Mercedes-Benz is getting into the home energy storage business in the U.S. The German automaker announced today plans to collaborate with solar provider Vivint to offer its battery expertise for in-home energy storage. The move is apparently an attempt for Mercedes to compete with Tesla and its Powerwall.
Last year Mercedes-Benz parent Daimler AG announced a new subsidiary of the company dubbed Mercedes-Benz Energy. This subsidiary of the company is the one teaming up with Vivint and its first move in the U.S. market.
“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, LLC. “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.”
Basically the partnership will enable Vivint to offer Mercedes-Benz lithium-ion batteries to pair with its solar technology for in-home use. Customers with Vivint panels on their roof will then be able to store energy gathered from the sun during the day to use during the night, when commercial electric rates are typically higher. Each Mercedes-Benz battery has 2.5-kWh of storage, but owners can scale them up to 20-kWh for larger homes.
In comparison, the Tesla Powerwall features 14-kWh of storage, which is about half the average power consumption of a typical three-bedroom home. A Tesla Powerwall costs just over $6,000 with required hardware.
Mercedes-Benz nor Vivint has offered up what the cost of the battery will be for homeowners.
