Overview

  • US engineers discovered undocumented communication modules in Chinese-made solar inverters that could bypass firewalls and enable remote shutdowns.
  • The German cybersecurity agency BSI has called for EU-wide certification and the exclusion of non-trusted manufacturers from the European market.
  • China's government denies the allegations, calling them defamatory, while concerns grow over the strategic dependence on Chinese renewable technology.
  • Over 200 GW of Europe's solar capacity relies on Chinese inverters, with Huawei holding a 29% share of the global inverter market in 2022.
  • US utilities are preparing for potential restrictions on Chinese inverters, following Lithuania's November 2024 ban on Chinese firms in energy infrastructure.
