Tigo Energy tool spots powerline ‘crosstalk’ issues in both new and installed PV systems

After debuting its new Tigo Pure Signal technology, Tigo Energy has released a Solar PLC Signal Integrity Tool and expanded training material for commercial and industrial (C&I) solar installers and EPCs to resolve crosstalk issues in both new and existing systems.

Disturbances in PLC signals, often referred to as ‘crosstalk,’ can result in reduced effectiveness of system communications functions in large-scale photovoltaic (PV) systems. The design validation tool and companion training material will help installers preemptively identify potential PLC (powerline communications) signal integrity issues in large-scale C&I solar systems.

The updated TS4 Design and Installation Course now include best practices around mitigating PLC crosstalk issues at the design stage before they can cause disruptions in the field, the company says. The Solar PLC Signal Integrity Tool, in turn, can be used to quickly identify crosstalk risk in array plans or in systems already deployed.

The new tool was designed to be vendor-neutral and can provide guidance on how to resolve PLC rapid shutdown communications issues for solar systems with either Tigo or competitor solutions.

After the Solar PLC Signal Integrity Tool process is completed, installers receive an immediate assessment of the risk of PLC performance issues in the form of a score. The Tigo TS4 Design and Installation Course, integrated into the Tigo Academy, features a section on PLC rapid shutdown system design as well as a technical deep dive into the Tigo TS4 Flex MLPE product line.

All in, installers can learn how to best design, install and commission a Tigo TS4 system using any compatible solar inverter. The comprehensive two-hour course includes a certification exam worth 1.5 NABCEP continuing education credits.

“An important part of our mission at Tigo is to keep installers at the center of everything we do, and investing in tools and training is no small part of that,” said JD Dillon, chief marketing officer at Tigo Energy. “The resources we announced today represent the place at which the installer aspect of our mission intersects with our dedication to quality. As our partners in the field raise their stakes with ever larger installations, we are supporting them with things like this new PLC Tool, Pure Signal technology, and impactful continuing education to help them design and support the highest quality PV installations.”
