Overview

  • U.S. experts uncovered undocumented communication devices in Chinese-made solar inverters and batteries, potentially enabling remote manipulation of energy infrastructure.
  • The Department of Energy is addressing disclosure gaps with Software Bill of Materials requirements and encouraging domestic manufacturing for secure supply chains.
  • Legislation in the U.S., including the Decoupling from Foreign Adversarial Battery Dependence Act, seeks to limit reliance on Chinese energy equipment by 2027.
  • European nations like Lithuania have already enacted laws restricting remote access to Chinese-made renewable energy systems to safeguard critical infrastructure.
  • Huawei, the global leader in inverter shipments, and other Chinese firms face scrutiny due to legal obligations to cooperate with state intelligence, raising concerns over their dominance in renewable energy markets.
