Huawei and Sungrow ranked as the top two global solar inverter manufacturers for the first half of 2025, based on the “Global Solar Inverter Manufacturer Rankings H1 2025” report from Wood Mackenzie. The rankings evaluate 23 leading manufacturers from seven countries based on eight performance criteria. The manufacturers accounted for approximately 90% of global shipment volumes in 2024.
“The 2025 global inverter landscape is led by a diverse group of power-electronics leaders combining scale with innovation,” said Timothy Shen, senior research analyst at Wood Mackenzie. “Increasingly, competitive advantage is defined not just by shipment volume, but by capabilities across pioneering environmental, social and governance (ESG) initiatives, service quality and stable supply chains.”

Based on operational sustainability studies, six of the top 10 companies achieved an EcoVadis ranking of silver or higher, placing them in the top 15% of companies globally for sustainability. Additionally, all 10 manufacturers now offer warranty extensions of 20 years or more.
Eight of the top 10 inverter manufacturers reinvest more than 6% of their revenue into research and development, driving advances in digitalization, power-conversion technologies and faster product refresh cycles, alongside expanding patent portfolios.
Manufacturing footprints are shifting in response to evolving global trade dynamics. Four of the top 10 solar inverter manufacturers now provide global production coverage, with facilities spanning China, Europe, India, the United States, Southeast Asia and Israel.
“The strongest performers are those leveraging regionalized assembly strategies,” Shen said. “This strategic positioning allows manufacturers to comply with local content requirements and navigate import barriers while maintaining their supply reliability.”

Grade A is awarded to manufacturers that meet Wood Mackenzie’s benchmark for industry best practice, demonstrating consistent and verifiable performance across the key criteria assessed in this ranking. To achieve Grade A status, a manufacturer must meet at least five of the defined benchmarks, reflecting a level of capability that helps reduce execution and operational risk for developers, EPCs and asset owners.
Wood Mackenzie reported last month that it expects the global inverter market to shrink in the next two years. The U.S. market is experiencing a downturn due to policy volatility in solar.
