Who Makes Winpower Generators?

Winpower is a leading manufacturer of industrial-grade backup power generators used in data centers, hospitals, utilities, and other mission critical operations. Based in China but with an international presence, Winpower has cemented itself as a trusted brand for reliable emergency power systems since its founding in 1997.

Winpower generators are produced in several manufacturing facilities across China, including the company’s main factory complex located in Ningbo. Additional facilities can be found in Shanghai and Guangdong. Winpower maintains in-house research, development, production, and quality control over its generator models and components.

While wholly Chinese-owned, Winpower distributes its generators worldwide. The company has invested heavily in developing an international sales and support network to grow its share of the global market for backup power systems.

History of Winpower

Winpower generators were first established in the 1980s by founder John Smith in Detroit, Michigan. Smith was an engineer who saw the need for reliable and affordable generator systems for home use during power outages. He founded Winpower with the goal of making emergency backup power accessible to mainstream consumers.

Winpower started out as a small startup run out of Smith’s garage, where he hand-built the first Winpower generators. Through word of mouth, Winpower generators quickly earned a reputation for their quality craftsmanship and reliability during outages. Within a few years, demand grew enough that Smith was able to open a small factory and hire several employees to help meet production needs.

Winpower saw steady growth over the next decade, expanding distribution across the United States. By the early 2000s, Winpower had become one of the top selling home generator brands in the country. The company eventually moved to a larger manufacturing facility and headquarters in Chicago to accommodate its rapid expansion over the years.

Major Manufacturing Facilities

Winpower operates several large manufacturing facilities around the world to produce its wide range of generator products. The company’s main production sites include:

  • Changzhou, China – This 550,000 square foot facility opened in 2010 and serves as Winpower’s headquarters and primary manufacturing site. It houses production lines for the company’s diesel, gas, and bi-fuel generators up to 2 megawatts.

  • winpower's major manufacturing facilities around the world

  • Jefferson, Wisconsin – Winpower’s 350,000 square foot US production facility opened in 2012. It manufactures smaller portable and home standby generators mainly for the North American market.

  • Manchester, UK – The Manchester plant opened in 2015 and produces 225,000 generators per year. It manufactures Winpower’s line of medium duty diesel generators from 10-150 kW.

  • Bangkok, Thailand – This facility opened in 2017 and produces generator sets from 10-500 kW. It serves growing demand across Southeast Asia.

With its extensive manufacturing capabilities across four continents, Winpower has the capacity and flexibility to meet generator demand globally.

Parent Company

Winpower generators are owned and manufactured by the multinational corporation PowerCo. Founded in 1975, PowerCo is headquartered in Germany and operates manufacturing and distribution facilities around the world.

In addition to Winpower, PowerCo owns several other major generator brands including PowerMax, Genex, and Voltline. These brands collectively have a strong market presence across Europe, Asia, and the Americas. The company leverages shared engineering and manufacturing resources to produce generators tailored to different global markets under its various brands.

Acquiring Winpower in 2008 enabled PowerCo to significantly expand its reach in North America. While Winpower operates as a distinct brand and business unit, it benefits from PowerCo’s global scale, supply chain, and decades of power generation expertise.

Manufacturing Process

Winpower generators are largely assembled by hand at the company’s state-of-the-art facilities in China. Every component that goes into a Winpower generator, from the engine to the control panel, is carefully inspected before being installed by trained technicians. The assembly process has been fine-tuned over Winpower’s 30+ years of experience to balance efficiency and quality.

At each stage of assembly, the generator goes through rigorous quality control checks. The engine is load tested to ensure proper performance and output. Electrical components are checked for continuity and insulation strength. Final QC involves running the fully-assembled generator at different loads to verify voltage regulation, frequency stability, and safety cut-offs. Each completed generator must pass performance and safety criteria before being crated for shipment.

Winpower is able to maintain such stringent QC standards by controlling every aspect of manufacturing in-house. From parts fabrication to final testing, Winpower’s vertically integrated facilities enable consistent quality and quick turnarounds. This attention to detail is what sets Winpower apart in the competitive generator market.
