Sungrow is showcasing a suite of cutting-edge innovations at RE+ 2025. The lineup of new products released to the North American market includes the second-generation modular inverter for utility-scale PV projects; the next-generation PowerTitan 3.0, an AC Block BESS for large-scale energy storage applications; and the PowerStack 255CS BESS for commercial and industrial (C&I) energy storage. These innovations are set to contribute to local energy reliability and sustainability, reinforcing Sungrow's commitment to supporting the U.S. power grid and electric consumers with advanced, trusted, and compliant technologies.
Sungrow unveiled its 4.8 MW SG4800UD-MV-US modular inverter for North America. This pioneering solution combines the advantages of both central and string inverters, offering 800 kW per unit in a flexible design that reduces balance-of-system (BOS) costs. The split modular design allows inverter module replacement in under an hour, minimizing downtime and maximizing operational efficiency.
The system incorporates intelligent fault diagnosis for quick fault identification, and features self-cleaning air ducts to reduce daily maintenance needs. Spare Parts Management is simplified, as a single type of spare part is required for the inverter module. Designed for extreme durability, it delivers 100% power output in ambient temperatures up to 45degC (113degF), and carries a sealed NEMA 4X rating, ensuring enhanced reliability even in harsh environments.
Safety and performance are further strengthened through smart DC terminal temperature protection and a bottom pressure relief design. Additionally, its pioneering PV grid-forming and off-grid commissioning capabilities enable early commercial operation and improve Return on Investment (ROI), setting a new benchmark for utility-scale solar power systems in North America. Energy storage plays a crucial role in enhancing grid resilience and enabling greater integration of renewable energy.
For utility-scale applications, Sungrow has launched the next-generation AC Block Energy Storage System PowerTitan 3.0. Lower Lifetime LCOS: For the North American market, PowerTitan 3.0 delivers 6.9 MWh in a standard 20-foot ISO container, integrating batteries with the string PCS (Power Conversion System) for 2-8 hour designs. It features the first mass-produced 661Ah stacking LFP cell, with a 12,500-cycle lifespan for exceptional reliability and cost efficiency. The system debuts the industry's first 430 kVA liquid-cooled SiC PCS, achieving up to 99.3% maximum efficiency and up to 93.6% Round-Trip Efficiency (RTE) for a 4-hour duration (92% including auxiliary load).
Five-level State of Charge (SOC) balancing -- from cell to block -- maximizes usable capacity, while a back-to-back layout reduces footprint by 21% compared to the previous generation. And robust liquid-cooled thermal management reduces auxiliary power use and extends system lifespan. Safe and Reliable Safety is prioritized with 11-layer protection from cell Over-Voltage to PCS AC fusing, and Sungrow's ArcDefender??
technology to reduce arcing risks. The system meets all Authority Having Jurisdiction (AHJ) requirements in North America due to its state-of-the-art fire safety systems, and is fully pre-tested and certified. Rapid Deployment: The PowerTitan 3.0 is engineered for rapid deployment.
The system comes fully UL9540-certified before shipment. Enhanced on-site O&M tools further shorten commissioning timelines compared to the previous product generation. Built-in Grid-Forming Capabilities: Embedded with Sungrow's Stem-Cell Grid-Forming Tech 2.0, the PowerTitan 3.0 anticipates grid disturbances before they escalate, ensuring energy storage responds proactively.
The product delivers renewables and energy storage grid-forming synchronously, GW-scale energy storage grid-scale solar power storage grid-scale solar power systems.
