Huawei and Sungrow have emerged as the top two global solar inverter manufacturers for the first half of 2025, with scores of 93.9 and 93.7, according to a report published by Wood Mackenzie.

The ranking places Germany’s SMA at third, followed by Austria-based Fronius in fourth and China’s Ginlong/Solis in fifth. The remainder of the top ten includes China’s GoodWe in sixth, Japan’s TMEIC and Israel’s SolarEdge sharing seventh place, China’s Aiswei/Solplanet in ninth, and US-based Enphase completing the list in tenth.

Global Solar Inverter Manufacturer Rankings H1 2025 evaluate 23 leading manufacturers from seven countries based on eight performance criteria, accounting for approximately 90 percent of global shipment volumes in 2024.

A significant finding from the H1 2025 ranking is the maturation of ESG practices. Six of the top 10 companies achieved an EcoVadis ranking of silver or higher, placing them in the top 15 percent of companies globally for sustainability.

Furthermore, all top 10 manufacturers now offer warranty extensions of 20 years or more. This shift reflects increased confidence in product longevity and a commitment to matching the operational lifespan of solar modules, reducing long-term risk for developers and asset owners, the report stated.

It further added that despite sustained pricing pressure, innovation remains a key competitive differentiator. Eight of the top 10 inverter manufacturers reinvest more than six percent of revenue into Research & Development, driving advances in digitalisation, power-conversion technologies and faster product refresh cycles, alongside expanding patent portfolios, it said.

“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.”

Moreover, 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 US, Southeast Asia and Israel.

“The strongest performers are those leveraging regionalised assembly strategies,” Shen commented. “This strategic positioning allows manufacturers to comply with local content requirements and navigate import barriers while maintaining their supply reliability.”

Each of the top ten companies has also secured Wood Mackenzie’s Grade A inverter manufacturer certification — a designation intended to signal suppliers that demonstrate strong operational resilience and adherence to international procurement best practices. To earn the distinction, manufacturers were required to satisfy at least five of Wood Mackenzie’s defined evaluation benchmarks.

A further five solar inverter suppliers have additionally been awarded Grade A status: China-based Hoymiles, Kstar, Sofar and Chint Power Systems, along with Spain’s Ingeteam.
