About Sunways

German design & efficiency since 1993, the Sunways range of inverters only use best in the class components and a unique design which provides optimal performance and reliability. Backed by an industry leading 12 Year Warranty at a price point that will impress you, Sunways inverters are the number one choice for those looking for quality and affordable solar inverters for their residential or commercial solar system.

With Suntech backing the brand and taking care of all technical and warranty aspects of the Sunways product, customers can have peace of mind knowing that they are covered if any issues arise.
