The Xtreme Power Conversion P91-10K (paired with the BPXR3U240A battery pack) and the Eaton 9PX11KG2 are true online, double-conversion UPS systems designed for mission-critical IT and infrastructure loads. Both configurations shown here are hardwired systems intended for higher-power deployments.
However, the P91-10K configuration prioritizes longer baseline runtime, modular bypass and distribution flexibility, and built-in TAA compliance, while the Eaton 9PX11KG2 emphasizes higher nominal kVA/kW capacity in a more compact, UPS-only chassis.
10–11 kVA / 208–240V Online UPS Comparison
| Feature | XTREME POWER P91-10K + BPXR3U240A | Eaton 9PX11KG2 | XPCC Advantage |
| UPS Capacity | 10kVA / 10kW | 11kVA / 11kW | Eaton provides higher nominal capacity |
| Topology | Online Double Conversion | Online Double Conversion | Equivalent premium protection |
| System Runtime (Full Load) | ~6 minutes @ 10kW | ~3.1 minutes @ 11kW | Longer baseline runtime |
| Optional External Battery Packs | Yes (BPXR series) | Yes (9PX EBM series) | Both support extended runtime |
| Input / Output Architecture | Hardwired; optional XBDM modular bypass & distribution | Hardwired; factory-configured receptacles | Greater flexibility for service and distribution |
| Rack Height / Configuration | 5U total (2U UPS + 3U battery) | 4U total (UPS only) | Trades rack space for longer runtime |
| Form Factor | Rack / Tower | Rack / Tower | Equivalent deployment flexibility |
| Warranty | 3 years electronics 3 years batteries |
3-year limited warranty | Comparable OEM coverage |
| Compliance / Listings | UL1778, cUL, FCC, CE, RoHS, TAA | UL1778, cULus, IEC 62040-2, RoHS | P91 adds TAA compliance |
| TAA Compliance | Yes | No | Key differentiator for federal procurement |
Where the P91-10K Excels
- Federally funded and TAA-restricted procurement environments
- Installations requiring longer baseline runtime without immediately adding large external cabinets
- Deployments benefiting from modular bypass and power distribution (XBDM)
- Infrastructure racks prioritizing serviceability and lifecycle flexibility
- Projects where compliance certainty outweighs minimal rack height
When Eaton 9PX11KG2 May Be a Fit
- Existing Eaton-standardized power environments
- Deployments requiring higher nominal kVA/kW capacity in a compact UPS-only chassis
- Installations where shorter internal runtime is acceptable
- Non-TAA-regulated commercial or industrial projects
Who Should Choose Which
Choose Xtreme Power Conversion P91-10K if you need:
- Longer baseline runtime at full 10kW load
- Modular bypass and distribution for easier service and expansion
- Built-in TAA compliance for government, education, and public-sector projects
- Flexible runtime scaling using BPXR battery options
- Greater architectural flexibility for infrastructure-class deployments
Choose Eaton 9PX11KG2 if you need:
- Higher nominal capacity (11kVA / 11kW) in a compact chassis
- Alignment with an existing Eaton UPS ecosystem
- Deployment in non-regulated environments with modest runtime requirements
Ideal Applications
- Data center and infrastructure racks
- Network and telecom environments
- Government, education, and public-sector facilities
- Industrial and critical IT loads
- Projects requiring scalable runtime and service flexibility
