Australia Generator Buying Guide and Tips

• Right size: Add up essentials (fridge, lights, pumps, tools). Most homes need 2–7 kW inverters; farms/worksites may need 10–45 kVA diesel units.
• Noise levels: Inverters: 50–60 dB @ 7 m. Open-frame petrol: 70–85 dB. Enclosed diesel: 65–75 dB. Check local council rules on noise.
• Fuel choice: Petrol for light loads/camping. Diesel for long runtimes, farms, and standby systems. LPG/dual-fuel for flexibility.
• Safety: Use licensed electricians for wiring. Install a compliant changeover/ATS—never back-feed the mains grid.
• Power quality: Protect electronics with pure-sine inverters or AVR-equipped sets + quality surge protectors.
• Cords & outlets: Use 230 V Type I cords rated for your load. Keep them dry and short, with RCD protection.
• Maintenance: Change oil after the first 20 hours, then at set intervals. Stock filters, plugs, and spare oil. Test-run monthly.
• Storage: Keep generators dry and ventilated. Consider weatherproof covers for outdoor use.

For portable units with manual transfer, budget AUD $600–$1,500 for electrical labour/materials. Standby diesel/petrol systems with ATS, cabling, and foundations may range AUD $3,000–$10,000+ depending on project scope (excluding the generator).

How noisy can a generator be in Australia?
Modern inverters are ~50–60 dB @ 7 m (similar to conversation). Open-frame petrol models can be 70–90 dB, while enclosed diesel standby units typically run at 65–75 dB. Councils may have noise restrictions.

Which generator type and fuel are best for Australia’s climate?
Petrol inverters are great for camping, caravans, and light outages. Diesel gensets suit long runtimes, rural properties, and commercial use. LPG/dual-fuel options are practical in areas with stable LPG supply.

What are the typical warranties for generators in Australia?
Portable petrol units: usually 1–3 years limited consumer warranty. Diesel standby units: 12–24 months or hour-based coverage when installed by authorised dealers. Always confirm terms in writing.
