Tigo unveils fast shutdown technology for large PV installations – pv magazine USA

[ad_1]

US-based Tigo Energy has developed a new device to help it shut down utility-scale solar plants more quickly. Pure Signal technology works with its own fast shutter transmitters.

The DC power optimization specialist said it designed the new product specifically for large, complex systems in the commercial and industrial solar segment.

“Designed to improve the quality of the power line connection (PLC) signal, the clean signal technology reduces the impact of electromagnetic interference in large solar systems,” explained the manufacturer. “Built with patented advanced fast-shutdown technology, Tigo RSS transmitters with clean signal technology paired with an industry-leading array of solar inverters, offer solar installers and EPCs a new level of design and installation flexibility, and lower balance of system (BOS) and labor costs.”

The device has a transmission input voltage of 12 V and a transmission input current of 1 A, with an average and maximum power consumption of 0.85 and 5.5 W, respectively. It measures It measures 38mm x 41.3mm x 90.9mm and has an IP68 enclosure.

According to Tigo Energy, it eliminates the risk of disturbances in the device Programmable logic controller (PLC) signals, the so-called “cross”, reduces the efficiency of system connections in large systems. The new product is certified by the US-based Underwriters Laboratories and is compatible with hundreds of inverter models.

“The new generation of RSS transmitters with Pure Signal Technology are compatible with the company’s TS4-AF and TS4-A-2F quick-close product family and can be easily integrated into new projects or integrated into existing installations,” Tigo Energy said.
