You will need to be at home and available throughout the day of your installation. A Powerwall installation team, typically made up of two to three installers, will arrive in the morning. If you are installing solar at the same time, an additional four installers could be on site.
Installation time will depend on the size of your system and the complexity of the electrical work required. A typical Powerwall installation will take a full day to complete.
Plan for the power to be out for roughly four to six hours. If additional electrical work is required, the power could be out for up to eight hours or more. This includes refrigerators, heating and cooling systems and your home Internet connection.
If loss of power for a sustained period will be an issue, contact your installation team in advance to discuss options.
