Tigo Energy Inc., a Flex MLPE (module level power electronics) supplier, has launched two 25-amp 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 fast closing devices provide advanced first-responder safety functionality for solar modules rated up to 700 W, including bifacial modules. Both products are compatible with Tigo RSS Transmitters’ Pure Signal technology and will be paired with a list of third-party solar inverters to provide ease of design and installation for solar installers and EPCs.
As solar module power ratings and the need for higher power density continue to rise, the Tigo TS4-AF 25A and Tigo TS4-A-2F 25A are essential building blocks for large commercial and industrial solar installations. Tigo TS4 fast closing products ensure installers have the flexibility to deploy high wattage solar modules to offer their customers the most energy production per available roof space.
Tigo TS4 products also reduce balance-of-system (BOS) and labor costs due to the no-bolt 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 simple, plug-and-play pairing of inverters from major suppliers and Tigo Enhanced partners. Chint Power Systems (CPS), Solectria, Sungrow, Canadian Solar and Growatt.
In addition, the new 25-Amp Tigo TS4 devices offer plug-and-play support for all solar modules up to 700 W (one module for the TS4-AF 25A and two 700W modules for TS4-A-2F 25A) and is rated for a maximum short current of 25Amps and a maximum input voltage of 80V per module. They comply with NEC 2017 and 2020 690.12 Rapid Shutdown specifications when installed with a Tigo RSS Transmitter and UL PVRSS certified inverter or an inverter with a built-in Tigo-certified transmitter
reliable frame mounting that requires only 10 seconds for installation. The devices are industry-standard MC4 connectors with an IP68 enclosure rating for maximum durability as well as IEC and UL-certified for global acceptance. They reduce working time by connecting two TS4-A-2F 25A modules, enabling 16% fewer connections in a 14-panel string compared to single-channel MLPE.
“At Tigo, we serve a rapidly growing number of customers worldwide who are installing larger C&I systems, and we are pleased to serve that market with safe, reliable, and now more powerful products,” said Jing Tian, Tigo Kusog’s chief growth officer. “Our investments in innovation ensure that Tigo remains a leader in solar technology, and the more powerful 25-Amp TS4 products are a direct result of that.”
The new 25-Amp 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 from manufacturers .
