PREPARATION
A ) Inspect the packaging and the IQ Battery(ies) for damage, such as cracks,
dents, or leaking electrolytes. Do not install or use the IQ 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 IQ Battery components:
•
The IQ Battery 10 includes three batteries and two inter-unit raceways,
an IQ Battery 10 triple-width cover, and a triple-width mounting bracket.
•
The IQ Battery 3 includes one battery and a single-width cover with a
mounting bracket.
✓ NOTE: Check the “Energize By” label on the shipping box to verify
that the IQ Battery(ies) will be installed by the date shown. If the date
has passed, contact your distributor to discuss the next steps.
* WARNING: Risk of injury. Take care when lifting. The IQ Battery unit
is heavy (44.2 kg/ 97.4 lb) and requires two persons to lift.
C ) Ensure you have the following required Enphase items for backup systems:
•
An Enphase IQ System Controller with microgrid interconnect device
(MID) functionality and an Enphase IQ Combiner.
•
The Enphase IQ Battery system requires an Internet connection
through the IQ Gateway 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 communications kit (COMMS-KIT-01) to be installed at
the IQ Gateway for communications with IQ Battery and IQ System
Controller. Includes USB cable for connection to IQ Gateway /
IQ Combiner and allows wireless communication with IQ Battery and
IQ System Controller.
•
IQ Battery lifting handles, two pieces (ENCHARGE-HNDL-R1).
D ) Make sure you also have the following required items:
•
Mounting location that is structurally suited to bearing the weight of
the IQ Battery(ies). the total weight for the IQ Battery 3, including the
IQ Battery base unit, cover, and wall-mount bracket, is 52 kg (114.6 lb).
Total weight for the IQ Battery 10, including the three IQ Battery base
units, cover, and wall-mount bracket, is 154.7 kg (341 lb). The wall
must contain blocked studs that can bear the battery weight or can be
made of masonry or other suitable structures.
•
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. Slots are 6.8 mm (0.27 inch). Check
with a structural engineer and local standards for requirements:
Single-wide bracket: Three 1/4” lag bolts or screws, 7.6 cm (3 inch)
long (depending on attachment wall).
Triple-wide bracket: Nine 1/4” lag bolts or screws, 7.6 cm (3 inch) long
(depending on attachment wall).
•
Washers for use between fastener heads and wall-mount brackets.
• Copper conductors: No. 14-8 AWG (11mm/7/16 inch strip length)
copper conductors rated at 75°C or 90°C (167ºF to 194ºF) for
terminals.
•
Conduit ttings: 3/4 inch (left side) and 1/2 inch (right side) hubs are
required for all installations, and NEMA Type 3R 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.
•
Overcurrent protection: The overcurrent protection in the IQ Battery is not
branch circuit overcurrent protection and cannot be relied upon for that
purpose. The branch circuit overcurrent protection is located in the IQ System
Controller or, when combining in a separate combiner. See the Enphase IQ
System Controller Quick Install Guide for more information.
•
Personal protective equipment (PPE) for handling lithium batteries as
required by local safety standards.
E ) Verify that the main service is 120/240 VAC and not 208/120 VAC.
IQ 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.
Self-consumption, no IQ System
Controller. The preferred conguration
is when adding battery storage and
PV for self-consumption in a grid-tied
application with no option for backup
during outages. PV and IQ Battery
will not operate when the grid is
unavailable.
Partial home backup with main load
panel as service entrance and
PV combiner connected to the
subpanel. This is the preferred
connection conguration for partial
home backup using a subpanel when
the PV circuit breaker size is more
than 80 A. The space available in the
IQ System Controller for combiner
(solar) connection is left vacant.
