Lawmakers warn Huawei's grip on solar inverters risks Europe's energy security, urging the Commission to restrict 'high-risk' vendors as member states step up safeguards. . While presenting the proposals in European Parliament, the commission's Executive Vice-President for Tech Sovereignty, Security and Democracy, Henna Virkkunen, said dependency on a very limited number of solar inverter suppliers could “pose a significant security risk. ” Is the European Union. . The fears center around solar panel inverters, a piece of technology that turns solar panels' electricity into current that flows into the grid. China is a dominant supplier of these inverters, and Huawei is its biggest player. The reversal came after a months-long saga marked by an anti-corruption investigation and mounting. . On May 1, 2025, Lithuania officially implemented the amendment to the Electricity Law, requiring that new photovoltaic projects above 100kW must use inverters that meet national safety standards, and existing projects must be transformed before May 2026.
