Utilities throughout the U.S. 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, we have developed Tesla Backup Switch.

Tesla Backup Switch is a component in a Powerwall system that facilitates backup power functionality by quickly and safely disconnecting your home from the grid when a power outage is detected. The system then automatically shifts your home’s energy use to backup power from your Powerwall. Backup Switch can be installed in whole home backup systems and cannot be installed in partial backup systems. Backup Switch can also be installed as part of a Powershare Home Backup system.
