Tesla has quietly removed references to the Tesla 10 kWh Powerwall for residential backup from the company’s website leaving the daily-use 7 kWh Powerwall as the remaining option.
A Tesla spokesperson tells Greentech Media via email, “The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home. Due to the interest, we have decided to focus entirely on building and deploying the 7-kilowatt-hour Daily Powerwall at this time.”
The 10 kWh option was promoted as a backup power supply that could be used in lieu of a generator. It was designed to have a lifespan of 500 cycles and cost $3,500. These numbers don’t work out to be of much value considering modern backup generators cost far less.
