Uninterruptible Power Supply (UPS) Systems for Australian Businesses
When your organisation depends on critical IT and electrical infrastructure, selecting the right Uninterruptible Power Supply (UPS) is essential. From protecting servers and networking equipment to safeguarding point-of-sale systems, industrial controls and medical devices, a properly specified UPS ensures continuity during power outages, brownouts, voltage fluctuations and electrical surges.
Kickstart Computers supplies and supports commercial-grade UPS systems across Australia, including rackmount UPS, online double-conversion UPS, lithium-ion UPS and enterprise 3-phase UPS solutions. We work with industry-leading manufacturers such as Eaton, APC, Vertiv (Liebert) and equivalent professional-grade brands to deliver reliable, long-term power protection tailored to real-world business environments.
Trusted UPS Specialists Since 2007
Since 2007, Kickstart Computers has provided expert technical advice, supply and support for UPS systems to Australian businesses, government organisations, education facilities, healthcare providers and industrial sites.
Our approach is practical and vendor-agnostic — we focus on correct sizing, runtime requirements, scalability and reliability, not simply selling a product. As a certified Eaton partner, with full access to APC, Vertiv and other enterprise UPS platforms, we help customers select systems that meet both current needs and future expansion.
If a UPS model is available in Australia, we can source it — even if it is not listed on our website.

UPS Comparison: Online vs Line-Interactive vs Lithium-Ion
| Option | Best for | Power quality | Transfer time | Typical use cases | Pros | Considerations |
|---|---|---|---|---|---|---|
| Online Double-Conversion | Mission-critical uptime | Excellent (continuous conditioning) | Zero | Servers, data centres, medical, industrial automation, core network | Cleanest power, best protection, ideal for sensitive loads | Higher cost, sizing and bypass planning important |
| Line-Interactive | Cost-effective business protection | Good (voltage regulation) | Brief (milliseconds) | Offices, POS, desktops, comms racks, small servers | Great value, efficient, widely available | Not ideal for highly sensitive/critical environments |
| Lithium-Ion (Battery Option) | Lower maintenance / longer life | Depends on UPS topology (online or line-interactive) | Depends on topology | Edge sites, comms, harsh temps, sites with difficult maintenance access | Longer battery lifespan, faster recharge, lower maintenance, better TCO | Higher upfront cost; confirm compatibility and monitoring requirements |

Enterprise UPS Replacement Case Study (NSW)
Client: Steven, IT Systems Administrator
Organisation: Large hospitality & community venue
Location: Sydney, NSW
The client contacted Kickstart Computers after their existing 10kVA three-phase UPS suffered a critical failure. Due to the nature of the breakdown, the organisation specifically requested non-APC replacement options.
Kickstart Computers conducted a technical comparison of Eaton, Vertiv and PowerShield enterprise UPS platforms, assessing:
Load requirements and runtime expectations
Physical footprint and weight considerations
Serviceability and long-term reliability
Maintenance bypass and monitoring requirements
Based on this evaluation, the client selected an Eaton 91PS enterprise UPS, supplied with an external maintenance bypass switch, network management card and additional backup battery capacity.
The result was a more robust, scalable and serviceable UPS solution, aligned with the venue’s operational risk profile and future expansion requirements.
Client Feedback:
“The replacement UPS solution exceeded expectations in terms of build quality and robustness, and we were confident proceeding after reviewing the alternatives provided.”

Uninterruptible Power Supply (UPS) Systems FAQ
Â
The correct UPS size depends on the total power load (watts or kVA), the type of equipment being protected, and how long the system needs to run during an outage. Allowing headroom for future growth is also important when selecting a UPS.
Online double-conversion UPS systems continuously condition power and provide zero transfer time, making them suitable for servers, data centres and critical systems. Line-interactive UPS systems are more cost-effective and are commonly used in offices, POS environments and general business applications.
For most server rooms and data centres, an online double-conversion UPS is recommended because it delivers clean, uninterrupted power and protects sensitive equipment from voltage fluctuations and power disturbances.
ithium-ion UPS systems typically offer longer battery life, faster recharge times and lower maintenance requirements than traditional VRLA battery systems. They can be a good option where long-term reliability and reduced battery replacement cycles are important.
UPS runtime depends on the connected load and the size of the battery system. Reducing the load or adding external battery modules can increase runtime to meet specific business continuity requirements.
Battery lifespan varies based on battery type, operating temperature and usage. VRLA batteries generally require replacement every 3 to 5 years, while lithium-ion batteries typically last longer under similar conditions.
A maintenance bypass is strongly recommended for many enterprise and three-phase UPS installations, as it allows servicing or replacement of the UPS without interrupting power to critical equipment.
Yes. UPS systems help protect equipment from power surges, voltage dips (brownouts) and other electrical disturbances. Online double-conversion UPS systems provide the highest level of power conditioning.
A three-phase UPS is designed for higher-capacity environments such as data centres, hospitals, manufacturing facilities and large commercial sites. It is typically required when power loads exceed the limits of single-phase systems or where redundancy and scalability are needed.
Many commercial and enterprise UPS systems support network monitoring cards, allowing administrators to monitor status, receive alerts and perform graceful shutdowns of connected equipment during power events.
Yes. Kickstart Computers supplies and supports UPS systems Australia-wide and can assist with system selection, sizing, monitoring and battery replacement for single-site and multi-site organisations.
