The background Of our story
To meet the growing demand for ultra-large wind turbines, Sungrow has launched its first 1800V wind power converters — now officially in mass production. Recently, the first 1800V/10MW units were successfully shipped, marking a new chapter in voltage upgrades for wind power systems.
A Unique Challenge
1.Current Losses in Large Turbines 1140V systems cause high current and cable losses in 10MW+ turbines, limiting efficiency. 2.Supply Chain Gaps in High-Voltage Components Key 1800V components were scarce; localized sourcing was needed to scale reliably.
A Smart Solution
1: Voltage Upgrade to 1800V By raising the system voltage to 1800V, Sungrow cut current by 37%, reduced cable losses, and improved slip ring performance for large turbines. 2: End-to-End Localization of Core Components Through joint R&D with supply chain partners, Sungrow localized key parts from IGBT modules to LV devices, ensuring delivery and reliability at scale.
Setting a New Benchmark for High-Power Wind
Sungrow’s 1800V converter marks a key step toward next-generation wind power, offering higher efficiency, better reliability, and scalable potential for 10–15MW onshore and 15MW+ offshore turbines. It also lays the technical foundation for future applications in deep-sea wind, hybrid systems, and green hydrogen.
