The Xtreme Power Li90 20 kVA is a compact three-phase lithium UPS designed for electrical rooms, telecom infrastructure, and facility systems requiring higher-capacity power protection in space-constrained environments. The system delivers full 20 kW three-phase power with integrated LiFePO₄ batteries and up to 22 minutes of internal runtime in a slim, lightweight cabinet that eliminates external battery cabinets and simplifies deployment.
Part of the Li90 3-phase lithium UPS platform and engineered for high-density installations, the 20 kVA model supports scalable internal runtime of 15 or 22 minutes using modular battery blocks while maintaining a compact footprint. This architecture enables deployment in locations where conventional 20 kVA UPS systems require large external VRLA battery frames to achieve similar runtime.

Compact 20 kVA 3-Phase UPS for Facility and Infrastructure Systems
Many infrastructure environments require more than distributed 10 kVA protection but cannot accommodate large centralized UPS cabinets. The Li90 20 kVA provides high-capacity lithium UPS protection in a compact footprint suitable for facility electrical rooms, telecom infrastructure, and distributed building systems.
Typical deployment environments:
- Telecom and communication rooms
- Facility electrical rooms
- Hospitality and casino infrastructure
- Industrial control systems
- Edge and distributed IT sites
- Small central equipment rooms
Internal Runtime Flexibility in a Compact 20 kVA Cabinet
The Li90 20 kVA provides scalable internal lithium runtime using modular battery blocks integrated within the UPS enclosure. This allows extended backup duration without external battery cabinets while preserving a compact footprint.
Internal runtime options:
- 15 minutes — 2 battery modules
- 22 minutes — 3 battery modules
This internal runtime capability is uncommon in compact 3-phase UPS systems, where competing 20 kVA platforms typically require external battery cabinets to achieve extended backup duration.
Key advantages:
- Extended runtime without external cabinets
- Compact installation footprint
- Simplified wiring and deployment
- Reduced floor loading
- Flexible runtime selection
Lithium UPS Architecture Eliminates External Batteries
The Li90 20 kVA integrates lithium iron phosphate batteries within the UPS cabinet, eliminating the need for external battery frames commonly required with VRLA UPS systems. This allows higher-capacity three-phase UPS deployment in constrained electrical spaces without large battery cabinets.
Architecture benefits:
- Internal lithium batteries
- Reduced installation footprint
- Simplified wiring and deployment
- Lower system weight
- Minimal maintenance access
- Faster installation

Internal Runtime vs Typical 20 kVA VRLA UPS Systems
Many conventional 20 kVA three-phase UPS systems provide limited internal runtime and rely on external VRLA battery cabinets to achieve extended backup duration.
The Li90 20 kVA integrates lithium batteries to deliver up to 22 minutes runtime within the UPS cabinet itself.
| Feature | Li90 20 kVA | Typical 20 kVA VRLA UPS |
| Internal runtime | Up to 22 min | 5–10 min |
| External cabinets required | No | Yes for >10–15 min |
| Battery technology | Lithium | VRLA |
| Footprint | Compact | Large with cabinets |
| Installation complexity | Low | Higher |
| Maintenance | Minimal | Higher |
Ideal Replacement for 20 kVA VRLA UPS Systems
Many legacy 20 kVA three-phase UPS installations rely on large external VRLA battery cabinets that consume floor space and require periodic replacement. The Li90 20 kVA replaces these systems with an integrated lithium UPS architecture offering long service life, extended runtime, and reduced maintenance.
Compared to typical VRLA 20 kVA UPS:
- Smaller cabinet footprint
- Lower system weight
- No external batteries
- Up to 22 minutes internal runtime
- Longer battery life
- Higher temperature tolerance
- Reduced lifecycle cost
