Generators are an essential source of power during load shedding and other power outages in South Africa. Diesel generators are particularly popular in businesses and commercial environments due to their efficiency and durability. However, the noise levels produced by generators can be a concern for businesses, particularly in high-density areas like Pretoria. In this article, we will discuss the most popular diesel generator brands in South Africa, strategies for reducing generator noise levels, and the different types of generators available. We will also provide information on how to choose the right generator size for your business, with a focus on suburbs in Pretoria. Additionally, we will address noise regulations in Pretoria and provide tips on how to comply with them.

The Best Diesel Generators

Some of the top diesel generator brands in South Africa include Cummins, Perkins, and Volvo Penta. These brands offer a range of sizes and power options to suit different needs, from small portable generators to large standby models. Diesel generators are particularly popular in businesses and commercial environments due to their reliability and fuel efficiency.

The Quietest Diesel Generators

While diesel generators are generally louder than inverter generators, there are some options available that produce minimal noise levels. Some of the quietest diesel generators include the Cummins Onan Quiet Series, which operates at only 63 decibels, and the Generac XD5000E, which operates at 70 decibels.

Choosing the Right Size Generator for Your Business

Choosing the right size generator for your business is crucial to ensure that you have enough power to meet your needs during an outage. The size of the generator you need will depend on factors like the size of your business, your power requirements, and whether you want to power the entire building or just essential equipment. In suburbs in Pretoria such as Hatfield and Menlyn, which have a mix of small and large businesses, a 20kW to 30kW generator is sufficient for most needs.

How to Reduce Generator Noise

To reduce generator noise, it is important to place the generator on a solid, level surface and to use sound-reducing enclosures or barriers. Regular maintenance can also help to reduce noise levels. In suburbs like Waterkloof and Groenkloof, which have strict noise regulations, it's crucial to minimize noise levels to avoid disturbance to neighbors. It's important to comply with Pretoria's noise regulations, which require a maximum noise level of 60 decibels during the day and 55 decibels at night.

Dial a Contractor Generator Services

Dial a Contractor is a company that offers generator installation and repair services to businesses in South Africa. Their services can help businesses choose and maintain the right generator for their needs, while also ensuring that the generator is operating at optimal efficiency and noise levels.

Diesel Generators vs. Inverter Generators

While diesel generators are generally more powerful and efficient than inverter generators, they are also louder. Inverter generators, on the other hand, are generally quieter and better suited for sensitive equipment. When choosing between the two types of generators, it's important to consider factors like power requirements, noise levels, and equipment sensitivity.


Q: Why did the generator break up with the power plant?
A: Because it found someone who fueled its engine!


By choosing the right size and type of generator and by taking steps to reduce noise levels, businesses can ensure that they have reliable power without causing disturbance to their neighbors. With the help of companies like Dial a Contractor and knowledge of noise regulations in Pretoria, businesses can enjoy the benefits of reliable power without causing unnecessary disturbance to their community.
