How do I install a Tesla Powerwall 2?

To install a Tesla Powerwall system, you must ensure that the Islanding Controller (or Backup Gateway 2, or Powerwall+ if applicable) is connected to the internet. Once the system is energized, use the Tesla mobile application and follow the path ‘Energy Field Work’ > ‘Tesla Device Setup’ to configure your Powerwall.

Is it possible for me to install a Tesla Powerwall on my own?

Installing a Tesla Powerwall requires a certified professional. The system, which includes a Backup Gateway or Backup Switch, is designed to power your home during grid outages. When paired with solar panels, it can store excess solar energy for use when there is no sunlight. For safety and compliance, a Tesla Certified Installer must perform the installation.

Do I need a gateway to install a Powerwall 2?

Yes, a gateway is required for the installation of Powerwall 2. This gateway acts as a relay between your solar system and the Powerwall, ensuring that when the grid is down, your solar system can still charge the batteries without sending energy back to the grid. The installation of a gateway is a code requirement to manage the flow of power and isolate your home’s power from the grid.

Can the Tesla Powerwall 2 be installed both indoors and outdoors?

The Tesla Powerwall 2 can be installed both inside and outside your home. Tesla recommends indoor installation in cold climates, especially if long power outages are expected. In hot climates, it is advised to avoid direct sunlight by keeping the Powerwall in a shaded area. Direct sunlight can increase the temperature inside the Powerwall’s enclosure beyond the ambient outdoor temperature.
