QUICK INSTALL GUIDE (Models ENCHARGE-3-1P-NA and ENCHARGE-10-1P-NA)
Install the Enphase Encharge Storage System
To install the Enphase Encharge 3™ or Encharge 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 Encharge 3 or Encharge 10.
The Enphase Storage System includes the Enphase Encharge Battery(ies) with integrated Enphase Microinverters™. The Enphase IQ Envoy™ gateway
measures PV production and home energy consumption. The Enphase Storage System senses when it is optimal to charge or discharge the battery so that
energy is stored when it is abundant and used when scarce. Encharge storage systems are capable of providing backup power when Enphase Enpower™ is
installed at the site.
Five unique installation scenari-
os are shown:
Whole home backup with Enpower
as service entrance and PV combiner
connected to Enpower. 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 Enpower
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 Enpower 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 Enpower.
Partial home backup with main load
panel as service entrance and PV
combiner connected to Enpower.
When PV circuits breaker size is
less than 80A, this is the preferred
conguration for partial home backup
with sub-panel.

PREPARATION
A ) Inspect the packaging and the Encharge Battery(ies) for damage, such
as cracks, dents, or leaking electrolyte. Do not install or use the Encharge
Battery(ies) if it has been damaged in any way. If damaged, contact your
distributor for replacement.
B ) Ensure that your kit includes the following Encharge components:
• The Encharge 10 includes three batteries and two interunit raceways,
an Encharge 10 triple-width cover, and a triple-width mounting bracket.
• The Encharge 3 includes one battery, and single-width cover with
mounting bracket.
NOTE: Check the “Must Energize By” label on the shipping box to verify
that the Encharge Battery(ies) will be installed by the date shown. If the
date has passed, contact your distributor for replacement.
* WARNING: Risk of injury. Take care when lifting. The Encharge
Battery unit is heavy (47 kg/ 104 lbs) and requires two persons to lift.
C ) Ensure you have the following required Enphase items for backup systems:
• An Enphase Enpower smart switch with microgrid interconnect device
(MID) functionality and an Enphase IQ Combiner.
• The Enphase Encharge system requires an Internet connection
through the IQ Envoy in the IQ Combiner. Failure to maintain an
Internet connection may have an impact on the warranty. See
enphase.com/warranty for full terms.
• Wireless USB Adapter (COMMS-KIT-01) to be installed at Envoy for
communications with Encharge and Enpower. Includes USB cable for
connection to IQ Envoy / IQ Combiner and allows redundant wireless
communication with Encharge and Enpower.
D ) Make sure you also have the following required items:
• Mounting location that is structurally suited to bearing the weight of
the Encharge Battery(ies). Total weight for the Encharge 3 is 53 kg
(117 lbs), while the three battery units in the Encharge 10 add up to
157 kg (346 lbs). The wall must contain blocked studs that can bear
the battery weight or can be of masonry or other suitable structure.
• Tools: conduit (with ttings and tting tools), drill, 5/32 inch pilot bit
(or metric equivalent), screwdriver, socket wrench, torque wrench,
level, wire stripper, and stud nder if installing on studs.
• Fasteners for wall mount bracket. Check with a structural engineer and
local standards for requirements.:
Three #8 lag bolts or screws, 7.6 cm (3 inches) long (depending on
attachment wall), for each single-wide wall-mount bracket.
Nine #8 lag bolts or screws, 7.6 cm (3 inches) long (depending on
attachment wall), for each triple-wide wall-mount bracket.
• Washers for use between fastener heads and wall-mount bracket.
• Copper conductors: No. 12 - 8 AWG (11mm/7/16 inch strip length)
copper conductors (rated at 75° C or 90° C) for terminals.
• Conduit ttings: 3/4 inch (left side) and 1/2 inch (right side) hubs are
required for all installations, and NEMA Type 3 conduit ttings (hubs)
are needed when installing out of doors (one for each used conduit
opening). Also needed are conduit plugs to close unused conduit
openings and conduit grounding nuts.
• Over current protection: The overcurrent protection in Encharge is not branch
circuit overcurrent protection and cannot be relied upon for that purpose.
The branch circuit overcurrent protection is located in Enpower or, when
combining , in a separate combiner. See the Enphase Enpower Quick Install
Guide for more information.
• Personal protective equipment (PPE) for handling lithium batteries as
required by local safety standards.
E ) Verify that main service is 120/240 VAC, and not 208/120 VAC. Encharge
batteries cannot be installed where L1 to L2 measures 208 VAC.
F ) Install the PV system and the IQ Combiner as directed by the Enphase
installation manuals.
G ) To record the installation of the Encharge Battery(ies), scan or remove the
serial number label for each battery and add it to the respective location
on a paper installation map. You will scan this map later using Enphase
Installer Toolkit™ and your mobile device. You can nd an example
installation map at the back of any Enphase Microinverter manual.
Self consumption, no Enpower smart
switch. The preferred conguration
when adding battery storage and PV
for self-consumption in a grid-tied
application with no option for backup
during outages. PV and Encharge will
not operate when the grid is unavailable.
Partial home backup with main
load panel as service entrance
and PV combiner connected to
sub-panel. This is the preferred
connection conguration for partial
home backup using a subpanel
when the PV circuit breaker size is
more than 80A. The space available
in Enpower for combiner (solar)
connection is left vacant.

INSTALLATION
Plan a location for the Encharge batteries
The Encharge housing is NEMA type 3R and can be installed indoors or out-
doors. The terminal blocks accepts copper conductors of No. 12 - 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.
B ) Ensure that the mounting location can sustain the weight of the
Encharge batteries and mounting bracket. Total weight for the
Encharge 3 is 53 kg (117 lbs), while the three battery units in the
Encharge 10 add up to 157 kg (346 lbs).
*WARNING: The installer should install blocking between studs
to ensure that no single stud carries the entire weight load of the
Encharge batteries.
C ) Plan the mounting location to be at least 30cm (one foot) off the
ground and 30cm (one foot) from the ceiling. Keep the Encharge
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 En-
charge. Allow enough clearance on top and sides of the Encharge
so that the vents on the cover are not blocked.
F ) Consider the dimensions of the Encharge batteries, easy access,
height, and length of cable when selecting the location.
G ) Select a location where you can interconnect to the Enphase
Enpower MID.
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 Encharge 10 (or six Encharge 3) units can be daisy
chained on one 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 Encharge
units to the Enpower (or to Enphase AC Combiner for grid-tied-only
installations). You must select proper conductors and AC discon-
nects for these circuits according to local codes, standards, and
other applicable requirements. Enpower supports up to a maximum
of 80 A breaker for Encharge connection circuit.
The subpanel could be a small, two circuit box with circuit breakers
(the drawing only shows switches). 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
Encharge units being installed. If there are only three Encharge 10s,
for example, then you can use a box with current rating less than
80A.
To do this, you must purchase an off-the-shelf subpanel and install
as shown in the following image:
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
installed in line-of-sight of Encharge, per NEC 706.7(A).
B ) Each Encharge 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 Encharge
batteries (corresponding to a 40 A branch circuit) are installed, a
separate subpanel must be installed between the Encharge units
and Enpower to combine the Enpower 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 sustain the weight of the
Encharge batteries and mounting bracket. Total weight for the
Encharge 3 is 53 kg (117 lbs), while the three battery units in the
Encharge 10 add up to 157 kg (346 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!

+ DANGER! Risk of electric shock. Check that the dedicated circuit
breaker protecting the branch where the Encharge Battery(ies) will
be connected is turned off before wiring.
* WARNING! Risk of equipment damage. The DC switch must be
OFF before installing, otherwise Encharge will try to form a grid.
C ) Use a Phillips screw driver to loosen the screws securing the eld wiring
compartment cover and remove the cover. Keep the cover handy as you
will need it later.
D ) If installing an Encharge 10, install the interunit raceways. The left-
side and right-side conduit openings are different diameters, so you
must install the raceway in the proper direction.
• Face the fronts of the batteries, 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 Encharge
enclosure and the raceway ange adjacent to the O-ring.
6 Install conduit and eld wiring, continued
E ) Using the conductors and suitable conduits, connect the AC discon-
nect and the rst adjacent Encharge Battery. Use the conduit openings
provided to connect the conduit and pass the wires through them.
Note that if an Enphase Enpower 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 12-8
AWG conductors (11mm/7/16 inch strip length). Tighten to 14 in lb.
G ) If installing an Encharge 10, route the wires from the rst Encharge
Battery to the adjacent Encharge Battery through the interunit
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 Encharge 3 or two Encharge 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 Encharge 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.
K ) Plug any unused conduit openings before proceeding.
