Tigo and EG4 to host Q&A at RE+ 2025 to discuss how Texas-based manufacturing will strengthen product availability and reliability for U.S. installers.

The manufacturing partnership between Tigo and EG4 will build momentum to help bring critical energy manufacturing back to the United States and power reliable, homegrown solar solutions. In March 2025, EG4 Electronics' parent company, Energy Access Innovations (EAI), announced the acquisition of a state-of-the-art 310,000 sq. ft. manufacturing facility in Commerce, Texas. The facility is a further milestone for American energy independence and economic prosperity, creating more than 1,000 new American jobs and helping to advance the nation's energy security.

"We believe in energy autonomy for our customers just as much as we believe in manufacturing autonomy for American innovators, and this partnership with Tigo allows us to make significant progress on both of those fronts," said James Showalter, founder at EG4 Electronics. "This partnership with Tigo is exactly the kind of arrangement we had in mind when we announced our new manufacturing facility earlier this year. We look forward to building American-made energy infrastructure together with Tigo."

"EG4 is at the forefront of re-shoring manufacturing for American solar innovations, and we are delighted to work in partnership with James and his team," said Zvi Alon, chairman and CEO at Tigo Energy. "Tigo and EG4 are in alignment on some of the most critical success factors in solar, which include innovation and quality. This makes for a strong foundation for success, and I expect great things for American energy independence from this important collaboration."
