On June 11, Sineng stole the spotlight at the 2025 SNEC EXPO, showcasing innovative achievements, with its full-scenario grid-forming PV-storage solutions becoming the highlight of the event.
At the exhibition, Sineng unveiled its new 400kW+ string inverter. While upgrading power, the product effectively reduces equipment weight through innovative design, matching larger arrays and facilitating easier transportation and installation, thus saving investment costs for clients.
Meanwhile, the product is equipped with a newly upgraded intelligent detection system, integrating functions such as intelligent arc fault diagnosis 2.0, active air duct health detection with reverse dust removal, and AC/DC cable grounding anomaly detection, offering clients a more efficient, safer, and hassle-free user experience.
Sineng also introduced its new 2.4MW modular PV inverter, which can flexibly form 4.8MW and 9.6MW centralized PV inverter solutions, providing clients with more reliable options tailored to local conditions. The product adopts innovative zoned intelligent temperature control technology, significantly extending the lifespan of key components. Its unique modular design supports rapid replacement of individual IGBT components within 30 minutes, greatly enhancing O&M efficiency.
The product integrates microsecond-level drive recording functionality, accurately capturing and locating circulating current states during faults. Paired with an intelligent combiner box, it ensures stable equipment operation while enabling intelligent O&M management, providing reliable guarantees for the efficient operation of power plants throughout their lifecycle.
As this year’s flagship new products, the 430kW and 250kW string PCS units, equipped with “true liquid cooling” technology, control internal cabin temperature rise to less than 5K, enabling parallel tracks of reduced electricity costs and increased ROI. The 6.9MW centralized converter-booster integrated unit, configured with 1725kW centralized PCS, can match 600Ah+ large-capacity battery cells, boasting superb weather resistance to withstand harsh environments.
Sineng’s second-generation enhanced hybrid grid-forming technology has achieved comprehensive coverage across full-power-range string and centralized PCS units. Compared to traditional grid-forming technologies, Sineng has made breakthroughs in four key areas: control topology, control objects, control modes, and control parameters, significantly enhancing the active support capabilities and intelligent grid-forming levels of energy storage converters, providing reliable technical guarantees for promoting the high-quality development of new power systems and assisting grid dispatch departments in achieving full-domain grid-forming.
Against the backdrop of the accelerating global energy transition, smart home energy solutions are becoming vital carriers for achieving low-carbon lifestyles. Sineng’s exhibited solutions include 8-40kW PV inverters, 3-6kW single-phase PV-storage inverters, 5-33kW three-phase PV-storage inverters, and integrated energy storage battery solutions, meeting diverse household energy needs with outstanding adaptability and flexibility.
The products adopt a household appliance-like design with a simple and exquisite appearance, perfectly blending into home application scenarios. Additionally, equipped with the EnjoySOLAR smart energy management platform, key information such as power plant revenue can be accessed with one click. Remote OTA support ensures the power plant stays up-to-date.
The recently launched residential PV-storage solutions also made their debut at the exhibition, including integrated and split units. Built to automotive-grade safety standards, the solutions employ 335Ah high-quality, large-capacity battery cells and are equipped with a six-dimensional system. The products support the collaborative recycling of old and new batteries, with each device supporting up to four battery packs; in the split-unit solution, up to four devices can be paralleled in a single array, expanding overall capacity to up to 102.8kWh. Equipped with Sineng’s EnjoySolar energy management platform, the products can support ultra-fast switching within 10ms during grid outages or severe weather, ensuring uninterrupted power supply and becoming the ultimate guarantee for household energy security.
