The Tigo Rapid Shutdown System (RSS) Transmitter is part of a rapid shutdown solution when paired with Tigo TS4-F (Fire Safety), a PV module rapid shutdown unit. While powered on, the RSS Transmitter sends a signal to the TS4-F units to keep their PV modules connected 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 NEC 690.12 specifications for 2014, 2017, and 2020 and uses PLC signaling for rapid shutdown. The RSS Transmitter Outdoor Kit includes an RSS Transmitter, outdoor enclosure, 120/240VAC power supply, and one or two RSS Cores.

Module temperature sensor:

In general, this sensor measures the temperature on surfaces. By mounting the sensor on the back of the PV module, the module temperature can be measured.

The temperature of the PV module is one of the decisive factors for the power output. By supervision, the PV-owner can conclude the performance of the power chart.

Mounting tip: It is recommended to fix the sensor and the cable with an additional adhesive tape.
