Full Connectivity and Empowerment in Energy Management

At this year's Intersolar Europe 2026, Sungrow, a top provider in photovoltaic (PV) inverters and energy storage solutions, introduced its cutting-edge iNexGrid all-scenario microgrid solution. This innovative offering demonstrates Sungrow's commitment to reliability, efficiency, and sustainability across different energy application scenarios.

Introduction to iNexGrid

The iNexGrid solution embodies a comprehensive approach to microgrid management by integrating multiple energy sources and advanced technologies. As microgrids have become essential for achieving energy security and advancing carbon neutrality, Sungrow has tailored its solution to address the unique challenges presented in diverse operational environments, such as mining, automotive industrial (AIDC), commercial-industry (CI), and off-grid island applications.

Challenges and Innovations

Different microgrid scenarios face distinct challenges:

• - Mining Microgrids: These require effective coordination of power sources under highly variable conditions.
• - AIDC Microgrids: They must manage millisecond-level power surges without compromising power quality.
• - CI Microgrids: They deal with large energy demands and fluctuating power charges, which can negatively affect profitability.
• - Island Microgrids: These often depend heavily on diesel fuel, particularly in challenging environments.

Luyao Shi, Product Director at Sungrow Smart Energy, stated, "Across various applications, clients seek stable operations and intelligent functionalities to foster growth. Our iNexGrid solution offers robust support for reliable microgrid functions."

Five-Layer System Protection

Central to the iNexGrid is its innovative Five-Layer System Protection. This architecture integrates Sungrow's core technologies, including PV, wind energy, energy storage, electric vehicle charging, and sophisticated cloud platforms. Key components of this protective framework feature:
1. Proactive Protection: Utilizing AI for forecasting energy demands and integrating edge-cloud hybrid algorithms, it enhances prediction accuracy and significantly reduces power deficits, enabling quicker project payback.
2. Localized Support: The microgrid implements virtual excitation controls and flexible inertia support to ensure rapid responses to minor disturbances, preventing disruptions for sensitive equipment.
3. Coordinated Control for Major Disturbances: It integrates seamless switching between grid-connected and off-grid operations, stabilizing critical loads effectively.
4. Emergency Control Protocols: This will coordinate energy sources during faults to ensure emergency control and maintain functionality.
5. Self-Healing Capabilities: Even in instances of significant grid failures, the system can promptly restore power within one minute, thanks to advanced black start technology.

Customized Microgrid Solutions

Sungrow's microgrid offerings are adaptable, designed to cater to the specific needs of different sectors:

• - For mining operations, dynamic adjustments between storage and generator outputs achieve a reliability rate of 99.99%.
• - AIDC microgrids will have controlled frequency adjustments to mitigate power swings.
• - CI microgrids benefit from AI-optimized dispatch strategies to lower peak energy costs.

Proven Success and Global Impact

Sungrow has successfully implemented microgrid solutions in various international projects, including installations in Zambia and Namibia, showcasing their extensive operational capacity with over 1,000 GW installed globally. Sungrow's efficient design processes and advanced simulation tools greatly facilitate project delivery and performance improvement.

As Luyao Shi concluded, "The iNexGrid name symbolizes our vision of future microgrids evolving beyond standalone systems to become agile, intelligent hubs capable of adapting and integrating with various energy sources. As technology advances, so too will our commitment to efficiency and sustainability in the global energy landscape."

With its iNexGrid microgrid solution, Sungrow is poised to redefine energy management standards, paving the way for smarter and more sustainable energy infrastructures worldwide.
