Simple Module-Level Rapid Shutdown
The Tigo TS4-A-F communicates with the Tigo RSS Transmitter using a PLC “keep-alive” signal. When that signal is removed, the TS4 units enter rapid shutdown mode, helping reduce DC voltage on the rooftop during emergencies or system shutdown.
For compatible inverters with an integrated RSS Transmitter, installation can be simplified without requiring a separate external transmitter.
Ideal for rooftop solar installations requiring a dependable, code-compliant rapid shutdown solution with broad inverter compatibility.
