Installation Process

Do I need to be home during installation?

Tesla requires that you be home on the day of the installation to provide access to the installers if needed and to ensure you have full functionality and visibility on the Tesla app before the installers leave.

How long does the installation take?

Installation time will depend on the size of your system and the complexity of the electrical work required. A typical installation is completed in one full day. Depending on the complexity of the electrical work required, the power to your home will be off for a minimum of four hours and possibly longer.

Can I have a closer installation date?

Installation dates are scheduled to allow enough time for Tesla to receive full payment prior to installation, and also depends on installer availability and customer volume.

Can I get my own electrician to install the Powerwall?

If you placed a reservation through, you’ve chosen to have Tesla manage the delivery and installation of your Powerwall. This means that your installation will be completed by an installer that has a direct partnership with Tesla. Tesla oversees our direct partners to ensure that they meet strict standards of customer care and installation quality.

What does a Powerwall system look like with all the additional equipment installed?

A Powerwall installation includes at least one Powerwall battery, a Backup Gateway, and standard electrical hardware such as circuit breaker panels, conduit, junction boxes, or electrical disconnects as required by your particular installation and local electrical codes. In some cases, conduit and other electrical hardware can be hidden within the wall for an additional cost.

What does a multiple Powerwall installation look like?

Multiple Powerwalls can be mounted as single side-by-side units on a wall or on the floor, or stacked front-to-back (up to 3 deep per stack) on the floor only. When mounted side-by-side on a wall, Powerwall units must have sufficient clearance on each side for electrical connections and proper ventilation.  When stacked front-to-back, Powerwalls must be floor-mounted, the stack must be anchored to an adjacent wall, and the Powerwalls must be joined together with Powerwall Stack Kit hardware.  For stacked systems with more than 3 Powerwalls, separate stacks of 3 units should be installed, with each stack attached to a wall.

What are the environmental requirements for a Powerwall installation?

Powerwall and Backup Gateway units are rated for installation indoors or outdoors, and can operate within a wide range of temperatures, from -20°C to 50°C (-4°F to 122°F). At the high and low ends of this temperature range, Powerwall may limit charge or discharge power based on battery cell temperature to improve battery lifespan. To optimise performance, avoid installing Powerwall in locations exposed to direct sunlight or subject to sustained high or low temperatures.

While humidity and rain do not pose a risk, Powerwall should not be installed in locations subject to flooding or near water sources such as downspouts, faucets or sprinkler systems.  In order to maintain proper ventilation, Powerwall should be kept clear of debris such as leaves and dense brush, and of accumulated snow.

Will I need to upgrade my home electrical system for my Powerwall installation?

Tesla design teams will assess your home's electrical system based on your site survey and include any electrical upgrades your home may require in your proposal.

When can I start using my Powerwall?

After Powerwall together with any new solar is installed, it will be operational. Be sure to download the Tesla mobile app from the iOS or Android app store.
