Description Tigo’s RSS (Rapid Shutdown System) Transmitter completes the cost-effective rapid shutdown system architecture when paired with Tigo’s UL-certified Fire Safety solutions – including the TS4-A-F (add-on), TS4-A-2F (add-on for two modules). The RSS Transmitter sends a signal to the TS4-F units to keep PV modules connected while powered on 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 2014, 2017, and 2020 690.12 rapid shutdown specifications utilizing power-line communication (PLC). Available as a Kit, DIN Rail, or PCBA for integration into inverters. Functions

• Rapid shutdown initiation device for Tigo TS4-A-F and TS4-A-2F
