Apex Power Conversion, a solar and storage company, recently celebrated the opening of its U.S. headquarters and manufacturing facility in Mesa, in conjunction with the American Clean Power Association’s Cleanpower 2025 Expo in Phoenix.

Apex Power — in Pursuit Park within the Elliot Road Technology Corridor — will initially employ up to 300 people, with plans to employ up to 700 by 2029, according to a release.

Representing an over $60 million investment, the 206,000-square-foot facility is used for customer engagement and product training, and will be expanded for advanced multi-megawatt power conversion manufacturing for integrating renewables and energy storage with the grid. The first full units are expected to be manufactured in the first quarter of 2026.

“At Apex Power, we are relentless in pursuing our mission to develop and manufacture the most advanced power conversion systems technologies that directly enable the integration of renewable energy and storage onto our power grids,” Jacob Marshall, president and co-founder of Apex Power Conversion, said in the release. “It is a humbling honor to launch Apex Power’s headquarters and manufacturing operations in my family’s hometown of Mesa. Apex’s culture is grounded in our purpose and our partnerships, and we look forward to showing the world exactly what we are capable of.”

Apex Power is to support the state’s power grid expansion and clean energy demand with its manufacturing of advanced inverter systems, the release states.

“This investment not only brings quality jobs and innovation to our community, it also strengthens Mesa’s reputation as a destination for global companies and forward-thinking industries,” Mesa Mayor Mark Freeman said in the release. “We’re excited to welcome Apex Power and look forward to the positive impact they’ll have on our economy, workforce and future.”

“Apex Power’s decision to locate in southeast Mesa reinforces our position as a hub for energy innovation and advanced manufacturing,” said Mesa Vice Mayor Scott Somers. “This investment means high-quality jobs, cutting-edge technology and a stronger, more resilient energy future for our region. We are proud to welcome Apex Power to the Mesa business community.”
