Sunwoda Banks On 800 V HVDC Platform For AIDC

The company has added an 800 V HVDC power distribution platform and cabinet-based lithium-ion batteries for storage and short-duration backup to its product portfolio

  • Sunwoda’s 6C series batteries are designed to provide emergency backup for up to 10 minutes, while the 10C ensures uninterrupted operation for up to 5 minutes, in AI scenarios 

  • Its HVDC platform is engineered to support SST busbar, converting medium-voltage AC to 800 V DC 

  • These products are expected to be promoted during the 2026 Washington Data Center World event 

Sunwoda, an energy conversion system provider, launched its AI data center (AIDC) 800 V product matrix for high-density and demanding AI workloads.  

In most data centers today, grid power arrives as AC before being stepped down and converted to DC several times along the distribution chain. AI server clusters, particularly racks (4-8 kW) built around GPUs, consume a consistent high level of power. Its repeated AC-DC conversions reduce overall efficiency and increase thermal load. In comparison, 800 V DC-based designs, which are now gaining traction in high-density megawatt-scale AI installations, distribute DC throughout the power system up to DC busbars of data centers, minimizing conversion stages and reducing power losses. The company further explained that compared with 400 V AC-based decentralized power distribution, its higher DC system voltage lowers current for the same power output. Hence, it reduces resistive losses and can simplify power distribution across large facilities. 

Over the next 3 to 5 years, the AIDC industry will adopt 800 V high-voltage direct current (HVDC) power deployment, converting 380 V AC to 800 V DC. Beyond 5 years, the adoption of solid-state transformers (SST) between incoming medium-voltage (10-35 kV) and 800 V SST DC busbar will be common, claims Sunwoda.  

Against this backdrop, the company launched its 6C and 10C cabinet-based lithium-ion batteries, providing energy storage and short-duration backup for multiple cycles in AI scenarios. 

The former, with a capacity of up to 386 kW, is designed for an emergency backup of up to 10 minutes, while the latter (760 kW) supports only 5 minutes of backup. In addition to these batteries, the latest product portfolio comprises an 800 V HVDC platform, compatible with the SST busbar.  

Sunwoda also announced plans to showcase its latest products at the 2026 Washington Data Center World event.
