Tigo TS4-A-2F Handles Rapid Shutdown for Two Modules
The Tigo TS4-A-2F is an add-on rapid shutdown device that serves two PV modules with one unit. The 25A version is rated 20A Imp / 25A Isc and 1400W (700W per input), and Tigo states it complies with NEC 2017, 2020 and 2023 690.12 when installed with the Tigo RSS Transmitter or an inverter with a built-in Tigo certified transmitter.
Half the devices on the roof means fewer parts to buy and fit.
Why You'll Love The Tigo TS4-A-2F
One unit, two modules. Two inputs cut the number of rapid shutdown devices on the array in half.
High current rating. 20A Imp / 25A Isc helps accommodate bifacial and high-current modules.
Automatic shutdown. The array enters rapid shutdown mode on AC grid loss, in under 30 seconds.
Tested widely. UL certified and tested with hundreds of top inverter models.
Your life, with the Tigo TS4-A-2F
Your installer spends less time under the panels and your system meets code without fuss. The array stays safe for anyone who needs to work on the roof, and you get back to enjoying lower power bills.
