Tigo Energy teams with EG4 Electronics to manufacture inverters and MLPE in Texas
Partnership ties Tigo’s optimized inverters to EG4’s 310,000 sq. ft. Commerce facility
A new 310,000-square-foot manufacturing plant in Commerce, Texas, will soon be pumping out both Tigo Energy and EG4 Electronics solar power hardware. The two inverter brands formalized a partnership this week to co-produce Tigo’s optimized inverters and module level power electronics (MLPE) alongside EG4’s inverter products at the facility.
The combo facility formalizes what’s already happening in the field: EG4 inverters are often paired with Tigo MLPE devices, which are certified as compatible. Now, both product lines will roll off the same U.S. production line.
The two companies plan to highlight the partnership at the RE+ tradeshow in Las Vegas (Sept. 9–12, 2025), hosting a joint Q&A session for solar installers.
Manufacturing context
EG4’s parent company, Energy Access Innovations (EAI), acquired the Texas facility in March 2025. The site is expected to create more than 1,000 American jobs while anchoring part of the nation’s re-shoring push for energy hardware.
“We believe in energy autonomy for our customers just as much as we believe in manufacturing autonomy for American innovators,” said James Showalter, founder of EG4 Electronics. “This partnership with Tigo allows us to make significant progress on both of those fronts.”
Even though it has its own inverter, Tigo is most known for its MLPE and rapid shutdown solutions, which can be paired with other solar inverters. By aligning its inverter production with EG4’s U.S. manufacturing hub, Tigo gains a path toward higher domestic content.
“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. “I expect great things for American energy independence from this important collaboration.”
