QUICK INSTALL GUIDE
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 System 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 qualied 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 Envoy and IQ 6 and IQ 6+ Micros do not communicate with, and should not be used with, previous generation Enphase Microinvert-
ers and Envoys. Always use the Q Aggregator and other Q accessories with IQ 6 and/or IQ 6+ 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
•
Screwdrivers
•
Wire stripping tool
•
Torque wrench and sockets for mounting hardware
•
75° to 90° C-rated 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 ipped
for roof or block mount installs, and allows you to t 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.
