Vertiv's Lithium-Ion Single Phase UPS Models

Vertiv, a global provider of IT infrastructure and continuity solutions, today announced the availability of lithium-ion models of the VertivTM Liebert® PSI5 uninterruptible power supply (UPS) family. The Liebert PSI5 is the first single-phase UPS from Vertiv available with lithium-ion batteries. With their increased runtime and reduced maintenance requirements, lithium-ion batteries are a natural fit for deployments at the edge of the network, where IT support is limited. The Liebert PSI5 lithium-ion line interactive UPS is available now for customers in the U.S. and Canada, in 1500VA and 3000VA capacities.


The lithium-ion option eliminates the weakest link in the power chain at the edge, doubling the battery life and reducing total cost of ownership (TCO) by up to 50% compared to traditional valve-regulated lead acid (VRLA) batteries. The Liebert PSI5 leverages the superior energy density of lithium-ion batteries to enable significantly longer runtime in a similar footprint. It delivers up to 20 minutes of runtime at half load and 9 minutes at full load – roughly double that of similarly-sized UPS systems – and is well suited for small spaces in distributed networks. The Liebert PSI5 comes with a five-year advanced replacement warranty, contributing to a significantly lower TCO.

The Liebert® PSI5 with lithium-ion batteries comes with a battery management system (BMS) that provides real-time monitoring of battery conditions and ensures safe and reliable operation. 

Liebert PSI5 lithium-ion models will also be eligible for the recently announced Vertiv™ Trade-In Program. This program enables customers to trade in almost any aging single-phase UPS – Vertiv and competitive systems – for discounted pricing on new Vertiv Liebert PSI or Vertiv™ Liebert® GXT UPS systems. The Trade-In Program also includes free shipping and recycling of the surrendered UPS units, in compliance with the Recycling Industry Operating Standard (RIOS).
