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.

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.

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

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
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.
