10kVA, 20kVA, 30kVA
208/120 VAC three-phase
Advanced lithium UPS designed for industrial, edge computing, and data center environments. Up to 15-year battery life and operation up to 50°C (122°F).
The Xtreme Power Li90 Series is a high-performance three-phase lithium UPS designed for applications where battery longevity, compact footprint, and reduced system weight are critical to lifecycle cost and installation success. Powered by advanced Lithium Iron Phosphate (LiFePO₄) batteries, the Li90 delivers up to 15 years of battery design life under ideal operating conditions, with reliable operation in environments up to 50 °C (122 °F).
Available in 10 kW, 20 kW, and 30 kW models, the Li90 provides unity power factor (kW = kVA) output in an ultra-slim 12.6-inch-wide cabinet, making it ideal for edge computing, industrial automation, retrofit projects, and space-constrained facilities.

Traditional three-phase UPS systems rely on large, heavy VRLA battery cabinets that increase floor space, structural requirements, and long-term maintenance costs. The Li90 replaces that approach with an integrated lithium architecture that is significantly smaller and lighter, simplifying transport, installation, and service.
With 3,000–5,000 charge/discharge cycles and a battery design life of up to 15 years under ideal conditions, the Li90 significantly reduces battery replacements over a 10–15 year system lifecycle, lowering downtime risk and total cost of ownership compared to conventional VRLA-based UPS platforms.
