Power outages can strike unexpectedly, leaving us in the dark and without essential services. One of the ways these disruptions can be combatted is with the help of a generator. But what exactly is a generator, and should you consider having one in your home in Australia?

Well, that’s what we’re here to help with. In this article, we’re going to help you understand generators, including the different types that are available and their benefits. We’ll also aim to help you figure out if you should get one.

Understanding Generators

A generator is an electrical device that converts mechanical energy into electrical energy. It basically serves as a backup power source during outages or when there is no access to the main power grid.

Generators work by using an engine, usually powered by gasoline, propane, or diesel, to rotate a magnet within coils of wire, producing electricity.

There are a few different types of generators:

  • Portable Generators – these versatile units can be moved around and are suitable for powering specific appliances or tools during camping trips, outdoor events, or short power outages. However, they typically provide limited power capacity.
  • Standby Generators – designed for residential use, standby generators are permanently installed outside the house. They are connected to the home’s electrical system and activate automatically during power outages. Standby generators offer more power and are ideal for longer-lasting or frequent outages.
  • Inverter Generators – these generators are known for their fuel efficiency, reduced noise levels, and stable power output. Inverter generators are often used for recreational purposes, such as camping or powering sensitive electronics like laptops and smartphones.

How do you know if you need a generator?

There are lots of different reasons as to why buying a generator might be a good move for you. Some things to think about include:

  • Regular power outages. Does your power regularly go out? If you frequently have power outages or have experienced particularly long power outages, having a generator can make life easier.
  • Severe weather is common in your location. We have no control over the weather and unfortunately, some areas are more prone to weather conditions that can cause disruptions to your power supply. Having a generator will ensure that you’re always prepared.
  • You have critical appliances and systems. If someone in your home uses medical equipment that is electrically powered then having a generator is vital to ensure the equipment continues to operate even when there is a power outage. Other equipment that may be considered essential include refrigerators, security systems and heating and cooling systems.
  • The cost of inconvenience. It’s a good idea to evaluate the financial implications of a generator versus the inconveniences and potential damages caused by power outages. If the costs outweigh the inconveniences, investing in a generator can be a wise decision.

What are the benefits of having a generator?

Having a generator for your home or business has its advantages. Some of these advantages include:

  • Continuous Power Supply: A generator keeps critical appliances running, preserving food, medical supplies, and comfort during outages.
  • Comfort and Convenience: With a generator, you can maintain essential services like lighting, heating or cooling, and charging devices, allowing you to continue your daily activities with minimal disruptions.
  • Home Protection: During extended outages, a generator can prevent water damage from pump failures, keep security systems operational, and provide power for necessary electrical equipment.
  • Safety and Security: A generator ensures that emergency lighting, communication devices, and medical equipment stay functional, promoting safety for you and your family.

What are the downsides of having a generator?

While generators can be useful during power outages or in areas with unreliable electricity supply, there are some downsides to consider:

  • Cost: Generators can be expensive to purchase, install, and maintain. The initial investment cost, along with ongoing fuel or maintenance expenses, can add up over time.
  • Fuel dependency: Generators require a constant fuel supply, typically gasoline, diesel, or propane. This means you need to keep an adequate fuel stock and ensure it is properly stored, which can be an additional cost and logistical challenge.
  • Noise and emissions: Generators can be noisy, especially portable models. This noise can be disruptive and may not be suitable for residential areas or close proximity to neighbours. Additionally, some generators emit exhaust fumes that can be harmful to the environment and pose health risks if not properly ventilated.
  • Maintenance and repairs: Generators require regular maintenance to ensure they operate optimally. This includes tasks such as oil changes, filter replacements, and general upkeep. Repairs can also be costly if the generator malfunctions or experiences a breakdown.
  • Limited capacity: Generators come in various sizes and capacities, and it’s essential to choose one that meets your power needs. However, even larger generators may not provide enough power to run all the appliances and systems in your home simultaneously. Prioritisation and load management may be necessary during power outages.
  • Safety risks: Generators can pose safety risks if not used correctly. Improper installation, operation, or inadequate ventilation can lead to carbon monoxide poisoning, electric shock, or fire hazards. If you are considering a generator for your home, like any other kind of electrical work, you should use the service of a professional electrician for installation.

What you need to consider when choosing a generator

When choosing a generator for your home or for recreational use there are a few things you should take into consideration.

Firstly, calculate the total power consumption of the appliances and systems you want to run during an outage if it’s for your home, or if you plan to use it recreationally, what are you using it for? You need to ensure the generator’s power output meets your needs.

Secondly, consider the availability and cost of fuel types such as petrol, LPG, or diesel in your area, and choose a generator that aligns with your fuel preferences and availability.

Noise levels and local regulations regarding generator noise emissions should also be considered, especially if noise is a concern in your neighbourhood. Look for models that offer quieter operation to comply with regulations.

Finally, figure out your generator your budget for purchasing a generator and consider the long-term maintenance costs, including tasks like oil changes, filter replacements, and periodic inspections. Being mindful of these factors will help you make an informed decision that suits your requirements and budget.

Generator Installation and Maintenance

In order to ensure that your generator works properly proper installation and maintenance is a must. Here’s what you need to think about:

  • Professional Installation: Standby generators typically require professional installation to ensure proper connection to your home’s electrical system. Consult with licensed electricians or generator specialists.
  • Routine Maintenance: Generators require regular maintenance to keep them in optimal condition. This may involve changing oil and filters, inspecting fuel lines, and checking battery health. Refer to the manufacturer’s instructions or consult a professional for maintenance guidance.
  • Safety Precautions: When operating a generator, follow safety guidelines to prevent accidents. Keep the generator outdoors, away from doors, windows, or vents, and never run it in an enclosed space. Be cautious with fuel storage and electrical connections to avoid hazards.

If you need help with your generator

Generators play a crucial role in providing backup power for your Australian home during outages. Assessing your power needs, evaluating the frequency of outages, and considering essential appliances and systems will help you determine if investing in a generator is worthwhile.

If you’re not sure whether a generator is right for you or how you go about getting one, consider talking to a professional electrician for guidance, support and proper installation.
