enphase IQ Battery 3T User Manual

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 10T includes three batteries and two interconnect ca-
ble assemblies, an IQ Battery 10T triple-width cover, and a triple-width
mounting bracket.
•
The IQ Battery 3T includes one battery, and single-width cover with a
single-width 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 (40.5 kg/ 89.3 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
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.
D ) Make sure you also have the following required items:
•
Mounting location that is structurally suited to bear the weight of the
IQ Battery(ies). Total weight for the IQ Battery 3T, including the IQ
Battery base unit, cover and wall mount bracket, is 48.8 kg (107.6 lbs).
Total weight for the IQ Battery 10T, including the three IQ Battery base
units, cover, and wall mount bracket, is 143.6 kg (316.5 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. Slots are 9.2mm (0.36”). Check with
a structural engineer and local standards for requirements:
Single-width bracket for IQ Battery 3T: A minimum of three #20(5/16”)
lag bolts or screws, 7.6 cm (3 inches) long (depending on attachment
wall).
Triple-width bracket for IQ Battery 10T: A minimum of nine #20(5/16”)
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 ttings: 1/2 inch or 3/4 inch (left side) hubs are required for
all installations, and NEMA Type 3R conduit ttings (hubs) are needed
when installing outdoors.
•
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.
•
Protective gloves for protection against sharp edges.
E ) Verify that main service is 120/240 VAC, and not 208/120 VAC. IQ Batteries
cannot be installed where L1 to L2 measures 208 VAC.
F ) Note that the rated energy capacity of the battery is 3.36 kWh.
G ) 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 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 conguration 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.
