The Vertiv Liebert GXT5 Lithium-Ion is an intelligent, efficient online double-conversion UPS built for network closets, small server rooms and edge IT cabinets. The 1.5kVA model pairs a compact rack-tower chassis with a LiFePO4 lithium battery, giving you clean, continuous power, longer battery life and a lower total cost of ownership than a comparable lead-acid UPS. It is part of the GXT5 Lithium-Ion 1kVA to 10kVA family, all sharing the same lithium platform, communications and 5-year warranty.

Lithium-ion is a step change for UPS batteries. Compared with valve-regulated lead-acid, it offers greater power density, up to three times the useful life, up to ten times more discharge cycles and far quicker recharge, in a smaller and lighter package. For network closets, small server rooms and edge IT cabinets, that means fewer battery replacements, fewer site visits and a set-and-forget solution. The GXT5 Lithium also tolerates warmer environments than lead-acid, so it holds up better in rooms that run hot, and its cells hold charge well in storage before commissioning.

True online double-conversion protection

The GXT5 Lithium 1.5kVA is an online double-conversion UPS, which means incoming mains is rectified to DC and rebuilt into a clean, pure sine wave by the inverter, and your load always runs from that inverter. There is no transfer time when the mains fails, and mains-borne problems such as sags, spikes, frequency drift and harmonics never reach your equipment. For network closets, small server rooms and edge IT cabinets, that is the difference between conditioned, uninterrupted power and a UPS that only reacts once a problem has already passed through.

Lower total cost of ownership

Because the LiFePO4 battery lasts far longer and endures many more cycles than lead-acid, the 1.5kVA needs fewer battery replacements over its life, which Vertiv estimates at up to 50% lower total cost of ownership. You save on the batteries themselves and on the time and labour to swap them, which is especially valuable at remote or lightly-staffed sites. Around 99% of the battery elements are recyclable, and lithium units run cooler and quieter, which reduces the cooling burden in the room.

Battery runtime

The lithium battery gives the 1.5kVA strong ride-through for its size, and runtime can be extended with hot-swappable external battery cabinets (VEBCLI-48VRT1U). The figures below are the rated internal-battery autonomy. For a runtime matched to your exact load and any added cabinets, use our UPS runtime and battery calculator.

Technical specifications

Connections and load control

The 1.5kVA connects through an IEC C14 inlet and feeds 8 x IEC C13 (two groups of three programmable). The programmable outlet groups let you shed non-critical loads first during a long outage, and a MicroPOD maintenance bypass is available for GXT5 models 3 kVA and below so the UPS can be removed for service without powering down connected equipment.

Sizing the GXT5 Lithium 1.5kVA for your site

For a single-phase load up to 1350 W, the 1.5kVA is a strong choice for a rack or a floor-standing position. Size to your measured load in watts, allow headroom for growth, and add external battery cabinets for the runtime your shutdown or generator handover needs. Because the lithium battery holds capacity longer, the same unit stays fit for purpose for more years than a lead-acid equivalent.

Communications and monitoring

The 1.5kVA ships with a USB management port and free Vertiv Power Assist and Power Insight software for local and network monitoring and graceful shutdown. An IntelliSlot bay accepts an RDU101 or RDU120 network card for Ethernet, web, SNMP and environmental sensor support, so your team can see UPS status, load and battery health remotely and integrate the UPS into building and IT management systems.

Lithium versus lead-acid: why it matters

Applications

The GXT5 Lithium 1.5kVA suits network closets, small server rooms and edge IT cabinets. Indigi deploys it across:

• Server rooms and comms rooms needing clean, protected power
• Edge and distributed IT sites where low maintenance matters
• Healthcare and cold-chain and other loads that cannot lose power
• Network and telecom cabinets, and remote sites with little on-site staff

Installation and maintenance

Indigi Power and Cooling supplies the GXT5 Lithium 1.5kVA with genuine Vertiv batteries, cabinets and accessories, and provides installation, commissioning and preventative maintenance across Australia. See our single-phase UPS installation and commissioning and UPS maintenance services. Because the battery is lithium, ongoing maintenance is minimal, but annual checks keep the warranty and monitoring in good order.

Frequently asked questions

What battery does the GXT5 Lithium 1.5kVA use?

It uses a Lithium-Ion (LiFePO4) battery, which lasts up to three times longer than lead-acid, handles up to ten times more discharge cycles, and recharges to 90% in under two hours.

Is the GXT5 Lithium 1.5kVA a true online UPS?

Yes. It is an online double-conversion UPS with zero transfer time and a pure sine wave output, so your equipment always runs on clean, conditioned power, not just battery backup during an outage.

What warranty does it come with?

A 5-year standard warranty covering both the UPS and the lithium battery, which is well beyond the 2 to 3 years typical of lead-acid UPS batteries.

How much power does the 1.5kVA deliver?

It delivers 1350 W at 0.9 power factor. Size to your real power (watts) requirement, not just VA.

Can I extend the runtime?

Yes. Runtime extends with hot-swappable external battery cabinets (VEBCLI-48VRT1U), and up to eight cabinets can be added per UPS for long-duration backup.

Does Indigi supply and service the GXT5 Lithium across Australia?

Yes. Indigi supplies, installs and maintains the GXT5 Lithium range from hubs in Brisbane, Sydney and Melbourne, with national coverage and genuine Vertiv parts.
