Xtreme – Li90 – 20000 – 20 kVA – Three Phase Online UPS

Xtreme Power Li90 Lithium UPS — 20 kW • Three-Phase LiFePO₄

The Xtreme Power Li90 Series is a high-performance three-phase UPS platform built 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 ambient temperatures up to 50 °C (122 °F)—far beyond
traditional VRLA-based UPS designs.

Available in 20 kW model, the Li90 provides unity power factor output (kW = kVA)
in an ultra-slim 12.6-inch-wide cabinet, making it ideal for edge compute, industrial automation, retrofit projects,
and space-constrained facilities. By replacing large, heavy VRLA battery cabinets with an integrated lithium
architecture, the Li90 is significantly smaller, lighter, and easier to transport, install, and service, while also
reducing long-term maintenance costs.

Key Features & Benefits

• Up to 15-Year LiFePO₄ Battery Life — Long-life lithium batteries rated for 3,000–5,000 cycles reduce replacement events and maintenance over a 10–15 year lifecycle.
• Compact, Lightweight Cabinet — Just 12.6″ wide, delivering high power density while significantly reducing footprint and 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, dusty, or high-temperature environments.
• Advanced Communications — Supports SNMP, RS-485, USB, EPO, dry contacts, and dual communication card slots for flexible integration with monitoring and BMS platforms.

Product Snapshot

Why Choose the Li90 Lithium UPS?
