The Xtreme Power Conversion P91-10K (paired with the BPXR3U240A battery pack) and the Vertiv Liebert GXT5-10KHVRT5UXLN are true online, double-conversion UPS systems designed for mission-critical IT and infrastructure loads. Both systems use VRLA battery technology and deliver full 10kVA / 10kW (unity power factor) output.
However, the P91-10K configuration emphasizes longer baseline runtime, modular bypass and power distribution, reduced rack footprint, and built-in TAA compliance, while the Vertiv HVRT prioritizes a single integrated 6U UPS chassis with shorter internal runtime.
