Tigo Energy Enters Licensing Agreement with QC Solar to Expand Rapid Shutdown Technology

Solar industry’s leading Flex MLPE supplier Tigo Energy announced a commercial technology licensing agreement with QC Solar, a Suzhou-based manufacturer of solar PV connectors and PV module junction box products.

The licensing agreement allows QC Solar to use Tigo RSS technology in its products and leverage its compatibility with other Tigo components.

Tigo RSS technology will be integrated with QC Solar’s Smart Junction Box, which will provide core safety mechanisms to solar modules to minimize hazards to solar installers and first responders.

QC Solar customers who deploy its new Smart Junction Box will be able to deploy the Tigo RSS Transmitter in accordance 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, QC Solar. “We look forward to commercial production and marketing of our Rapid Shutdown Smart Junction Box with the Tigo technology we are licensing. This is an important step forward to protecting photovoltaic power plants worldwide.”

Tigo's rapid shutdown technology enables system owners, firefighters, and first responders to work without encountering high-voltage DC electricity from solar components.

The need for safe photovoltaic solar is revognized globally, with rapid shutdown specifications like those pioneered in the U.S. recently 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, 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.”
