Sungrow’s Testing Center Approved to Participate in UL’s Witness Testing Data Program

Witness Testing Data Program

Sungrow just announced that its testing center has been qualified by Underwriters Laboratories (UL), to participate in the UL Witness Testing Data Program (WTDP). This approval, together with those received from CSA, TÜV Rheinland, and TÜV Sud, has again proven Sungrow’s position as a technology leader in the PV inverter industry, due to the company’s global reach and versatile product lineup.

UL’s standards and certifications are known for their strict test requirements and often lengthy approval processes. The WTDP enables approved manufacturers to test PV inverters using their own labs and engineers before receiving a relevant certification. Only facilities that have the required test equipment, environmental conditions, qualified personnel and data reporting instruments are eligible to participate in this program. Sungrow’s eligibility will significantly speed up the testing and verification process, and accelerate the company’s product to market process.

Sungrow in a statement said that its testing center has been evaluated by the UL team as “a world leading testing platform under standardized and professional management, surpassing our requirements in all aspects including technology, engineer expertise, and testing ability.”

Apart from the approval, Sungrow has also reached agreements with UL on further co-operations in regards to product certifications, introducing UL standards into early-stage product designs, and providing support to UL in drafting new standards as technologies evolve.

We have always strived to provide our customers with PV inverters of the highest quality. By participating in UL’s WTDP program, we will not only acquire timely UL certifications, but also allow our newest, most innovative products to be available to our partners sooner.” said Renxian Cao, President of Sungrow.
