Mount the Encharge Battery(ies) on the wall
*
WARNING
: Risk of injury. Take care when lifting.
Each Encharge battery base unit is heavy (40.5 kg/ 89.3 lbs) and
requires two persons to lift.
*
WARNING!
Risk of injury and equipment damage. Avoid dropping
the Encharge Battery(ies). Doing so may create a hazard, cause seri-
ous injury, and/or damage the equipment.
*
WARNING!
Risk of injury and equipment damage. Protect the
Encharge Battery(ies) from impact damage and improper use.
*
WARNING!
Risk of injury and equipment damage. Do not hold the
microinverters to lift the unit during installation.
A ) Two person together must lift a single Encharge battery base unit
from the packaging and place it in upright position (as shown in the
following image) on a flat surface.
B ) Locate the Encharge lifting points:
C ) The first person lifting must use points
a
and
d
(as shown) to lift the
battery.
D ) The second person lifting must use points
b
and
c
(as shown) to lift
the battery.
E ) Together, lift the Encharge battery and bring it to the already
mounted bracket.
F ) Hold the Encharge battery straight so that the four bolts on the back
of the Encharge battery pass through the four key hole slots on the
corner of the mounting bracket.
*
WARNING!
Risk of injury and equipment damage. Do not release
the Encharge battery unit until you ensure that the Encharge battery
unit is fully seated in the wall-mount bracket shelf.
G ) Once all four battery bolts fully pass through the mounting bracket
key hole slots, lower the battery down until fully seated within the
wall-mount bracket and set into the bottoms of the key holes.
H ) Attach the battery to the mounting bracket aligning the screw hole
at the bottom of the battery with the screw hole at the bottom of the
bracket. Tighten the bottom screw to 8Nm (70.8 lb-in).
I ) To record the installation of each Encharge battery base unit, scan
the serial number label using Enphase Installer Toolkit™ and your
mobile device.

DANGER!
Risk of electric shock. The DC switch must be in the
Locked position before performing this step.
A ) Drill the left wall of field wiring compartment to accommodate the conduit.
B ) Connect field wiring to the top three terminal blocks.
C ) Size the conductors (Lines and Ground) to account for voltage rise and
to conform to the tables below. Design for a voltage rise total of less
than 2%. Encharge can use any circuit breaker size between 10 A and
40 A. Breaker rating and wire size are installation dependent.

In all cases in the table, it is possible to always use larger conductors
and a breaker sized for that conductor or smaller. For Example in row 3,
with 3*E3T or 1*E10T, it is possible to use:
a) 12 AWG wire with 20 A breaker, or
b) 10 AWG wire with 20 A or 30 A breaker, or
c) 8 AWG wire with 30, 35, or 40 A breaker

DANGER!
Risk of electric shock. Check that the dedicated circuit
breaker protecting the branch where the Encharge Battery(ies) will be
connected is turned off before wiring.
*
WARNING!
Risk of equipment damage. The DC switch must be
OFF before installing, otherwise Encharge will try to form a grid.

DANGER!
Risk of electric shock. The DC switch must be in the
locked position before performing this step.
A )
If installing an Encharge 10T
, install the interconnect cable assembly.
• Face the front of the batteries, and insert the interconnect cable
assembly through the front cable slot from within the field wiring
compartment, with the arm of the interconnect cable pointing up,
making a “U” shape.
B ) Using the conductors and suitable conduits, connect the AC disconnect
and the first adjacent Encharge Battery. Use the conduit openings
provided to connect the conduit and pass the wires through them. Note
that if an Enphase Enpower is in line-of-sight, the breaker can service
as a disconnect.
*
WARNING!
Risk of equipment damage. Do not modify or rewire the
pre-installed wiring or bonding connections in the field wiring compart
-
ment.
*
WARNING!
Risk of equipment damage. Always connect to two
Lines (active) and one ground.
