Ai90 vs Vertiv Liebert GXT5
This comparison spans two different classes: the Ai90 is a 50–60 kW (400/230V) integrated rack-level three-phase system, while the Vertiv Liebert GXT5-20KIRT9UXLN is a 20 kVA / 20 kW UPS deployed per load or rack, typically requiring an external maintenance bypass module. It contrasts a fully integrated rack-level system with a distributed, multi-component deployment — useful when deciding between one larger integrated platform and many smaller units.
Where the Ai90 leads
- A single integrated 50–60 kW system per rack instead of many 20 kVA units.
- Higher rack density (>4.6 kW per U vs >1.5 kW per U).
- Higher online efficiency (96.5% vs 95%).
- Maintenance bypass integrated in the enclosure — no separate 4U external bypass module.
- Longer runtime at a matched 20 kVA load (15 min vs 4 min), per the supplied comparison.
Ai90 and Liebert GXT5-20KIRT9UXLN, side by side
| Specification | Xtreme Power Ai90 | Vertiv Liebert GXT5-20KIRT9UXLN | Advantage |
|---|---|---|---|
| UPS architecture | Modular rack-integrated | Standalone rack UPS + external components | Integrated system architecture |
| Deployment model | Single system per rack / row | One UPS per load or rack | Simplified system design |
| Capacity | 50 or 60 kW (400/230V) | 20 kVA / 20 kW | Higher system capacity |
| Scalability | Modular within a single system | Add additional UPS units | Unified scalability |
| Voltage | 400/230V (3-phase + N) | 400/230V (3-phase + N) | Equivalent voltage coverage |
| System footprint | 13U integrated | 13U (5U UPS + 4U battery + 4U bypass) | Single integrated system vs 3 components |
| Power density | >4.6 kW per U | >1.5 kW per U | Higher density |
| Efficiency (online) | 96.5% | 95% | Higher efficiency |
| Battery integration | Internal modular | Internal VRLA | Comparable internal battery |
| Runtime @ 20 kVA | 15 min | 4 min | Significantly longer at matched load |
| Runtime strategy | Internal or external batteries | Internal or external batteries | Equivalent flexibility |
| Maintenance bypass | Integrated in enclosure | External 4U module (VMBC-20KIRT4U) | No additional bypass hardware |
These are different classes: one integrated 50–60 kW rack system versus a 20 kVA standalone unit with external bypass. For high-density, larger-scale needs the Ai90 consolidates UPS, battery, and bypass into one platform with higher capacity, density, efficiency, and longer runtime at a matched 20 kVA load. Confirm GXT5 specifications against current Vertiv documentation.
Choosing between them
Choose the Ai90 for larger-scale, high-density environments where one unified rack-level platform simplifies deployment and scaling. The GXT5-20KIRT9UXLN fits localized protection of an individual load or rack, where a single 20 kVA unit meets the requirement.
Choose the Ai90 if you need
- A single integrated rack-level system
- Higher capacity (50–60 kW) per rack
- Higher density and efficiency
- No separate external bypass module
The Liebert GXT5-20KIRT9UXLN may fit if you need
- Localized protection of an individual load or rack
- A single 20 kVA unit meets the requirement
- Distributed per-rack UPS deployment is preferred
