Tigo TS4-A-F 700W Module-Level Rapid Shutdown Device
The Tigo TS4-A-F (Fire Safety) is the module-level rapid shutdown device for PV modules up to 700W. It clips to the module frame or the racking and, when the grid is lost or shutdown is triggered, brings string voltage down to safe levels in under 30 seconds: extra protection for firefighters and maintenance staff.
The command travels over the PV conductors as a PLC signal: it needs the Tigo RSS transmitter or an inverter with a built-in certified Tigo transmitter. It suits both new and existing systems, with 99.9%% peak efficiency and a 25-year warranty.
