45X-eligble inverters are not part of foreign ban, FCC clarifies
The Federal Communications Commission has adjusted its recent ban on foreign-made solar inverters, the devices that convert power from solar panels into electricity your home can use. Last month the FCC barred new imports of foreign-produced inverters, citing cybersecurity and supply-chain concerns. It has now clarified which inverters count as "foreign." Previously, an inverter counted as domestic only if it had 65% U.S.-made content. Now, any inverter that qualifies for a federal manufacturing tax credit known as 45X will be treated as domestic, regardless of where the company making it is based. Manufacturers claiming that credit already can't get help from certain foreign entities the government considers a risk, so officials decided those inverters don't pose the same security concern. The FCC also clarified that the ban covers both wired and wireless inverters, since either type could potentially be accessed remotely. For homeowners, this mostly affects the solar equipment market rather than existing systems. The ban applies only to new inverter models going forward. Any inverter already installed on a home, or already approved by the FCC before this rule, can keep operating as normal. If you're planning a new solar installation, this change could affect which inverter brands and models are available, since it opens the door to some foreign-made inverters that meet the tax-credit standard, while still blocking others that don't.
AHRI, ACCA Seek Delay As HVAC GFCI Deadline Nears
A new electrical code rule set to take effect Sept. 1 would require GFCI protection — the same type of shock-safety device used in outlets near sinks — on many outdoor air conditioners and heat pumps. Two industry groups, AHRI and ACCA, are asking for a two-year delay because testing shows these devices often don't work well together. The mismatch can cause "nuisance trips," where the GFCI shuts off a working, safely installed AC or heat pump for no real reason. This matters for homeowners because a nuisance trip means your cooling system suddenly stops, and you'd need to find and reset a tripped breaker or device to get it running again. The groups pushing for the delay point out that this isn't just a hassle: during a heat wave, a system that shuts off unexpectedly can be dangerous, especially for older adults or people who can't easily tell what went wrong or reset the equipment themselves. They cite Maricopa County, Arizona data showing most 2024 heat deaths there happened in homes where the AC wasn't working or wasn't running. There's also a supply issue — the newer GFCI devices built to work with modern HVAC equipment aren't yet available everywhere. The requested extension would push the deadline to September 2028 to allow more testing. A decision from the National Fire Protection Association is expected after a public comment period closes Sept. 9. If the delay isn't granted, homeowners installing or replacing qualifying outdoor equipment after Sept. 1 could be more likely to encounter this tripping problem.
Trump declares emergency, moves to block some foreign-made equipment from grid
President Trump signed an executive order declaring a national emergency over the security of the country's power grid. The order sets up rules to block utilities from connecting some foreign-made equipment to the "bulk power system" — the large-scale network of power plants and transmission lines that moves electricity across the country, as opposed to the local wires that run to individual homes. Equipment covered includes transformers, batteries, inverters, and related software. The Department of Energy has 120 days to write the specific rules. The order also opens the door to restrictions on equipment already installed, meaning the Energy Secretary could set conditions on how existing foreign-made grid gear keeps operating or gets serviced. The stated concern is sabotage or unauthorized access tied to foreign-made components, especially as data centers and AI drive up electricity demand. China currently makes 80% or more of the world's supply of some grid equipment, including lithium-ion battery cells and certain solar parts. This order targets the large-scale grid, not the equipment inside your house, so it does not directly affect home systems like rooftop solar panels or backup batteries. But it could ripple into utility costs and supply chains over time, since utilities plan to spend over a trillion dollars on grid upgrades in the next few years. Equipment manufacturers say they still need clarity on details, particularly how software and digital products would be judged for country of origin. There is no homeowner deadline or program tied to this news right now.
