Specifications
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-80
Battery strings and cabinets depend on the configuration and runtime. A worn string in the XPC M90U-80 can be rebuilt from the UPS battery block catalogue.
