The GS S1 certificate is awarded to manufacturers that demonstrate full compliance with the German equipment safety law and also comply with the low-voltage directive required for CE mark labeling.

“Our close collaboration with TUV Rheinland resulted in an efficient and timely process, from initial design review through final product testing,” said Jeff Muchow, Xandex’s VP of engineering and quality. “The process was thorough, ensuring SunMizer is a safe and effective product for both the American and European markets.”
