Tigo Energy releases rapid shutdown devices for up to 700-W panels

Tigo Energy has announced the launch of two 25-A Tigo TS4 MLPE products that support the latest high-power and high-current bifacial solar modules. The Tigo TS4-AF 25A and Tigo TS4-A-2F 25A quick shutdown devices provide advanced first-responder safety functionality for solar panels up to 700W, including bifacial modules. Both products are compatible with Pure Signal technology in Tigo RSS transmitters and are linked to a list of third-party solar inverters to provide design and installation flexibility for solar installers and EPCs.

As the power of solar modules and the demand for higher power density continue to rise, the Tigo TS4-AF 25A and Tigo TS4-A-2F 25A are essential building blocks for large-scale commercial and industrial solar installations. Tigo TS4 quick shutdown products give installers the flexibility to deploy the industry’s highest wattage solar modules to provide their customers with the most energy production per available roof space. Tigo TS4 products also reduce balance-of-system (BOS) and labor costs due to a boltless design and no need for additional ground wiring. Through the Tigo Enhanced program, Tigo customers and installers have the freedom to choose the right equipment for their solar projects through easy plug-and-play pairing with inverters from major vendors and Tigo Enhanced partners Chint Power Systems (CPS ), Solectria, Sungrow, Canadian Solar and Growatt.

In addition, the new 25-A Tigo TS4 devices offer:

  • Plug and play support for all solar modules up to 700 W (one module for TS4-AF 25A and two 700 W modules for TS4-A-2F 25A) and suitable for a maximum short-term current of 25 A and a maximum input voltage of 80 V per module
  • Compliance with NEC 2017 and 2020 690.12 Rapid Shutdown Specifications when installed with the Tigo RSS Transmitter and UL PVRSS Certified Transmitter or an inverter with a built-in Tigo Certified Transmitter
  • Reliable frame mounting that only takes 10 seconds to install
  • Industry standard MC4 connectors with an IP68 housing rating for maximum durability
  • IEC and UL certified for worldwide acceptance
  • Reduced labor time by connecting two modules on the TS4-A-2F 25A, allowing 16% fewer connections on a 14-panel string compared to single channel MLPE

“At Tigo, we serve a rapidly growing number of customers worldwide who are installing increasingly larger C&I systems, and we are excited to serve that market with safe, reliable and now even more powerful products,” said Jing Tian, ​​chief growth officer at Tigo . Energy. “Our investments in innovation ensure that Tigo remains a leader in solar, and the more powerful 25-Amp TS4 products are a direct result of that.”

The new 25-A Tigo TS4 fast shutdown products are fully compatible with Tigo RSS transmitters (with or without Pure Signal technology) and are UL PVRSS certified with hundreds of inverter models.
