Vertiv Liebert UPS systems keep power clean and continuous across data centres, server rooms, network racks, healthcare and industrial sites, anywhere an outage or unstable mains would take critical equipment offline.
But you don't need a data centre to benefit. Whether you need a UPS system for home, an office UPS system for a few workstations or serious protection for a whole site, there's a Vertiv UPS system that fits.
We've sold and maintained over 100,000 UPS systems in the last 20+ years, so we know which model suits your setup, your budget and how long you need to stay powered.
Why Vertiv UPS Systems? The Liebert Heritage
Vertiv's data-centre heritage is where the difference shows: high-efficiency online double-conversion, modular architecture that scales in power blocks for N+1 redundancy without forklift upgrades, and the option to pair your UPS with matched Liebert precision cooling from a single vendor.
In plain English: they're efficient, they grow with you, and you can get your backup power and your server room cooling from the one brand.
If you know the name Liebert, you already know Vertiv. Liebert is Vertiv's UPS range, and Vertiv was called Emerson Network Power until 2016. When it comes to UPS systems, Vertiv is one of the most trusted names around.
Most models also take a network card, so your IT team can keep an eye on battery health and alarms from anywhere. Here's how UPS remote monitoring works.
Vertiv UPS Systems Range
From a single desk to a full data centre, there's a Vertiv model for the job. Here's the quick version:
| Series | Type | Best for |
|---|---|---|
| Liebert PSA | Line-interactive | Home PCs, modems and small desktops |
| Liebert PSI / Vertiv EDGE | Line-interactive (PSI up to 3kVA) | Offices, point-of-sale and network gear |
| Liebert GXT5 / GXT RT+ / GXT MT+ | Online double-conversion (GXT5 500VA–10kVA) | Server racks, critical and edge loads |
| Liebert ITA2 | Online double-conversion | Larger server rooms and sensitive loads |
| Liebert APM / EXS / NXC | Three-phase, modular options | Data centres, hospitals and industrial sites |
Line-Interactive Vertiv UPS: Liebert PSA, PSI and EDGE
Entry-level line-interactive backup with automatic voltage regulation and surge protection for desktops, workstations, point-of-sale, routers and small networking gear. They smooth out dips and spikes in your power without touching the battery, then switch to battery in about 2–4 milliseconds if the power drops out.
Online Double-Conversion Vertiv UPS: GXT5, GXT RT+ and ITA2
With an online UPS, your gear runs off the UPS all the time, so there's no gap at all when the power fails, and the power it gets is perfectly clean. The GXT5 is rack/tower convertible with scalable runtime for critical and edge loads. You can also swap its batteries without switching it off. It's the go-to for servers, medical equipment and anything that can't miss a beat.
Three-Phase and Modular Vertiv UPS Systems: APM, EXS and NXC
For big sites like data centres, hospitals and factories, the Liebert APM, EXS and NXC do the heavy lifting. Modular models like the APM let you add power in blocks as you grow, including a spare block as backup, instead of replacing the whole system. See our modular UPS systems and three-phase UPS systems.
Lithium-Ion Vertiv UPS Options
Vertiv's lithium-ion models, including the GXT5 Lithium and EDGE Lithium, last longer, weigh less and need fewer battery swaps over their life. Handy where space, weight or running costs matter.
Which Vertiv UPS System Do You Need?
Use the selector below to match your environment to the right Vertiv UPS or call 1300 555 992 and we'll size it for you.
Vertiv UPS System for Home
A UPS system for home keeps your NBN modem, Wi-Fi, work laptop, NAS drive, gaming PC and security cameras running when the power drops out, and protects them from surges.
So what's the best UPS system for home? Look for:
- Enough capacity: most homes need 600VA–1500VA
- Quiet running, so it can live in a lounge or study
- Clean (pure sine-wave) power for sensitive electronics
- Replaceable batteries
A Liebert PSA or Vertiv EDGE suits most UPS home system setups. If you work from home and can't afford a hiccup, step up to a small GXT MT+. New to all this? Start with our beginner's guide to UPS systems.
Office UPS System
An office UPS system has more to look after than a home setup. Workstations, phones, point-of-sale and the comms cabinet all need to stay on long enough for everyone to save their work.
A Liebert PSI covers individual desks, while a rack-mount GXT5 protects the network cabinet. Worried about fan noise in an open-plan office? Pop it in one of our soundproof server cabinets.
Server Rooms and Network Racks
For most small-to-mid server rooms, a Liebert PSI (line-interactive, up to 3kVA) or the online Liebert GXT5 (500VA–10kVA) gives reliable rack or tower protection. The GXT5 is the popular pick for critical racks.
Data Centres and Critical Facilities
Data centres need efficiency, backup for the backup and room to grow, which is exactly what the modular Liebert APM delivers. We look after it as part of our data centre and server room solutions, and can add diesel rotary UPS for the biggest sites.
Healthcare, Industrial and Security Sites
Hospitals, factories and security systems can't handle even a flicker, so an online Vertiv UPS gives them clean, gap-free power. See our medical UPS systems, UPS for security systems and ruggedised outdoor UPS.

How to Size a Vertiv UPS System
Sizing sounds tricky, but it comes down to four questions:
How much power do you use?
Add up the nameplate wattage of every device the UPS will protect and multiply by about 1.25, sizing to roughly 80% of the UPS's rated capacity, to leave headroom for growth.
How is the UPS rated?
Many current Liebert models, including GXT5 6–10kVA, have a unity power factor, so the VA rating equals the watt rating and you get more usable power per unit. In short, more of the number on the box is actually usable.
How long do you need to stay on?
Five minutes to shut down safely, or an hour until the generator kicks in? Longer runtime means extra battery packs.
How critical is it?
Must-never-fail sites need a spare module on standby. Also check your rack space and whether your site is single-phase or three-phase.
