1. Tighter U.S. restrictions on imported inverters, imposed over national security concerns by the Federal Communications Commission (FCC), are threatening the market position of Chinese manufacturers and prompting strategic reassessments. The measures affect a market where Chinese firms accounted for half of U.S. shipments in 2024, and analysts warn they could redirect trade flows and raise costs for U.S. buyers, though immediate supplier earnings impact may be limited.

2. Inverters, which convert direct current to alternating current for the power grid, are critical in solar, battery-storage, and wind systems. On July 28, the FCC updated its Covered List to ban foreign-made utility inverters with remote communications capabilities, citing supply-chain security and the need to bring critical manufacturing back to the U.S., with reports indicating concerns that China could use the devices to disrupt power supplies. On Aug. 20, the FCC narrowed the restrictions to grid-tied inverters with remote communications functions, providing exemptions for products meeting specified domestic manufacturing requirements.

3. The U.S. inverter market is heavily import-dependent. Wood Mackenzie analysis from August shows the U.S. received over 200 gigawatts of commercial, industrial, and utility-scale solar inverters over the past decade, with more than 90% imported, including over 70 GW supplied by Chinese-headquartered manufacturers largely from Southeast Asian factories. A 2026 report from a U.S. Department of Energy national laboratory put Chinese manufacturers’ share of U.S. shipments at 50% in 2024. Wood Mackenzie analyst Joe Shangraw stated the FCC’s intent is clear: the U.S. government views reliance on foreign inverters as a national security risk due to cybersecurity and economic concerns.

4. Chinese inverter stocks have fallen due to the shifting policy outlook. Since late July, shares of Sungrow Power Supply Co. Ltd. have declined about 37%, while GoodWe Technologies Co. Ltd. and Jiangsu Chint Power Technology Co. Ltd. have lost 28% and 10.6%, respectively. [para. 7]
5. Direct exports from China to the U.S. were already declining amid higher tariffs and a shift toward Southeast Asian production. In 2025, China shipped 3.4 million inverters to the U.S., worth 2.05 billion yuan ($307 million), accounting for 3% of total inverter exports. The U.S. fell from China’s fourth-largest export destination in 2021 to its eighth-largest in 2025. In the first nine months of 2026, U.S. shipments fell 10% year-on-year to 2.4 million units, with value declining 3.5% to 1.4 billion yuan, per Chinese customs data. [para. 8][para. 9]
6. The near-term impact may be limited. JPMorgan noted that the bans cover inverters and energy storage systems, but do not affect existing models already FCC-approved, expecting earnings impacts mainly over the medium term. Nomura Securities warned that compliance uncertainty could prompt U.S. buyers to switch suppliers, eroding overseas manufacturers’ market share even without additional restrictions. [para. 10]
7. Sungrow, which held a leading 23% U.S. market share in 2022 and retained its lead in 2024, acknowledged the pressure. On Aug. 28, the company said existing products had a few years remaining but geopolitical uncertainty would gradually reduce its U.S. business, prompting a focus on other regional markets. The U.S. historically contributed 15% to 20% of Sungrow’s revenue, according to an October 2025 disclosure. It also flagged greater uncertainty from 2028, as signed orders through 2027 remain secure, but projects subsidized under the Inflation Reduction Act will begin expiring in late 2028, and from 2029 new projects must comply with rules barring prohibited foreign entities from qualifying for benefits. [para. 11][para. 12][para. 13]
8. Meanwhile, U.S. inverter manufacturing capacity is expanding. PV Tech Research estimates annual capacity surpassed 60 GW in Q3 2026 and will exceed 70 GW by year-end. EPC Power opened a South Carolina plant in July, adding 27 GW of annual capacity, while Spain’s Power Electronics began building a Texas facility in September expected to reach 40 GW of annual capacity. [para. 14][para. 15]
9. Chinese manufacturers remain cautious about U.S. investment. Sungrow stated it was not considering a U.S. manufacturing investment due to what it described as an unfair competitive environment, high costs, and customer skepticism, instead seeking partnerships in components, services, and small systems. A shift toward domestic production is expected to raise costs for U.S. buyers, with Wood Mackenzie forecasting inverter price increases by 2027 as lower-cost imports give way to domestic alternatives. Sungrow noted that China took 20 years to build a complete inverter supply chain, estimating the U.S. would need at least five years to develop a mature domestic industry.
