QUICK INSTALL GUIDE (Models ENCHARGE-3-1P-NA and ENCHARGE-10-1P-NA)
Install the Enphase IQ Battery
To install the Enphase IQ Battery 3 or IQ Battery 10 and the Enphase wall-mount bracket, read and follow all warnings and instructions in this guide. Safety
warnings are listed on the back of this guide. These instructions are not meant to be a complete explanation of how to design and install an energy storage
system. All installations must comply with national and local electrical codes and standards. Only qualied electricians shall install, troubleshoot, or replace
the IQ Battery 3 or IQ Battery 10.
The IQ Battery includes the Enphase IQ Battery(ies) with integrated Enphase IQ Microinverters. The Enphase IQ Gateway communication gateway mea-
sures PV production and home energy consumption. The IQ Battery senses when it is optimal to charge or discharge the battery so that energy is stored
when it is abundant and used when scarce. IQ Batteries are capable of providing backup power when an Enphase IQ System Controller is installed at the
site.
Five unique installation
scenarios are shown:
Whole home backup with IQ System
Controller as service entrance and
PV combiner connected to IQ System
Controller. This is the preferred
conguration for back up of the entire
main load panel. This conguration
supports up to an 80A breaker for
the PV circuit and an 80A breaker for
battery storage.
Whole home backup with IQ System
Controller as service entrance and
PV combiner connected to main
load panel. This is the preferred
conguration when you back up the
entire main load panel, and the size
of the PV combiner circuit is more
than 80A. In this conguration, the PV
combiner circuit connection space
in IQ System Controller is left vacant.
When existing PV combiner circuits
are connected to the main load
panel, and you want to add battery
storage to the system, you can keep
the PV combiner connected to the
main load panel and connect only the
battery storage system to IQ System
Controller.
Partial home backup with main load
panel as service entrance and PV
combiner connected to IQ System
Controller. When PV circuits breaker
size is less than 80A, this is the
preferred conguration for partial
home backup with subpanel.

INSTALLATION
Plan a location for the IQ Batteries
The IQ Battery housing is NEMA type 3R and can be installed indoors or out-
doors. The terminal blocks accepts copper conductors of No. 14 - 8 AWG.
A ) Following local standards, choose a well-ventilated location where
the ambient temperature and humidity are within -15° C to 55° C
(5° F to 131° F) and 5% to 100% RH, non-condensing, preferably out
of direct sunlight. The optimum ambient temperature range for
installation location is 0º C to 30º C (32º F to 86º F).
B ) Ensure that the mounting location can sustain the total weight
of the IQ Batteries and mounting bracket. Total weight for the IQ
Battery 3, including the IQ Battery base unit, cover and wall mount
bracket, is 52 kg (114.6 lbs). Total weight for the IQ Battery 10,
including the three IQ Battery base units, cover, and wall mount
bracket, is 154.7 kg (341 lbs).
*WARNING: The installer should install blocking between studs
to ensure that no single stud carries the entire weight load of the
IQ Batteries.
C ) Plan the mounting location to be at least 15cm (six inches) off the
ground and 15cm (six inches) from the ceiling. Keep the IQ Battery
away from falling or moving objects, including motor vehicles.
*WARNING: If mounted in the path of a motor vehicle, we
recommend a mounting height that is 91 cm (36-inch) minimum
above the oor.
D ) Ensure that there are no pipes or electrical wires where you plan to drill.
E ) Plan to maintain at least three feet of clearance in front of each
IQ Battery. Allow at least 15cm (six inches) clearance on top and
bottom of the IQ Battery so that the vents on the top and bottom of
the units are not blocked for air circulation.
F ) Consider the dimensions of the IQ Batteries, easy access, height,
and length of cable when selecting the location.
G ) Select a location where you can interconnect to the Enphase IQ
System Controller.
H ) Follow all local standards.
J ) Review your external conduit plan to determine to which side of the
eld wiring compartment you will connect conduit.
K ) Up to two IQ Battery 10 (or six IQ Battery 3) units can be daisy
chained on a single branch circuit. For installations with more than
this number of units, there must be a separate load center, subpanel,
or circuit combiner with over current protection to combine the
daisy chained circuits, and you must run only one circuit for all
the IQ Battery units to the IQ System Controller (or to Enphase IQ
Combiner for grid-tied-only installations). You must select proper
conductors and circuit breakers for these circuits according to local
codes, standards, and other applicable requirements. IQ System
Controller supports up to a maximum of 80 A breaker for IQ Battery
connection circuit.
The subpanel could be a small, two circuit box with circuit breakers.
The circuit breakers in the box would have to be suitable for
back-feeding, per NEC 408.36(D).
Select the right size subpanel and breakers based on the number of
IQ Battery units being installed. Up to four IQ Battery 10s or twelve IQ
Battery 3s can be safely connected to 80A load center.
To do this, you must purchase an off-the-shelf subpanel and install
as shown in the following image:
* WARNING! Parallel power production sources only. Do not
connect load circuits.
1Install the AC disconnect
Following all local codes and standards:
A ) Install an AC disconnect that can break the maximum rated current
of the branch circuit under load. The AC disconnect must be readily
accessible and located within line-of-sight of IQ Battery, per NEC
2017 706.7(A).
B ) Each IQ Battery unit is suitable for use with up to No. 8 AWG wires
on a maximum 40 A branch circuit. If more than 32 A of IQ Battery
batteries (corresponding to a 40 A branch circuit) are installed, a
separate subpanel must be installed between the IQ Battery units
and IQ System Controller to combine the IQ System Controller
circuits together. All circuit breakers in the subpanel must be
suitable for back-feeding, per NEC 408.36(D).
C ) Verify that AC voltage at the site is within range: single-phase L1 to L2
voltage must measure between 211 and 264 VAC, while L-N should
measure between 106 and 132 VAC.
2
Prepare to install the wall-mount bracket
A ) Make sure that the planned position for the wall-mount bracket
meets clearance requirements as shown. The image depicts a
single bracket, but clearances and requirements are the same for
the triple-width bracket.
B) Ensure that the mounting location can sustan the weight of the
IQ Batteries and mounting bracket. Total weight for the IQ Battery
3 including the mounting brackets and cover is 52 kg (114.6 lbs),
while the total weight for IQ Battery 10 including the mounting
bracket and cover add up to 154.7 kg (341 lbs).
C ) Starting at installation position closest to the power source, mark a
level line on the wall as a guide.
* WARNING! Multiple risks. Make sure not to drill or attach into
electric wiring or pipes that are in the wall!

and insert the raceway through
the right-hand unit’s left-side
conduit opening from within
the eld wiring compartment,
with the arm of the raceway
pointing up.
• Push the raceway through the right-hand unit’s left-side conduit
opening and into the left-side unit’s right-side conduit, opening until the
two snap features on the raceway engage the left-side unit’s enclosure.
• Once fully inserted, rotate the “arm” toward you until it stops.
• The left-side conduit opening of each battery unit has a at surface,
without additional features. The larger seal (green) on the raceway
mates with this opening. The right-side conduit opening has a
groove around the hole to t the O-ring (red) of the raceway. Make
sure that the O-ring is captured in the groove between the IQ Battery
enclosure and the raceway ange adjacent to the O-ring.
E ) Using the conductors and suitable conduits, connect the AC dis-
connect and the rst adjacent IQ Battery. Use the conduit openings
provided to connect the conduit and pass the wires through them.
Note that if an Enphase IQ System Controller is in line-of-sight, the
breaker can service as a disconnect.
* WARNING! Risk of equipment damage. Do not modify or rewire
the pre-installed wiring or bonding connections in the eld wiring
compartment.
* WARNING! Risk of equipment damage. Always connect to two
Lines (active) and one ground.
F ) Connect each wire in the eld wiring compartment to its correspond-
ing conductor (Lines and Ground). Each terminal accepts two 14-8
AWG conductors (11mm/7/16 inch strip length). Tighten to 14 lb-in.
G ) If installing an IQ Battery 10, route the wires from the rst IQ Battery
to the adjacent IQ Battery through the inter-unit raceway. There are
two positions for each line and for ground in the terminal block to
allow for daisy-chaining.
* WARNING! Risk of equipment damage. Do not daisy chain more
than six total IQ Battery 3 or two IQ Battery 10 on a single branch
circuit.
H ) After all wires in the eld wiring compartment are connected and
secured, check that there are no exposed conductors.
I ) If connecting additional IQ Batteries, use another conduit and another
set of wires to connect between eld wiring compartments.
J ) Gently arrange all the wires and connectors inside the eld wiring
compartment.
6K ) Plug any unused conduit openings before proceeding.
L ) Replace the eld wiring compartment cover. Use a cross-head
screw driver to tighten the cover screws to 2.3Nn (20.3 Ib-in).

*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 eld 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 rmware. 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 rst 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)

bTroubleshooting
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.
