When you run a small business, chances are you’ve got a lot of power needs. Whether you need to power an air conditioner, lights, computers, printers, vending machines, water pumps, refrigeration units, etc., diesel generators are the perfect solution.

There are lots of reasons why businesses choose to go with diesel generator solutions. They provide reliable power 24/7, even during blackouts. They’re affordable, durable, versatile, and, most importantly, safe.

But before buying a 50kw diesel generator, ensure you understand how they work and which will meet your specific needs. Here are several Tips to Decide Which Size Diesel Generator Is Right for Your Needs:

How Much Power Do You Need?

The amount of electrical power you require determines what kind of generator you should buy.

If you’re looking for a generator to run lights, fans, pumps, and maybe some appliances, you’ll want something small enough to fit easily inside your building. 

However, if you use the generator to power a whole house, you’ll probably want a larger unit.

What Type Of Load Does Your Facility Draw?

Your generator needs to be able to handle the maximum load your facility draws at any given time.

Generators designed for industrial use often have a higher output than those designed for residential use.

Will You Operate The Generator Continuously?

If not, how long will you turn it off each night? A smaller diesel generator may last longer if you only run it occasionally. However, larger generators tend to perform better if they’re left on constantly.

What Are Your Electrical Requirements?

Next, think about what electrical requirements you have. Many generators come with their own inverter, which converts AC (alternating current) electricity into DC (direct current), the type of electricity needed to power devices like lighting fixtures and computers. For a piece of in-depth information, Bravo Electro shares how to choose an AC-DC converter. Generators without their own inverter won’t work with many items.

Where Will You Be Using It?

Think about where you plan to use the diesel generator. If you live in a remote area, you may not need anything bigger than a portable model.

But if you’re planning to bring your generator outside, you’ll definitely want something larger.

Where Is The Best Place To Locate A Generator?

Generator placement depends largely on the size of your building and the location of its primary power source. Smaller generators typically sit outside, while large units are usually placed inside.

How Many Hours Per Day Does My Business Operate?

Once you have determined how many hours each day your business operates, you’ll want to know how many hours a day you need electricity.

If you run a 24-hour operation, a 2-hour standby system should provide enough power to keep everything running smoothly.

On the other hand, if you only need electricity for 8 hours per day, a 1-hour backup system may be sufficient.

What’s My Budget?

Now that you’ve got an idea of how many hours you need power, you can figure out how much money you can spend on a generator. Most companies offer financing options, so you don’t necessarily have to pay upfront.

Can I Use My Existing Equipment With It?

Many people who own generators already have certain pieces of equipment that they’d like to continue using.

If you have any equipment that requires AC power, you’ll want a generator that operates on either 120VAC or 240VAC.

Know The Difference Between Peak And Continuous Loads

Peak loads occur when all of your appliances are running at once. Continuous loads happen when you leave appliances on overnight.

Knowing the difference between these two kinds of loads will help you determine which size generator you need.

What Type Of Backup Battery Do You Want?

You’ll also want to consider what type of backup battery you want to use with your generator.

Several different types of batteries are available, including deep-cycle marine batteries, AGM (absorbed glass mat) batteries, gel cells, and lithium-ion batteries. Each type offers its own benefits and drawbacks.

Consider Feature Capabilities

When shopping for a generator, you’ll want a model that comes equipped with features that meet your needs.

For example, if you plan on operating heavy machinery, you’ll want an engine with enough horsepower to run your tools properly.

Will You Be Using It In Cold Weather Or Hot?

If you live in cold weather areas, you may consider buying a diesel generator designed to operate in freezing temperatures.

These models usually come equipped with special insulation so they won’t freeze up while running.


With so many factors to consider, choosing the right size diesel generator can seem like a daunting task. But following these simple tips will help make sure you choose the perfect generator for your needs!
