As someone who has installed countless backup generators for Adelaide homes and businesses over the past 20 years, we can’t overstate their importance. With our city’s frequent power outages from storms, bushfires, and excessive heat, having a reliable backup generator can be a lifesaver. It keeps your lights on, food refrigerated, air conditioning running, and critical appliances and devices powered during an extended blackout. However, selecting the right generator for your needs is crucial – it’s not a one-size-fits-all solution. Here are our top tips as electricians for choosing the perfect backup generator for your Adelaide property.
Determine your power needs
The first step is calculating your home or business’s power requirements during an outage. Make a list of the absolutely essential appliances, devices, and circuits you’ll need to run, noting their wattages. Key items may include your fridge, computer, medical equipment, sump pump, heater/AC, lights, and TV/internet. Add it all up, allowing a 20% buffer, to determine the minimum kilowatt output you’ll need from a generator. Don’t undersize it!
Portable vs. Standby generators
Portable generators are more affordable upfront but require manual setup and refuelling during use. Standby generators are pricier but start automatically when power is disrupted and run off your home’s existing gas or propane lines.
Fuel type
Common fuel options for generators in Australia are gasoline, diesel, and propane (LPG). Gas and diesel models tend to be lower cost but require refuelling every 8-24 hours. Propane burns cleaner but storage tanks may be required.
Get the right generator size
Size up, don’t downsize! Here are some common generator sizes and wattage outputs:
- 3,000 – 4,000 watts: Bare essentials like lights, fridge, TV in a small home
- 5,000 – 8,500 watts: Can power heating/AC, more appliances in a medium home
- 10,000 – 15,000 watts: Runs most home circuits, small businesses
- 20,000+ watts: Large homes, job sites, restaurants, offices
Key generator features:
- Electric start and automatic transfer switch for convenience
- Low-oil shutoff and overload protection for safety
- Adequate fuel tank size (8+ hours of runtime)
- Weather-proofing and noise dampening
- Wheel kit for portability (if portable model)
- aussie tough build quality from trusted brands like Honda, Yamaha, Kohler
Consider installation requirements
Proper installation is critical for safe generator operation. Standby units need dedicated circuits and fuel lines installed by an electrician. You’ll also need adequate ventilation as generators produce carbon monoxide. Many Adelaide jurisdictions have permitting requirements too.
Budgeting for the total cost
Don’t just look at the generator’s sticker price. Also account for accessories like cover/enclosure, maintenance kits, fuel storage, and installation costs if hiring an electrician. Higher quality generators are more expensive upfront but more reliable long-term.
Importance of maintenance
Like any engine-powered equipment, generators require regular maintenance to stay in reliable operating condition. This includes oil changes, filter replacements, exercising the generator monthly, and having an electrician inspect the system annually.
Conclusion
As tempting as it may be to buy the cheapest generator you can find, resist that urge. An inadequate or unreliable unit won’t do you much good in an emergency. Work with an experienced Adelaide electrician to size your generator properly and have it installed safely. A quality backup generator is affordable peace of mind power protection for when you need it most.
