The Xtreme Power Conversion P91-2000 and APC Smart-UPS SRT2200XLA are true online, double-conversion UPS systems using VRLA battery technology, designed to protect mission-critical IT, network, and edge infrastructure. Both deliver continuous sine-wave output and enterprise-grade power protection.
However, the P91-2000 differentiates itself with higher usable output power, a shallower rack depth, longer battery design life, stronger battery warranty coverage, and full TAA compliance, making it better suited for space-constrained deployments and federally regulated procurement environments.
