US adds foreign-produced solar inverters to FCC Covered List

The restriction targets prospective authorizations for new networked inverter models, including hardware used in solar and battery storage projects. The policy is framed around cybersecurity concerns tied to remote communications and firmware updates, while hardwired or fully air-gapped field inverters fall outside the described scope. The issue matters for developers because domestic manufacturers currently cover only a small share of the US inverter market, so future product refreshes could face procurement delays.
