Rooftop solar panels with small power electronics units mounted underneath and an inverter

Solar electronics company Tigo Energy announced on August 25, 2025, a manufacturing and marketing partnership with EG4 Electronics to produce Tigo’s optimized inverters and module-level power electronics (MLPE), along with EG4 inverters, in the USA.

The partnership

Installers in the USA already pair EG4 inverters with Tigo devices, which are certified as compatible. In March 2025, EG4’s parent company, Energy Access Innovations, announced it had acquired a 310,000-square-foot manufacturing plant in Commerce, Texas. The companies said that facility would create more than 1,000 jobs.

“This partnership with Tigo is exactly the kind of arrangement we had in mind when we announced our new manufacturing facility earlier this year.”

James Showalter, founder, EG4 Electronics

Tigo chairman and CEO Zvi Alon said EG4 is “at the forefront of re-shoring manufacturing for American solar innovations.” The companies planned a joint session for installers at the RE+ 2025 trade show in Las Vegas.

Why it matters for Made in USA

Solar electronics have mostly been made in Asia. Federal incentives that reward domestic content have pushed solar companies to look for USA production, and partnerships like this one are a faster path than building new plants alone.

Buyers should read the claims closely. Domestic content rules for tax credits and the FTC’s Made in USA standard are different tests. A product assembled in Texas may count toward a domestic content calculation and still not qualify for an unqualified Made in USA label if key components like chips and circuit boards are imported.
