Powerwall Physical Requirements

Powerwall can be mounted on a floor or wall. When floor-mounted, it must also be anchored
to an adjacent wall. In both types of installation, the wall must be capable of supporting the full
weight of Powerwall and its mounting hardware. The wall must extend to all edges of the
system, allowing no access to the back of the unit once it is mounted.

Powerwall includes a mounting bracket (Fig. 1) that supports the unit in both floor- and wall­mount configurations, and includes shims to level the unit in floor-mount configurations. Do
not use other hardware to anchor Powerwall to the wall or floor.

Figure 1: Powerwall 2 Mounting Bracket Dimensions

Powerwall requires adequate clearance for installation, cabling, and airflow. Do not mount any
other objects within the clearance space (Fig. 2), except those explicitly required by the
installation (for example, conduit, a junction box, or an electrical disconnect, depending on
local installation codes). Do not install anything above Powerwall that limits access to the unit
or that might fall and damage the unit. Do not mount Powerwall horizontally or upside down.

NOTE: Powerwall has a pump and fan that enable Powerwall to maintain ideal battery
temperature. They produce a gentle hum during operation, comparable to a typical
refrigerator. The noise level depends on the ambient temperature and the power level of
operation. Consider these noise levels when choosing where to install Powerwall.

Powerwall Dimensions and Space Requirements

Figure 2: Powerwall 2 Dimensions and Space Requirements

Powerwall Temperature Requirements

Powerwall is capable of charging and discharging within the full ambient temperature range
listed in the Specifications section. At the high and low ends of the temperature range,
Powerwall may limit charge or discharge power based on battery cell temperature to improve
battery lifespan.

Installation in full sun raises the temperature inside the enclosure above ambient temperature.
This temperature rise is not a safety risk, but may impact battery performance. To optimize
performance, avoid installing Powerwall in locations that are exposed to the sun for extended
periods.

Do not install Powerwall in locations with sustained high or low temperatures. The average
ambient temperature over the system's life should be between 0°C and 30°C (32°F and 86°F).

with solar systems and the electrical grid. The Backup Gateway communicates with the
system by means of wireless and wired connections. Wiring and conduit (where required)
must be provided by the installer. Where conduit is required, the installation must comply with
local codes and UL514B requirements.

AC disconnect and interconnection requirements between the Powerwall system and the
electrical panel are subject to local codes. Ensure that the installation meets local disconnect
and interconnection requirements.

All U.S. and Canada electrical installations must be done in accordance with local codes and
the National Electric Code (NEC) ANSI/NFPA 70 or the Canadian Electrical Code CSA C22.1.

When Powerwall is installed in a dwelling unit, a smoke alarm should be installed in the same
room as the Powerwall, in accordance with local building and fire codes.

All installations must conform to the laws, regulations, codes, and standards applicable in the
jurisdiction of installation.

Backup Gateway Installation Requirements

The Backup Gateway should be wall-mounted and can be configured for cable entry at the
top, bottom, or sides of the enclosure. It requires adequate clearance for installation and
cabling or conduit. Wiring and conduit (where required) must be provided by the installer.
Where conduit is required, the installation must comply with local codes and UL514B
requirements.

10 Powerwall Installation Manual

Step 1. Plan the Installation Site

Maximum

Cable Length

The installation location for Powerwall must accommodate placement of the Backup Gateway
and meet all conditions described above in “Site Requirements.” In addition, consider the
following points when choosing where to install Powerwall.

Wall mounting: Choose a wall capable of supporting the full weight of Powerwall, with one of
the following characteristics: wood studs at regular intervals, plywood sheeting of sufficient
thickness, solid concrete or masonry, or metal studs of sufficient gauge.

Floor mounting: Choose a level surface adjacent to a wall space that meets all the
requirements for wall mounting described above. Make sure the area is isolated from hazards
that may damage the unit, such as vehicle traffic or flooding.

Cable entry: Determine whether cables will be routed into Powerwall from the side or from the
back of the unit. With side cable entry, a conduit fitting or cable gland must be used to seal
the entry into the wiring compartment. With back cable entry, a wire cover should be used to
seal the entry into the wiring compartment.

NOTE: If you mount Powerwall on a wall with studs spaced 24 in (610 mm) apart, cable entry
from the back of Powerwall may be blocked.

Backup Gateway configuration: Determine whether cable entry into the Backup Gateway will
be from the top, bottom, or side. When cable entry is from the bottom half of the enclosure,
the back panel of the unit must be removed and rotated 180 degrees.

NOTE: For cable entry at the top of the Backup Gateway enclosure, an HS-style hub should be
used in order to maintain enclosure ingress protection.

Electrical service connection: The Backup Gateway is service-entrance rated, and can be
located between the service entry and the main electrical panel. If overcurrent protection is
required, a circuit breaker can be added to the Backup Gateway at the service entry. The
Backup Gateway can accommodate two different circuit breaker sizes: 100/125A, and
150/200A.

Cable gauge and length: Powerwall requires cable connections to the Backup Gateway,
electrical service panel(s), and an Internet router. Position Powerwall, the Backup Gateway,
and other electrical components to minimize cable lengths, based on local code requirements.

Cable Type Connection Cable Gauge

Power Powerwall to electrical panel 5-8 mm2 (10-8 AWG) 45 m (150 ft)

Power Backup Gateway to electrical panel 16–120 mm2 (6 AWG-250 kcmil) [Local Code]

Step 5. Mount Powerwall on the Bracket

1. Move the lift equipment close to the wall and remove the tie-down strap securing the
Powerwall to the lift equipment.

2. Adjust the height of the Powerwall so that its mounting cleats are just above the flanges on
the bracket. (If you marked the bracket and cleat locations, use those marks to gauge the
height.)

3. Begin to lower the Powerwall so that the top cleat engages the top flange on the bracket.
Ensure that the bottom cleat aligns with the bottom flange of the bracket.

4. With both cleats engaged, lower the Powerwall onto the bracket. When the cleats are
seated in the bracket, the locking mechanism at the center of the top flange should click into
place.

NOTE: To remove Powerwall from the mounting bracket, place a thin piece of sheet metal
between the Powerwall unit and the bracket to compress the locking mechanism, and lift the
Powerwall straight up.

If the Backup Gateway is to be located between the electrical service entry and the main
electrical panel, a circuit breaker must be added to the service inlet of the Backup Gateway. If
no circuit breaker is required, skip to Step 8, “Mount the Backup Gateway.”

WARNING: If a circuit breaker is not added to the Backup Gateway, ensure that

appropriate overcurrent protection is provided for the installation.

CAUTION: To reduce the risk of fire, connect only to a circuit provided with 200 A
maximum branch-circuit overcurrent protection, in accordance with the National Electrical
Code, ANSI/NFPA 70.

The following circuit breaker models are supported:

Circuit Breaker Model Amperage Rating UL Type

1. Determine the level of overcurrent protection required, based on local code requirements.

2. Remove the service inlet terminal lugs from the Backup Gateway. (It may be necessary to
remove the meter current transformers to access the nuts holding the lugs in place.)

Figure 27: Removing the Inlet Service Terminal Lugs

3. Install the corresponding size circuit breaker at the service inlet terminals in the Backup
Gateway.

27

4. Remove and rotate the dead front panel insert (and its insulation) so that the correct
punch-out will match the breaker location when the panel is replaced. For smaller (100 A and
125 A) circuit breakers, remove the small punch-out; for larger (150 A and 200 A) circuit
breakers, remove the large punch-out.

NOTE: The location of the breaker also depends on the orientation of the back panel
assembly.

Figure 28: Dead Front Panel Insert Orientations for Circuit Breakers

Step 8. Mount the Backup Gateway

1. Determine the mounting location. The Backup Gateway enclosure has 3 mounting holes
(shown below in red). If needed, two additional mounting points (shown below in grey) are
also available. To use these additional mounting points, the back panel must be removed and
the points drilled out.
