Mercedes-Benz is bringing its energy storage business to the U.S. through a partnership with residential solar company, Vivint Solar.

The collaboration pairs the German brand’s energy storage division with one of the U.S.’ largest home solar companies, and Mercedes-Benz says it sees a new market segment to serve, plus a good way to promote its electrified vehicle offerings.

Those purchasing the energy storage system will get modular 2.5 kWh batteries that can be combined to go as high as 20 kWh of stored power. Vivint Solar will be on hand at the installation to customize the homeowner’s setup based on their energy consumption.

For homeowners with solar power, the collaboration will provide them with more control over managing electricity costs and providing backup power if the grid goes down. For owners of electric Mercedes models, tapping into clean energy can be guaranteed by charging up through stored solar power.

For Mercedes electric car owners, such as those driving the B-Class Electric Drive or the future EQ models, power will be coming from their solar panels no matter what. For those concerned about having to charge their cars on the grid when their solar power runs out, or during emergency power outages, they can be assured they can always go off the grid.

“As Mercedes-Benz electrifies its vehicle fleet, solar plus storage is essential to enable those vehicles to be powered by clean energy,” said Boris von Bormann, CEO of Mercedes-Benz Energy Americas. “With batteries featuring the best in automotive engineering from Mercedes-Benz, and high-quality solar energy systems from Vivint Solar, our solution allows customers to take the next step toward a sustainable energy future. The launch of our home battery system in Europe has been successful and we are thrilled to be working with Vivint Solar to bring a reliable and compelling solar plus storage offering to American homes.”

Earlier this month, Mercedes-Benz Energy staked its claim to the U.K. market through energy storage aimed and home and business owners. Homeowners will have the same backup capacity as in the U.S., and commercial customers are being given access to more power storage.

Parent company Daimler started the energy storage division in 2015 soon after Tesla Energy was launched. BMW and Nissan have also started up energy storage businesses.

Advocates of solar energy, and other renewables such as wind, for years have been hoping that energy storage systems will come to market that can alleviate the instability of fluctuating weather patterns. Beyond hours of available sunshine, rainstorms and cloud covers can take away some of the available energy going to solar panels.

Tesla is going this route through its Tesla Energy unit and SolarCity subsidiary. Powerwall units are able to store enough solar energy to continue keeping homes lit up and Tesla vehicles charged when sunshine goes away.

As for keeping energy costs down, Vivint Solar will help customers better manage their consumption. For those living in power zones with time-of-use electricity rates, users can store excess solar energy for consumption when energy costs shoot up, such as during nighttime.

Some electric utilities are also willing and able to purchase renewable energy from other sources such as home and business owners with stored solar power. That can reduce energy costs and provide them with an additional revenue stream.

Vivint Solar and Mercedes-Benz Energy will start this service in the California market.
