1. Registering Powerwall
Tesla Powerwall comes with a warranty whose term depends on the connection of Powerwall
to the Internet.
To secure the full 10-year warranty for Powerwall, it must be reliably connected to the Internet
to allow remote firmware upgrades from Tesla. If an Internet connection is not established or is
interrupted for an extended period, and Tesla is unable to contact the owner, the warranty
may be limited to 4 years. To ensure that the owner can receive the full 10-year warranty,
register the Powerwall by visiting www.tesla.com/support/powerwall.
For more information, refer to the Powerwall Warranty for your region at www.tesla.com.

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 (32°F and 86°F).
