What else do Australian winters bring aside from the cold weather? Storms—and with them, unexpected power cuts that turn your home into a dark and freezing place. In these times, a backup generator can be a lifesaver. Gentrax is a trusted name providing home backup generators in Australia, bringing dependable, fuel-efficient and quiet generators for tough conditions.
The Winter Threat: Why Power Outages Are More Than Just an Inconvenience
Power cuts in Australia mean no heating, spoiled food, and disrupted work and communication. These inconveniences are not only annoying—they also pose a threat to your family’s comfort and safety.
No heating can lead to dangerously low indoor temperatures and frozen pipes. In dire situations, contacting emergency services can be difficult with your mobile phone clinging to that 1%. Your home security systems can also shut down.
This makes storm preparedness in Australia beyond merely stocking up on food. Preparing for winter storms in AU means ensuring you have enough emergency power supply. This keeps your home running, your family safe, and your stress levels low.

Choosing the Right Gentrax Generator for Your Winter Needs
Choosing a backup generator starts with knowing your power needs. What size generator you’ll need depends on your must-have appliances and whether you want to run them simultaneously or in rotation.
Add up the wattage requirements and choose a portable generator that matches the kW or higher:
Basic Needs (Under 2kW)
If you’re only powering emergency lights, phones, and a modem, you should go for light and compact models like the GT800 and GT1200, both being under 2kW. The GT800 weighs only 8.5 kg and can run 6 hours at 50% load.
Midrange (2kW to 3kW)
Models within the 2kW to 3kW range are a great balance for most households. For example, the GT2000 and GT2500 are within 16-28 kg in weight and can power a refrigerator, modem, and several lights, covering your essentials.
High Power (3kW – 5 kW)
Need more power and longer runtime? The Gentrax GT3500, GTX4200, and G3850 may be the perfect choice. They can support small heaters, kitchen appliances, and multiple devices.
Heavy Duty (Over 5kW)
Need near whole-house backup? This is the range for you. Models like the GTX6600 are great for larger homes or those with higher power demands during outages.
Essential Safety Tips for Using Your Generator in Storms
Storm preparedness means total safety from all kinds of hazards. Don’t forget to use the generator the right way. Here are some useful tips for maintaining proper generator safety:
- Never run it indoors to avoid carbon monoxide buildup.
- Keep it dry and away from windows or vents.
- Store fuel safely in approved containers and away from heat or flames.
