Tigo Energy’s TS4-A-F rapid shutdown device (RSD) can now support solar modules up to 700-watts, the company says, trying to get ahead of the PV market’s anticipated future capacity increases. The Tigo TS4-A-F RSD continues to provide installers with a single product that works with a broad family of inverters and modules.

As solar module power ratings continue to rise, the Tigo TS4-A-F RSD had to adapt, as it serves all solar segments, from residential, C&I (commercial and industrial) and utility scale. Through the Tigo Enhanced program, Tigo customers and installers have the freedom to choose the right equipment for their solar projects through a simple plug-and-play model in combination with major inverter suppliers Chint Power Systems (CPS), Solectria, Sungrow, Canadian Solar, and Growatt. Additionally, the new Tigo TS4-A-F RSD offers:

  • plug-and-play support for all solar modules up to 700W, and is rated for a maximum current of 15 amps and a maximum voltage of 90 volts
  • compliance with NEC 2017 and 2020 690.12 Rapid Shutdown specifications when installed with the Tigo RSS Transmitter and PVRSS certified inverter or an inverter with built-in Tigo certified transmitter
  • reliable solutions matching other Tigo products, utilizing the same frame mounting features requiring only 10 seconds for installation
  • industry standard MC4 connectors with an IP68 enclosure rating for maximum durability

The Tigo TS4-A-F RSD ensures that installers have the flexibility to deploy the industry’s highest wattage solar modules and offer their customers the most energy production per available rooftop space.

In order to meet the rapid shutdown requirements which have propagated globally, Tigo products are UL PV Rapid Shutdown System (PVRSS) certified with hundreds of inverters. Reliable rapid shutdown functionality is essential to ensuring fire safety for system owners as well as firefighters and first responders who can now safely perform their work without encountering high-voltage DC electricity from solar components. In addition to fire safety, Tigo leads the way in solar innovation by enabling plug-and-play installation and rapid commissioning.

“Rapid shutdown is an essential element of PV systems safety, and the 700W Tigo TS4-A-F now supports new high-power modules,” said Jing Tian, Chief Growth Officer at Tigo Energy. “Our ability to maintain MLPE market leadership comes from a deep well of innovation and our commitments to give our customers the power to use exactly the components that satisfy their needs. We are very happy to extend this level of flexibility for PV safety to the highest power solar modules on the market today.”

The new high-power 700W Tigo TS4-A-F RSD will be available for purchase directly and from Tigo channel partners starting on June 22, 2021.
