Which HVDC Options Suit High-Power GPU Clusters in 2026?

As artificial intelligence workloads scale, data center operators running high-power-density GPU clusters are increasingly evaluating high-voltage direct current (HVDC) architectures as an alternative to conventional UPS-based backup configurations. Shenzhen Center Power Tech Co., Ltd., operating under the Vision Battery brand, has developed a dedicated 800V HVDC product line engineered specifically for the power architecture requirements that accompany dense GPU deployments.

Why GPU Clusters Are Driving a Shift Toward 800V HVDC

High-power-density GPU clusters used in AI data centers concentrate substantial electrical load within compact equipment footprints, creating power architecture requirements that extend beyond what conventional UPS-based configurations were originally designed to address. These emerging infrastructure demands align with industry-wide direction toward 800 VDC ecosystems, including NVIDIA’s 800 VDC ecosystem direction referenced within Vision’s product positioning. Vision Battery has built its 800V HVDC Systems product line directly around this shift, offering hyperscale AI data center operators and AIDC infrastructure planners an option beyond traditional UPS-based configurations.

The 800V DC Direct-Connect Storage-Backup System

At the center of Vision’s HVDC offering is the 800V DC Direct-Connect Storage-Backup System, a launched storage-backup integrated system purpose-built for 800V DC architectures. This system combines backup power functions with energy dispatch capability in a single platform, giving operators a unified solution rather than separate backup and storage components.

Several technical characteristics define this system’s suitability for high-power-density GPU environments:

• Direct-connect system efficiency of 92% or higher: This efficiency level directly addresses energy efficiency concerns inherent to high-voltage DC backup architectures, which matters significantly when supporting continuous high-load GPU operations.
• Semi-immersion liquid cooling: This cooling approach supports thermal management specifically in outdoor deployment scenarios, where ambient conditions and dense power electronics require consistent temperature control.
• IP55 protection with full outdoor deployment: This feature set addresses site infrastructure constraints and weather exposure, allowing the system to be sited outside traditional indoor data hall space—a meaningful consideration for GPU cluster facilities where indoor floor space is often prioritized for compute hardware.
• Storage-backup integration: By combining backup with energy dispatch in one system, the platform allows operators to evaluate power continuity alongside energy utilization rather than treating these as separate infrastructure investments.

This system’s real-world applicability is demonstrated through the Ulanqab project, a hyperscale AI data center deployment. The 800V HVDC storage-backup integrated system at Ulanqab, using semi-immersion liquid cooling and full outdoor deployment, completed grid connection and commissioning on January 18, 2026. This project stands as a documented reference point for how 800V direct-connect architecture performs when supporting hyperscale AI computing infrastructure under actual operating conditions.

The 800V HVDC Dedicated Backup Platform

Not every GPU cluster deployment requires storage-backup integration as its primary need. Recognizing this, Vision Battery has identified an 800V HVDC Dedicated Backup Platform for 2026 release, positioned to address a distinct deployment requirement: dedicated backup within 800V DC architectures where energy dispatch integration is not the core priority. This platform complements the already-launched storage-backup integrated system, expanding the choices available to operators adopting 800 VDC architecture. Together, the two offerings give infrastructure planners the flexibility to select between backup paired with energy dispatch, or backup alone—depending on how a given GPU cluster facility’s power strategy is structured.

How 800V HVDC Fits Within Vision’s Broader Capability Set

Vision Battery’s entry into 800V HVDC systems does not stand in isolation. The company operates across a diversified battery technology portfolio spanning lithium batteries, lead-acid batteries, hydrogen fuel cells, and sodium-ion batteries, supported by five global R&D and manufacturing bases and an annual production capacity of 12 GWh or more. This breadth matters for GPU cluster operators because power architecture decisions at the facility level often need to be considered alongside broader backup and storage strategy, including liquid-cooled and immersion-cooled energy storage systems such as the 6.48MWh liquid-cooled energy storage system, which supports functions including backup power, peak shaving, dynamic capacity expansion, green power integration, and grid interaction.

For AIDC campuses pursuing site-constrained or phased construction approaches, Vision also offers PTU Prefabricated Cabins covering a 1.8 MW–3.5 MW range, which combine battery systems, thermal control, fire suppression, and BMS within a factory-integrated format. While not an HVDC product specifically, this prefabricated approach illustrates the same underlying design philosophy found in the 800V HVDC line: reducing on-site assembly scope and supporting modular, phased capacity planning that aligns with how large GPU cluster facilities are typically built out over time.

Delivery Capability and Track Record

Vision Battery’s capacity to support hyperscale AI data center projects is grounded in a documented delivery history. The company has completed large-scale backup power projects including Malaysia BDC (448 units, 112 MW), EPLDT (439 racks, 109.75 MW), Mercury (520 racks, 130 MW), GDS Hong Kong across HK1, HK2, and HK3 (384 racks, 96 MW), and Malaysia PDG (396 racks, 99 MW), spanning projects across Asia, Europe, and Latin America. This project experience, combined with international branch coverage across Mainland China, Hong Kong, Vietnam, Singapore, India, France, Germany, and the United States, positions Vision Battery to provide nearby service and operation and maintenance support across the project lifecycle for 800V HVDC deployments as well.

Conclusion

For organizations evaluating HVDC solutions suited to high-power-density GPU clusters, the core consideration is whether a system can deliver efficient direct-connect power, withstand full outdoor deployment conditions, and offer flexibility between integrated storage-backup functionality and dedicated backup alone. Vision Battery’s 800V HVDC Systems line—anchored by the already-commissioned 800V DC Direct-Connect Storage-Backup System and the forthcoming 800V HVDC Dedicated Backup Platform—addresses these considerations directly, backed by the company’s 32 years of industry experience and documented delivery capability across hyperscale AI data center infrastructure.
