On May 7, 2025, at Intersolar Europe 2025 in Munich, Germany, Fonrich New Energy, in collaboration with TÜV Rheinland, officially launched the Arc Fault Circuit Interrupter (AFCI) Solutions White Paper (hereinafter referred to as the White Paper). Focusing on DC arc detection and protection in photovoltaic systems, the document provides cutting-edge technical references for the global PV industry and enhances systematic understanding of DC arc risks.
The International Energy Agency (IEA) predicts that by 2050, clean energy will account for 75% of the global energy mix, with solar PV contributing over 30%. However, the large-scale development of the PV industry also brings systemic safety challenges, particularly the issue of DC arcs, which has become a critical technical bottleneck affecting the stable operation of PV power plants.
The “White Paper” delves into the core principles, key technologies, evolving standards, and typical application cases of DC arc detection and protection in PV systems. It systematically outlines the current technical challenges and development trends in the industry.
The “White Paper” highlights that arc protection devices monitor current and voltage characteristic signals in circuits, accurately identifying arc-specific waveform patterns. Upon detecting anomalies, they swiftly issue protective commands to interrupt the arc cycle, preventing accidents from escalating and enhancing the intrinsic safety of system operations.
The release of the “White Paper” marks a new phase for Fonrich New Energy in the field of DC arc protection technology. It not only summarizes existing technical achievements and demonstrates a profound understanding of safety standards in the renewable energy sector but also serves as an active call for advancing the safety standard framework in the industry.
Fonrich New Energy remains committed to driving the sustainable development of the PV industry through professional expertise and practical solutions, providing a solid foundation for building safer and more reliable photovoltaic systems.
