Single Phase UPSInstallation and Commissioning Australia
Direct answer
A single phase UPS runs from a standard 230V supply and covers roughly 1 to 20kVA. Below about 3kVA it is usually plug connected and can be positioned by site staff; above that it is normally hardwired to a dedicated circuit, which makes it licensed electrical work requiring a certificate of compliance under AS/NZS 3000.
Indigi Power and Cooling installs and commissions single phase UPS systems across Australia from $850 ex GST, in comms rooms, server rooms, medical practices, retail back of house and small office floors.
The threshold
Where plug-instops working
Single phase is the size band where the largest number of Australian businesses sit, and it is also where the most corners get cut. A 1kVA tower under a desk genuinely is a plug-in appliance. A 10kVA floor-standing unit feeding a comms room is not, and treating it like one creates a compliance exposure that surfaces at the worst possible moment.
The practical dividing line is the 10A general power outlet. A standard GPO delivers about 2.3kW, so once a UPS needs more than that on its input it cannot be fed from a normal socket. Some units in the 3kVA band use a 15A outlet, which is still plug connected but needs a dedicated 15A circuit installed. Above that, the unit is hardwired.
The second thing that pushes a job over the line is battery runtime. Extending a single phase UPS beyond its internal batteries means an external battery cabinet, and that brings cabling, weight, ventilation and AS 2676 considerations that a plug-in install never has to think about.
Indigi Power and Cooling is Indigenous and Veteran-owned, Supply Nation and ICN Gateway registered. Our installers are licensed electrical workers, and every hardwired install leaves with a compliance certificate and a signed commissioning record.

- External battery cabinets where runtime demands it
- Comms rooms, server rooms, practices, small floors
Form factor
Rack, tower or floor standing
The mounting decision is made early and is expensive to reverse, because it drives rack space, floor loading, cable routes and how the unit is serviced.
| Format | Typical capacity | Installation considerations |
|---|---|---|
| Rack mounted, 2U to 6U | 1 to 10kVA | Consumes rack units that could hold equipment. Check rail depth and rack weight rating, especially with extended battery modules. Servicing usually means sliding the unit forward, so the rear needs slack |
| Tower | 1 to 3kVA | Simplest install. Needs floor space with clearance for ventilation. Suits practices, retail back of house and small comms cabinets |
| Convertible rack or tower | 1 to 10kVA | Useful where the room may be racked later. Confirm orientation before install as the display and feet differ |
| Floor standing | 10 to 20kVA | Hardwired. Check floor loading and access route including lift capacity and door widths. Needs front and often rear service clearance |
| External battery cabinet | Any, for extended runtime | Heavy. Floor loading, ventilation and AS 2676 apply. Cable run between UPS and cabinet must be kept short and correctly rated |
Commercial
Single phase installation pricing
Australian rates, ex GST, covering installation and commissioning. Equipment is quoted separately.
Positioning, connection, commissioning and handover. Often plug connected at this size, so frequently a same-day job.
Hardwired to a dedicated circuit with isolation provided, commissioned and certified under AS/NZS 3000. The most common single phase install we do.
Hardwired with external battery cabinet and maintenance bypass where specified. Access and floor loading checked at inspection.
Add-ons priced at quote: new dedicated circuit where none exists, maintenance bypass switch, external battery cabinet, network management card and monitoring setup, out of hours work, and removal and disposal of an existing unit.
Scope
What the install includes
Load assessment and sizing check
We measure the actual load rather than adding nameplate ratings, which routinely produces a smaller and cheaper UPS than a paper calculation. We also check headroom, because a UPS should sit around 80 per cent of capacity at most to hold its rated runtime.
Supply and circuit work
Confirming the board has a spare way and adequate capacity, installing a dedicated circuit where the unit is hardwired, and providing isolation so the UPS can be worked on without dropping the room.
Physical installation
Racking or positioning the unit with correct service clearances, installing any external battery cabinet, cable termination, earthing and labelling. Old unit removed and disposed of if we are replacing one.
Commissioning and transfer testing
Battery string voltage, polarity and torque checks, transfer testing on line to battery and back, load testing at the real load, and runtime verification so you know what you actually have rather than what the brochure claims.
Monitoring and handover
Network management card configured, alarms and shutdown software set up where required, compliance certificate and commissioning record issued, and a maintenance schedule handed over with the site.

Questions
Single phaseinstall FAQs
What people ask before booking a single phase install. If yours is not here, call 1800 046 344.
What is a single phase UPS?
A single phase UPS runs from a standard 230V single phase supply, the same supply that feeds general power outlets in most Australian buildings. Capacities run from around 500VA up to about 20kVA. Above that, and in any building with a three phase supply feeding a significant load, a three phase UPS is normally used instead. Single phase units cover comms rooms, small server rooms, medical practices, retail back of house and small office floors.
Can I install a single phase UPS myself?
Only if it is plug connected. A UPS that feeds from a standard 10A or 15A outlet can be positioned and plugged in by site staff, though it should still be commissioned and load tested properly. Once a unit is hardwired into the distribution board, which is typical above about 3kVA, it becomes fixed electrical wiring and must be installed by a licensed electrical worker and certified under AS/NZS 3000.
How much does single phase UPS installation cost?
Indigi Power and Cooling installs single phase UPS systems from $850 ex GST up to 3kVA, from $1,250 for 3 to 10kVA and from $1,800 for 10 to 20kVA. Those figures cover installation and commissioning; the equipment is quoted separately. Adding a new dedicated circuit, a maintenance bypass switch, an external battery cabinet or out of hours work is priced at quote.
What size single phase UPS do I need?
Size to the measured load, not the nameplate ratings, and leave headroom. A UPS running at more than about 80 per cent of its capacity loses runtime quickly and has no room for growth. As a rough guide, a small comms room with a couple of switches and a firewall usually sits under 1kVA, a single well-populated rack around 3 to 5kVA, and a small server room 6 to 15kVA. We measure at site inspection rather than estimating.
Should the UPS be rack mounted or floor standing?
Rack mounting keeps everything in one cabinet and is tidy, but it consumes rack units you might want for equipment, and extended battery modules consume more. Check the rack weight rating before committing. Tower and floor standing units free up rack space and are easier to service, but need floor area with ventilation clearance. Above about 10kVA the decision is usually made for you, since the unit is floor standing.
How long will the batteries last?
Three to five years for standard sealed lead acid batteries in a temperature-controlled room, shorter where ambient temperature is high. Battery life is the single biggest factor in whether a UPS performs during an outage, which is why we hand over with a maintenance schedule and recommend runtime verification at least annually rather than trusting the front panel.
Can you replace an existing UPS without downtime?
In most cases yes. Where a maintenance bypass exists we transfer the load onto it and swap the unit live. Where there is none, we can install a temporary bypass or schedule the brief interruption out of hours. Retrofitting into a room with no bypass provision is the situation worth raising at site inspection, because it changes both the method and the price.
