Tigo's RSS (Rapid Shutdown System) Transmitter completes the cost-effective rapid shutdown system architecture when paired with Tigo's UL-certified TS4-F (integrated) and/or TS4-R-F (retrofitted/add-on) solutions. 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 690.12 specifications utilizing power-line communication (PLC).
