Sungrow Sets a New Benchmark in Renewable Energy

Sungrow, a leader in renewable energy technology, recently made headlines by becoming the first globally to earn the VDE-AR-N 4105:2026 certification for its SHT series hybrid inverter. This certification, awarded by the renowned TÜV Rheinland, is a testament to the product's compliance with Germany's rigorous low-voltage grid connection standards that took effect on March 1, 2026.

Within weeks of the certification's announcement, Sungrow's swift execution and robust technical capabilities were highlighted. The VDE-AR-N 4105:2026 standard is notable not just for its comprehensiveness but also for its influence on the European residential energy sector. It expands on the previous standards by covering a wider power range and introducing more stringent operational requirements, especially in dealing with complex grid conditions.

The assessment process required a comprehensive set of tests, which the SHT hybrid inverter successfully navigated. Key areas evaluated included:

• - PAV (Voltage ride-through)
• - E monitoring (feed-in limitation)
• - Reactive power supply
• - Network and system protection

The Sungrow technical team asserts that the SHT series already integrated many of the updated standard's requirements ahead of the certification, needing only minor tweaks to adapt to new parameters. This forward-thinking approach underscored the company’s proactive research and development strategies.

The certification comes against the backdrop of a rapidly evolving energy landscape. With increasing deployment of distributed energy resources across Europe and beyond, the functionality and adaptability of grid systems are coming under significant pressures. As these systems become more complex, the demands on inverters for precise power regulation and dynamic grid support intensify.

Sungrow's engineering team was well aware of these trends during the design phase of the SHT series, leading them to set ambitious performance targets that ensured compliance with the new standards with ease. This foresight not only cemented their first-mover advantage in the market but also provided other industry players with a valuable reference point for meeting new regulatory requirements.

Dr. Philip Yu, Principal Engineer of Sungrow's Residential Business Unit, shared insights on the achievement, stating, "Our SHT hybrid inverter series has achieved over 1 GW in global shipments to date, playing a key role in energy solutions for nearly 80,000 households and businesses worldwide. We remain committed to advancing technological innovation in grid integration and elevating our product capabilities to meet ever-stricter grid standards, thus enabling a more reliable energy future."

Sungrow's dedication to renewable energy spans over 29 years, with credibility built on installing more than 1000 GW of power electronic converters worldwide as of December 2025. Recognized as the world's most bankable PV inverter and energy storage provider by BloombergNEF, the company remains at the forefront of clean energy initiatives globally, underpinned by a network of 520 service outlets to ensure optimal customer satisfaction.

With this groundbreaking certification, Sungrow is not only setting high performance benchmarks for its products but also contributing significantly to the development of more resilient and efficient energy systems. This progress reinforces their mission of fostering a sustainable future through advanced technology and exceptional service. For more details, visit Sungrow's official website.
