1.5 kVA Online Lithium UPS Comparison for IT, Edge, and Regulated Deployments
The Xtreme Power P91-1.5kLi from Xtreme Power Conversion and the Vertiv Liebert GXT5Li-1500LVRT2UXL from Vertiv are both 1.5 kVA lithium based UPS systems designed to protect IT, network, and edge infrastructure.
Both platforms use lithium iron phosphate battery technology and deliver equal real power output. However, the P91-1.5kLi is engineered for longer battery service life, higher temperature operation, faster recharge, and eligibility for government procurement, while the Vertiv system prioritizes longer internal runtime in controlled environments.
