Enphase Energy says it has shipped more than 8 million IQ microinverters and nearly 500 megawatt-hours (MWh) of IQ batteries from U.S. contract manufacturing facilities; the company began shipping microinverters from American plants in 2023.
The U.S.-made lineup includes the company’s gallium nitride (GaN)-based IQ9N microinverters for residential solar, along with IQ9N-3P and IQ9S-3P commercial microinverters for 480-volt three-phase projects.
Enphase also ships the IQ Battery 10C from U.S. facilities, giving installers and third-party ownership providers a domestically produced battery for solar-plus-storage projects. Products with a “DOM” suffix in the SKU are made with domestic content and may help eligible projects qualify for domestic content bonus tax credits.
Enphase directs customers to its website for information on which products may be compliant with foreign entity of concern (FEOC) rules and advises them to consult legal and tax advisors on eligibility.
“Eight million microinverters is enough to support hundreds of thousands of American homes and businesses,” said Ken Fong, senior vice president of sales at Enphase Energy, in a statement. “The same U.S. manufacturing base that builds our IQ9 Microinverters and IQ Batteries is now building power modules for AI data centers. That’s what American manufacturing at scale makes possible.”
Enphase is also extending its U.S. manufacturing into AI data center power. The company has started building power modules for its IQ Solid-State Transformer in Arlington, Texas, and is using them to assemble and validate full-scale racks.
