On July 28, the Federal Communications Commission (FCC) expanded its Covered List to include foreign-made connected power inverters, according to Electrek. This regulatory action effectively halts the federal authorization required for these specific devices to be legally imported, marketed, or distributed within the United States. The policy shift specifically targets the integrated radio components contained within modern inverter systems rather than the underlying power electronics themselves.

This decision arrives at a period of vulnerability for the domestic energy market. Current projections from the testing firm Intertek CEA indicate that United States-based manufacturing facilities are expected to account for only 40% of the combined solar and battery demand throughout the upcoming year. By restricting new foreign-made models, the FCC is creating a potential supply chain bottleneck for developers and installers who rely heavily on imported hardware to fulfill existing project backlogs.

Why It Matters

The move marks a clear transition toward using telecommunications regulatory frameworks to address national security concerns within the energy sector. By targeting the radios—which are essential for grid connectivity and smart home integration—the FCC is effectively treating power infrastructure as a cybersecurity vector. Manufacturers now face the prospect of redesigning hardware to comply with domestic certification requirements, likely driving up costs. This strategy may provide a short-term boost to US domestic manufacturers, but it risks slowing the overall adoption rate of renewable energy infrastructure due to supply limitations.
