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 inter-unit 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 “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 next steps.
*
WARNING
: Risk of injury. Take care when lifting. The Encharge
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 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
•
Wireless communications kit (COMMS-KIT-01) to be installed at the IQ
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.
•
Encharge 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 Encharge Battery(ies). Total weight for the Encharge 3, including
the Encharge base unit, cover and wall mount bracket, is 52 kg (114.6
lbs). Total weight for the Encharge 10, including the three Encharge
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. Check with a structural engineer
and local standards for requirements.:
Three #10 lag bolts or screws, 7.6 cm (3 inches) long (depending
on attachment wall), for each single-wide wall-mount bracket.
Nine #10 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 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 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.
