Product Description

A PVRSS (Photovoltaic Rapid Shutdown System) provides a means for firefighters and first responders to stop or reduce the voltage from the PV array, so they can stay as safe as possible from electrical hazards while still doing their jobs efficiently. Rapid shutdown is a requirement as part of the U.S. National Electric Code. The majority of US states (36 and growing as of 2021) have adopted NEC 2017 or NEC 2020, which require new rooftop PV systems to have module level shutdown capability. Tigo’s TS4-A-O, TS4-A-S, TS4-A-F, and TS4-A-2F products all meet rapid shutdown compliance when paired with a UL PVRSS certified inverter.

The Tigo Rapid Shutdown System (RSS) Transmitter is part of a rapid shutdown solution when paired with Tigo TS4-F (Fire Safety), a PV module rapid shutdown unit. While powered on, the RSS Transmitter sends a signal to the TS4-F units to keep their PV modules connected 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 690.12 specifications for 2014, 2017, and 2020 and uses PLC signaling for rapid shutdown. The RSS Transmitter Outdoor Kit includes an RSS Transmitter, outdoor enclosure, 120/240VAC power supply, and one or two RSS Cores.
