The process of generator connection and installation requires a lot of hard decision-making. Generators come in many shapes and sizes, but they can also be manufactured by many different companies. It is essential to choose the brand that is best suited to your needs. This part of the equation is critically important for industrial applications because the power generation needs here are very complicated. The right generator brand can offer you all the requirements you need for large-scale emergency backup use for running essential industrial equipment and machinery. Each brand comes with its own benefits, and we’ve put together a list of the best generator brands to suit your power usage requirements.

What is the best generator brand for industrial applications?

There are a number of popular brands for industrial generators in Australia. Some of the manufacturers that will be mentioned below can easily build units of up to 700kVa or more. These are usually for larger-scale industrial purposes used for backup/standby power where a power supply is essential. You should research the best brands for your unique installation whether you need a generator for a construction site or a resort, these are two different properties that need power generation for different reasons. There are a couple of features to look out for in a generator and they include brand reputation, specialization, and versatility. The brand you choose will need to suit your specifications, but you should also consider your requirements. The brand that you choose also depends on your budget, operational noise output, uninterrupted run-time, and overall performance. There are specific features unique to each brand and that will decide what is best for you:

  • Noise level or Noise-reducing mechanisms
  • Dimensions and weight
  • KVA output – prime or standby
  • Fuel economy and performance
  • Warranty and generator servicing

The best generator brands

  • Perkins industrial generator

Perkins standby generators are a well-known name for diesel generators in Brisbane’s industrial market and the brand name has proven itself to be very effective. Perkins’s generators are flexible enough to meet the needs of any commercial and industrial requirements and the range of diesel units brings added benefits. Perkins has a capacity of up to 2250kVA for commercial & industrial needs in Brisbane.

  • Perkins’s generators come with advanced monitoring systems that will help you to keep up with the health of your diesel generator, fuel levels, and any faults that may need checking.
  • Perkins’s generators can work in any environment and climate. The engine and the parts that work with it are meant to be quiet, for all commercial applications, but tough and efficient for even the most demanding industrial environment.
  • Extended Warranty: Perkins’s generators come with manufacturer warranties ranging from 1-3 years in duration, which depends on the specific model and desired usage conditions.


  • Generac industrial generators

Generac industrial generators are built to last and they are known for this because they can easily survive extreme weather conditions and run-on liquid propane, which is more efficient than petrol or diesel and requires less maintenance. Generac is known across the country for having rigorous run times and very lengthy lifespans which make them the perfect application for industrial properties. They are also best for industrial properties because they thrive in rural areas where there may not be consistent access to power. They can also help with regulatory requirements linked to noise level outputs.

  • Generac produces industrial generators that are not as heavy as other brands. This is also the case when compared to Cummins generators. There can be a difference of 60kgs between models of the same size.
  • Generac prices are cheaper because they have manufacturing plants everywhere including Australia, which means the distribution prices are lower.
  • Cummins industrial generators 

Cummins is another well-known brand across the country for industrial uses. Cummins is a global brand that is recognized for its capability to manufacture some of the most silent models on the market. While other industrial generators can offer their own benefits, they cannot match the brand’s sound level capabilities. Certain parts of Brisbane, and the greater Queensland area, are considered as havens of peace and quiet away from urban noise and are places where the natural environment should be heard. This is typically the case for the more rural areas, and this is exactly where many industrial locations are located. Therefore, there are strict rules to be followed about the artificial noises made on your property from sources like generators because they shouldn’t disturb other people’s enjoyment of the area. Cummins generators have sound levels that have been known to be as low as 62 decibels which can be highly advantageous for industrial use because it keeps owners in compliance with local noise permittance regulations.

  • Cummins is known to be a more high-quality product due to the price and it is because of this that they are less prone to breaking down than other brands.
  • They are exceptional at performing in cold weather and can rival any other generator brand in this aspect. It is also versatile enough to survive very high temperatures but may need servicing to keep up with hot weather.
