P91-10K vs Vertiv Liebert GXT5-10KHVRT5UXLN
The Xtreme Power P91-10K (paired with the BPXR3U240A pack) and Vertiv Liebert GXT5-10KHVRT5UXLN are both true online double-conversion VRLA UPS delivering full 10 kVA / 10 kW at unity PF. The P91-10K differentiates on longer baseline runtime, modular bypass/distribution, a lower rack footprint, and TAA.
What the P91-10K brings
- Longer baseline runtime (6 min vs 2 min @ 10 kW)
- Lower rack footprint (5U vs 6U)
- Optional XBDM modular bypass & distribution
- Built-in TAA compliance for federal procurement
- Scalable runtime with BPXR battery modules

Specifications from Xtreme Power’s supplied P91-10K vs Vertiv GXT5-10KHVRT5UXLN comparison; based on publicly available manufacturer data. Both deliver full 10 kW at unity PF; the P91-10K (shown with a BPXR3U240A pack) provides longer baseline runtime in a lower 5U footprint vs the Vertiv’s 6U.
Choosing between them
Both deliver full 10 kW at unity PF with equivalent warranty. The P91-10K leads on baseline runtime, rack footprint (5U vs 6U), modular bypass/distribution, and TAA; the Vertiv HVRT suits Vertiv-standardized sites favoring a single integrated chassis.
Choose the P91-10K + BPXR3U240A if you need
- Federally funded / TAA-restricted procurement
- Longer baseline runtime without external cabinets
- Lower total rack footprint for high-density environments
- Modular bypass and power distribution (XBDM)
The Liebert GXT5-10KHVRT5UXLN may fit if you need
- A single integrated UPS chassis
- Alignment with an existing Vertiv ecosystem
- Non-TAA commercial deployments with minimal runtime needs
