Product Overview:

The Tigo Rapid Shutdown System (RSS) Transmitter is a crucial component for enhancing the safety of your solar energy system. By utilizing Power Line Communication (PLC), the transmitter sends a continuous keep-alive signal to Tigo's TS4-A-F and TS4-A-2F units, allowing the PV modules to operate normally. In the event of an emergency or when the system needs to be powered down, turning off the RSS Transmitter ceases the signal, prompting the TS4 units to rapidly reduce the module voltage to safe levels.

This transmitter is equipped with Tigo's Pure Signal technology, which is particularly beneficial in large or complex installations where multiple transmitters are required. Pure Signal technology synchronizes multiple RSS Transmitters, minimizing crosstalk and signal interference, thereby ensuring reliable communication and operation across the entire PV system.

Installation and Compatibility:

Designed for straightforward installation, the Tigo RSS Transmitter does not require a commissioning process, making it an ideal choice for both new installations and retrofits. Its compatibility with a wide array of UL-listed inverters enhances its versatility, allowing it to be integrated into various system designs without compatibility concerns.

Safety and Compliance:

Safety is paramount in PV system design, and the Tigo RSS Transmitter ensures compliance with NEC 690.12 rapid shutdown requirements. By enabling module-level deactivation, it provides an added layer of protection for first responders and maintenance personnel, reducing the risk of electrical hazards during emergencies or servicing.
