Why Businesses Need
Backup & Standby Power

When the grid fails, the cost to your business isn’t just about lights going out. It’s staff left idle, lost product, and in some industries, equipment damage that can run into the millions.

Lost productivity

Staff can’t work without power. Even an hour of downtime adds up in wages and missed deadlines.

Spoiled stock

Cold rooms, freezers, and food production sites can lose thousands of dollars in product within minutes.

Damaged equipment

In manufacturing, a sudden loss of power can destroy machinery. One plastics manufacturer we worked with risked losing a $1m+ piece of equipment if power failed mid-run.

That’s why so many businesses across Australia choose SGH backup and standby generators. They’re not just buying a machine — they’re buying certainty that operations continue, no matter what the grid does.

What Does “Standby Power” Mean?

Every generator has two ratings: prime and standby. The standby rating is the maximum output your generator provides during an outage — exactly what most businesses need for backup. The prime rating is used when a generator runs continuously as the main power source.

On this page we’re focused on standby and backup power.

What’s the difference between a backup generator and a standby generator?

In most cases, they mean the same thing. A backup generator provides power when the grid fails, while a standby generator is the technical term for that emergency rating. Both protect your business from costly downtime across the industries we work with.

What size generator do I need for my business?

It depends on what you need to keep running. Offices may only need 20–30kVA, while manufacturing sites might need 200kVA or more. Our team can size the right unit for your operations, and you can also get a quick estimate using our Generator Size Calculator.

How fast does a standby generator switch on?

With automatic transfer switches, most standby generators restore power within seconds of an outage.

Can I hire instead of buying?

Yes. Many businesses start with backup generator hire for flexibility, then invest in a permanent unit once they know their long-term needs. For tailored recommendations, get in touch through our Contact Us page for more information.

Do you install and service backup generators?

Absolutely. SGH provides full installation, ongoing maintenance, and compliance testing across Australia.

How much does a commercial backup generator cost?

Costs depend on size, fuel type, and installation. Smaller units may start under $20k, while large industrial systems require tailored quotes. SGH will match the right backup generator to your budget and power needs. Click the link for a quote.
