Module-level power electronics (MLPE) supplier Tigo Energy signed a commercial technology licensing agreement with QC Solar, a manufacturer of solar PV connectors and PV module junction box products headquartered in Suzhou, China. The licensing agreement enables QC Solar to use Tigo RSS technology in its products and leverage its compatibility with other Tigo components.

QC Solar will integrate Tigo RSS technology with its Smart Junction Box. Customers of QC Solar who deploy its new Smart Junction Box will, in turn, be able to deploy the Tigo RSS Transmitter in compliance with rapid shutdown regulations and requirements.

“With module-level rapid shutdown technology from Tigo, we will ensure that our customers’ solar systems automatically reduce system voltage during critical events such as structure fires so that firefighters can confidently perform their work,” said Zhenggang Duan, General Manager at QC Solar. “We look forward to commercial production and marketing of our Rapid Shutdown Smart Junction Box with the Tigo technology we are licensing.”

Tigo rapid shutdown technology reduces high-voltage DC electricity from solar components in emergency situations. Rapid shutdown was initially pioneered in the U.S. but has recently been adopted in the Philippines, Thailand, and Singapore, and numerous other countries actively evaluating similar regulations.

“This technology licensing agreement with QC Solar represents another indicator of the strength of the Tigo IP portfolio,” said Zvi Alon, chairman and CEO at Tigo Energy. “We are pleased to welcome QC Solar into the community of companies leveraging our rapid shutdown to make solar safe and look forward to serving our customers with technology products that offer broad compatibility with Tigo innovations.”
