NEXTracker’s self-powered tracker (SPT), NX Horizon, is now UL 3703 certified. This certification specifically addresses solar tracking system functions with respect to risk of electric shock, mechanical and fire hazards.
NEXTracker’s UL 3703 certification includes grounding through existing structural components without the need for additional dedicated grounding components like braids, straps or grounding washers. Evaluation included rigorous humidity and temperature cycling, rain tests and safety testing for the electromechanical systems for NX Horizon’s unique self-powered controller. The certification also covers NX Horizon’s maximum system voltage of 1500V.
“Our mission as a company is to advance the power plant of the future,” said Alex Au, NEXTracker Chief Technology Officer. “UL 3703 certification enables us to do just that. I’m proud of our incredibly talented team of engineers who worked hard to ensure that NX Horizon satisfies the most stringent safety certification for solar trackers.”
For the US solar industry, UL 3703 enables county building inspectors and other AHJs (authorities having jurisdiction) to speed up third party evaluation processes, which can also mean faster commissioning for utility-scale solar projects from Hawaii to North Carolina.
