Sungrow Unveils Innovative Products at the RE+ Tradeshow
As part of its commitment to advancing renewable energy solutions, Sungrow has announced the debut of several groundbreaking products slated for display at the RE+ tradeshow. Among these innovations are a second-generation modular inverter for utility-scale photovoltaic (PV) projects, an advanced AC Block Battery Energy Storage System (BESS) called PowerTitan 3.0, and the PowerStack 255CS BESS tailored for commercial and industrial (C&I) energy storage applications. Each product is designed to enhance efficiency, safety, and reliability in energy management.
4.8-MW Modular Inverter: The SG4800UD-MV-US
The centerpiece of Sungrow’s offerings is the 4.8-MW SG4800UD-MV-US modular inverter, specifically engineered for the North American market. This innovative inverter combines the benefits of both central and string inverters, delivering a robust 800 kW per unit. It features a flexible design that significantly reduces Balance of System (BOS) costs and operational downtime.
One of the significant advantages of the SG4800UD-MV-US is its split modular design, which allows for the replacement of inverter modules within an hour. This adaptability is crucial for optimizing operational efficiency, as it minimizes downtime for utility-scale solar projects. To further bolster its reliability, the inverter incorporates intelligent fault diagnosis, enabling rapid fault identification while also featuring self-cleaning air ducts that reduce daily maintenance needs.
Designed to withstand extreme conditions, the modular inverter delivers 100% power output even in ambient temperatures up to 45°C (113°F). Its NEMA 4X rating ensures that it can operate reliably in harsh environmental conditions. Safety features include smart DC terminal temperature protection and a bottom pressure relief design, safeguarding the system from potential hazards. Furthermore, the inverter’s pioneering PV grid-forming and off-grid commissioning capabilities allow for expedited commercial operation, improving the overall Return on Investment (ROI) for solar power installations across North America.
PowerTitan 3.0: Next-Generation Energy Storage
For those looking to optimize energy storage further, Sungrow proudly introduces the PowerTitan 3.0, a next-generation AC block energy storage system designed for utility-scale applications. Housed within a standard 20-ft ISO container, the PowerTitan 3.0 boasts an impressive 6.9 MWh capacity. It integrates cutting-edge battery technology with a string Power Conversion System (PCS) for flexible designs that support operation durations of 2 to 8 hours.
The standout feature of this system is the mass-produced 661Ah stacking lithium iron phosphate (LFP) cells, which offer a remarkable lifespan of 12,500 cycles. This longevity contributes significantly to the system’s cost-efficiency and reliability. Additionally, the PowerTitan 3.0 debuts the first liquid-cooled silicon carbide (SiC) PCS, achieving maximum efficiency ratings as high as 99.3% and a commendable round-trip efficiency (RTE) of 93.6% for a 4-hour duration.
Another cutting-edge feature is the five-level state of charge (SOC) balancing mechanism, which maximizes the usable capacity of the batteries. The innovative back-to-back layout reduces the system’s footprint by 21%, making it more space-efficient compared to previous iterations. The robust liquid-cooled thermal management system ensures lower auxiliary power consumption, contributing to a longer system life. Safety is paramount in the design of the PowerTitan 3.0, equipped with an 11-layer protection system and the ArcDefender technology, significantly minimizing arcing risks.
This state-of-the-art system is designed for rapid deployment and comes fully pre-tested and UL9540-certified, significantly expediting operational readiness upon delivery. Furthermore, the integration of Sungrow’s 2.0 technology allows the PowerTitan 3.0 to anticipate grid disturbances, ensuring a proactive response from the energy storage system.
PowerStack 255CS: Tailoring Energy Storage for C&I Markets
In addition to its utility-scale solutions, Sungrow has launched the PowerStack 255CS, an integrated energy storage system aimed at the North American commercial and industrial (C&I) market. Powered by 314-Ah battery cells, the PowerStack 255CS offers a compact 257 kWh capacity designed to operate efficiently within a 2-hour framework.
This all-in-one system combines an integrated PCS and Battery Management System (BMS), streamlining operations while simplifying installation complexity. The PowerStack 255CS supports multiple layout configurations, catering to varied site requirements, which enhances its versatility. The innovative design supports scalable parallel applications, permitting deployment of up to 25 units and enabling projects ranging from 257 kWh to 6.4 MWh.
Operating at three-phase, 480 volts (nominal), the PowerStack 255CS achieves exceptional efficiency, with its PCS delivering up to 98.6% maximum efficiency and an RTE of 90%. The advanced liquid-cooled thermal management system significantly reduces auxiliary power consumption by 40%, ensuring that energy demands are met more effectively.
The product meets stringent global safety standards, including UL 9540 and NFPA 855/69, having undergone over 500 tests for multi-level protection from cell to system level. This rigorous testing assures customers of its reliability and security in C&I energy storage applications.
