Sunways proudly announced the successful attainment of the IEC 62109 certification for its new STT-100-150KTL-SE inverter. The certification ceremony, held on May 7 during Intersolar Europe 2025, was attended by distinguished guests, including Louis Kang, Renewable Director at DEKRA and Ken Zhu, CEO at Sunways.

The STT-100-150KTL-SE inverter is a robust solution tailored for commercial and industrial applications, addressing the growing demand for efficient and secure energy management. Equipped with advanced Arc Fault Circuit Interruption (AFCI) technology, it actively detects and mitigates potential arc faults, significantly reducing fire risks and enhancing long-term system safety. Its intelligent anti-reverse flow function dynamically manages power generation to prevent current from feeding back into the grid, ensuring compliance with strict grid connection requirements.

Designed for flexibility, the inverter supports multi-unit parallel connection, making it well-suited for businesses aiming to expand rooftop installations while optimizing initial investment costs. With features such as remote upgrades and 24/7 monitoring, the STT-100-150KTL-SE enables real-time diagnostics and rapid fault resolution, helping to lower maintenance expenses and boost system reliability. Furthermore, it accommodates high-current components, supporting single-string input currents of up to 20A to maximize energy yield and enhance overall power generation.

The certification from DEKRA reinforces Sunways' commitment to developing safe, reliable, and high-performance solutions to meet the evolving needs of global energy markets.

As the global solar market continues to grow, Sunways will leverage its strong technological foundation and international perspective to accelerate its global strategic expansion. Looking ahead, the company remains dedicated to driving solar technology toward greater efficiency and intelligence, contributing its expertise to the creation of a cleaner, low-carbon energy future.
