Fonrich Smart Combiner Box Monitoring System: The Nervous Center for Large-Scale Solar Plant Safety and Efficiency

15 Oct 2025  by Fonrich New Energy   
Shanghai - As the solar power industry scales up, the efficiency of operations and maintenance (O&M) for existing plants and the integration of intelligence in new projects have become critical challenges. Fonrich New Energy, a pioneer in smart energy solutions, has recently introduced its smart combiner box monitoring system, offering a comprehensive solution for the safe and efficient operation of large-scale solar power plants.

 

Industry Challenges: The Struggle with Conventional O&M

Industry data reveals that over 60GW of ground-mounted solar power plants in China have surpassed the five-year operational mark, facing three major O&M challenges: performance degradation of key components, declining stability of communication systems, and increased risk of DC arc faults. These issues not only compromise the safety but also the efficiency of power generation.

Innovative Solutions: Fonrich's Cutting-Edge Technology

Fonrich's smart combiner box monitoring system addresses these challenges head-on. Featuring advanced technologies such as Arc Fault Circuit Interrupter (AFCI) and real-time monitoring, the system enhances safety and efficiency. Its compatibility with multiple versions of Modbus-RTU register tables ensures seamless integration during equipment upgrades, eliminating the need for backend system reconfiguration.
