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.

Prices are a guide only and may vary depending on system selection, property layout, and installation complexity. We provide free quotes with clear, upfront pricing and no surprises.

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.
