Introduction
Fonrich Safety Protector (RSD) is a state-of-the-art rapid shutdown device designed for solar PV systems, ensuring compliance with NEC rapid shutdown requirements while delivering module-level safety and intelligence. As a leading rapid shutdown initiation device, it provides both automatic protection and manual rapid shutdown capabilities, making it an essential component of any photovoltaic rapid shutdown system.
Key Features
Module-Level Rapid Shutdown & Safety
Module-level rapid shutdown ensures each solar panel can be individually controlled in case of emergency or maintenance.
Detects and extinguishes series and parallel arc faults instantly, preventing fire hazards.
Complies fully with NEC 2017, 2020 & 2023 (690.12), UL 1741, and UL 3741 standards.
Supports rapid shutdown of PV systems through both automatic triggers and manual rapid shutdown button activation.
Communication & Monitoring
Built-in Power Line Communication (PLC) transceiver supports up to 1600m communication distance.
Enables module-level data monitoring, including real-time voltage, current, power, and temperature snapshots.
Offers 2D & 3D module-level data display, multi-module data comparison analysis, and smart fault analysis for enhanced operation and maintenance.
Durability & Installation
IP68-rated enclosure for all-weather reliability.
Supports max. system voltage up to 1500Vdc.
Designed for PV rail installation (not module frame).
Customizable rapid shutdown initiation device wire size and cable specs with MC4 connectors.

Key Difference: 1-to-1 vs. 1-to-2 Configuration
The FR-PVMS-TF Series utilizes a 1-to-1 configuration, meaning one RSD device connects to one solar panel, offering granular control and monitoring at the individual module level. This is ideal for systems requiring detailed module-level performance tracking and enhanced safety isolation.
In contrast, the FR-PVMS-TT Series and FR-PVMS-TH Series use a 1-to-2 configuration, where one RSD device manages two solar panels, optimizing cost and component count while still delivering robust rapid shutdown and data monitoring capabilities.
