Enphase Energy said it has shipped more than 8 million IQ Microinverters and nearly 500 MWh of IQ Batteries from US contract manufacturing facilities. The company is also assembling solid-state transformer power modules in Arlington, Texas.
Why it matters
The milestones show domestic production scaling for solar hardware at a time when US sales are declining. Enphase's expansion into full rack assembly in Texas signals a push to build more of its product lineup inside the United States.
Enphase shipped about 4.23 million microinverters from US sites between July 2025 and March 2026, and US sell-through fell 35% year on year in the third quarter. Global third-quarter shipments were roughly 1.42 million microinverters and 129.9 MWh of batteries.
The players
Enphase Energy
Enphase Energy is a California-based solar microinverter and battery maker whose products are widely installed on residential rooftops.
The details
Enphase said its US-made products are built through contract manufacturers, with its website listing Flex in South Carolina and Salcomp in Texas as partners. The company is using its new solid-state transformer modules in Arlington to assemble and validate full-scale racks, with complete rack assembly planned in Texas.
Timeline
May 2025: Enphase reported 50 MWh of US-shipped batteries and 6.5 million microinverters.
July 2025 through March 2026: About 4.23 million microinverters shipped from US sites.
November 9, 2026: Enphase announced the US shipment milestones.
Manufacturing Shift
Enphase's US output sits alongside the advanced manufacturing production tax credits, which the company sold in 2025 at 93% of face value for $235.0 million. The shipments show those incentives translating into domestic production volume even as US sell-through fell 35% in the third quarter.
Homeowners and installers buying Enphase microinverters and batteries may see products built with domestic content, which the company marks with a DOM suffix on certain SKUs. The shift toward US assembly does not change the products' specifications, which are set by the company's product lineup.
The takeaway
Domestic production of solar hardware is scaling, but US demand has softened, so manufacturing volume and market demand are moving in different directions. Watch whether the rack assembly planned in Texas expands the list of US-built products.
