Tigo Energy of Flex module level power electronics fame, keeps rolling out announcements. The latest this week is the debut of two 25-Amp Tigo TS4 MLPE products supporting the latest high-power and high-current bifacial solar modules.

The Tigo TS4-A-F 25A and Tigo TS4-A-2F 25A rapid shutdown devices will work for solar modules rated up to 700W (and a maximum input voltage of 80V per module), including bifacial modules. Both products feature compatibility with Pure Signal technology in Tigo RSS Transmitters and pair with an industry-leading list of third-party solar inverters to deliver design and installation flexibility for solar installers and EPCs.

As solar module power ratings and demand for higher power density continue to rise, products like these will be essential for large-scale commercial and industrial solar installations. Tigo TS4 rapid shutdown products ensure that installers have the flexibility to deploy the industry’s highest wattage solar modules to offer their customers the most energy production per available rooftop space.

Two modules can connect to the TS4-A-2F 25A, which enables 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 install ever larger C&I systems, and we are pleased 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 solar technology leader, and the more powerful 25-Amp TS4 products are a direct result of that.”

Tigo TS4 products also reduce balance-of-system (BOS) and labor costs because of a 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 with inverters from major suppliers and Tigo Enhanced partners Chint Power Systems (CPS), Solectria, Sungrow, Canadian Solar, and Growatt.

The new 25-Amp Tigo TS4 rapid 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 leading manufacturers.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
