How to Choose a Diesel Generator: The Ultimate Guide for Tasmanians

Why Diesel Generators Are Essential

For homeowners, businesses, and tradespeople in Tasmania, having a reliable power source is critical. From storm-induced outages to powering construction sites or events, diesel generators offer durability, fuel efficiency, and long-term reliability.

 But with so many options available, the question arises: how to choose a diesel generator that meets your needs?

At DGA Power Anytime, we help Tasmanians select the perfect diesel generator by considering power requirements, fuel efficiency, portability, and long-term maintenance. This guide provides everything you need to make an informed decision and ensure your investment delivers maximum value.

Why Diesel Generators Are Popular in Tasmania

Diesel generators are a preferred choice for many Tasmanian businesses and households because of their:

  • Fuel efficiency,  Diesel engines consume less fuel per kilowatt of electricity compared to petrol engines.

  • Durability and longevity, Diesel generators can operate for thousands of hours with proper maintenance.

  • High power output, Ideal for industrial applications, construction sites, and large homes.

  • Lower fire risk, Diesel is less flammable than petrol, making it safer in certain environments.

These features make diesel generators highly suitable for Tasmania’s unique energy needs, from urban areas to remote rural locations.

Step 1: Determine Your Power Requirements

The first step in choosing a diesel generator is calculating how much power you need. Consider:

  • Essential appliances: Fridges, freezers, lights, heaters, or computers.

  • Business equipment: Tools, machinery, or servers.

  • Events, Lighting, audio-visual systems, or catering equipment.

Generators are rated in kilowatts (kW). Make a list of all devices you want to power simultaneously and total their wattage. This will help you choose a generator with sufficient capacity, ensuring it runs efficiently without overloading.

Step 2: Consider the Type of Diesel Generator

There are several types of diesel generators to choose from:

Standby Generators

Designed for home or business backup during power outages. They automatically start when electricity fails.

Portable Generators

Compact and easy to transport. Suitable for small jobsites, outdoor events, or recreational use.

Industrial or Commercial Generators

High-capacity generators for factories, large businesses, or ongoing construction projects.

Choosing the right type depends on whether your priority is portability, automatic backup, or high continuous output.

Step 3: Assess Fuel Efficiency and Tank Capacity

Fuel efficiency determines how long your generator can run on a single tank of diesel. Generators with larger tanks can operate for extended periods without refueling, which is especially important during storms or extended blackouts in Tasmania.

Diesel engines are naturally more efficient than petrol, and modern generators often include features like:

  • Eco-mode operation

  • Load sensing to adjust fuel consumption

  • Efficient engine design for lower consumption per kW

Step 4: Check Noise Levels

While diesel generators are generally louder than petrol models, modern designs focus on reducing noise through:

  • Soundproof enclosures

  • Mufflers and exhaust silencers

  • Proper installation and placement

For Tasmanian homes, offices, or events, low-noise diesel generators are essential to avoid disturbing neighbors or clients.

Step 5: Consider Portability and Size

Portability depends on how you intend to use the generator. Small portable models can be wheeled or lifted easily for outdoor events or mobile work sites. Larger industrial generators require professional installation and may not be easily moved, but offer higher power output and durability.

At DGA Power Anytime, we guide Tasmanian customers in selecting the right balance between size, portability, and power requirements.

Step 6: Look for Safety Features

Safety is critical when operating diesel generators. Key features to consider include:

  • Automatic shut-off for low oil or overload

  • Circuit breakers to protect connected equipment

  • Emergency stop buttons

  • Proper ventilation and exhaust systems

These features prevent damage to both the generator and your appliances, ensuring safe operation for your home or business.

Step 7: Evaluate Maintenance Requirements

Regular maintenance is crucial for extending the lifespan of a diesel generator. Maintenance tasks include:

  • Checking oil levels

  • Cleaning fuel filters

  • Inspecting and replacing air filters

  • Running the generator periodically to prevent component degradation

Choosing a reliable local supplier like DGA Power Anytime ensures Tasmanian customers have access to service, spare parts, and professional guidance, keeping their generators in peak condition.

Step 8: Consider Your Budget and Long-Term Value

While diesel generators often cost more upfront than petrol units, their long-term efficiency, durability, and lower fuel costs make them cost-effective over time. Factor in:

  • Initial purchase price

  • Fuel consumption and operating costs

  • Maintenance and spare parts availability

  • Longevity and resale value

Investing in a high-quality diesel generator from a trusted supplier ensures you get the best return on your investment.
