3000VA 208/230V Online Lithium Rack UPS Comparison
Lithium-ion rack UPS systems are widely deployed in IT, network, AV, and edge environments requiring long battery life, fast recharge, and compact rack protection. The Xtreme Power P91g-3kLi and Eaton 9PX3000GRT-L are both 208/230 V online double-conversion lithium UPS platforms designed for these applications.
While both systems use lithium iron phosphate batteries and deliver similar power capacity in a 2U rack format, the P91g-3kLi provides longer runtime at higher load, significantly faster recharge, longer battery calendar life, and TAA compliance.
For deployments prioritizing lithium lifecycle durability, recharge speed, and extended runtime, the P91g-3kLi delivers a high-performance 208/230 V rack UPS platform.
