Are you considering investing in a diesel generator? Are you having a hard time finding the best diesel generator for home use?

If so, you’re in the right place. Listed below are seven great options you might want to consider.

Benefits of a Diesel Generator

There are lots of benefits that come with using a diesel generator to power you’re home. The following are some of the primary reasons why people prefer them over other generator options:

  • Reduced flammability and increased safety
  • Increased fuel efficiency
  • Longer shelf life and less maintenance
  • Increased versatility
  • A hassle-free purchase process for diesel fuel

Last, but not least, diesel generators can also produce electricity for longer periods of time than other generators. If you want to rest easy knowing that your home will have an uninterrupted power supply, diesel is your best bet.

Why are Standby Generators Better than Portable Generators?

When the electricity goes out, the first thing anyone does is to turn on the generator so the power can be restored. You can either have a portable generator or a standby generator to generate the electricity. We have argued that standby generators are better than portable generators, let’s see why that is.

A standby generator should be installed through a transfer switch; if that is so, then as soon as the electricity goes out, the generator will start supplying the power to the house in a matter of seconds.

You won’t even notice that there is a blackout. But for the portable generator, all the process is manual, and you will have to do it yourself. Also, when the power comes back, a standby generator will be turned off automatically opposite to the portable generator, which will need to be stopped.

A standby generator can power the hardwired appliances as it directly gets connected to the house circuits, whereas it is not possible with the portable generator.

A portable generator is designed so that it can be transported to a camping site or to power an RV. This means on-site fuel storage is necessary. While standby generators sit at one place and mostly use natural gas as fuel. And in most of the houses, the natural gas supply already exists. This means no need for onsite fuel storage.

Portable generators will need to be refueled once they utilize all the fuel, but a standby generator connected to the natural gas supply will keep generating electricity without the need for refueling.

Another benefit of having a standby generator is its self-diagnostic runs, and it will run automatically weekly to see if there are any problems with the working. If there are then, it will notify the homeowners to take a closer look. If you can’t stand noise, you can consider buying a good quiet generator.

How to Choose the Best Diesel Generator for Home Use

When it comes to shopping for a diesel generator, there are some key factors you ought to consider. Remembering the following factors, in particular, will help you ensure you’re getting the best generator for your home:


First, think about the size of the generator you’re considering buying. Will you be able to store it easily on your property? Do you want it to be small enough that you can take it with you if you need to evacuate your home?


Diesel generators come with a wide range of features. This might include things like display warnings for low fuel or poor performance and the ability to deliver analysis data. Consider which features matter most to you when shopping for a generator.

Power Management

Many generators also come with a Power Management System (or PMS). This system helps the user to optimize fuel consumption and generator performance to ensure that it provides power for as long as it’s needed.

It also helps to prevent engine damage to the generator, which could shorten its lifespan.

Fuel Efficiency

In general, it’s best to look for the most fuel-efficient generator possible. It’s true that it’s relatively easy to get your hands on additional fuel if needed. However, it’s better to have a fuel-efficient model so you’re not spending more money than you need to to keep the generator running.
