Tigo Energy Brings New Solar Rapid Shutdown Technology to Market

Tigo Energy Inc. is a Flex MLPE (module-level power electronics) supplier. It has launched Pure Signal technology for Tigo RSS Transmitters. Pure Signal technology is designed to reduce electromagnetic interference in large-scale solar system. Tigo RSS Transmitters with Pure Signal technology are based on patented, advanced rapid shutdown technology. They can be used in conjunction with a variety of third-party solar Inverters to provide new design and installation flexibility for solar contractors and EPCs. This will allow them to significantly reduce balance of system (BOS), and labor costs.

The Tigo RSS Transmitter using Pure Signal technology was designed to serve Tigo customers that deploy increasingly large and complex systems in order to reach the industrial and commercial solar markets. Disturbances in PLC signals, often referred to as ‘crosstalk,’ can result in reduced effectiveness of system communications functions in large-scale systems. PLC signal disruption is no longer a concern with Tigo Pure Signal technology. Cable runs from adjacent inverters or circuits are no longer at risk with Tigo Pure Signal technology.

“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,” says 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.”

Tigo RSS Transmitters equipped with Pure Signal technology have been UL PVRSS-certified and come with hundreds of inverter models. The new generation of RSS Transmitters with Pure Signal technology are compatible with the company’s TS4-A-F and TS4-A-2F rapid shutdown product family and can be easily integrated into new projects or retrofitted into existing installations.

“Our mission is to provide high-quality, reliable, and flexible MLPE solutions to meet customers’ needs for different system configurations. Pure Signal technology delivers on that mission,” comments Jing Tian, chief growth officer at Tigo Energy. “With Pure Signal technology we open a new universe of solar installation design possibilities and provide cost savings in BOS and labor.”
