Cover and energize the system
*
WARNING:
Before energizing, make sure that all IQ Batteries in the
system are properly installed and conductors terminated.
NOTE:
Check the box for updates on cover installation instructions.
A ) Check that the
field wiring compartment
cover(s) for all IQ Batteries in
the system are closed and secured.
+
DANGER:
Risk of electric shock
. Before continuing, check that IQ
Battery units are properly wired, and ground connection does not have a
L1 or L2 connection, as this introduces a safety hazard.
• Apply AC power to the IQ Battery circuits. Do NOT turn On the DC switch on
IQ Batteries.
• Using a voltmeter measure the IQ Battery chassis metal to ground (e.g.,
grounded conduit) and ensure there is no AC voltage source present. If
wiring is incorrect, a ground fault may exist, and the AC voltage may read
~120VAC. If voltage is present, DO NOT touch the chassis, and immediately
remove AC power from the IQ Battery circuits.
• Remove AC power to the IQ Battery circuits and correct the wiring.
*
WARNING:
Before commissioning, DC Switch on IQ Battery shall
not be turned on, unless instructed in Enphase Installer App. Turning DC
switch On before it is instructed in Enphase Installer App can damage
IQ Battery.
B ) Connect the AC power (branch circuit protection On) to IQ Battery and
commission the IQ Battery using Enphase Installer App with DC switch
in Off position. Wait for Envoy to update the IQ Battery firmware. Turn DC
switch On only after you see a message in Enphase Installer App asking
to turn it On.
*
WARNING:
After commissioning, always follow the sequence to supply
the AC power first and then turn the DC Switch On. The turn Off sequence for
AC power or DC Switch does not matter.
NOTE:
Do NOT leave the IQ Battery unit’s DC switch in the On position for
any extended period of time (such as overnight or for more than 24 hours)
unless IQ Battery is commissioned (communicating with Envoy), connected
to AC, and has passed functional testing and is operational. Leaving the DC
switch On without AC connection and communication with the system will
drain the battery and may cause damage to the battery cells such that they no
longer be able to charge. Damage resulting from this improper installation and
misuse is not covered under the product’s limited warranty.
C ) Place enclosure cover(s) over the battery(ies) as follows.
IQ Battery 3 (single-width battery cover)
• Pick up the IQ Battery 3 Battery cover, stand in front of the battery so that
the cover and battery are on a level, and slide the cover over the battery
so that the interior guides of the cover slide easily over the guides on the
battery unit.
• Check that the screw hole on top of the battery cover aligns with that on the
battery.
• Use the included screw to attach the cover to the battery. Tighten the screw
as needed.
IQ Battery 10 (triple-width battery cover)
• The IQ Battery 10 Battery cover in wide and may require two persons to
guide smoothly over the battery units.
• Pick up the IQ Battery 10 Battery cover, stand in front of the battery so that
the cover and battery are on a level, and slide the cover over the battery
so that the interior guides of the cover slide easily over the guides on the
battery units.
• Check that the screw holes on top of the battery cover align with those on
the batteries.
• Use the included screws to attach the cover to the batteries. Tighten the
screws as needed.

IQ Battery 10 without cover
A ) Use the Enphase Installer App to commission the IQ Battery(ies).
Once connected to the IQ Gateway, refer to the Enphase Installer
App help topics for more information.
B ) After the IQ Gateway has detected the IQ Battery(ies), the IQ Battery
LEDs operate as described in the following section.

OPERATION
a
LED overview
After being commissioned, the LED flashes yellow while each IQ Battery
boots up. If the LED rapidly flashes green for more than two minutes,
the battery is in trickle charge mode and will remain so until it reaches
a minimum state of charge (up to 30 minutes). After the IQ Battery is
booted up, the LED becomes blue or green depending on the charge
level. If the LED flashes yellow after one hour or changes to a flashing
red state, contact Enphase Customer Support at

* IQ Battery batteries have a one-hour orphan timer. If the IQ Gateway stops
communicating with them, after one hour the IQ Battery batteries return to an
“uncommissioned” state.

Troubleshooting
If the IQ Battery(ies) are not operating correctly, perform the following
steps. If the issue persists, contact Enphase Customer Support at
enphase.com/en-us/support/contact
A ) If the IQ Battery(ies) do not operate, check the temperature in the
room and increase cooling and/or ventilation as required. Check
that the front, top, and sides of the IQ Battery batteries have at
least 15cm (six inches) of unobstructed clearance.
B ) If the IQ Battery LED is off, turn off the breaker for the branch
circuit, wait for at least one minute, and turn it back on.
NOTE
: During a brownout or blackout, the IQ Battery powers down
automatically. This is normal. When power is restored, it automati-
cally starts up again.
C ) If you do not see IQ Battery information in Enphase Installer
Platform, check that the IQ Gateway and the Internet connection
are working. If the issue persists, contact Enphase Customer
Support at
enphase.com/en-us/support/contact
