Tigo Releases New Rapid Shutdown Transmitter for Integrated NEC 2017 Compliance

Tigo’s new UL-certified RSS Transmitter compliments the TS4-F (Fire Safety) for the most cost-effective residential and commercial Rapid Shutdown solution

Tigo®, pioneer of the smart modular Flex MLPE platform, today announced its new RSS (Rapid Shutdown System) Transmitter to complete its cost-effective rapid shutdown system architecture when paired with TS4-F (Fire Safety). Tigo's RSS Transmitter accompanies the UL-certified TS4-F (integrated) and TS4-R-F (retrofitted/add-on) solutions. Tigo is currently taking orders - contact sales@tigoenergy.com for more information. Consult your preferred PV supplier for the TS4-F integrated solution. To learn more, join Tigo's live RSS Webinar on November 14th at 10am PT.


The RSS Transmitter sends a signal to the TS4-F units to keep their PV modules connected while powered on and supplying energy. TS4-F units automatically enter rapid shutdown mode when the RSS Transmitter is switched off and resume energy production when power is restored to the RSS Transmitter. This solution complies with U.S. National Electric Code (NEC) article 690.12 specifications for 2014 and 2017 and supports the SunSpec-defined signaling for rapid shutdown with power-line communication (PLC). The TS4-F units and RSS Transmitter require no commissioning process.

Highlights of the RSS Transmitter include:

Meets NEC 2017 690.12 requirements
Module-level deactivation with TS4-F and TS4-R-F
Automatic or manual shutdown with TS4-F and TS4-R-F
Supports SunSpec signaling
UL-certified
Easy installation
No required commissioning process
Compatible & certified with many residential & commercial inverters from multiple suppliers
Available for integrated and retrofitted/add-on PV installations
"Providing a UL-certified transmitter to complete our second TS4 System Architecture solution for rapid shutdown has been Tigo's largest contribution to safer solar," says Zvi Alon, CEO at Tigo. "Tigo's RSS Transmitter is the only SunSpec keep-alive device for rapid shutdown with PLC in the solar market today. We are excited to be shipping and certifying with a large number of tier one inverter manufacturing partners by the end of the year."

Tigo and its many partners contributed expertise to solar standards with SunSpec Alliance. SMA, Fronius, ABB, Chint, HiQ Solar, Ingeteam, Kaco, Sungrow, and Yaskawa Solectria and others are among UL-listed PV inverter manufacturers that will be compatible with Tigo's RSS solutions. Tigo continues to expand its compliant inverter portfolio with many partner brands for its customers.

Tigo is currently taking orders for the RSS Transmitter - available as a Kit, DIN Rail, or PCBA.

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
