Q U I C K I N S T A L L G U I D E
Installing the
Enphase Q Aggregator
To install the Enphase Q Aggregator, read and follow all warnings and instructions in this Guide and in the
Enphase IQ Series Microinverter Installation and
Operation Manual
at
enphase.com/support
. 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.
IMPORTANT:
Enphase IQ Series Microinverters require the Q Cable and are not compatible with previous Enphase cabling. An IQ Envoy is required to
monitor performance of the IQ Microinverters. The Q Accessories work only with Enphase IQ Series Microinverters.
PREPARATION
A ) Check the box for the following items:
•
Enphase Q Aggregator
•
One bulkhead connector cap (Q-BA-CAP). You may need to order an
extra cap if you connect only one branch circuit to the aggregator.
•
Quick Install Guide
(this document)
B ) Check that you have these
required
items:
•
Enphase Q Aggregator(s) for multiple branch arrays
•
Drill with an appropriately sized hole saw for conduit entry
•
Wet/dry-rated conduit gland and conduit for home run entry
•
Screwdrivers
•
Wire stripping tool
•
Torque wrench and sockets for mounting hardware
•
75°C to 90°C copper conductors for connections between the Q
Aggregator and main PV breaker
•
Enphase disconnect tool
C ) Protect your system with lightning and/or surge suppression devices at
the sub or main panel.
D ) Protect the Q Aggregator with a maximum 60-amp over-current
protection device (OCPD).
E ) Size the AC wire gauge to account for voltage rise. Select the correct
wire size based on OCPD size and on the distance from the beginning
of the Enphase Q Cable to the breaker in the load center. Design for a
voltage rise total of less than 2% for the sections from the Enphase
Q Cable to the breaker in the load center. Refer to the Voltage Rise
Technical Brief at
enphase.com/support
for more information.
Best practice:
Use a Q Aggregator and Enphase Q Field Wireable
Connectors to center-feed each branch circuit to minimize voltage rise
in a fully-populated branch.
F ) Plan to install the Q Aggregator in a location that will be under the
modules when the array is complete.

Features
•
Lets you install systems up to 11.5 kW with only two line
conductors and a ground coming from the roof
•
Usable in any position up to 45 degrees from horizontal
(NEMA 3R, includes drain holes)
•
The aggregator bracket is ready to install on rail, can be flipped
for roof or block mount installs, and allows you to fit conduit
into either or both sides
How It Works
Use the Enphase Q Aggregator to bring together up to three
branches of microinverters, center feed branch connections,
or connect a remote part of the array using Enphase Q Field
Wireable Connectors.
