Storage and project activity in 2026

Sungrow's 2026 announcements concentrate on battery storage and grid support. On 17 September 2026 the company signed a framework agreement with the German EPC provider be.storaged covering joint battery storage projects with a planned volume of up to 1.6 GWh, in which Sungrow will increasingly deploy PowerTitan 3.0. On 15 September 2026 it marked 1 GWh of storage cooperation with ERS Energy across Southeast Asia, and on 25 August 2026 it described a 200 MW/400 MWh storage project delivered with its full-chain intelligent delivery process. On 16 September 2026 the company reported reproducing and suppressing wideband oscillation at a 500 MW plant, which it called a world first, and on 4 September 2026 it began an AI-enabled community energy project in the Southern Highlands of New South Wales with the University of New South Wales. Product news during the period includes the Benelux launch of PowerHarbor home systems, the MGTL residential and small commercial series, and regional summits in Mexico and Chile.

Service network and regional organisation

Sungrow serves customers through a network of subsidiaries and service mailboxes rather than a single global desk. The contact page lists local service addresses for Thailand, Malaysia, Vietnam, Pakistan, Indonesia, Japan and Korea, a European organisation covering Benelux, Denmark, Sweden, Norway, Finland, Greece, Israel and the United Kingdom, an Americas unit with a Latin America service address, a Gulf and Middle East support line, plus Sungrow Australia and Sungrow India. The headquarters service line is reachable on +86 400 119 7799. Media enquiries go to [email protected], and privacy and information security questions have their own published addresses.

Position in the supply chain

Sungrow sells equipment rather than owning generating assets, which places it in the equipment supply tier of the solar and storage value chain, alongside module makers and battery cell producers. Its customer base includes utilities, independent power producers, engineering contractors and distributors, and its growth is tied to the pace of inverter and storage deployment in China and overseas markets. The company does not publish English-language financial statements on its global site; results are filed with the Shenzhen Stock Exchange, and its investor pages collect the group's reporting, corporate governance material and stock information.
