Vertiv Holdings Co. filed an 8-K on November 12, 2026, disclosing the introduction of the Vertiv PowerNexus MV UPS, an outdoor-rated medium-voltage uninterruptible power system targeting colocation, neocloud, and hyperscale data center operators.

Key Highlights

  • New product announced: The Vertiv PowerNexus MV UPS combines medium-voltage UPS, fault ride-through, and AI power smoothing in a single outdoor platform.
  • Shipment timeline: According to the filing, shipments are expected to begin in mid-2027.
  • Peak efficiency: The system delivers up to 98.5% peak operating efficiency, the company disclosed.
  • Battery backup duration: When integrated with long-duration battery systems, the solution can provide battery-backed operation of up to four hours, per the filing.
  • Proof-of-concept participants: Demonstrations were hosted with QTS, SoftBank, and Rosendin at Vertiv's Global Power R&D and Customer Experience Center in Bologna, Italy.
  • New laboratory planned: A dedicated Medium Voltage Laboratory at the Bologna facility is scheduled to become operational in 2027.
  • Voltage disturbance testing: Testing included ride-through of a 100% voltage sag for 150 milliseconds and 25% overvoltage for five seconds, according to the filing.

Vertiv PowerNexus MV UPS: Capabilities and Customer Validation

According to the filing, Vertiv Holdings Co. (NYSE:VRT) introduced the Vertiv PowerNexus MV UPS on November 11, 2026. The company described the product as designed to help data center operators accelerate utility interconnection, optimize site utilization, and support evolving grid requirements. The system is designed for outdoor deployment at the utility connection point, moving critical power infrastructure outside the data hall to preserve indoor space for compute equipment.

The filing states that the solution delivers Class 1 output voltage quality in accordance with IEC 62040-3, designed to protect critical loads during grid disturbances and upstream faults. Its line-interactive topology is reported to achieve up to 98.5% efficiency under peak conditions. The company also noted that a Power Systems Computer Aided Design (PSCAD) model is available to help customers simulate system behavior and validate integration before deployment.

Vertiv disclosed that proof-of-concept demonstrations were recently conducted with QTS, SoftBank, and Rosendin at its Global Power R&D and Customer Experience Center in Bologna, Italy. Testing demonstrated, according to the filing, stable performance across 0 to 100% loads, Class 1 voltage accuracy during rapid load changes, and ride-through of a 100% voltage sag for 150 milliseconds and 25% overvoltage for five seconds. Additionally, the company disclosed plans for a dedicated Medium Voltage Laboratory at the Bologna facility, scheduled to become operational in 2027, to support research, full-voltage validation, customer demonstrations, and system-level testing for medium-voltage architectures including MV UPS, MV to 800 VDC, and battery energy storage technologies. The filing noted that this release contains forward-looking statements subject to the company's cautionary language and risk factors described in its regulatory filings.
