Vertiv launches outdoor medium-voltage UPS to get AI data centers on the grid faster

Nov 12, 2026
The PowerNexus MV UPS sits outside at the grid connection, smooths AI load swings and, with batteries, can back up a site for up to four hours. Shipments start mid-2027.

Vertiv has introduced the PowerNexus MV UPS, a medium-voltage power protection system for colocation, neocloud and hyperscale AI data centers, according to a press release. It is built for outdoor installation at the point where a site connects to the utility, which frees indoor floor space for compute. Shipments are expected to begin in mid-2027.

The system is designed to ride through grid faults and absorb rapid swings in AI load before they reach the grid. Paired with long-duration batteries, it can back up a site for up to four hours, which Vertiv says reduces reliance on diesel generators. It runs at up to 98.5% efficiency at peak.

"Data centers are facing new infrastructure challenges, including grid queues that can delay deployment and revenue generation," said Kyle Keeper, who leads Vertiv's power management business. Vertiv also plans a dedicated medium-voltage lab at its power research center in Bologna, Italy.
