Sungrow Power Supply Co., Ltd.

Sungrow Power Supply Co., Ltd. is a Chinese multinational specializing in renewable energy power conversion equipment, headquartered in Hefei, Anhui Province. Founded in 1997 by Professor Cao Renxian, the company is the world's largest photovoltaic inverter manufacturer and a global top-tier energy storage systems provider, listed on the Shenzhen Stock Exchange under ticker 300274. In 2025 Sungrow generated RMB 89.18 billion in revenue with net profit of RMB 13.46 billion, shipped 143 GW of PV inverters, 43 GWh of storage systems, and 63 GW of wind converters, and employed roughly 19,000 people globally.

Company Overview

Sungrow's product family spans the full renewable energy power chain. Its central inverter platforms — with ratings up to 3.125 MW — anchor utility-scale solar plants across China, the Middle East, Europe, and emerging markets, while its string inverters serve commercial rooftops and residential installations worldwide. The company's energy storage business has become its fastest-growing engine: in 2025 ESS shipments reached 43 GWh, generating RMB 37.3 billion of revenue, with liquid-cooled utility-scale containers, commercial cabinets, and residential hybrid systems supported by proprietary battery management software and grid-forming control technology. Beyond solar and storage, Sungrow manufactures wind power converters (63 GW cumulative), electrolyzer power supplies for green hydrogen, and EV charging hardware that increasingly ships with integrated solar-storage-charging architecture.

Overseas expansion has transformed Sungrow's financial profile. In 2025 more than 60% of revenue came from international markets, with high-margin demand in Europe, the Americas, the Middle East, and Southeast Asia lifting gross margin to 31.83% and net profit to RMB 13.46 billion. To serve these markets while hedging tariffs, Sungrow operates four manufacturing bases — including factories in India and Thailand — and seven R&D centers, giving it a truly regionalized production footprint and the ability to localize products for grid codes from Germany to Brazil.

Key Strengths

Unmatched scale in PV inverters. With 143 GW shipped in 2025, Sungrow has held the global number-one position in PV inverter shipments for many consecutive years, giving it procurement scale on IGBT and SiC power semiconductors and a vast installed base that drives service and replacement revenue. Storage leadership with vertical integration. Sungrow designs its own PCS (power conversion systems), BMS (battery management), and EMS platforms, and works directly with LFP cell partners, enabling tight cost control and fast innovation cycles in utility-scale ESS. R&D intensity. More than 40% of the workforce — 7,625 engineers — works in R&D, with CNY 4.18 billion invested annually, supporting advances in wide-bandgap devices, 10+ MWh storage containers, and grid-forming inverters. Financial strength. RMB 13.46 billion net profit and strong operating cash flow give Sungrow the balance sheet to fund overseas plants, pre-invest in capacity, and weather solar-market downturns.

Sungrow has also begun to extend beyond renewables into computing infrastructure. In its 2025 annual report the company explicitly outlined an AIDC (AI Data Center) power strategy, targeting the high-efficiency power conversion and energy storage systems that AI campuses require — positioning itself alongside Eaton, Vertiv, and Delta in the emerging AI power market while retaining renewable dominance.

Risks & Outlook

Sungrow's principal risks are cyclicality and geopolitics. Global solar installations and storage deployments remain sensitive to interest rates, subsidy policy, and grid connection queues; a slowdown in key markets such as Europe or the US would directly pressure inverter volume. Trade policy is a second exposure: anti-dumping and tariff actions against Chinese power electronics in the US and Europe could erode overseas gross margins, though local manufacturing in Thailand and India mitigates some of this risk. Competition within China — from Huawei Digital Power, Growatt, and GoodWe — keeps domestic pricing disciplined.

The outlook is nevertheless constructive. Global energy storage is entering a multi-year super-cycle as grid operators add batteries to firm up renewables, and Sungrow's 43 GWh shipment base positions it to capture a large share. The company's expansion into grid-forming technology, hydrogen power conversion, and AI data center power also diversifies its growth vectors beyond solar. With a fortress balance sheet, a globalized footprint, and category-leading inverter share, Sungrow remains one of the highest-quality names in the global power electronics ecosystem.
