Sungrow Hits 1 TW of Solar Inverters as #1 Supplier in 2025 Rankings

For climate professionals tracking the infrastructure behind the clean energy transition, Sungrow's continued dominance in PV inverters is a leading indicator of solar's scaling trajectory. With 1 terawatt of deployed inverters—enough to power roughly 200 million homes—Sungrow is literally the backbone of a significant fraction of the world's solar generation, directly displacing fossil fuel consumption and cutting CO2 emissions.

Sungrow has once again been ranked as the global leader in PV inverter shipments for 2025, according to the latest annual report from S&P Global. The announcement, made via a press release on August 9, 2026, underscores the Chinese company's continued dominance in a market critical to the solar energy supply chain. PV inverters—the devices that convert direct current from solar panels into alternating current for the grid—are essential components of any photovoltaic system, and shipment rankings serve as a proxy for installed solar capacity worldwide. Sungrow's retention of the top spot for another year signals not only its own operational strength but also the sustained global appetite for solar energy deployment.

Sungrow has once again been ranked as the global leader in PV inverter shipments for 2025, according to the latest annual report from S&P Global.

The company paired the ranking announcement with two notable technological debuts at SNEC 2026: the world's first PowerMatrix inverter and the first field-validated solution for wide-frequency oscillation in power systems. The PowerMatrix architecture represents a design departure from conventional string and central inverter topologies, promising higher efficiency, lower balance-of-system costs, and superior stability across diverse applications—from utility-scale plants to commercial rooftops. The wide-frequency oscillation solution addresses a growing technical challenge as renewable penetration increases: grid instability caused by interactions among inverter-based resources. By field-validating a remedy, Sungrow positions itself at the forefront of grid integration technology, a crucial differentiator as regulators and utilities grapple with high-renewable grids.

These innovations are supported by a research and development engine where approximately 40% of Sungrow's workforce are technical professionals. With a global footprint extending to more than 100 countries and regions, four manufacturing bases, and an accumulated grid-connected experience exceeding 1 terawatt (TW), the company has built an unmatched scale. Its service network—520 locations, over 1,200 technical service engineers, and more than 400 authorized partners—provides a moat of localized support that competitors find difficult to replicate quickly. This combination of scale, innovation, and service underpins its top ranking.

From a market perspective, the PV inverter industry has been consolidating around a handful of major players, with Sungrow, Huawei, and a few others capturing the lion's share. S&P Global's ranking methodology typically accounts for both shipments and grid-connected capacity, so Sungrow's #1 spot reflects both volume and real-world deployment. The 1 TW milestone is particularly telling: it implies that Sungrow inverters are installed across roughly one-fifth of the world's cumulative solar PV capacity (assuming global installed capacity of about 5 TW by early 2026). The company's ability to serve such a massive base gives it valuable data and operational feedback that further fuel product improvements.
