SunLink’s TechTrack Distributed single-axis tracker is now ETL certified to the UL 3703 standard. This certification was secured after independent review and rigorous safety testing by Intertek to meet the industry’s highest standards for solar tracking system functions with regard to risk for electrical, mechanical and fire hazards. Intertek, a Total Quality Assurance provider, is a Nationally Recognized Testing Laboratory approved by the U.S. federal agency Occupational Safety and Health Administration (OSHA).

Last year TechTrack Distributed achieved its ETL classification to UL 2703, which required rigorous safety testing such as humidity and temperature cycling to ensure all components remain properly bonded in outdoor environments. The recent testing to UL 3703 included a complete construction evaluation of the system and performance testing to ensure safe operation. TechTrack Distributed’s maximum system voltage of 1500V is also covered by the UL 3703 certification.

“TechTrack Distributed is the most technologically-advanced tracker on the market today designed to maximize generation potential,” said Michael Maulick, president and chief executive officer of SunLink. “Attaining certification to the UL 3703 standard is testament to our engineering heritage and prowess that created the industry’s most advanced tracker system combining structural, electrical, mechanical and software applications.”

Central to TechTrack Distributed’s system innovation is a dynamic design feature called Dynamic Stabilization. Beyond simply adjusting tilt, SunLink’s TechTrack Distributed incorporates real-time control over the damping and stiffness of the array, opening a completely new solution space for increasing energy output, maintaining structural integrity and lowering cost.

In addition, TechTrack Distributed solves the challenge associated with monitoring the thousands of distributed trackers with SunLink’s VERTEX Project Intelligence Platform. VERTEX enables next-generation data monitoring and secure remote control, which provides greater visibility into energy assets, historical data collection and more efficient O&M — resulting in more valuable energy projects.
