Installation Process

What are the different components that make up a Powerwall system?

A Powerwall system consists of at least one Powerwall battery and a Backup Gateway. The Backup Gateway provides energy management, metering and monitoring functions for Powerwall. It controls connection to the grid, safely disconnecting your home and starting backup operation during an outage. The Backup Gateway also includes communication functions for up to 10 Powerwalls, and receives over-the-air updates for the system.

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 optimize 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.

What are the different options for the site survey to plan my Powerwall installation?

Your Powerwall site survey can be completed remotely using our self-survey option. This is the fastest and most convienient method for getting an estimate. You will need to complete an online form and submit photos showing the required information.

If you prefer, we can offer a professional survey and come to your home to gather the necessary information. This may delay the process and will require you to be home and provide access to the required areas.

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 propsal.

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 4 hours and possibly longer.

When can I start using my Powerwall?

After Powerwall is installed, your utility will provide a Permission to Operate (PTO). Powerwall and any newly installed solar will then be operational. Be sure to download the Tesla mobile app from the iOS or Android app store.
