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.
Main Functionalities
- Accurate detection of string DC arc.
- Max. 16 channel arc detection.
- RS485/Modbus RTU communication.
- Support for extended DTU networking remote monitoring.
Advantages
Upon detection of a fault arc, an immediate alarm signal is sent via the local indicator light. Simultaneously, the switch quickly disconnects the inverter from the PV DC string. This ensures the PV DC string loop is de-energized rapidly, effectively extinguishing the arc. This patented arc extinguishing technology by Fonrich does not disrupt normal power generation while significantly protecting property and preventing personal injury, completely mitigating photovoltaic fire risks.
High Compatibility
Offers wide compatibility with leading inverters, integrating AFCI functionality at a significantly lower cost.
Arc Fault Detection
Patented photovoltaic DC arc extinction technology maintains normal power generation, preventing contact damage, electrical equipment failure, and fires for stable power station operation.
High-quality Design
IP66 rated for excellent protection against dust and powerful water jets. We deliver solutions with exceptional user experience and enduring durability.
Remote Monitoring
Enables continuous remote monitoring through extended DTU (Data Transfer Unit) networking, facilitating enhanced data collection and transmission for remote analysis and system management.
Standardized Design
Monitors and detects arc faults across up to 16 channels, engineered for effective operation at 1100V.
Reliable Data Transfer
Integrates RS485/Modbus RTU for reliable and efficient data communication, ensuring seamless integration for industrial automation and control.
