Install the Enphase
Encharge Storage System
To install the Enphase
Encharge 3T
™ storage system or
Encharge 10T
™ storage system 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 qualified electricians shall
install, troubleshoot, or replace the Encharge 3T or Encharge 10T.
The Encharge
™
storage system includes the Enphase Encharge Battery(ies) with integrated Enphase IQ
™
Microinverters. The Enphase Envoy™ communica
-
tion gateway measures PV production and home energy consumption. The Encharge 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.
Unique installation scenario is shown below:

Self consumption, grid tied.
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 Encharge will not operate when the
grid is unavailable.
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 10T
includes three batteries and two interconnect cable
assemblies, an Encharge 10T triple-width cover, and a triple-width
mounting bracket.
•
The
Encharge 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 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 (40.5 kg) and requires two persons to lift.
C ) Ensure you have the following
required Enphase items
:
•
The Enphase Encharge system requires an Internet connection
through the Envoy. Failure to maintain an Internet connection may
have an impact on the warranty. See
terms.
•
Wireless communications kit (COMMS-KIT-EU-01) to be installed at
the Envoy for communications with Encharge. Includes USB cable for
connection to Envoy along with communication extender and allows
wireless communication with Encharge
D ) Make sure you also have the following
required items
:
•
Mounting location that is structurally suited to bear the weight of the
Encharge Battery(ies). Total weight for the Encharge 3T, including the
Encharge base unit, cover and wall mount bracket, is 48.8 kgs. Total
weight for the Encharge 10T, including the three Encharge base units,
cover, and wall mount bracket, is 143.6 kgs.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, 4 mm pilot bit,
screwdriver, socket wrench, torque wrench, level, wire stripper, and
stud finder if installing on studs.
•
Fasteners for wall mount bracket. Slots are 9.2 mm. Check with a
structural engineer and local standards for requirements:
Single-width bracket for Encharge 3T: A minimum of three #8 mm lag
bolts or screws, 7.6 cm long (depending on attachment wall).
Triple-width bracket for Encharge 10T: A minimum of nine #8 mm lag
bolts or screws, 7.6 cm long (depending on attachment wall).
•
Washers for use between fastener heads and wall-mount bracket.
•
Copper conductors: 2.5 - 10 mm
2
(11mm strip length) copper
conductors (rated at 75° C or 90° C) for terminals.
•
Conduit fittings: 12 mm or 20 mm (left side) terminators are required
for all installations, and IP54 conduit fittings are needed when
installing outdoors.
•
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 SHALL be located separately.
•
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 230 V L-N. Encharge batteries cannot be installed
between L1 and L2.
F ) Note that the rated energy capacity of the battery is 3.5 kWh.
G ) Install the PV system as directed by the Enphase installation manuals.
