Close and energize
IQ System Controller
WARNING! Connect the AC wires of the IQ Combiner and
IQ Batteries to the terminal lugs at the bottom of the
IQ System Controller load center on the left.
Do not connect the AC wires directly to the breakers.
The AC wires go into the terminal lugs, as shown on the label.
A. Before energizing, make sure that all IQ System Controller
wiring is complete.
WARNING! If not commissioning the system, you must
ensure that the DC switches on all IQ Batteries are turned
off to avoid the depletion of charge on the IQ Batteries.
B. Reconnect the dead front ground cable to the grounding
bar. Place the dead front using the five reserved screws.
Tighten the cover screws using a Phillips screwdriver.
WARNING! Risk of equipment damage. Ensure that no
conductors are pinched before placing the dead front.
WARNING! If either solar or storage circuits are not used
in an installation, their respective red and black colored
conductors should remain stowed in the clips on
the plastic frame supporting the panel board interior, and
their end caps should not be removed.
DANGER: Risk of electric shock. There are many potential
sources of voltage. Check any IQ Battery, PV, or other
sources for voltage.
WARNING! Risk of equipment damage. Do not wire the
IQ System Controller when it is energized.
If you work on an IQ6 or IQ7 Series retrofit system, and
C.
you plan to energize the IQ System Controller and connect
the PV without commissioning the system on the same day,
follow the sequence below:
a. Leave the IQ Combiner breaker in the load panel
where it was originally placed instead of connecting the
IQ Combiner L1 and L2 circuits to the terminal
lugs in the IQ System Controller. This way, your PV
systems can still be functional before commissioning.
b. Turn off the DC switches on all batteries.
c.
Open the IQ Battery breaker in the
IQ System Controller.

d. Close breakers in the following order:
1. Main breaker
2. Load breaker
WARNING! At commissioning, you must reconnect the
IQ Combiner L1 and L2 circuits back to the terminal lugs in the
IQ System Controller.
If you plan to commission the system, follow the instructions
D.
in the Enphase Installer App to provision and energize the
Enphase Energy System.
E. Once connected to the IQ Gateway, refer to the
Enphase Installer App help topics for more information.
F. If you do not see the IQ System Controller information in the
Enphase Installer App, check if the IQ Gateway AP mode
light is green. If not, press the AP mode button and follow
the instructions in the Enphase Installer App to connect the
phone to the IQ Gateway's Wi-Fi network.
G. Remember to close and secure the door of the
IQ System Controller before leaving the site.
