2 kVA Online Lithium UPS Comparison for IT, Edge, and Regulated Deployments

The Xtreme Power P91-2kLi from Xtreme Power Conversion and the Vertiv Liebert GXT5Li-2000LVRT2UXL from Vertiv are both 2 kVA online double conversion UPS systems designed for mission critical IT, network, and edge environments.

Both platforms use lithium iron phosphate battery technology and deliver equal real power output. However, the P91-2kLi is engineered for longer battery service life, higher temperature operation, faster recharge, longer runtime, and federal procurement eligibility, making it better suited for demanding and long life deployments.

Key Differentiators at a Glance

  • Lithium iron phosphate battery chemistry with extended cycle life
  • Longer internal battery runtime at full load
  • Higher ambient temperature tolerance
  • Faster battery recharge for improved availability
  • TAA compliance for government and regulated procurement
