3 kVA Online Lithium UPS Comparison for IT, Edge, and Regulated Deployments
The Xtreme Power P91-3kLi from Xtreme Power Conversion and the Vertiv Liebert GXT5Li-3000LVRT2UXL from Vertiv are both 3 kVA online double conversion UPS systems designed to protect mission critical IT, network, and edge infrastructure.
Both platforms use lithium iron phosphate battery technology and deliver equal real power output. However, the P91-3kLi is engineered for longer battery service life, higher temperature operation, faster recharge, significantly longer runtime, and eligibility for government procurement, making it better suited for demanding and long life deployments.
Key Differentiators at a Glance
- Lithium iron phosphate battery chemistry with extended cycle life
- Significantly longer internal battery runtime at full load
- Higher ambient temperature tolerance
- Faster battery recharge for improved uptime
- TAA compliance for government and regulated procurement
- Longer warranty coverage reducing lifecycle cost
