en.Wedoany.com Reported - On July 9, Sungrow held an "AI-Driven Computing Power New Infrastructure" AIDC new product launch event at its Hefei headquarters, unveiling its first fully self-developed SST solid-state transformer, the EnerNeo. This product utilizes digital twin technology, achieving 99.999% availability, 98.5% system efficiency, and a power density of 312kW/m², helping to reduce floor space and improve overall energy efficiency.
The EnerNeo provides a critical piece of the puzzle for Sungrow to realize a complete energy chain from renewable energy generation to computing power loads, and promotes the formation of a new ecosystem for computing-electricity synergy. Global partners including Microsoft, AWS, Alibaba Cloud, Tencent, ByteDance, Baidu, BDC, GDS, Chindata Group, Infineon, and UL participated in this launch.
The surge in computing power demand is driving a rapid increase in the power density and energy consumption of data center cabinets, accelerating the transformation of medium-voltage DC power supply architectures. High density, high fluctuation, and ultra-large loads have become the main characteristics of AIDC scenarios, posing challenges to traditional industrial frequency AC power distribution architectures in terms of IT floor space, efficiency, and commissioning cycles. The SST-based 800V DC power supply architecture, with advantages such as space savings from direct medium-voltage connection, improved efficiency through single-stage conversion, and agile delivery via integrated design, has become the industry-recognized solution. Sungrow's EnerNeo is a product integrating power supply and distribution, tailored for the needs of AIDC scenarios.
This product features a flexible granularity design, supporting free combination from 1.5MW to 4.5MW, adaptable to different construction phases, various data center architectures (such as distributed, 2N, and DR), and different power density requirements, meeting diverse application scenarios including phased expansion, retrofitting of existing facilities, and new high-performance computing nodes. Based on digital twin technology with high-precision electromagnetic models, it enables complete station-level full-domain simulation, supporting rapid solution design and simulation verification.
In terms of intelligence, the EnerNeo possesses closed-loop protection capabilities from warning to monitoring to localization, including pulse current partial discharge detection, early warning of insulation faults, prediction of critical component failures and health status monitoring, as well as fault waveform recording at the second level and root cause localization. Regarding reliability, the product adopts a unique industry design featuring "medium/low voltage zoning + quick plug-in" modules. The modules utilize a 6+3 redundant architecture, doubling the mean time between failures, and support system under-saturated operation, achieving the industry's highest system availability of 99.999%. The entire unit achieves zero partial discharge at the cabinet level, and the intelligent module rotation design increases the overall equipment lifespan by 20%. The quick plug-in design of the medium-voltage module limits maintenance time to no more than 15 minutes, while the low-voltage modules support online hot-swapping for zero-downtime maintenance. Each low-voltage module weighs 11kg, enabling single-person maintenance.
The safety design of the EnerNeo begins with risk isolation from the design phase, employing system-level physical isolation to protect insulation safety. A directional explosion vent is installed on top of the input cabinet to ensure personnel safety, and the three-phase inter-phase cabinet isolation of the power cabinet eliminates the risk of internal arcing. The power modules utilize an H-bridge cascaded topology circuit, offering intrinsic safety, with triple optimization in components, circuitry, and protection. The high-frequency transformer uses a vacuum insulation design to enhance reliability.
In terms of commercialization, Sungrow signed strategic cooperation and framework procurement agreements with Guangdong HEC Technology Holding Co., Ltd. ("HEC") and China United Data Group ("China United Data") respectively at the launch event. Additionally, Sungrow and Alibaba Cloud Intelligence Computing Group jointly inaugurated the "Green Token Joint Innovation Center," further refining its AIDC ecosystem cooperation framework.
Addressing the evolution direction of AIDC towards large clusters, prefabrication, and medium-voltage minimalist links, Sungrow has planned a complete long-term product iteration roadmap. Subsequent releases will include UL-certified models, native outdoor models, and 35kV SST products, matching the high-density, diverse power supply needs of global leading computing power customers. AIDC is the debut scenario for Sungrow's SST products, but not the endpoint of their application. The company plans to sequentially launch SST products for scenarios such as ultra-fast charging, cascaded energy storage, photovoltaics, wind power, hydrogen energy, and power grids from 2027 to 2030.
Sungrow's layout for SST solid-state transformers began in 2015. In 2018, it successfully developed the world's first 35kV/1500V, 6MW photovoltaic direct-connected SST and completed grid-connected validation. Subsequently, it expanded this technology to scenarios such as direct-connected energy storage and multi-port charging. Zhang Di, President of Sungrow's AIDC Power Supply Division, stated that the company is committed to leveraging its advantages in green power direct connection and energy storage synergy, integrating global manufacturing capacity, agile delivery capabilities, and full lifecycle operation and maintenance services to respond to the core demands of high-density computing scenarios from source to chip.
