Twenty-eight brand guides to the brands that power the home — portable power stations, home batteries, EV chargers and generators.

Home energy mixes old names with newer ones. These guides set out who owns each brand and where its products are made.

Who is behind the name

Several American-facing brands are Chinese companies: Jackery, credited with inventing the consumer solar generator, is quietly a Shenzhen-listed company, and Firman’s generators are owned by China’s SUMEC group and made in Nanjing. Westinghouse generators carry an 1886 trademark licensed to a separate maker. Goal Zero, whose Yeti stations grew from a humanitarian project in the Congo, now belongs to BioLite, and Sonnen has been owned by Shell since 2019.

Market turbulence

The category has had casualties. SolarEdge closed its energy-storage division in 2024; JuiceBox’s operator, Enel X Way, left North America the same year; and Easee was at the centre of a reported 2023 Swedish safety ban. Generac, by contrast, is an independent 1959 Wisconsin company that dominates the home-standby market and genuinely manufactures.

How to use these guides

Each guide covers who owns the name today, where the products are made — by the maker’s own account and, where it differs, by other sources — and the brand’s visual identity. A company’s description of itself is attributed to the company, and where a business has closed we say so plainly. The table at the end gathers the essentials.
