What Vertiv announced
Vertiv Holdings Co. introduced the Vertiv PowerNexus MV UPS, an outdoor-rated medium-voltage power system aimed at colocation, neocloud and hyperscale data center operators, the company said. It is designed to be deployed outdoors at the point of connection, combining a medium-voltage UPS, fault ride-through and AI power smoothing on one platform. Vertiv said it is engaging customers globally and expects shipments to begin in mid-2027.
The numbers Vertiv cites
The system is rated at up to 98.5% peak operating efficiency, achieved through a line-interactive topology, according to the company. Paired with long-duration battery systems, it can provide battery-backed operation of up to four hours, which Vertiv says can reduce reliance on diesel generators. The company also said the outdoor skid frees indoor space for compute, and that a Power Systems Computer Aided Design model is available so customers can simulate grid interactions before deployment.
Demonstrations and test results
Vertiv said it held proof-of-concept demonstrations with QTS, SoftBank and Rosendin at its Global Power R&D and Customer Experience Center in Bologna, Italy. Testing showed stable performance across 0–100% 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. QTS facilities operations senior vice president Ryan Kuithe said the system maintained stable power through dynamic load changes and voltage disturbances.
The Bologna laboratory
Vertiv said a dedicated Medium Voltage Laboratory at the same Bologna facility is scheduled to become operational in 2027. It is intended for research and development, full-voltage validation, customer demonstrations, service training and system-level testing for medium-voltage architectures including MV UPS, MV to 800 VDC and battery energy storage. Giovanni Zanei, vice president of large power conversion at Vertiv, said the facility will help customers evaluate new architectures, including 800 VDC, with greater confidence.
