FCC bans foreign-produced solar inverters


This means any solar or battery storage project relying on an inverter made outside the United States that has not already received an official FCC ID cannot legally turn on or interconnect. Because there is no phase-in period, grandfather clause, or grace window, the regulatory pipeline is frozen today, forcing developers to halt active procurements and find new hardware vendors. Crucially, this applies strictly to new inverter model filings rather than an absolute freeze on all foreign-built components. Find a fact sheet from FCC here.

The action effectively overrides the Department of Energy analysis from January 2026, which inspected 30 Chinese inverters and found zero evidence of malicious hardware. …

The immediate practical result is a massive equipment shortage that will delay upcoming commercial and utility projects. Department of Energy data shows that domestic manufacturers supply only seven percent of the U.S. solar inverter market, leaving a 93% deficit that cannot be filled by local factories anytime soon. This impact will primarily materialize down the line as manufacturers introduce new product refreshes or next-generation hardware designs that require fresh FCC grants.

The hardware blockade hits right as developers plan to connect more than 58,000 MW of new solar and storage over the next year. Without certified inverters, fully built solar farms will sit dark and unable to feed electricity to the grid.
