Tigo Energy TS4-A-F Module Add-On Rapid Shutdown Unit, Fire Safety, 458-00252-32

Note: Rapid shutdown activation of TS4-A-F requires RSS Transmitter

The TS4-A-F (Fire Safety) is the advanced add-on/retrofit 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-F complies with NEC 2017 690.12 Rapid Shutdown specifications when installed with the Tigo RSS Transmitter or an inverter with built-in Tigo certified transmitter.
