At SNEC 2025, which will take place in Shanghai from June 11 to 13, Sungrow, the world’s top producer of PV inverters and energy storage systems, will showcase its extensive renewable energy portfolio. Highlights include the PowerTitan 3.0 Energy Storage System (ESS) platform, the next-generation 1+X 2.0 Modular Inverter for utility-scale PV projects, state-of-the-art grid-forming technologies, EV charging solutions, and a wide variety of distributed generating offers.
1+X 2.0 Modular Inverter: Driving Utility-Scale Solar’s Future
Sungrow introduced their newest 1+X 2.0 Modular Inverter, which is aimed at the utility-scale market. This inverter, which won the iF Design Award, offers more adaptability with scalable block designs that range from 800kW to 9.6MW. The product’s split modular design allows for rapid field replacement by isolating crucial parts (capacitors, IGBTs) in the upper inverter module. Field engineers can quickly change modules thanks to the simplified operation and maintenance (O&M) process, which cuts down on time to one hour per module swap.
The new inverter offers exceptional dependability, consistent operation without derating at temperatures as high as 45°C, and IP66 protection. In order to fulfill the industry’s exacting demands for performance, availability, and dependability, it also integrates AI-driven fault detection, AI-enhanced DC-side safety management, and improved grid-forming capabilities.
PowerTitan 3.0 ESS Platform: Setting a New Benchmark for Utility-Scale ESS
Sungrow’s PowerTitan 3.0 sets a new benchmark for utility-scale energy storage through unmatched flexibility, energy density, and intelligence.
Offered in 10ft Flex (3.45MWh), 20ft Class (6.9MWh), and 30ft Plus (12.5MWh) versions, it supports durations from 2 to 12 hours and operates reliably in extreme conditions. The flagship 30ft Plus version is the world’s largest BESS in both capacity and power density, featuring 684Ah stacking battery cells and delivering up to 12.5MW/50MWh per block, achieving over 500kWh per square meter in power density.
In addition, the PowerTitan 3.0 adopts all-in-one AC-DC block design architecture, its power density accounts for both the battery system and the power conversion system (PCS). Excluding the PCS, the battery alone achieves an impressive energy density of 570kWh per square meter. This high integration helps reducing land footprint by 45% and cabling by 10%, significantly lowering CAPEX for customers.
In terms of energy efficiency, with an all-in-one AC-DC block design, stacking battery cell, and liquid-cooled silicon carbide (SiC) PCS, the platform achieves an industry-leading round-trip efficiency (RTE) of 93.5%.
From a safety perspective, as system capacity scales up and long-duration energy storage advances, the risks associated with parasitic balancing currents and short-circuit currents increase significantly. The PowerTitan 3.0 integrates standard short cables within the liquid-cooled container, enabling DC cables stay inside the container. This effectively eliminates the risk of DC-side short circuits while also addressing the issue of parasitic balancing currents between clusters, further reinforcing its safety advantages.
C&I Solutions: Empowering Every Business
As industrial and commercial users strive to cut emissions and control energy costs, Sungrow’s C&I energy solutions offer reliable and scalable clean energy.
Among the highlights is Sungrow’s latest C&I liquid-cooled ESS, the PowerStack 255CS. Equipped with advanced 314Ah battery cells, it offers flexible power capacities—257kWh (2-hour system) or 514kWh (4-hour system)—along with over 90% round-trip efficiency and a 20-year design life. Fully integrated with PCS, EMS, and BMS, and certified under stringent global safety standards such as UL9540 and NFPA855/69/68/14, the system ensures seamless operation across a wide range of scenarios, including C&I standalone ESS, PV plus ESS, EV chargers plus ESS, and microgrids.
Also on display is the SH125CX, a powerful 125kW hybrid inverter. Combined with PowerStack 255CS, it forms a fully DC-coupled solution ideal for medium and large-scale C&I projects.
Additional smart devices such as power optimizers and rapid shutdown units further enhance energy yields and safety—optimizing every kilowatt and maximizing return on investment.
Residential Solutions Offers Greater Independence, Reliability, and Efficiency
As the region experiences rapid urbanization and rising energy costs, there is a clear shift toward residential solar-plus-storage solutions that offer greater independence, reliability, and efficiency. Sungrow’s residential portfolio is designed in response to these needs, setting a new benchmark for intelligent and user-centric home energy management.
A highlight is the upcoming residential low-voltage ESS solution MG5/6/8/10RL hybrid inverter series (up to 10kW), combined with the MGL060 battery (6kWh each). This next-generation solution is flexible, robust, user-friendly, and fully optimized for home energy needs, with the official launch coming soon.
Sungrow also presents its full lineup of microinverters (450W–2,000W), designed for various residential applications such as balconies and rooftops. With more power generation, plug-and-play functionality, and one-click network configuration, Sungrow provides users with a more efficient and convenient experience.
In addition to its solar and storage solutions, Sungrow also showcased its EV charging portfolio, featuring the 480kW ultra-fast charger with advanced isolated air-cooling technology, and the 7kW AC charger designed to meet the needs of both commercial and residential users.
