Medium-voltage to 800 VDC conversion stage now operating under load; joint white paper offered as a technology-neutral framework for industry evaluation

Highlights

• The three-phase medium-voltage to 800 VDC conversion stage of SolarEdge’s DC powertrain is now operating under load in the company’s engineering laboratories, with system-level validation of the full path underway.
• SolarEdge is publishing a protection and grounding framework for 800 VDC systems, developed with NVIDIA and offered for industry evaluation. It is technology-neutral and implementable by any vendor, so operators, suppliers and standards bodies can work to common functions and testable outcomes.
• The white paper, “800 VDC Protection and Grounding for AI Data Centers,” is available here

MILPITAS, Calif. – September 10, 2026 – SolarEdge today announced that the medium-voltage to 800 VDC conversion stage of its DC powertrain for AI data centers is now operating under load. Alongside this milestone, the company published a protection and grounding framework for 800 VDC systems, developed with NVIDIA, that sets out the functions, evidence and validation needed for safe, reliable 800 VDC deployment.

As the industry moves toward 800 VDC distribution, many protection practices developed for AC environments do not transfer to converter-fed DC architectures. To set out what is needed, SolarEdge and NVIDIA today published the joint white paper “800 VDC Protection and Grounding for AI Data Centers.” Building on NVIDIA 800 VDC architecture work, the paper separates common protection and grounding requirements from the design choices of any one implementation, evaluates grounding options and the criteria for selecting the grounding impedance, and describes a zone-based protection approach: fault location with continuous operation in the restricted facility zone, and immediate interruption at the rack interface where personnel work.

NVIDIA supports an open, multi-vendor 800 VDC ecosystem and encourages multiple conversion topologies, grounding configuration or protection technology. The SolarEdge architecture presented in the paper is one candidate implementation, offered to advance engineering discussion and validation. High-resistance midpoint grounding, solid-state transformers and solid-state circuit breakers are candidate approaches rather than universal requirements.

“The transition to 800 VDC will ultimately depend on whether these systems can be protected, serviced and trusted at scale,” said Shuki Nir, Chief Executive Officer of SolarEdge. “That will require collaboration across the ecosystem. We are building the full DC path from utility to rack, and we worked with NVIDIA on this paper to advance the protection and grounding considerations the whole industry needs.”

The functions that underpin 800 VDC protection, including series arc detection, DC disconnection and insulation monitoring, have been running in SolarEdge photovoltaic products for well over a decade. That record is component precedent. It is not data center validation. SolarEdge is developing a data center platform comprising a medium-voltage solid-state transformer, DC distribution with per-branch residual current measurement and solid-state interruption, insulation monitoring, and system-level monitoring. These AI data center products are under development and validation, and are not yet generally available.

SolarEdge welcomes independent technical evaluation and invites operators, vendors and standards bodies to test and challenge the framework. The white paper is available for download here. Further information on SolarEdge’s 800 VDC platform is available here.
