Fonrich AFD Module: Core Technology for Safety Detection Solutions

As safety requirements for photovoltaic systems continue to rise and regulations are gradually implemented worldwide, inverters must be equipped with Arc Fault Circuit Interrupter (AFCI) functionality. Integrating AFCI not only ensures compliance with industry safety standards but also helps customers mitigate operational risks of photovoltaic systems, providing a more reliable and safer user experience.

Fonrich AFD Module: A High-Performance Arc Detection Device

The Fonrich AFD (Arc Fault Detector) module is a high-performance arc detection device independently developed by Fonrich. It integrates multiple core patented technologies of Fonrich, demonstrating excellent innovation and reliability. The AFD module provides a strong guarantee for the safe operation of photovoltaic DC systems.

Milestone Achievements：

High Market Recognition: As of October 2024, Fonrich AFD modules have shipped over 500,000 units, covering more than 80 inverter brands worldwide and being favored by industry customers.

Leading Industry Certifications：

· 2017: Fonrich became the first company in China to pass the UL 1699B certification, a key technical standard in the field of DC arc fault detection, demonstrating Fonrich’s leading strength in arc detection technology.
