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.
