Li90 UPS comparisons
The Xtreme Power Li90 Series is an integrated three-phase lithium online double-conversion UPS platform for infrastructure modernization, replacement of aging systems, and long-term lifecycle optimization. It is commonly evaluated against Eaton, Vertiv, and APC platforms when upgrading legacy infrastructure or standardizing new enterprise deployments.
The facility-level platform in the lithium portfolio
Li90 is the integrated lithium three-phase UPS for facility-level infrastructure — typically selected for modernization projects where lifecycle-cost reduction, reduced maintenance, and long-term performance are priorities. Other Xtreme Power lithium platforms serve rack-level deployments.
Platform first, then model
This hub includes both platform-level and model-level comparisons. Platform comparisons evaluate modernization strategy and system architecture; model comparisons focus on capacity alignment and replacement planning. Most evaluations begin with platform selection, then sizing against existing infrastructure.
Start with the platform comparison
Platform comparisons evaluate architecture, topology, battery chemistry, footprint, maintenance exposure, and modernization strategy against each competing brand. Start here to determine the best-fit platform before selecting a capacity.
Then review model-level comparisons
Model comparisons focus on a specific capacity (10, 20, 30 kVA), runtime alignment, and replacement planning against a competing model at the same rating. Use these to validate the Li90 against a specific system you are replacing.
Li90 vs competing three-phase UPS platforms
Enterprise projects frequently involve replacing aging infrastructure alongside evaluating modern platforms. Each platform comparison covers architecture, topology, battery chemistry, footprint, and modernization positioning against one competing brand.

|---|---|---|---|---|
| 10 kVA | vs 93PM 10 kVA → | vs 9355 10 kVA → | — | vs Galaxy VS → |
| 20 kVA | vs 93PM 20 kVA → | vs 9355 20 kVA → | vs EXS-V 20 kVA → | vs Galaxy VS → |

Engineered for lifecycle predictability
Integrated LiFePO₄
Lithium iron phosphate energy storage is built into the cabinet — no external battery cabinets, reducing footprint, installation complexity, and maintenance exposure.
Online double-conversion
Continuous, fully conditioned output with integrated maintenance bypass for safe on-site service — unity power factor delivers full usable capacity (kVA = kW).
Compact single cabinet
High power density in a slim 12.6-inch-wide cabinet — suited to electrical-room modernization without expanding footprint.
Reduced service exposure
Long-life LiFePO₄ removes the periodic battery-replacement cycle of VRLA systems, lowering both planned and unplanned maintenance events.
Thermal & placement flexibility
Improved thermal performance and hot-swappable modules support flexible placement in edge, automation, and retrofit installations.
Predictable lifecycle cost
Long service life and minimized intervention give long-term cost stability and align UPS infrastructure with facility-planning cycles.
Lithium for infrastructure modernization
Many enterprise UPS projects are driven by replacing aging VRLA-based systems. Lithium platforms enable extended battery service life, reduced maintenance intervention, improved infrastructure density, and more predictable lifecycle cost — while maintaining the existing electrical architecture. The Li90 supports modernization that improves lifecycle performance and operational efficiency without major upstream changes.
