Amid the global energy transition fueled by carbon neutrality, photovoltaic (PV) power has become a core clean energy source, with global new installations reaching 495GW in 2024—over half from China. However, rapid expansion raises critical safety risks, particularly DC arc faults in PV systems: high-voltage, non-self-extinguishing arcs from wiring issues or aging equipment easily cause fires, while traditional protection devices lack effectiveness.
International regulations (U.S. NEC 2023, IEC 63027, UL 1699B) now mandate DC arc protection, with China updating standards accordingly. YAS’s innovative embedded AFCI & RSD solutions address gaps: AFCI uses a custom ASIC chip and CNN algorithm for 99% detection accuracy, zero false alarms, and 2.5-second response; RSD enables rapid high-voltage unloading. Offering independent core technologies, superior performance, and low integration costs, these dual-protection solutions fit household/commercial PV scenarios, safeguarding the industry’s safe development and global green energy transition.
