Three-Phase Lithium UPS Comparison · 10–30 kVA

Li90 vs Eaton 93PM

Engineers modernizing facility power in the 10–30 kVA three-phase class compare the Xtreme Power Li90 with the Eaton 93PM when defining lifecycle-cost strategy, electrical-room deployment, and modernization pathways. Both are online double-conversion platforms, and both now offer lithium battery options — so the meaningful differences are architectural: how lithium is integrated, footprint, thermal tolerance, and standard-versus-optional configuration.

Key differentiators

Where the platforms genuinely diverge

The Eaton 93PM is a widely deployed, vertically scalable three-phase platform compatible with lithium-ion (including LFP) as well as VRLA. The Li90 differs less on whether lithium is available, and more on how it is delivered.

  • Integrated in-cabinet lithium as standard, vs the 93PM’s separate or integrated battery cabinet
  • Standardized LiFePO₄ (LFP) across all ratings, vs configurable lithium-ion options
  • A single 12.6-inch cabinet for UPS and batteries, vs a UPS-plus-battery-cabinet footprint
  • System-level 50 °C rating, vs ~40 °C typical (higher with the 93PM lithium option)
  • No planned battery-replacement event, vs a chemistry-dependent lifecycle
  • Factory-backed modernization architecture, vs Eaton’s established global service network

Choosing between them

Across healthcare imaging, industrial automation, commercial-building modernization, distributed mission-critical, and enterprise-edge deployments, organizations modernizing legacy VRLA-based three-phase UPS evaluate lithium-integrated platforms to improve lifecycle-cost performance, simplify maintenance planning, and optimize electrical-room utilization. The Li90 aligns with strategies prioritizing long-term infrastructure predictability and a single-cabinet footprint; the 93PM suits vertically scalable growth and Eaton-standardized service.

Choose the Li90 if you need

  • Integrated lithium (LFP) as standard, inside one cabinet
  • The densest electrical-room footprint — a single 12.6-inch cabinet
  • A system-level 50 °C rating
  • Predictable LFP lifecycle with no planned battery-replacement event
  • Retrofit modernization of legacy VRLA three-phase infrastructure

Consider the Eaton 93PM if you need

  • A vertically scalable platform for future capacity growth
  • Standardization on Eaton’s established global service ecosystem
  • Flexibility across VRLA and multiple lithium-ion options and configurations
  • Integration into an existing Eaton power infrastructure
