Tigo's new RSS (Rapid Shutdown System) Transmitter completes its cost-effective rapid shutdown system architecture when paired with TS4-F (Fire Safety). Tigo's RSS Transmitter accompanies the UL-certified TS4-F (integrated) and TS4-R-F (retrofitted/add-on) solutions. The RSS Transmitter sends a signal to the TS4-F units to keep their 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 U.S. National Electric Code (NEC) article 690.12 specifications for 2014 and 2017 and supports the SunSpec-defined signaling for rapid shutdown with power-line communication (PLC). The TS4-F units and RSS Transmitter require no commissioning process.
