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, be sure to complete the commissioning process so that
registration information is sent to Tesla.
For more information, refer to the Powerwall Warranty for your region at www.tesla.com.
Site Requirements and Pre-Installation Guidance
Powerwall and Backup Gateway 2 Installation Requirements
Powerwall comes with a separate Backup Gateway to enable integration with the electrical grid and
generation like solar systems (refer to Compatibility Matrix for information on what can be connected with
Powerwall). 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 distribution
board are subject to local codes. Ensure that the installation meets local disconnect and interconnection
requirements.
) side of the Backup
.
WARNING: When Powerwall is installed in a dwelling unit, fire detection and protection equipment should
be installed in accordance with local building and fire codes.
WARNING: Do not connect the Backup Gateway in any way that bypasses or short-circuits its relay.
WARNING: Do not connect the Backup Gateway to the source side only or to the load side only. The
Backup Gateway must have both source and load connections, and must be wired in compliance with local
codes.
CAUTION: The Backup Gateway may not be recessed into a wall or cavity.
CAUTION: The Manual Override switch inside of the product must not be used to simulate a grid outage
or take home off-grid. A main isolation switch should be installed upstream of the Backup Gateway for
testing the system and for service purposes.
NOTE: All installations must conform to the laws, regulations, codes, and standards applicable in the
jurisdiction of installation.

Powerwall Physical Requirements
Powerwall can be mounted on a floor or wall, and includes a mounting bracket to support either
configuration. Mounting Powerwall must follow the guidance outlined in this document. Mounting
requirements based on wall type are provided in Appendix A: Powerwall Mounting Details
Powerwall requires adequate clearance for installation, cabling, and airflow. 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 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 Identification
Newer Powerwalls have slightly different dimensions for mounting-bracket height. Powerwalls may be easily
identified by part number and by comparing the back of the Powerwall (see Figure 2).
Figure 2: Powerwall 2 Identification by Mounting Bracket Height
Powerwall Optimum Temperature Range
Powerwall is rated to operate in temperatures from 4°F to 122°F (-20°C to 50°C). However, for best
performance Tesla recommends installing Powerwall in locations with ambient temperature between 32°F
and 86°F (0°C to 30°C) year round. When outside this recommended temperature range, charge/discharge
power may be reduced and Powerwall will utilize its thermal control system more frequently to maintain
battery cell temperature which will reduce the energy efficiency of the system. Systems operating off-grid
for long periods (>4 hours) in cold weather systems may need to curtail PV, and reduce energy used for pre-
conditioning.
•For cold climates, Tesla recommends installing Powerwall indoors when possible (particularly when
long outages are expected).
•For hot climates Tesla recommends keeping Powerwall out of direct sunlight. 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.
Additionally, if stored in a cold environment (e.g. below 0°C) before installation, it may take several hours for
Powerwall to raise its internal temperature using pre-conditioning. Tesla recommends storing Powerwalls in a
warm location prior to installation to help efficiently commission and test the system.
