Stay Powered when it matters Most
When the power goes out, the impact depends on how prepared you are. For a family home, it might mean spoiled food and no air conditioning. For a rural property or small business, it can mean lost revenue, compromised security, or equipment damage. A properly installed backup generator system keeps your essential circuits — or your entire property — running regardless of what the grid is doing. HSJ offers a full range of services across generator backup.

generator changeover switch installation
A backup generator system has two components: the changeover switch installation and the generator itself.
The changeover switch is installed by HSJ at your switchboard. It safely connects your generator to your home or business wiring and is a legal requirement for any permanently connected generator in Queensland.
Pricing below covers the full changeover switch installation including all wiring, testing, and certification. All packages include:
- Supply and install of changeover switch (internal or external to switchboard)
- Supply and install of generator main switch
- Supply and install of indication lamps for mains and generator supply
- Compliance labels
- All wiring, fittings and testing
- Testing and installation certificate
If you’re unsure which system is right for your property, contact us and we’ll recommend the right setup.

The generator is a separate product to the changeover switch installation.
We supply and install generators tailored to each system tier, sized to run under full load for extended periods without unnecessary strain — protecting the life and performance of the unit over time.
Every generator we supply comes with:
- Full tank of fuel
- 100-hour service kit
- Customer training
- Testing alongside the changeover installation before handover
Prices below are for generator supply and installation only. If you already own a generator, we can assess it and build the changeover system around it.

Automatic vs. manual changover: Which should you choose?
A manual changeover switch is the standard choice for most residential installs. You start the generator, operate the switch, and reverse the process when mains power returns. It’s straightforward, cost-effective, and suits most homes where someone is around during an outage.
An automatic transfer switch (ATS) handles everything for you: it detects the outage, starts the generator, and switches your property across within seconds, no manual intervention required.
The right choice depends on your situation, but if you run medical equipment, operate a small business, or your property is frequently unattended during outages, automatic is worth the additional investment.
Generator Repair, Servicing and Maintenance
A generator system needs periodic testing and servicing to be reliable. Without regular maintenance, a generator that hasn’t run in months may fail to start or underperform under load, exactly when you need it most.
HSJ provides ongoing maintenance for systems we install, including:
- load testing to simulate real outage conditions,
- fluid and battery checks,
- mechanical inspection,
- and fault finding.
Contact us to arrange a service schedule that keeps your system ready year-round.
