PREPARATION
A ) Inspect the packaging and the IQ Battery(ies) for damage, such as cracks,
dents, or leaking electrolyte.
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 single-width cover with
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 for next steps.
*
WARNING
: Risk of injury. Take care when lifting. The IQ Battery unit
is heavy (44.2 kg/ 97.4 lbs) 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
•
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). 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).The
wall must contain blocked studs that can bear the battery weight or
can be of masonry or other suitable structure.
•
Tools: conduit (with fittings and fitting tools), drill, 5/32 inch pilot bit
(or metric equivalent), screwdriver, socket wrench, torque wrench,
level, wire stripper, and stud finder if installing on studs.
•
Fasteners for wall mount bracket. Slots are 6.8mm (0.27”). Check
with a structural engineer and local standards for requirements:
Single-wide bracket: Three 1/4” lag bolts or screws, 7.6 cm (3
inches) long (depending on attachment wall).
Triple-wide bracket: Nine 1/4” lag bolts or screws, 7.6 cm (3 inches)
long (depending on attachment wall).
•
Washers for use between fastener heads and wall-mount bracket.
•
Copper conductors: No. 14 - 8 AWG
(11mm/7/16 inch strip length)
copper conductors (rated at 75° C or 90° C) for terminals.
•
Conduit fittings: 3/4 inch (left side) and 1/2 inch (right side) hubs
are required for all installations, and NEMA Type 3R conduit fittings
(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 IQ Battery is not
branch circuit overcurrent protection and cannot be relied upon for that
purpose. The branch circuit overcurrent protection is located in 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 main service is 120/240 VAC, and not 208/120 VAC. IQ Battery
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 configuration
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 subpanel.
This is the preferred connection
configuration for partial home backup
using a subpanel when the PV circuit
breaker size is more than 80A. The
space available in IQ System Controller
for combiner (solar) connection is left
vacant.
