Replace the Cover
A ) Make sure that the drain holes on the bottom of the Q Aggregator are
free from debris.
B ) Check the seal on all sides for trapped debris. Remove any debris, if
needed.
C ) Replace the cover on the Q Aggregator and torque screws to 1.1 N m
(9.7 in-lbs).
D ) Check that the Q Aggregator is properly sealed.
E ) Cap any unused branch circuit connections.
The Q Aggregator is now ready for branch circuit connections.
+
DANGER!
Never connect a single branch circuit to multiple branch
circuit connections on the Q Aggregator.

INSTALLATION
Plan the Location
A ) Select a location that will be under the modules when the array is
complete, but that will also be accessible for making connections later.
B ) Ensure that you can bring conduit into the Q Aggregator from the upper
left or right side where indicated by pilot hole indents.
BEST PRACTICE
: Lay out your cable runs before determining the
Q Aggregator location.
*
WARNING:
Ensure the conduit does not enter from an uphill
direction and that moisture does not enter the Aggregator.
Water
ingress will void the warranty for the Aggregator.
2
Drill a Hole for Conduit
A ) Prep conduit with an offset to approximate area and position the Q
Aggregator to double check your drill location.
B ) Remove the Q Aggregator cover and drill a hole for up conduit: Typical
openings are 2.2 cm, 2.8 cm, or 3.5 cm (0.885”, 1.115”, or 1.362”), but
check the conduit fittings you are using to verify size.
*
WARNING
: Take care not to damage the circuit board.
C ) Dump or blow out any debris from this drilling operation.

To remove a sealing cap or AC connector, you must use an
Enphase disconnect tool.
Each Q Aggregator includes one bulkhead connector cap. You can
purchase additional caps from your distributor.
Attach the Q Aggregator to the PV Rail
*
WARNINGS
:
• Install the Q Aggregator under the PV module to avoid direct exposure
to rain, UV, and other harmful weather events.
• Mount the Q Aggregator with adequate clearance from the roof
surface for rain and snow resistance.
• Always install the Q Aggregator with the label side up. Do not mount it
upside down. You can flip the bracket for roof or block mounting.
• When transitioning between rows, secure the cable to the nearest rail
to prevent cable damage.
A ) Install Q Aggregator on rail in a location that does not conflict with the
module frame and module mounting hardware. Allow a minimum of 1.9
cm (0.75“) between the roof and the Q Aggregator. Also allow 1.3 cm (0.50“)
between the back of the PV module and the top of the Q Aggregator.
B ) Install the Q Aggregator on the rail and mount loosely.
C ) Use a fittings rated for outdoor use to secure the conduit or Q cable to
the Q Aggregator.
D ) Provide an AC connection (home run) from the Enphase Q Aggregator
back to the electricity network connection using equipment and
practices as required by local jurisdictions.
E ) Tighten rail connections to 80 in-lbs (9 N m), and make sure that conduit
fittings are secured and water tight.
F ) Secure and check all connections.
Wire the Q Aggregator
A ) Pull the line conductors and ground up to the Q Aggregator.
B ) Strip the two line conductors (18 mm/0.7” strip length) using the guide
on the upper surface of the cage clamp style main lugs.
C ) Secure the conductors (12 AWG to 4 AWG max) in these lugs and make
sure that the orange handles are in the fully down position.
D ) Strip and bring the ground wire inside the Q Aggregator to the ground
lug. This ground lug passes through to outside for use in grounding the
rack and modules as needed.
E ) Secure racking ground to the ground lug.
F ) Torque the ground connections as follows:
• 14-10 AWG: 2.25 N m (20 in-lbs)
• 8 AWG: 2.82 N m (25 in-lbs)
• 6-4 AWG: 3.95 N m (35 in-lbs)
G ) Check your connections for soundness.
You have completed the wiring for up to three plug and play branch circuits
in your system.
5
Plan the Connections
A ) Plan for the following connections:
• One maximum 60 A home run: Pass the home run cable through wet/
dry-rated conduit gland, and secure in the cage clamp lugs to the terminal
connectors. Use standard home run conduit size (1/2, 3/4, or 1-inch).
• Up to three 20 A branch circuits: Three bulkhead mounted connectors
allow for the direct connection of the Q Cable.
• PV Array ground: The ground lug connection that passes through the
enclosure allows you to connect racking and module ground to the main
panel ground. The Aggregator contains no parts requiring a ground.
