How do we ensure renewable energy systems are both efficient and safe for everyday use? Sungrow, a global leader in renewable energy technology, answers this question with its latest achievement: becoming the world’s first company to receive the prestigious VDE EMC Certificate for its microinverter. With this milestone, Sungrow’s microinverter sets a new global benchmark for safety, reliability, and innovation in residential photovoltaic (PV) systems.
The certification wasn’t just another routine process—it involved rigorous testing under strict international standards. Sungrow’s microinverter emerged as a standout performer, surpassing even the most stringent requirements and demonstrating exceptional stability in challenging electromagnetic environments.
Understanding EMC: Why It’s Critical
Electromagnetic compatibility (EMC) is a cornerstone of effective PV systems. Without proper EMC performance, households risk system malfunctions, interference with appliances and wireless networks, and even potential safety hazards. These challenges can undermine the reliability and appeal of renewable energy adoption.
Sungrow addresses this critical need with a microinverter that not only meets but exceeds global EMC standards. Ensuring seamless operation in complex environments, allows households to embrace clean energy without compromising on safety or convenience. This innovation highlights Sungrow’s vision of creating solutions that are as user-friendly as they are effective.
Sven Ohrke, Board Member of VDE Institute and CEO of VDE Global Services, reported the importance of this breakthrough, stating: “With balcony PV systems gaining popularity across Europe, we are delighted to witness Sungrow’s microinverter successfully passing our rigorous testing. Sungrow truly impressed us during the tests, not only meeting but surpassing the toughest international standards.”
Behind the Design: Innovations That Set Sungrow Apart
What makes Sungrow’s microinverter a game-changer? It’s all in the design. The microinverter incorporates cutting-edge features that make it both efficient and robust. One standout innovation is the soft-switching topology, a design that minimizes electromagnetic interference (EMI) at the source.
Additionally, the device is housed in an all-metal casing and uses high-conductivity sealing materials to block electromagnetic radiation effectively. Advanced control strategies further optimize its performance under extreme conditions, such as operating at the maximum (PVmax) or minimum (PVmin) photovoltaic input. This ensures the microinverter remains reliable and efficient, even in challenging scenarios.
A Product That Delivers Beyond Expectations
Sungrow’s microinverter doesn’t stop at addressing EMC requirements—it also delivers superior energy efficiency, user-friendly installation, and outstanding reliability. It is engineered to perform at full power output even in non-ventilated environments with temperatures as high as 60°C, increasing energy yields by approximately 2%.
Installation has never been easier, thanks to its plug-and-play design, which reduces setup time by 30%. Features such as intelligent self-checking and one-click network configuration further simplify the process, making it accessible even for users new to renewable energy systems.
This microinverter has undergone over 200 authoritative tests and achieved 12 international certifications, including IEC 61140, IEC 62109, and IEC 63027. Each certification underscores its robustness, safety, and reliability, cementing its status as a trusted choice for households worldwide.
Setting a Global Standard
The certification journey followed international standards such as DIN EN IEC 61000-6-1, DIN EN IEC 61000-6-3, and EN 301 489-17, focusing on 10 critical performance metrics. These included conducted and radiated susceptibility, as well as immunity to power-frequency magnetic fields. Sungrow’s microinverter not only passed these tests but also outperformed the standard requirements across all metrics.
This achievement is a testament to Sungrow’s dedication to pushing boundaries in renewable energy technology. The combination of advanced engineering and rigorous testing has set a new global standard for microinverters, proving that high performance and safety can coexist in a single product.
