Tigo Single Core 100 Amp RSS DIN Rail Transmitter Kit | Includes Power Supply & Outdoor Enclosure

Give every rooftop solar installation the NEC-compliant rapid-shutdown protection today’s codes demand—without sacrificing power production.

Why Install the Tigo RSS Transmitter Kit?

• Full NEC 2014/2017/2020 Compliance
  Meets 690.12 rapid-shutdown requirements in 36+ U.S. states when paired with Tigo TS4-A-F or TS4-A-2F units and a UL-listed PVRSS inverter.

• Instant, Code-Required Safety
  At the flip of a switch, firefighters and first responders can drop array voltage to a safe level—protecting lives, property, and your investment.

• Proven PLC Signaling
  Power-line communication keeps every TS4-F on the string fully energized during normal operation and puts modules into rapid-shutdown mode the moment grid power is lost or the transmitter is switched off.

• Outdoor-Ready Durability
  IP68 / NEMA 4 enclosure, -20 °C to 50 °C operating range, and a 10-year Tigo warranty ensure reliable performance in harsh climates.
