If you’re in a hurry and want to know what is the best diesel generator for backup and emergency power supply, I recommend the Cummins generators are the best choices.

Today diesel generators are part of everyday life and provide primary and backup power to America’s industries and homes. If a diesel generator is part of your everyday life, you will be used to the sound of it supplying your electricity. 

You will also understand a diesel engine’s idiosyncrasies and its capacity to run forever. The agricultural industry, especially farmers in inaccessible regions, has put its trust in diesel generators for many years. 

At sea, purpose-built diesel engines have been used by sailors at sea almost as long as they have been used o land. If you need a reliable power source, there is a generator to fit the need. 

The choice is endless, from the small and easily transportable diesel generators to diesel generators that need heavy equipment to move them.

What Are Diesel Generators Good For?

Why Do You Need It?

So why would I need a diesel generator you ask yourself? Well, maybe you want to cut electricity costs and need a generator to supplement solar energy? 

Maybe you live in an inaccessible region where a diesel engine would be your primary power source? Maybe you are sick of the unreliability of your local electricity provider? 

Whatever the reason, no matter the situation, there is a diesel generator to meet your needs.

Simple Design

The great thing about diesel generators is their simple design concept. They regularly survive gas engines on a ratio of ten-to-one. This can be the sole testimony a lot of people require to buy a diesel generator. 

Let us take a look at the common movable gas-powered generator. It can only operate for about 1000 hours before it requires replacement, or an entire inspection and major repairs. 

Numerous cheaper generators sold by cut-rate stores and hardware retailers could not achieve 200 hours of reliable running time. 

In comparison, the same-sized movable diesel generators have a normal life of close to 20,000 hours before anything other than everyday upkeep is needed. 

Bigger diesel generators will operate more than 50,000 hours before they require maintenance. Anyone not utilizing their portable diesel generator very much may never need to service it.

Easy To Maintain

Preventative maintenance is the key to keeping diesel generators in good running order. Regular oil changes every 100 hours are recommended or follow the original manufacturer’s guidelines. 

Changing oil is simple. Just remove the oil drain plug and the oil will drain out. Then, all you need to do is, refill with clean oil. 

That is the sum total of your preventive upkeep to keep a diesel generator in good running order. No hidden extras. No endless trips to the retailer for warranty work or repairs. 

A diesel generator does not have spark plugs, a distributor, magneto, or a carburetor. So there are no parts that can burn out,

They’ll Last Longer

Diesel generators are much more expensive than their competitors, but a diesel generator will outlast most of them.  Many believe diesel fuel is harder on its surroundings as it creates more fumes. 

This is incorrect. If you apply good practice with regular upkeep on a diesel generator, you should only see smoke briefly under a strong load shift. Gasoline is more poisonous than the fumes from a diesel generator. 

Kubota, Detroit, Cummins, and even Honda, create diesel generators using state-of-the-art diesel technology.  

More and more manufacturers are mindful of the effects on the planet, so many of their new models run “clean”, to protect our health and our surroundings.
