30kVA Online Double-Conversion UPS Comparison for Critical Infrastructure
The Xtreme Power Li90 and the 9355 from Eaton are both high-performance, online double-conversion UPS systems designed to protect mission-critical loads in data centers, industrial facilities, healthcare environments, and infrastructure applications.
While both systems operate in the 30kVA class and include integrated maintenance bypass, meaningful differences appear in usable power output, battery technology, efficiency, heat dissipation, footprint, runtime, temperature tolerance, and long-term lifecycle cost.
For environments where power density, thermal performance, and long-term operating efficiency matter, the Li90 delivers clear next-generation advantages.
