Introducing PowerStack 3.0

At the recently held Global Energy Pioneer Summit (GEPS) 2026, Sungrow, a global leader in photovoltaic (PV) inverters and energy storage systems, proudly presented its next-generation PowerStack 3.0 series. This cutting-edge solution aims to revolutionize the commercial and industrial (CI) energy storage landscape by offering unprecedented versatility and intelligence.

The Scene-in-One Concept

PowerStack 3.0 signifies a shift from traditional energy storage systems towards a more integrated and adaptable approach, termed the “Scene-in-One” solution. Rather than relying on standalone devices, this innovative system configuration is tailored to meet specific application requirements. Sungrow aims to address the increasingly diverse needs of CI energy storage applications, making it easier to deploy and manage energy systems across various scenarios.

Multi-Scenario Docking

One of the standout features of PowerStack 3.0 is its industry-first multi-scenario dock, which includes four specialized modules:

• - PCS (Power Conversion System) Module
• - Solar Module
• - Charging Module
• - Microgrid Module

This modular design allows users to customize their system configurations and supports multiple revenue streams while significantly simplifying project deployment. By focusing on a unified yet flexible architecture, users can maximize energy output and efficiency in an increasingly competitive environment.

Versatile System Configurations

• - Flexibility for Varying Needs: The PowerStack 3.0 allows for the combination of PCS power modules in varied configurations, enabling a seamless switch between 2-hour and 4-hour discharge scenarios. This adaptability reduces the need for extensive equipment inventory and lower management costs.

• - Integrated PV-Storage: The system can directly manage PV power conversion without necessitating an extra inverter, thanks to its innovative PV-storage module, facilitating simplified installation.

• - Faster Project Implementation: By enabling DC coupling within the entire framework of PV, energy storage, and charging, the PowerStack 3.0 drastically shortens project timelines and reduces installation costs.

• - Microgrid Capability: Designed to tackle challenges posed by weak grids, the microgrid module ensures uninterrupted power supply during grid outages, implementing a seamless transition between grid-connected and off-grid operations without additional equipment.

AI-Powered Optimization

The integration of Bubbly, Sungrow’s AI assistant, elevates the PowerStack 3.0 experience by providing intelligent solutions throughout the project lifecycle. This assistance spans planning, commissioning, operation, and maintenance aspects, thus offering enhanced decision-making support and workflow efficiency.

• - Tailored Design Proposals: Bubbly combines satellite imagery and 3D modeling to generate specific design proposals in under 30 seconds, including technical specs and cost analysis.

• - Rapid Commissioning: The commissioning process can be completed in just 3 minutes, streamlining configurations and limiting human errors significantly.

• - Higher Financial Returns: By leveraging forecasts to optimize operational strategies, Bubbly enhances efficiency, yielding returns greater than 12% over traditional methods.

• - Proactive Maintenance Monitoring: Continuous system checks identify potential risks and supply detailed maintenance recommendations swiftly, ensuring operational reliability and longevity.

Comprehensive Upgrades

The PowerStack 3.0 architecture focuses on critical criteria such as space utilization, environmental resilience, operational efficiency, and system safety.

• - Space-Efficient Installation: With a maximized energy density of 256 kWh/m², the system supports diverse installation configurations to optimize space usage, reducing the required footprint by 43% compared to its predecessor.

• - Environmental Resilience: Rated IP55 for ingress protection and C5-level for corrosion protection, this system is able to function in extreme temperature conditions, ranging from -30°C to 50°C.

• - Efficiency and Reliability: Equipped with a self-developed SiC PCS, the system boasts a conversion efficiency of up to 99.2%, ensuring effective energy conversion and usage.

In conclusion, the launch of the PowerStack 3.0 represents a remarkable advancement in the energy storage sector, underlining Sungrow's commitment to delivering intelligent and integrated solutions designed for diverse application needs. Dr. Cao Wei, GM of Sungrow's CI ESS Product Line, emphasized that this new product is more than just an upgrade; it’s a complete ecosystem crafted to maximize value throughout its operational life.
