Backup Power Systems Installation in Centurion
Keep the lights, fridge, internet and security on through every outage in Centurion.
Inverter and battery systems for Centurion freehold homes, sectional-title townhouse complexes and small offices, planned around the space and approvals you have.
What matters for a Centurion property
A freehold house in Centurion often has a garage or an outside wall where the inverter and battery can sit, which keeps the equipment out of living areas and simplifies cable runs to the distribution board. Ventilation and safe clearance around the unit still need to be checked before the position is finalised.
In a sectional-title townhouse complex the picture changes. The unit owner may need trustee or body corporate approval before installing equipment that sits on or near a common wall, and cable routes through shared areas are usually agreed during the site visit rather than assumed.
For a small office, the loads that stop work the instant the grid drops — computers, the network, a server and the security system — drive the system size. The final equipment choice and where it mounts depends on what the site assessment finds.
What can stay on
A starting list of the loads usually worth backing up. Final sizing is confirmed on site.
- Indoor lighting
- The fridge and freezer
- The home Wi-Fi and fibre router
- A computer and a point-of-sale terminal
- Security cameras, recorder and alarm
- The complex gate motor, where compatible
How it works
Cut the mains
A backup power system keeps your essential circuits running when the grid drops. Try the simulation below to see how power flows from the mains, through the inverter and battery, to the circuits you choose to back up.
- Lights
- Fridge
- Router
- CCTV
- PCs
Normal supply: mains power passes through the inverter to your essential circuits.
This is a visual simulation only and does not control physical electrical equipment.
Sizing estimate
How big a system do you need?
Wattages are typical estimates. Actual equipment consumption and the final system specification must be confirmed during a site assessment.

Suggested inverter
3 kVA
Estimated battery
5.12 kWh
Our smallest system is 3 kVA with a 2.56 kWh battery.
Inverter size allows for start-up surges from motors like fridges. Battery size allows for usable capacity and conversion losses. Geysers and stoves are best left off the battery. This is a starting figure, not a quote.
This calculator is a preliminary sizing aid and does not replace a site assessment, inverter compatibility checks, battery discharge limits, surge assessment or final electrical design.
The process
How your backup power installation works
- 1
Site walk-through
Walk the property together and list the loads you want kept running, noting where the distribution board and any available garage or outside-wall space sit.
- 2
Check approvals
Where the property is sectional title, confirm what the body corporate or trustees require before installation work can begin.
- 3
Written quotation
Receive an itemised quotation covering the inverter, battery and the circuits to be backed up.
- 4
Agree the position
Confirm where the equipment will mount, how it is ventilated and how cables reach the board.
- 5
Installation
Fit and label the system, working around your schedule where practical.
- 6
Mains-cut test
With you present, switch off the mains and confirm each chosen circuit stays on.
