FR-PVMS-TH Series Comparison
Rapid Shutdown Technical Specifications and Features Overview
FR-PVMS-THQx is an excellent choice for cost-sensitive, space-saving deployments that still demand high safety and intelligence. Compared to THCx series, THQx models also offer rapid address configuration, new-generation module-level arc fault detection and AFCI arc protection.
Main Features
- Detects series and parallel arc faults quickly extinguish arcs and effectively prevent fires.
- Triggered when Smart Logger loses power or manually shuts down, to ensure maintenance and fire safety.
- Including voltage, power, power generation, temperature, and other snap data.
- 1600m long communication distance.
- Designs for two modules, highly cost effective.
- Real-time fault information on abnormality.

Rapid Shutdown Device Wiring Diagram
Fonrich Smart Safety Protector (RSD)
When installing a PV string with an odd number of PV modules, please refer to second row of diagram and only connect one PV module to relevant Smart Safety Protector.
Ensure that PV cables between PV module and inverter are protected by an additional protective cable tray.
Important Notes:
Fonrich does not provide emergency stop switch and temperature sensor. Not standard parts (i.e., emergency controller) by Fonrich, contact us in advance if needed.
