Tigo RSS Transmitter Powers Code Compliant Rapid Shutdown
The Tigo RSS Transmitter is the rapid shutdown activator for Tigo fire safety MLPE such as the TS4-A-F and TS4-A-2F. It sends a keep-alive signal over the PV conductors using power-line communications (PLC) through single or dual cores, and each core encircles up to 10 PV string conductors.
Tigo's Pure Signal technology syncs one coordinated keep-alive signal across multiple transmitters to mitigate crosstalk.
Why You'll Love The Tigo RSS Transmitter
Meets the code. Tigo lists NEC 690.12 2017, 2020 and 2023 compliance, with automatic or manual shutdown.
Scales with you. From residential to large utility projects, with up to 10 synced transmitters in a series.
Fewer mistakes. The bi-colored core keeps conductor polarity consistent during installation.
Inverter flexibility. Tigo states it is compatible with most inverters on the market.
Your life, with the Tigo RSS Transmitter
Flip off the AC and your array drops to safe levels on its own. Your installer has a clean DIN rail install, your inspector has the documentation, and you have peace of mind.
