30kVA Online Double-Conversion UPS Comparison for Three-Phase Critical Loads
The Xtreme Power Li90 and the Vertiv Liebert EXSV-30KTN from Vertiv are high-performance, online double-conversion UPS systems designed to protect mission-critical three-phase loads in data centers, industrial facilities, healthcare environments, and infrastructure applications.
While both systems deliver full-rated output and support ECO mode operation, the Li90 differentiates itself through higher efficiency, dramatically longer lithium battery life, a much smaller and lighter footprint, higher operating temperature tolerance, and longer warranty coverage.
For environments where installation constraints, thermal performance, and long-term lifecycle cost matter most, the Li90 delivers clear next-generation advantages.
