Company patents
Sungrow Power Supply Co., Ltd.
Sungrow Power Supply Co., Ltd. demonstrates a strong and consistent focus on core electrical power technologies, with Power Distribution & Storage (37.3% of portfolio) and Power Conversion (DC/AC, DC/DC) (31.2% of portfolio) dominating its patent strategy. While there was significant growth in Photovoltaic (Solar Cells) patents in 2024 (YoY +166.7%) and Batteries & Fuel Cells in 2025 (YoY +166.7%), indicating an emerging focus on renewable energy components, the sharp decline in patent filings across nearly all categories so far in 2026 (e.g., Power Distribution & Storage down 69.4% YoY, Power Conversion down 72.7% YoY) suggests a potential shift in R&D investment or a strategic re-evaluation, though 2026 data is partial.
