String-Level Arc Protection
The Fonrich String-Level Arc Protection Solution is an electrical arc protection system designed for large-scale photovoltaic (PV) solar plants. This device is installed at string level (solar panel strings) and enables immediate detection and disconnection in the event of electrical arcs, preventing fires, equipment damage, and protecting the environment.
It is especially designed to prevent fires in large-scale solar stations, minimizing risk in forest areas, agricultural land, and other sensitive locations.
Available in two models:
FR-AFCI-KNJA (PLC communication)
FR-AFCI-KNJW (LoRa communication)
Main Functionalities
- Real-time detection of electrical arcs in photovoltaic strings
- Automatic protection against arcs, preventing fires or damage to solar systems
- Remote monitoring via SafeSolar cloud platform or local interface
- Flexible configuration to suit the number of strings in the project
- High durability and reliability, thanks to IP68 protection and compatibility with 1500V systems
Advantages
Effectively addresses arc issues in ground-mounted PV systems by enabling arc fault detection and shutdown at string level. When an arc is detected in a string, the system performs a string-level shutdown.
Fire Safety
Prevents fires by detecting arcs and cutting off the circuit to protect equipment and infrastructure.
Smart Monitoring
Provides real-time data and alarms through the SafeSolar cloud platform for quick intervention.
Flexible Integration
Adapts to different string configurations, making installation easy in any solar project.
Extreme Durability
IP68 protection ensures resistance to dust, water, and operation in extreme temperatures.
Risk Reduction
Minimizes the risk of fire spreading to forests, fields, or other sensitive environments.
Versatile Communication
Offers both PLC (wired) and LoRa (wireless) communication options for seamless integration.
String-Level Arc Protection, Performs Best Alongside
- Smart PV PLC Transceiver
Control of the safety protector module is achieved through PLC signals, and the information is transmitted to the monitor via RS485.
- PV module rapid shutdown meeting NEC 2017,2020 and 2023(690.12) requirements
- Bidirectional PLC communication with smart Pv safety protection device
- Modbus RS485 port to connect with monitor
- Non electrical contact with PV cable, safe and easy installation
- Max support 24 PV strings, and 624 PV modules
- DC Arc Protection Box
The PV Arc Protection Box is a comprehensive intelligent protection device developed in response to the lack of detection and protection for DC arc faults in distributed photovoltaic power stations, integrating detection, protection, and early warning functions for DC arc faults to enhance the safety and reliability of power stations.
- SafeSolar Cloud
The Fonrich SafeSolar Cloud Platform is an intelligent management system that, leveraging expertise in photovoltaic safety, offers a professional platform for PV industry participants. It ensures system safety by monitoring generation, power, voltage, temperature, and detecting arc faults.
Users can remotely manage PV modules via smartphone, tablet, or PC, accessing system generation data anytime, anywhere, and receive remote technical support to enhance photovoltaic safety.
