Delta debuts prefabricated SST-based DC power system for AI data centers
Delta has unveiled a prefabricated DC power system built around a solid-state transformer (SST) at Energy Taiwan 2026. According to the company, the modular design cuts on-site deployment time by up to 50% for AI factories and high-density computing sites.
- Delta debuted a prefabricated SST-based DC power system at Energy Taiwan 2026 for AI factories and HPC data centers.
- According to Delta, the modular design shortens on-site deployment time by up to 50%.
- Delta says its SSTs reach up to 98.5% efficiency and can improve grid-to-chip efficiency by up to 4, 5% in AI data centers.
- Delta and The Great Taipei Gas Corporation are developing Taiwan's first 550 kW SOFC demonstration site with locally made equipment.
- Delta plans to begin SOFC trial production by the end of 2026.
A containerized SST system for AI infrastructure
Delta, which describes itself as a global leader in power management and smart green solutions, is presenting its latest microgrid offerings under the theme "Resilient Energy, Powering the AI Future." The centerpiece is a prefabricated DC power system that combines a containerized SST with DC/DC converters and control equipment. The aim is to reduce the number of power conversion stages in key applications.
The system is designed for AI factories and HPC data centers. According to Delta, its in-house SSTs reach an energy efficiency of up to 98.5%, and the system can improve efficiency from grid to chip by up to 4, 5% in AI data centers. Depending on site requirements, it can also include a high C-rate battery that responds quickly to AI load fluctuations, providing millisecond-level power support to keep delivery to the loads stable.
Because the design is modular and prefabricated, less wiring, installation and commissioning work is needed on site. Delta says this helps customers speed up AI infrastructure deployment while leaving room for future capacity expansion.
SOFC on-site generation and a Taiwan demonstration site
Delta is also showing on-site power generation based on solid oxide fuel cells (SOFC), along with energy storage and intelligent dispatch with off-grid operation capabilities. The company says its SOFC solution provides stable, low-carbon power and can be linked with the utility grid, storage systems and other energy resources, reducing reliance on a single source.
SOFC generates electricity through an electrochemical process. With heat recovery, Delta states that an SOFC system can reach an overall energy efficiency of up to 85%. The company points to AI data centers, manufacturing facilities and critical infrastructure that run around the clock as target uses. Delta plans to begin trial production by the end of 2026.
Patrick Zhao, Vice President and General Manager of Delta's Energy Infrastructure Business Group, said Delta recently partnered with The Great Taipei Gas Corporation to develop Taiwan's first 550 kW SOFC demonstration site using locally manufactured equipment. He said microgrids integrate grid power, on-site generation, energy storage and loads "to match supply with demand in real time."
Expert talks, EnergiQ and show details
At its booth, Delta will host presentations by speakers from the Industrial Technology Research Institute's (ITRI) Green Energy and Environment Research Laboratories, the Taiwan Institute of Economic Research (TIER), and its own smart energy and microgrid experts.
The program includes EnergiQ from Delta's ESG Consulting Office. It is a digital platform paired with energy-saving consulting services and designed to comply with the ISO 50001 energy management methodology. Delta says it covers identification of high-consumption equipment and systems, EnPI setting and tracking, energy baseline establishment, efficiency project monitoring and performance tracking, to help enterprises build a comprehensive energy management process.
Delta is exhibiting at Taipei Nangang Exhibition Center Hall 1, 4F (Booth M0319a) from October 14 to 16.
What it means for AI data center operators
Zhao said the rapid expansion of AI computing is "redefining enterprise requirements for energy infrastructure." Delta's pitch is that fewer conversion stages, faster prefabricated deployment and on-site generation can help operators gain greater energy autonomy, resilience and efficiency. The efficiency and deployment figures are the company's own claims, and the source does not give pricing or availability for the SST-based system.
