Tesla focuses on smaller, daily-use batteries for homes

When it comes to batteries, homeowners apparently don’t need as much energy storage as Tesla Motors thought they did.

Tesla Motors says it will concentrate only on developing its 7-kilowatt-hour Daily Powerwall battery, which is intended for everyday use but also has backup power capabilities.

Last April, the Palo Alto-based company announced that it would produce two batteries: the $3,500 Tesla Powerwall, intended to store 10 kilowatt-hours of backup power, and the smaller, $3,000 Daily Powerwall battery.

The batteries make the most sense for homeowners with solar panels, since excess energy generated by their systems can be stored for use during the night or on cloudy days. That backup power option would allow connected appliances, lights or computers to run during outages.

But the need for more storage is less obvious. Under so-called “net energy metering” policies, rooftop solar owners can sell power they don’t use back to the utility companies.

Tesla said it never produced the 10 kilowatt-hour batteries.

“We have seen enormous interest in the Daily Powerwall worldwide,” Tesla said in a recent statement. “Due to the interest, we have decided to focus entirely on building and deploying the seven kilowatt-hour Daily Powerwall at this time.”

The news was first reported by Greentech Media.
