Sungrow Sets a New Benchmark with World’s First VDE EMC Certified Microinverter

Sungrow’s Historic Achievement: The First VDE EMC Certified Microinverter

Sungrow Power Supply Co., Ltd. has made a remarkable breakthrough in renewable energy technology by attaining the world’s first VDE EMC certification for its microinverter. This landmark achievement not only exemplifies Sungrow's commitment to safety and innovation but also establishes new standards for electromagnetic compatibility (EMC) in the sector.

Electromagnetic compatibility is essential for ensuring the stability and safety of residential photovoltaic (PV) systems. Inadequate EMC performance can lead to various issues, from system malfunctions to interference with household electronics and wireless networks. Therefore, achieving high EMC standards is critical for the reliability of solar energy systems.

Rigorous Testing and Unmatched Performance

The certification was granted following extensive testing conducted at the VDE laboratory in Germany. Sungrow's microinverter was evaluated against several international benchmarks, including DIN EN IEC 61000-6-1, DIN EN IEC 61000-6-3, and EN 301 489-17, focusing on ten key performance metrics such as susceptibility to electromagnetic interference and immunity to power-frequency magnetic fields. The microinverter not only met but surpassed these stringent requirements across the board, showcasing impressive stability and reliability.

Sungrow’s microinverter incorporates advanced technological features that enhance its EMC performance. For instance, its soft-switching topology minimizes electromagnetic interference right from the source, while the all-metal casing and high-conductivity sealing materials effectively shield against electromagnetic radiation. The device is designed to maintain optimal performance even under adverse conditions, mitigating issues such as harmonic distortion.

Leadership in Sustainable Energy

According to Sven Öhrke, a Board Member of VDE Institute, Sungrow has exceeded expectations during the testing process. With an increasing adoption of balcony PV systems across Europe, the successful EMC certification positions Sungrow as a leader in this innovative segment of the solar market.

Beyond its exceptional EMC capabilities, Sungrow's microinverter stands out due to its superior efficiency. It has been engineered to deliver full power output even in extreme conditions, enhancing overall energy yields by approximately 2%. The user-friendly plug-and-play design has been shown to improve installation efficiency by up to 30%, further simplifying the transition to clean energy. Notably, the microinverter integrates intelligent self-checking and one-click network configuration functionalities.

Having undergone over 200 authoritative tests and achieved numerous international certifications, including IEC 61140, IEC 62109, and IEC 63027, Sungrow's microinverters have become vital in enabling homes worldwide to adopt renewable energy solutions.
