Tigo RSS Transmitter for Tigo RSD Modules, Single and Dual Core Options, Transmitter for Shutting Down Solar Production

Tigo’s RSS Transmitter, a rapid shutdown device, is a companion product to the Tigo TS4-A-F and TS4-A-2F, and it provides the signal to shut down solar production. This is important for fire safety. The Transmitter has built-in Pure Signal technology to align multiple RSS Transmitters to communicate together over multiple solar arrays.

Each set of series-connected panels creates a single string, and Tigo has no limit to how many panels can be on a single string. One core, the sensor that sends the shutdown signal, handles up to 10 strings (either all positive wires or all negative wires) and must be installed within 1,000ft of the TS4 module. Distances greater than 1,000ft require a second core as the PLC (powerline communication) signal gets weaker over longer distances. 

The RSS Transmitter offers both one and two core variations. Cores cannot be purchased separately, so it’s important to consider both current and future solar needs before purchase.

In larger systems, link up to 10 transmitters for a synchronized “keep-alive” signal across multiple arrays. This is perfect for systems with more than 10 arrays going to the same inverter or with arrays going to different inverters. 

TS4-A-F and TS4-A-2F modules can work with a handful of RSS signals utilizing PLC, but Tigo strongly recommends using Tigo branded or approved RSS transmitters to ensure the modules will shut down when needed and maintain “keep-alive” signals during normal operation.
