Everything You Need to Know About Tesla’s New Household Batteries

Tesla unveiled a new product line at its design studio in LA tonight. It’s called Tesla Energy and it’s a suite of batteries for homes and for businesses. The existence of the batteries has been one of the worst kept secrets of all time. But we are here at the announcement event and finally have some details. And they’re pretty damn cool.

“Our goal is to fundamentally change the way the world uses energy,” Elon Musk said in a pre-event briefing with the press. “Which sounds crazy.”

It does sound crazy. But that’s the business Musk seems to have gotten himself into.

What are they?

The home battery is called the Powerwall. The business-targeted battery is called the Powerpack. They’re “completely sustainable, zero carbon,” as Musk puts it.

The Powerwall increases the capacity for a house with solar panels, but can also be used during power outages. It can fit on the wall in your garage—to power your Tesla, of course—or the outside wall of your house. It’s about 3 feet across, 4 ft tall, and 6 inches deep. It comes with a 10 year warranty.

It’s connected to the internet so it’s constantly talking to Tesla Energy and monitoring usage.

How much do they cost?

Tesla’s selling price to installers is $3500 for 10kWh and $3000 for 7kWh.

Business battery prices haven’t been made public as of yet.

How do they get installed?

“We’re working with certified installers for the Powerwall,” Musk said. “It’s designed to be easy to install, with two people in maybe a half an hour to an hour.”

When can I get one?

You can order the Tesla Powerwall battery now online but they’re not slated for release until late summer. The Powerpack (business version) will start to become available later this year. They’ll be making a larger push with businesses in 2016.

But that being said, they’re already out in the real world. The company partnered with SolarCity for a pilot project in California that supplied roughly 300 homes with the batteries. About a dozen Walmart stores in California and a Cargill animal processing plant have the business-grade batteries and have been testing those as well.

Tesla Energy plans to be in Germany and Australia by the end of the year. He also sees potential uses in developing countries with little access to reliable power. “In a lot of places there are no utility lines,” Musk said.

Is Musk using them at his home?

Yes, but he’s not going to be able to go completely off the grid soon.

“My house doesn’t have quite the right roof to generate enough solar power to go off the grid,” Musk said before the event. “I think it’ll probably be 2/3 solar power when it’s all said and done.”

Why does any of this matter?

By pulling homes and businesses off the grid during peak hours, America’s electrical infrastructure would see greater stability. With enough people on board (and critical mass of adoption is obviously a ways into the future) we’d likely see fewer brownouts in our cities.

Another attractive part for consumers is that this kind of battery will give homeowners complete energy independence, allowing them to sever connections to utility companies.

What are the specs for the home version?

  • Energy: 7kWh or 10kWh
  • Continuous Power: 2kW
  • Peak Power: 3kW
  • Round Trip Efficiency: >92%
  • Operating Temperature Range: -20C (-4F) to 43C (110F)
  • Dimensions: H: 1300mm W: 860mm D:180mm

Should I buy one?

Well, that depends on a lot of things. Do you have a home? Do you live in an area with a lot of sunlight? Do you have a bunch of extra cash to make an investment in clean energy? Then yes, you should definitely look into the Tesla Energy line of products.

Do they come in different colors?

They certainly do.
