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. te s la .c om .
Site Requirements and Pre-Installation Guidance
Pow er wall and Backup Gate way 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 and UL514B requirements.
AC isolation and interconnection requirements between the Powerwall system and the electrical panel are
subject to local codes. Ensure that the installation meets local isolation 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.
A WARNING: All Powerwalls in the system must be installed on the ' Backup' side of the Backup Gateway's
relay.
A 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.
A WARNING: Do not connect the Backup Gateway in any way that bypasses or short-circuits its relay.
A 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 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.
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 and UL514B requirements.

Powerwall Optimum Temperature Range
Po werwa ll is rated to operate in temperature s from -4 °F to 122°F ( -20° C to 50°C). H owever, for best
performance Tesla recommends installing Po we r wa ll in locations w ith ambient temperature bet wee n 32°F to
86°F (0°C to 30°C ) ye ar round. W hen outside this re co mmended temperature range , charge po we r ma y be
reduced and Po werwa ll will utilize its thermal co ntrol system more frequentl y to maintain batter y cell
temperature , w hich will reduce the energy efficiency of the system. Systems that experience long outages
(> 4 hours ) in co ld wea ther systems ma y need to curtail P V, and reduce energy used for pre-conditioning.
For cold climate s Tesla s trongl y recommend s ins talling Pow er wall indoor s w hen possible (par ti cularly
w
hen long outages are expected).
For hot climates Tesla re co mmends keeping Po werwa ll out of dire ct sunlight. Installation in full sun
raises
the temperature inside the enclosure abo ve ambient temperature . This temperature rise is not a
safety risk, but ma y impact batter y performan ce. To optimize performance , avoid installing Po werwa ll
in loc ations that are exposed to the sun for extended periods .
Additionally , if stored in a co ld environment before installation , it ma y take several hours for Po werw all to
raise its internal temperature using pre-conditioning. Tesla recommends storing Po we rwalls in a w arm
location prior to installation to help efficiently commission and test the system.

Choose Top, Bottom, or Side Cable Entry for Backup Gateway
Determine w hether cables wi ll be routed into the Backup Gateway from the top, bottom, or side of
the enclosure. 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.
Plan the Electrical Service Connection to Backup Gateway
The Backup Gateway is service entrance rated, and can be located between the service entrance
and the main electrical panel. When installed at the service entrance, appropriate overcurrent
protection must be installed in the Backup Gateway. The Backup Gateway can accommodate t wo
different circuit breaker sizes: 100/125 A or 150/200 A
Conduit or raceway: Calculate the amount and size of conduit or raceway needed for the
installation, based on fill limits and local code requirements. With conduit, an adapter may be
required between the entry into the Po werwa ll wi ring compartment and the conduit.
Plan Distance Between Components
Follo w the table below for maximum distances between system components. Wire gauge must
meet local codes and in some circumstances wire gauge requirements change based on distance.
Refer to Appendix B for wire gauge requirements.
Maximum Cable Length
Backup Gateway to Po werwa ll(s) * 150 ft (45 m)
Neurio Energy Meter to Backup Gateway (RS485 w ired connection) 164 ft (50 m)
Backup Gateway to Internet router (wired Ethernet connection) 328 ft (100 m)
*Total length of communications cable, including daisy-chained connections, through last Po werwa ll in chain
CAUTION : Failure to follow minimum cable size and length requirements may result in
intermittent or unreliable operation of the Po werwa ll system. In systems that do not meet these
minimum requirements , performance issues may arise even after successful commissioning.
