wiring
grid-forming systems are different from grid-tied systems.
Follow specic wiring instructions as outlined herein to main-
tain warranty.
