Single-Phase UPS Installation | Brisbane Sydney Melbourne
Licensed UPS installation for server rooms, healthcare, retail and small data halls, 500VA to 20kVA.
UPS Services delivers single-phase UPS installation for server rooms, comms cabinets, healthcare equipment, retail point-of-sale, and small data halls across Australia. Our licensed electricians install UPS systems from 500VA to 20kVA, including line-interactive and online double-conversion topologies.
Every installation is performed by qualified electrical workers in accordance with AS/NZS 3000 (Wiring Rules), AS IEC 62040 (UPS systems) and AS/NZS 5139 where lithium battery systems are involved. We deliver full pre-commissioning checks, load bank verification on request, and structured commissioning reports for compliance.
We install and support all major manufacturer brands: APC by Schneider Electric, Eaton, Vertiv Liebert, PowerShield, Socomec, Riello and Salicru, with manufacturer-trained technicians and warranty-aligned workmanship.
Correct sizing starts with the inputs: a measured load audit in watts, the power factor of the equipment (modern IT loads are typically 0.9 to unity), a headroom margin for growth, and the runtime you need before either the load can shut down cleanly or a generator takes over. From there we choose the topology. Line-interactive UPS with automatic voltage regulation suits offices, point-of-sale and less critical comms where a few milliseconds of transfer is acceptable. Online double-conversion (VFI) suits sensitive or critical loads because it rebuilds the waveform continuously and transfers to battery with zero break, fully isolating the load from sags, surges and frequency drift.
Every installation ends with a documented commissioning handoff: pre-energisation checks, polarity and earth verification, battery connection and charge confirmation, an on-load transfer test to prove the UPS supports the real load, alarm and shutdown configuration, and a walk-through with your team. You receive a commissioning report, a Certificate of Compliance for the electrical work, and warranty registration, so the asset is audit-ready from day one.

Frequently asked questions
6 questions answered.
Q01
What size single-phase UPS do I need?
Add up the wattage of all equipment to be protected, multiply by 1.25 for headroom, and convert to kVA (watts ÷ 0.9 power factor). For a typical small server room of 8 servers + switches drawing ~3kW, a 5kVA online UPS with 15-minute runtime is a sensible starting point. Our team performs a free load assessment to confirm.
Q02
How long does a single-phase UPS installation take?
Most rack or tower installations complete in 2–4 hours per UPS, including pre-commissioning and walk-through. Larger jobs with new circuit work typically take a half day. Critical environments may require after-hours installation to avoid load disruption, and we plan that with you in advance.
Q03
Do I need a licensed electrician for UPS installation?
Yes. Any installation that connects to the building electrical supply must be performed by a licensed electrician under AS/NZS 3000. UPS Services uses fully licensed electricians on every install and provides a Certificate of Compliance (CoC) for your records.
Q04
Can you install lithium-ion UPS systems?
Yes. Lithium-ion UPS installations must comply with AS/NZS 5139:2019 (Battery system safety) which covers location, ventilation, and fire-protection requirements. Our team is trained on lithium UPS specifically and can advise on retrofit suitability.
Q05
Line-interactive or online double-conversion: which single-phase UPS do I need?
Line-interactive UPS uses automatic voltage regulation to correct sags and surges and switches to battery on mains failure with a short transfer time of a few milliseconds. It is cost-effective and well suited to offices, retail point-of-sale and less critical comms equipment. Online double-conversion (VFI) UPS continuously rebuilds the output waveform from the DC bus, so the load is fully isolated from mains disturbances and there is zero transfer time when mains fails. It is the right choice for servers, medical devices, laboratory instruments and any load sensitive to power quality or frequency variation. We recommend the topology based on load criticality, the local power quality, and whether a generator is present.
Q06
What information do you need to quote a single-phase UPS installation?
The essentials are the total load to protect (in watts, ideally measured rather than nameplate), the required runtime before clean shutdown or generator handover, the physical location and ventilation of the UPS and batteries, and any growth you expect over the next few years. A photo of the existing switchboard and the equipment to be protected helps, and we can run a free load assessment on site. With that we size the UPS in kVA and runtime, recommend a topology and battery chemistry, and quote the full installation including any circuit work and certification.
