A just-issued national security ban appears to exclude existing inverters for solar and battery projects — but future models could face restrictions, experts say.
Citing national security concerns, the Trump administration has banned the import and domestic use of new power inverters made outside the United States. The move could throw sand in the gears of gigawatts’ worth of planned solar, wind, and battery installations — projects that make up the vast majority of new electricity being built in the country.
On Tuesday, the Federal Communications Commission announced it had updated its “Covered List” to include “connected power inverters produced in foreign countries.” The list includes equipment and services considered to pose a threat to national security, meaning that these inverters “are generally prohibited from receiving FCC authorization to be imported, marketed, or sold in the U.S.,” the agency stated.
However, the ban currently applies only to future new models of inverters, not those already available in the market or being installed today — a distinction that could limit the immediate impact on the clean energy industry.
The FCC stated that its action was prompted by a “White House-convened Executive Branch interagency body with appropriate national security expertise,” which determined that foreign-made inverters, “regardless of the nationality of origin, “‘pose unacceptable risks to the national security of the United States or the safety and security of United States persons.’”
Inverters — devices that convert direct current electricity into alternating current suitable for transmission over power grids — are an irreplaceable component of utility-scale solar, battery, and wind power projects, home solar and battery systems, electric vehicles chargers, heat pumps, and other electricity systems.
The vast majority of inverters in use today are connected to communications networks, which puts them under FCC regulatory purview. And most inverters used in large-scale solar projects are built outside the U.S. — many of them in China, which has been the primary target of national security concerns.
The FCC’s new restrictions do come with that important caveat, though: They only “apply to new device models.” That qualification appears to exclude foreign inverter models that have previously won FCC approval.
The FCC also specified that the new restriction “does not impact a consumer’s continued use of devices they previously acquired,” or “prevent retailers from continuing to sell, import, or market relevant models approved previously through the FCC’s equipment authorization process.”
Those two statements have tempered some of the more drastic interpretations of the potential impact of the FCC’s announcement among energy industry market participants.
“In our world, investors are currently seeing this as kind of a non-event” due to this interpretation, John Miller, a managing director and energy transition policy analyst at investment bank TD Cowen, told Canary Media in a Wednesday morning email. “If either of those conditions were to change, this becomes a much bigger issue.”
This point was echoed by Julien Dumoulin-Smith, head of equity research for power, utilities, and clean energy at investment firm Jefferies, in a Wednesday morning statement. “[T]his has a minimal impact today. There seems latitude to continue to purchase existing inverter models on the market,” he wrote.
On the other hand, Dumoulin-Smith pointed out that any Trump administration steps to restrict new models of foreign-made inverters could create a “long, gradual shift in market share.”
Threats of the Trump administration targeting foreign inverters were first reported in late June by Reuters, which cited unnamed sources stating that a ban on Chinese-made inverters was in the works.
Last year, Reuters reported that technology experts investigating Chinese inverters had discovered communications devices that could be a security risk, citing anonymous sources. Later in 2025, Republicans in the House of Representatives wrote a letter to Commerce Secretary Howard Lutnick asking him to use the Commerce Department’s authority to “block future imports of Chinese equipment used in critical infrastructure nationwide.”
Chinese companies such as Sungrow and Chint Power Systems provide the majority of inverters for utility-scale clean energy and battery projects in the U.S., while U.S.-based Enphase Energy and Israel-based SolarEdge provide the majority of inverters for residential rooftop solar systems.
The FCC’s update targets any new inverters not made in the U.S., including those that U.S.-based companies produce in other countries. That could encompass inverters from other major providers to the solar market, such as Germany-based SMA Solar Technology and Austria-based Fronius International, as tracked by clean energy consultancy Wood Mackenzie.
If the FCC’s ban were to be expanded to include inverters currently being manufactured and sold for use in the U.S., the impact could be drastic. The U.S. built 50 gigawatts of new wind, solar, and battery capacity in 2025, more than any year prior, making up roughly 92% of new generating capacity. And the U.S. Energy Information Administration forecasts these trends will continue in 2026, with solar set to provide 51% of the new utility-scale electricity capacity, batteries 28%, and wind 14%.
In the immediate future, projects likely won’t have to abandon the inverters they’ve already purchased or plan to install, said Joe Shangraw, a solar research analyst at Wood Mackenzie. But he also cautioned that, as with any other industry, “eventually, currently approved products will become obsolete.”
That means inverter manufacturers will ultimately have to bring new products to market and submit them for FCC approval, at which time they’ll have to contend with the agency’s new rules. At that point, any inverters made outside the U.S. will be barred from sale and use unless they undergo a distinct conditional approval or waiver process, he said.
Shangraw also noted that the need to bring new products to the market could be accelerated if the federal government sets new requirements on cybersecurity, grid functionality, or other inverter capabilities.
“If that would require a significant hardware or software update, that would be something where you’d have to request some permissive change from the FCC, or ask for a totally new FCC ID” designating a new model of device for the agency’s review, he said. “So it’s certainly relevant and impactful — probably not in the next couple of months but in the next year or so.”
This growing uncertainty over the federal government’s classification of foreign-made inverters could increase industry interest in securing domestic inverter supplies, he said. On that front, “the storage space looks a lot healthier,” with companies such as U.S.-based EPC Power and Tesla operating significant domestic manufacturing capacity, and others such as Spain-based Power Electronics scaling up U.S. manufacturing.
Residential solar inverters are “in a good place,” Shangraw said, with SolarEdge, Enphase, and Tesla providing about 80% of the U.S. market needs. But the domestic manufacturing capacity for solar inverters for utility-, commercial-, and industrial-scale projects is less clear, he said, given that Chinese inverter makers hold about 60% of U.S. market share in that sector.
Large-scale solar developers could hope to earn waivers from the FCC on foreign-made inverters from non-Chinese companies such as SMA and Power Electronics, he noted. They could also anticipate expanded domestic manufacturing from U.S.-based Nextpower, which is acquiring the inverter and power conversion business of Spain-based Zigor and its U.S. subsidiary Apex Power; or from GE Vernova, which has opened an inverter factory in Pittsburgh and could expand capacity there, he said.
“The main thing is, we don’t know how impactful this is until we learn a bit more about the timeline for when these actual changes to the requirements” for existing inverters might occur that would “force companies to release new products,” he said. “I’d say if this was a hard deadline, and if there were no new imports allowed, we’d be in trouble.”
