Yes. Growatt is organized in China, a covered nation under the FEOC rules, which makes it a foreign entity of concern for IRA clean-energy tax credit purposes. It is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List). Is Growatt a Foreign Entity of Concern?

Research-based supply-chain map compiled from public sources - not an audited bill of materials. Tiers reflect the standard industry structure for this product. Sourcing risk on a node describes where that input is typically mined or refined; it is not a FEOC determination for Growatt, and it is not a screening result for the node itself unless a federal listing is cited against it. Verify against primary documentation before making a compliance determination.
