Company Description

Sunways is a cutting-edge technology company founded in Konstanz, Germany in 1993, dedicated to developing, manufacturing, producing and distributing PV parts, including inverters for on-grid and energy storage PV systems in residential, commercial and industrial projects, data communication solutions, accessories and applications for monitoring and managing. Since the inception, we have been convinced that the energy transition from fossil fuels to renewable energy such as wind and solar is inevitable. With a strong belief in this trend, Sunways produced a series of technical-leading solar solutions, including on-grid and hybrid inverters, and dominated the solar industry in the late 1990s and millennium.
