Sungrow could have new merchandise on show on the RE+ tradeshow, together with a second-generation modular inverter for utility-scale PV initiatives; the next-generation PowerTitan 3.0, an AC Block BESS for large-scale vitality storage functions; and the PowerStack 255CS BESS for C&I vitality storage.
4.8-MW inverter
Sungrow’s 4.8-MW SG4800UD-MV-US modular inverter for North America combines the benefits of each central and string inverters, providing 800 kW per unit in a versatile design that reduces BOS prices. The cut up modular design permits inverter module substitute in underneath an hour, minimizing downtime and maximizing operational effectivity.
The system incorporates clever fault prognosis for fast fault identification, and options self-cleaning air ducts to scale back day by day upkeep wants. Spare components administration is simplified, as a single kind of spare half is required for the inverter module. Designed for excessive sturdiness, it delivers 100% energy output in ambient temperatures as much as 45°C (113°F), and carries a sealed NEMA 4X score, making certain enhanced reliability even in harsh environments.
Security and efficiency are additional strengthened via good DC terminal temperature safety and a backside strain aid design. Moreover, its pioneering PV grid-forming and off-grid commissioning capabilities allow early business operation and enhance Return on Funding (ROI), setting a brand new benchmark for utility-scale solar energy methods in North America.
PowerTitan 3.0
For utility-scale functions, Sungrow has launched the next-generation AC block vitality storage system PowerTitan 3.0.
PowerTitan 3.0 delivers 6.9 MWh in an ordinary 20-ft ISO container, integrating batteries with the string PCS for 2- to 8-hour designs. It options the primary mass-produced 661Ah stacking LFP cell, with a 12,500-cycle lifespan for distinctive reliability and price effectivity.
The system debuts the trade’s first 430 kVA liquid-cooled SiC PCS, reaching as much as 99.3% most effectivity and as much as 93.6% round-trip effectivity (RTE) for a 4-hour length (92% together with auxiliary load).
5-level state of cost (SOC) balancing — from cell to dam — maximizes usable capability, whereas a back-to-back structure reduces footprint by 21% in comparison with the earlier technology. And strong liquid-cooled thermal administration reduces auxiliary energy use and extends system lifespan.
Security is prioritized with 11-layer safety from cell over-voltage to PCS AC fusing, and Sungrow’s ArcDefender know-how to scale back arcing dangers. The system meets all AHJ necessities in North America because of its state-of-the-art hearth security methods, and is absolutely pre-tested and authorized.
The PowerTitan 3.0 is engineered for fast deployment. The system comes absolutely UL9540-certified earlier than cargo. Enhanced on-site O&M instruments additional shorten commissioning timelines in comparison with the earlier product technology.
Embedded with Sungrow’s Stem-Cell Grid-Forming Tech 2.0, the PowerTitan 3.0 anticipates grid disturbances earlier than they escalate, making certain vitality storage responds proactively.
The product delivers renewables and vitality storage grid-forming synchronously, gigawatt-scale black begin, seamless mode switching between grid-following and grid-forming, adaptation to wide-range SCR adjustments (1-40), and permits 20 milliseconds fast response and 90° symmetrical/asymmetrical part angle leap.
With these capabilities, the product helps fast grid restoration, maximizes ancillary service income, and ensures reliability throughout all grid situations: technology, transmission, microgrids, and consumption endpoints.
As information heart demand for uninterrupted vitality soars, grid-forming storage has turn into a vital enabler. Sungrow’s PowerTitan 3.0 is engineered for this mission, providing the steadiness and reliability required for mission-critical operations.
PowerStack 255CS
Sungrow additionally introduces the PowerStack 255CS built-in vitality storage system for the North American C&I market, outfitted with 314-Ah battery cells for 257 kWh capability in a 2-hour system.
With a completely built-in PCS and BMS, PowerStack 255CS streamlines vitality storage operations whereas decreasing set up complexity. The system helps a number of structure configurations, providing adaptable deployment for various web site necessities. Moreover, pre-installed and pre-commissioned elements allow fast grid connection and improve the general deployment effectivity. Its modern design permits for scalable parallel functions, supporting as much as 25 models and initiatives between 257 kWh and 6.4 MWh, making it an excellent answer for a variety of vitality storage wants.
The all-in-one design integrates batteries and PCS in a single cupboard, working at three-phase, 480 volts (nominal). The PCS delivers as much as 98.6% most effectivity, whereas the system’s RTE reaches 90%. A sturdy liquid-cooled thermal administration system cuts auxiliary energy consumption by 40%, delivering a extra environment friendly energy provide.
The PowerStack 255CS meets world security requirements, together with UL 9540 and NFPA855/69, with multi-level safety verified via over 500 checks from cell to system degree.
