Enphase Says Over 8 Million Microinverters Have Shipped From US Sites

• Enphase said it has shipped more than 8 million IQ Microinverters and nearly 500 MWh of IQ Batteries from US contract manufacturing facilities.
• US-shipped battery volume is up about tenfold from the 50 MWh Enphase reported in May 2025.
• Enphase has started building solid-state transformer power modules in Arlington, Texas, and plans to assemble full racks in the state.

Enphase Energy said on Nov. 9 that it has shipped more than 8 million IQ microinverters and nearly 500 MWh of IQ Batteries from US contract manufacturing facilities, with microinverter shipments dating back to 2023.

The US lineup now includes the gallium nitride-based IQ9N for homes and the IQ9N-3P and IQ9S-3P for 480-V three-phase commercial projects, the company said in a statement. The IQ Battery 10C also ships from US sites. SKUs with a "DOM" suffix are made with domestic content, and Enphase says they may help eligible projects qualify for domestic content bonus tax credits.

The release names no contract manufacturers and only one location, Arlington, Texas. Enphase's website lists contract partners Flex in South Carolina and Salcomp in Texas.

The US shipments in numbers

• 8 million-plus IQ Microinverters shipped from US contract facilities since 2023.
• 500 MWh, or just under, of IQ Batteries shipped from US facilities, about 10 times the 50 MWh reported in May 2025 (list.solar calculation).
• 8.8% or more of the approximately 90.8 million microinverters Enphase has shipped worldwide (list.solar calculation).
• 4.23 million microinverters shipped from US sites from July 2025 through March 2026, summing three quarterly reports (list.solar calculation).
• $235.0 million of 2025 advanced manufacturing tax credits sold at 93% of face value, according to Enphase's third-quarter results.
• 5.5 kW per transformer power module, with racks of up to 5 MW designed to convert medium-voltage AC to 800 VDC.

Enphase's quarterly results point to a higher total. They show about 4.23 million microinverters shipped from US sites in the three quarters from July 2025 through March 2026. Added to the 6.5 million announced in May 2025, that would put the total above 10.7 million (list.solar calculation). The new release does not say how its figure was counted.

US sell-through fell 35% year on year in the third quarter. Global shipments that quarter were approximately 1.42 million microinverters and 129.9 MWh of batteries.

Work in Arlington covers power modules for the IQ Solid-State Transformer, aimed at AI data centers. "Eight million microinverters is enough to support hundreds of thousands of American homes and businesses," Ken Fong, Enphase's senior vice president of sales, said in the statement.

Enphase is using the modules to assemble and validate full-scale racks, and it plans to assemble complete racks in Texas. It gave no date.
