Diesel generators are a power back-up solution for many homes and businesses worldwide. With the current load-shedding by Eskom and power outages experienced in some parts of the country from time to time, South Africans are now turning to alternative electrical power sources. Diesel generators is one of these options.
Here we will explore the pros and cons of using a diesel generator so you can make an informed decision for your business or home.
Pros of Diesel Generators
Modern diesel engines have been developed to overcome some of the drawbacks of earlier models of higher noise and maintenance costs. Let’s look at some of the major pros of diesel generators:
- Durability – As long as they are maintained well, they are much longer lasting than alternative generators. They are extremely tough and can hold up through much wear and tear in a variety of environmental conditions.
- Low maintenance – Diesel generators are known to require less maintenance than other types of generators available on the market. This is because the generator’s engine requires fewer components to start, so you won’t have to worry about changing spark plugs or rebuilding carburetors like you would have to with, for instance, a gas engine.
- High power output – Diesel generators are capable of handling larger power loads and run for longer durations than other types of generators. They are perfect for remote sites where a power grid might be unreliable or unavailable.
- Fuel efficiency – Diesel generator systems are more fuel efficient than petrol generators because diesel engines have a higher thermal efficiency. You can get more energy from diesel fuel, as it has a longer running time when operating at the same capacity.
- Continuous power supply – A well maintained diesel generator can prove very reliable and keep your critical power systems running for long periods during blackouts and/or load-shedding. this will keep your downtime to a minimum to avoid experiencing significant financial losses.
- In terms of life span, a diesel engine is much longer lasting, when compared to a typical petrol engine, a diesel engine can last up to 3 times longer than a petrol one.
Cons of Diesel Generators
- Noise – Diesel generators can be very noisy. A way to combat this is by installing a sound-attenuated generator enclosure that helps reduce the noise levels. This enclosure also provides weatherproofing to help protect the generator from exposure to other elements like dust.
- Emissions – While modern diesel generators run much cleaner than earlier models, diesel generators still produce toxic emissions like carbon monoxide and nitrogen oxide.
Maintaining a diesel generator
While maintenance requirements are low for diesel generators, some tasks will need to be done periodically. These include:
- A general inspection of all components.
- Draining and changing the coolant, oil, and fuel.
- Cleaning or replacing filters.
- Testing the generator battery.
- Running the engine to test operation.
‘ It’s also a good idea to perform maintenance whenever there has been a major weather event. For example, after a dust- or rainstorm. Exposure to dust and other airborne contaminants can greatly affect your generator’s performance, causing clogs in the filters and making your generator work harder to do the same job.’
