Vertiv Liebert GXT5 Online UPS: Specs, Sizing, and Service
The Vertiv Liebert GXT5 is a premium online double-conversion single-phase UPS from about 0.5 to 20 kVA, protecting servers, network closets, and edge sites with pure sine-wave output and zero transfer time. A lithium-ion version (GXT5LI) delivers roughly three times the battery life with a five-year warranty. Comp-Utility, a long-standing Vertiv distribution partner, supplies and services the GXT5 across Central Texas.

Frequently Asked Questions
What is the Vertiv Liebert GXT5?
The Liebert GXT5 is a premium online double-conversion single-phase UPS from about 0.5 to 20 kVA. It continuously regenerates clean power with pure sine-wave output and zero transfer time, protecting servers, network gear, and edge equipment. A lithium-ion version offers extended battery life with a five-year warranty.
Is the GXT5 a true online UPS?
Yes. The GXT5 uses double-conversion (online) topology, meaning it continuously converts incoming power to DC and back to clean AC, fully isolating the load from utility disturbances with zero transfer time. This is the highest level of protection for sensitive single-phase equipment, compared with line-interactive designs that switch to battery during an event.
What is the benefit of the lithium-ion GXT5LI?
The lithium-ion GXT5LI provides roughly three times the battery service life of VRLA, backed by a five-year warranty, plus faster recharge and tolerance of higher temperatures. For edge and distributed sites, fewer battery replacements mean fewer service visits and lower total cost of ownership over the UPS life.
How do I size a GXT5 for my equipment?
Sizing is based on the connected load in watts or VA and the runtime needed before shutdown, generator start, or restored power, with headroom for growth. Comp-Utility calculates the load, recommends the GXT5 rating and runtime, and can add extended battery cabinets where longer backup is required.
Can the GXT5 be monitored remotely?
Yes. The GXT5 supports network management cards for SNMP and remote monitoring, providing visibility into status, load, and battery health, and integrating with DCIM platforms. Comp-Utility can deploy units with monitoring configured so your team is alerted to issues before they become outages.
Who supplies and services the GXT5 in Central Texas?
Comp-Utility, a long-standing Vertiv distribution partner, supplies, deploys, and services the Liebert GXT5 across Central Texas, including battery testing and replacement and fleet support. Call (512) 346-0999 or email sales@comp-utility.com to source units or set up service.
How does the GXT5 compare to the APC Smart-UPS and Eaton 9PX?
All three are respected single-phase platforms. The GXT5 and Eaton 9PX are online double-conversion units for sensitive loads, while the APC Smart-UPS line spans line-interactive and online (SRT) models. As a vendor-agnostic provider and partner of all three manufacturers, Comp-Utility recommends the platform that best fits your load and standardization preferences.
How often should GXT5 batteries be replaced?
VRLA batteries in the GXT5 typically last three to five years, while the lithium-ion GXT5LI lasts considerably longer with a five-year warranty. Runtime shortfalls or replacement indicators signal the need to act. Comp-Utility tests and replaces batteries to keep rated runtime intact across distributed deployments.
My UPS is in alarm, what do I do?
Call Comp-Utility right away at (512) 346-0999, and have the unit's model and serial number ready along with any alarm codes or messages shown on the UPS display. A unit in alarm can indicate a battery, load, or power-path issue that needs prompt attention. Because we maintain a large base of units under contract with the major UPS manufacturers, we can escalate directly to the right factory resources and coordinate service faster and more directly than a single end user calling general support, often getting you answers and a technician on site sooner.
