Module-level PV Rapid Shutdown for 2 modules

The TS4-A-2F (Fire Safety) is the advanced add-on rapid shutdown solution that brings smart module functionality to standard PV modules for higher reliability. Ensure safety by upgrading existing PV systems or by adding safety features to new installations. 

The TS4-A-2F complies with NEC 2017 & 2020 690.12 Rapid Shutdown specifications when installed with the Tigo RSS Transmitter or an inverter with built-in Tigo certified transmitter.


Simple, Fast Installation

Snap to standard PV module frame or remove clips for rack mounting

PLC Signaling

Rapid shutdown signaling over PV conductors

Automatic Shutdown

PV array enters rapid shutdown in the event of AC grid loss

PVRSS Certified

Tested and UL certified with hundreds of top inverter models
