TUV Rheinland certifies Xandex DC power optimizer for solar PV panels to UL, GS standards


Xandex’s solar division said that TUV Rheinland of North America has certified its SunMizer DC power optimizer for photovoltaic panels to U.S. and European safety standards. The testing lab certified the device to both the UL 1741 and GS S1 requirements.

UL 1741 is the U.S. safety standard for inverters, converters, charge controllers, and interconnection system gear intended for use in stand-alone or utility-interactive solar power systems.

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.”
