What You Need to Know Before Purchasing a Diesel Home Generator

Do you live in an area prone to power outages, hurricanes, and other types of inclement weather? Or perhaps you want to be able to maintain power after a natural disaster.

Either way, a diesel home generator can be a great addition to your home that can help keep you safe and comfortable during the worst conditions. But how do you choose the right one for your needs? There are several factors to consider before, during, and after your purchase.

Keep reading to learn more about diesel generators and how you can procure one for your home.

Fuel Tank Capacity and Liters/Hour of Usage

When purchasing a diesel home generator, it is essential to be aware of the fuel tank capacity and liters per hour of use in case of a power outage. The fuel tank capacity will determine how much fuel the generator can hold and how often you need to refuel it.

The liters per hour of use, in turn, will dictate how much fuel the generator uses when in operation and its overall duration of use. For example, if you have a 2,000-litre fuel tank and it uses 8 liters per hour of use, then you will be able to use it for 250 hours before having to refuel. Knowing this information before purchasing will help you make the right decision based on your specific needs and budget.

Your Power Requirement

It is important to know the amount of power you will need to generate. This can be determined by calculating your total power requirement. You can do this by taking a look at the amount of Watts (W) of the devices you plan on using and then totaling the values.

It is essential to specify the voltage you will be running, such as 120 or 230V, and decide on running the generator on single or three-phase. When choosing a suitable generator, you also need to consider the power factor (PF) of the equipment you are planning on running.

And the total power factor of the load should not exceed the stated capability of the generator. With these considerations, you can ensure you choose the right home generator for your needs. 

Working with a professional installer will help ensure that your diesel generator is properly installed and operates safely. To ensure that you get the services you need, check out these tips for hiring generator installer.

Location and Space

Make sure that you have enough room for the generator and any other accessories, such as a fuel tank, exhaust stack, or other components. It is also important to consider the noise level of the generator. If you live in a residential area, you may need to take extra steps to ensure your generator does not disrupt the peace.

Also, make sure the generator will be able to receive adequate airflow and is kept away from any combustible materials. And if you live in an area where the temperature can drop below freezing, make sure your generator will be able to run properly in cold weather. Taking these steps will help ensure that your diesel home generator is installed safely and efficiently.


If the engine fails due to normal wear and tear, the contractor will provide the parts and labor for repairs. It’s important to remember that routine maintenance items, such as changing the oil, filters, and spark plugs, lubrication, and fuel tank installation are not covered under the warranty.

To ensure a long-lasting, efficient diesel home generator, it is essential to perform routine maintenance and properly store the generator. And the warranty should provide peace of mind to the generator owner in the long term.

Learn How to Operate a Generator Safely

Generators are helpful, but if necessary safety measures aren’t taken, they could also be harmful. Here are some safety guidelines to follow when using a generator:

Read the Instructions From the Owner’s Manual Carefully

Knowing how to properly use and operate the generator is key to avoiding potential accidents or disasters. The owner’s manual will also guide fuel safety, start-up, and shut-down procedures, as well as how to properly store the diesel fuel used to home backup power generator.

It is also wise to read any warnings or cautionary notices in the manual about moving or starting up the unit. All of this information is essential for the safe and efficient use of your diesel home generator.

Use a Fuel Stabilizer When Storing Diesel for an Extended Period of Time

This will help minimize fuel degradation and the formation of gums or varnishes. The fuel stabilizer will prevent oxidation and slow the rate of fuel degradation. It ensures the diesel remains clean and free of moisture.

It is also ideal for storing diesel in powered equipment, such as outdoor power equipment, lawnmowers, and stationary emergency generators.

Avoid Refilling Your Generator When It’s Hot or Near Warm Objects

While the generator may be refilled safely when cold, using it when it’s still hot or near warm objects poses a much higher risk. The reason for this is that diesel fuel has a very low flash point, making it extremely dangerous and volatile when exposed to high temperatures. 

Keep Your Generator at Least Five Feet Away From Surrounding Surfaces

The five-foot distance helps to reduce noise and vibration levels caused by the generator. When placing the generator outside, try to keep it on a flat and even surface with good drainage. This limits the risk of the generator tipping or being affected by weather.

And make sure the generator is placed in a well-ventilated area, as any ventilation holes could fill up with debris when too close to a surface. Keeping the generator five feet away from any surrounding surfaces is an easy and important step when installation is considered.
