Sonnen, Inc.

What Sonnen, Inc. does

Sonnen, Inc. is the US operating subsidiary of sonnen Holding GmbH (itself a Shell plc company since the 2019 acquisition), headquartered at Stone Mountain, Georgia, with German manufacturing operations in Wildpoldsried. The company designs and sells residential and commercial lithium iron phosphate (LFP) battery storage systems, including the sonnenHome Battery 11, sonnenCore+, sonnenEvo, and the commercial ecoLinx 100, all backed by an industry-leading 10-year/10,000-cycle warranty. Its proprietary battery management system and the sonnenVPP software platform aggregate distributed home and commercial batteries into Virtual Power Plants that deliver grid services, demand response, and customer bill optimization.

The go-to-market model combines a certified installer partner network for hardware sales and installations with utility-program partnerships that supply upfront incentives and ongoing VPP revenue to enrolled customers. Customers are acquired through three principal channels: (1) the certified installer channel, where installers enroll customers into managed VPP programs and receive profit share from grid services participation; (2) utility partnership programs such as San Diego Community Power (up to $10,000 upfront incentives), National Grid and Eversource's ConnectedSolutions (peak demand response in New England), and the SOLRITE Energy Texas battery-only VPP program ($20/month for 60 kWh, targeting 10,000+ customers by end of 2026); and (3) community-development projects such as the Edmonton Blatchford Lands 100-home VPP in Canada.

Revenue is generated through three streams: hardware sales of battery systems, recurring subscription and grid-services revenue sharing from VPP participation (40% of grid-services profit to customers, with partners earning half the remainder for up to 10 years), and managed-services revenue from utility-program incentive structures. Sonnen's products are deployed across the United States (notably California, Texas, New England, San Diego, and the Southeast), Canada, the Caribbean, Central America, and Mexico, with over 125,000 systems installed globally since the company's 2010 founding.
