Tesla Backup Switch

Tesla Backup Switch is a new component in the Tesla Powerwall system that facilitates access to backup power. Backup Switch quickly and safely disconnects your home from the grid when a power outage is detected, automatically shifting your home’s energy use to backup power drawn from your Powerwall.

Backup Switch can be installed in whole home backup systems, not in partial backup systems. Tesla Backup Switch may not be approved by some utilities.

Why Backup Switch and Key Benefits

  • Faster Powerwall Installation: Use of Tesla Backup Switch cuts Powerwall installation time from eight to ten hours down to about one hour
  • Sleek Aesthetics: Backup Switch slips seamlessly behind your utility meter and can be installed with fewer additional electrical components compared to standard Powerwall installations

Grid Outages

Utilities throughout the US have experienced unprecedented reliability challenges over the past several years. Extreme weather conditions resulting in longer grid outages have left hundreds of thousands of customers without power for days at a time.

In response to this reality, and the resulting increase in demand for backup power, Tesla has developed Backup Switch technology. Tesla Backup Switch streamlines deployment of Tesla Powerwall, so customers can more easily access solutions to safeguard their homes and families during outages.
