10 kW, 20 kW, 30 kW | 208/120 VAC Three-Phase
Long-Life, Compact, Lightweight Lithium UPS for Critical Three-Phase Applications
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 life and 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.

Compact Footprint and Lightweight Architecture with Industry-Leading Battery Life
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 15-year battery design life, the Li90 reduces battery replacements over a 10–15 year lifecycle, lowering downtime risk and total cost of ownership compared to conventional VRLA-based UPS platforms.
Key Features & Benefits
- Up to 15-Year LiFePO₄ Battery Life
Long-life lithium batteries rated for 3,000–5,000 cycles reduce replacements and maintenance over the system lifecycle. - Compact, Lightweight Cabinet
Just 12.6 inches wide, the Li90 delivers high power density while reducing footprint and system weight compared to traditional three-phase UPS systems. - High-Temperature Operation
Designed to operate safely up to 50 °C (122 °F), ideal for industrial, edge, and non-conditioned environments. - Unity Power Factor Output (1.0 PF)
Delivers full usable kW capacity without derating for high-density loads. - Hot-Swappable Lithium Battery Modules
Battery modules can be replaced without powering down the UPS or connected equipment. - Integrated Maintenance Bypass
Enables safe on-site service while keeping critical loads powered. - Rugged Industrial Design
Conformal-coated PCBs and a smart de-dust cooling system enhance reliability in harsh environments. - Advanced Communications
Supports SNMP, RS-485, USB, EPO, dry contacts, and dual communication card slots.
