Running out of power during working hours is really annoying and can cause heavy loss. Diesel generators are a quick solution, but they come with some hidden problems that not everybody knows. These include noise, fuel costs, and many other headaches. So, before you invest, it’s crucial for you to understand the downsides of a diesel generator so that you don’t get surprises later. So, keep reading!
1) High Installation and Setup Costs
When you buy a diesel generator, the total cost is more than just the machine. You also pay for the setup and installation. It puts an extra burden on your pocket. Generally speaking, installation can add 20 to 40% to the total cost of the generator. You have to buy wiring, control panels, a ventilation system, and exhaust systems.
Moreover, you need a strong place to put it. For this, you may need soundproof rooms and fire safety systems. You know, all this setup needs money. If you hire skilled workers for installation done correctly, it will increase the cost further.
For example, if you install a generator for your industry, only the setup can cost you thousands of dollars. So, for small businesses and homeowners, it would be a heavy investment. Therefore, before choosing a diesel generator, keep these hidden costs in mind. Yes, otherwise they can affect your budget more than you think.
2) High Fuel Cost and Price Fluctuations
Another disadvantage of diesel generators is their high cost of fuel. Diesel is expenive than other fuels. So, if you run your generator for long hours, costs can add up quickly. And, in the long run, fuel becomes one of the continuous biggest expenses.
It is also worth discussing that the prices of diesel don’t stay stable. Yes, because of the market changes, government taxes, and global oil prices, the price of diesel can rise suddenly. That’s why it becomes difficult for you to predict your monthly expenses.
For example, if a business uses a 10 kVA diesel engine, it can spend thousands of dollars on just the fuel for the generator. In fact, if the price rises, the number can increase further. So, fuel cost is really a serious consideration for those who are going to buy a diesel generator.
3) Need for Maintenance and Repair
Although diesel generators are powerful, they need regular care. Yes, they need a proper schedule for maintenance. If you miss that, it will start creating problems. Yes, unlike other machines, you can’t just keep running the machine and forget it. Ignoring the maintenance can develop problems that become costly if not given attention on time.
Regular maintenance of a diesel generator includes checking the filters, coolant, and changing the oil. Apart from this, you have to properly check the batteries, engine parts, and fuel lines. All thsi need time and effort, but don’t skip it, it’s crucial to avoid serious breakdowns.
For example, you own a car. You drive it daily and never check its filters or change the oil. Obviously, the engine will start wearing out. A diesel generator behaves the same; the difference is that the generator parts are bigger, ultimately, repairs cost more.
In addition, wear out may use more fuel, adding extra cost. Well, for businesses and hospital who reply on diesel generators on a daily basis, it is crucial to be serious about the maintenance of the diesel engine, as it helps avoid bigger problems during busy hours.
| Maintenance Activity | Recommended Interval | Estimated Cost |
| Engine Oil Replacement | Every 250 running hours | $100-$300 per service |
| Air Filter Swap | Every 500 running hours | $50-$150 |
| Fuel Filter Change | Every 500 running hours | $30-$80 |
| Cooling System Inspection | Every 500 running hours | $100-$200 per inspection |
4) Loud Noise
A diesel generator also produces noise. If you use the generator near home, hospital, or office, it really affects the comfort and puts strain on nerves. You know, a constant, loud sound disturbs us humans.
For example, you are at home trying to sleep while the generator is running. The noise will make it hard for you to rest. And, if you are in the office and trying to focus on the project, the noise of the generator can distract your mind. Even if you use soundproofing, you will feel the vibration and humming.
You know, other generators, like electric generators, run quietly. But a diesel generator uses powerful combustion and produces a loud noise from the engine and exhaust system.
It is also worth discussing that this continuous loud sound can affect your health. It can lead to headaches, hearing problems, and stress. So, for residential areas and workplaces, noise is really a big concern.
5) Environmental Impact
Although diesel generators are helpful in completing your pending tasks, they have a serious impact on the environment. When a diesel generator starts combusting the fuel, it produces harmful emissions, which are released in the environment. On average, if a diesel generator uses 1 liter of diesel, it emits about 2.7 kg of CO₂.
Apart from CO₂, diesel generators also produce other harmful substances like carbon monoxide, nitrogen oxides, and tiny particles. These pollutants are harmful to your health and risky to breathe. Although it is harmful for all, people with asthma and lung problems should be more careful.
In addition, these pollutants are also contributing to changing the climate. That’s why European regulations and the Paris Agreement aim to reduces teh emission of greenhouse gases. So, we can say that in the near future, the machines producing harmful gases would be replaced by greener alternatives, like solar and natural gas.
Think of a small shop in a town. It uses a diesel generator daily. It adds to the pollution of the local area more than the cars on the streets. So, it is evident that if diesel generators are reliable, they are not environmentally friendly. So, choose a cleaner energy option or use the generator only when you can’t do without it.
6) Large Size and Heavy
Diesel engines are large and heavy. They are difficult to move and can’t fit in small spaces. Other machines, like electric generators, are portable; you can carry them easily anywhere. But it is really a daunting task to move the diesel from one place to another.
For example, if you want to add a diesel generator to your shop, you have to find a safe and final corner for it. Yes, moving it requires special equipment and more people, which adds costs and effort. Generally speaking, due to the weighta nd size of these generators, they are also difficult to install. They need a strong strong for placement.
Moreover, they need special equipment, extra space for ventilation and exhaust systems, and a lot of effort. It also needs to be discussed that when you buy a diesel engine, delivery charges may be higher than those of other machines, due to its size and weight. So, before investing in a diesel generator, keep this factor in mind.
7) Fuel Storage Concerns
A diesel generator needs a steady supply of fuel to run. So, you must store the fuel safely. The storage becomes a problem when you have limited space. Moreover, if you store the fuel improperly, it can be dangerous. It can lead to leaking, spilling, and even fire incidents.
It is crucial to follow the safety rules. Place the fuel tank away from the heat sources, buildings, and people. However, it is a challenge for homes and businesses to find a safe and suitable place for storing fuel. Moreover, if you run the generator regularly, you need more tanks of fuel, which requires extra space and budget.
For example, if a small workshop uses the diesel generator for several hours of the day, it needs hundreds of litres of diesel ready to pour. Otherwise, it will be risky and inconvenient.
8) Performance Issues with Different Loads
Diesel generators only work well with the right load. If you put extra pressure on them, they can’t perform efficiently and may even get damaged. This is the common disadvantage of a diesel generator that people usually ignore.
As high load is not good, low load is also not good; it causes carbon build-up, reduces efficiency, and increases fuel consumption. In contrast, overloading puts strain on the engine. Both situations increase the costs of maintenance.
It is worth noticing that you should use the generator compatible with the application. For small appliances, a small generator would be enough; it will wastage of money and effort.
9) Safety Risks
A diesel generator should be handled properly; it can be dangerous. One of the main risks is the release of carbon monoxide. This gas is invisible and deadly. If you run the genrator indoor or in a place with poor ventilation, you can put yourself and others at risk.
Fuel spills and leaks are another problem. You know, diesel is flammable, so it should be handled amd store carefully, otherwise it can lead to fire hazards. Electrical wires or a nearby heat source can make the situation worse. Apart from this, you know generators have running parts and high temperatures. Don’t touch it while it’s working; it can cause burns.
So, place the generator outside, keep fuel away from the electrical connections and hear, and follow the instructions given by the manufacturer. Remember! Your safety is the top priority!
