Facility-scale modular, N+1

The M90U is XPC's facility modular platform (15 to 140 kW at 208/120V with modular N+1 redundancy) built from hot-swappable 15/20 kW power and battery modules behind a full wrap-around maintenance bypass. XPC cites a footprint that saves up to 40% of floorspace versus comparable systems. Four variants cover the range: M90U (15 to 60 kW, internal battery), M90LU (external battery, extended runtime), M90U-80 (to 80 kW in one cabinet) and M90U-140 (to 140 kW with the M90-BC enclosure).

A modern replacement for an aging centralized UPS

If you're running a legacy fixed-capacity centralized UPS that's aging or near end of life (say an APC Symmetra, an Eaton BladeUPS or a Vertiv Liebert EXM) the M90U is built to take its place: instead of swapping one monolithic box for another, you move to a platform you scale a module at a time, with N+1 redundancy and per-module serviceability. Tell us the unit you're replacing and your load, and we'll size, supply and install the M90U to match.

Batteries and battery cabinets for the XPC M90U

Battery strings and cabinets depend on the configuration and runtime. Batteries for Xtreme Power UPS cabinets are matched by string voltage and block size.
