It all started with one solar powered railway signal.

Sungrow was founded by Prof Cao Renxian - a teacher at the Hefei University of Technology. Upon learning of the unsatisfactory state of electrical availability in rural western China he quit his teaching position in 1997 and founded the Sungrow Power Supply Co., Ltd.

An idea whose time had come.

Prof Cao Renxian wanted to improve the availability of electricity and thereby enabled a steady economic growth in rural western China. Instead of focusing on economic growth at all costs, he opted for sustainable growth based on regenerative energy sources.

The first Sungrow client - an engineer overseeing signal power supply for the southern Xinjiang railway - ordered one solar power supply for a signal. This resulted in total company income of $87,000?in 1998.

Upon fulfilling the first test-order, more orders came in and business started picking up. Adding to the success was the fact that solar technology was an idea whose time had come.

Today, Sungrow is a more than $1.5 billion company. As a key high-tech enterprise in China, Sungrow specializes in R&D, production, sales, and service of new energy power supply devices for solar energy, wind energy, energy storage, new energy automotive drive systems, floating and land-based PV power plants. Our objective is always to provide clean power for all, today, tomorrow and beyond.

Each year Sungrow files hundreds of new patent applications. Sungrow is an absolute innovation leader in the solar industry, with more than 1,600 applications as of June 2019.
Clean power conversion technologies such as AC/DC conversion, energy route switching, energy conversion for electric vehicles, and conversion of clean energy to clean power are Sungrow’s unwavering strategic orientations.
