Fonrich (Shanghai) New Energy Technology Co., Ltd. Selected as a Third Batch Smart PV Demonstration Enterprise by the Ministry of Industry and Information Technology of China

In order to further promote the deep integration of the photovoltaic industry with next-generation information technology and to advance intelligent photovoltaic technology and industry applications, the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, the Ministry of Transport, the Ministry of Agriculture and Rural Affairs, and the National Energy Administration have decided to organize the third batch of intelligent photovoltaic pilot demonstration activities. This decision aligns with the objectives of the “Intelligent Photovoltaic Industry Innovation and Development Action Plan (2021-2025)” (MIIT Electronics [2021] No. 226).

The initiative aims to cultivate a batch of intelligent photovoltaic demonstration enterprises capable of providing advanced and mature intelligent photovoltaic products, services, system platforms, or comprehensive solutions. Additionally, it seeks to establish a series of intelligent photovoltaic demonstration projects that integrate smart photovoltaic products with new-generation information technologies such as 5G communication, big data, industrial internet, and artificial intelligence to offer smart photovoltaic services to users.

This time, Fonrich New Energy, leveraging over a decade of technical and practical experience, has become the only enterprise in Shanghai to be selected for both a demonstration enterprise and a demonstration project.

Founded in 2011, Fonrich New Energy has consistently focused on the photovoltaic new energy sector, driven by technological innovation. Its product range includes intelligent photovoltaic module-level safety protection systems, intelligent optimization systems for photovoltaic modules, DC arc fault detectors, and intelligent monitoring of photovoltaic combiner boxes. The company is dedicated to providing products and solutions that optimize photovoltaic new energy yields, enhance power station safety, and enable intelligent operation and maintenance management.

Fonrich’s intelligent photovoltaic safety protection system, based on IoT concepts, offers module-level safety protection and digital management systems for distributed photovoltaic power stations. It features an industry-leading “four-in-one” protection functionality: rapid shutdown protection, string disconnection protection, module-level arc protection, and intelligent monitoring. The system can automatically activate, disconnect, isolate, or reduce the voltage, current, and energy output of photovoltaic modules to the photovoltaic system.

With high-speed bidirectional PLC communication, the system displays data through an LCD screen. It complies with NEC 2017 and 2020 (690.12) standards. One monitor and one PLC transceiver correspond to each inverter in the photovoltaic power station, with a single PLC transceiver connecting up to 512 protectors. Backed by 25 IP patents, the IoT gateway can connect to the cloud via WIFI, RJ45, or 4G, significantly reducing costs compared to other products of the same capacity.

Fonrich’s intelligent photovoltaic module safety protection system’s robust design makes it suitable for high-safety requirement distributed photovoltaic applications in homes, factories, gas stations, office buildings, and other settings.

Comprehensive Safety Protection with Four-in-One Design

Fonrich’s intelligent photovoltaic module safety protection system focuses on extreme safety design with industry-leading rapid shutdown safety protection. It also features two exclusive protection technologies and an intelligent system for proactive warnings, ensuring comprehensive system safety.

Rapid Shutdown Protection: Utilizing Fonrich’s module-level technology, each photovoltaic module’s connection can be remotely or manually shut down quickly. Within 30 seconds, the photovoltaic array’s equipment within 30cm stops working, or the system voltage drops below 30V, eliminating high DC voltage risks in the array and resolving rescue risks in photovoltaic power stations.

String Disconnection Protection: In case of a string disconnection fault, all safety protectors in the faulty string enter shutdown mode within 5 seconds, preventing accident escalation.

Module-Level Arc Protection: Ensuring the safe operation of the power station is critical for rooftop distributed photovoltaics. Fonrich’s smart safety protection device integrates smart arc protection, including automatic detection, protection, self/manual reset, warning, and precise fault location. When a DC arc fault occurs, it swiftly extinguishes the arc, safeguarding personal and property safety.

Intelligent Technology Monitoring: Featuring PLC bidirectional communication, it collects real-time data on voltage, current, power generation, operating points, and temperature, uploading snapshots to the server. AI-based power station diagnostics, data analysis, and historical queries provide multi-level protection and 100% accurate fault component location, significantly reducing power station management costs.

Quality Assurance and Reliable Performance

With a DC input current of up to 25A, the system is compatible with most 182 and 210 modules, creating multiple industry firsts.

It boasts an IP68 protection level, meeting various application needs, and its new craftsmanship ensures stable operation in environments ranging from -40°C to +75°C. Enhanced with over-temperature detection, it effectively prevents hazards, offering a system lifespan of up to 25 years.

Since its launch, Fonrich’s smart photovoltaic module safety protection system has been widely applied in industrial and commercial distributed photovoltaic projects, including high-safety standard projects like gas stations, office buildings, and factories, as well as convention centers, high-speed rail stations, and other densely populated areas. In the future, Fonrich’s intelligent photovoltaic module safety protection system will be prevalent across various industries and scenarios, including manufacturing, county-wide residential use, and zero-carbon parks.
