Tigo seeks to eliminate PLC crosstalk in C&I rapid shutdown with Pure Signal tech

Tigo Pure Signal

Disturbances in powerline communication (PLC) signals, often referred to as ‘crosstalk,’ can result in reduced effectiveness of system communications functions in large-scale systems. Tigo Energy is tackling the issue of PLC signal quality with the launch of Pure Signal technology for its RSS Transmitters.

The Tigo RSS Transmitter with Pure Signal technology is designed for installers deploying increasingly large and complex systems for the commercial and industrial (C&I) solar markets and will reduce the impact of electromagnetic interference in large-scale solar systems.

Tigo RSS Transmitters with Pure Signal technology are built on its patented rapid shutdown tech and are UL PVRSS certified with hundreds of inverter models from leading manufacturers. With Tigo Pure Signal technology, cable runs from different circuits or adjacent inverters will no longer risk PLC signal disruption.

“The Pure Signal technology helped us avert a significant amount of rework after a design review showed that some of our cable runs could be at risk of crosstalk issues,” said Mike Ulanski, director of construction at Catalyze. “Without the ability to put the new Tigo RSS Transmitter into play quickly, the timeline and profitability of the project would have taken a hit. The installation guidelines and design review from Tigo have been extraordinarily helpful, but this Pure Signal technology gives us much more flexibility at both design and install phases.”

The new generation of RSS Transmitters with Pure Signal technology can be easily integrated into new projects or retrofitted into existing installations.

“With Pure Signal technology we open a new universe of solar installation design possibilities and provide cost savings in BOS and labor,” said Jing Tian, chief growth officer at Tigo Energy. “I am delighted to see companies like Catalyze engaging to take full advantage of the solution.”

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've discusses 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.

We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
