Product Q&A

Q:Is SST a replacement for UPS?

Yes, for DC-bus architectures. SST + HVDC shelf can replace transformer + UPS + PDU in many AIDC designs. For AC-critical loads,SST can work parallel with UPS as 10kV medium-voltage UPS (SST + flywheel).

Q:What output voltage do I need for AI racks?

Most GPU clusters (H100/B200) run 800V DC bus or 400V DC (+-400V). SST supports 200-1000V configurable per cabinet.

Q:Can SST integrate with solar / storage?

Yes. SST supports AC + DC dual input, four-quadrant operation - can couple PV (DC-side) and ESS directly, avoiding extra inversion loss.

Q:What's the lead time?

Standard 840-1680kVA: 8-12 weeks. Prefabricated skid shortens on-site work to ~24h commissioning.

Q:Is Delta authorization required to purchase?

Yes. SST is a Delta premium infrastructure product. We are Delta authorized partner -contact us with your project location for quotation.
