3. Site Requirements
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 wall-
mount 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 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.

Powerwall Installation Requirements
Powerwall comes with a separate Backup Gateway and power meter to enable integration
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.
AC disconnect and interconnection requirements between the Powerwall system and the main
switchboard are subject to local codes. Ensure that the installation meets local disconnect and
interconnection requirements.
When Powerwall is installed in a dwelling unit, fire detection and protection equipment should
be installed 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 must 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.
Mount the Backup Gateway vertically, in the orientation shown below (Fig. 3). Do not mount
the Backup Gateway enclosure horizontally or upside down.

Step 1. Plan the Installation Site
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 Powerwall is mounted 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. (Optional: when cable entry is from the bottom half of the
enclosure, the back panel of the unit may be rotated 180 degrees to simplify cable runs.)
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 main switch and the switchboard.
