What to Look for in a Generator

Purchasing a 400 KW generator is essential for any business that can’t afford to lose power. It’s especially useful if you have special items that need to remain at a specific temperature or you have power-operated doors and locks.

But before you choose the first 400KW generator, you should consider a few factors. Not every generator is going to suit your business, and the best generator for another company may not be for you.

Depending on your business and office or retail space, you should consider everything from the size and type to special features and fuel options.

It is also important to decide whether you want to purchase a power system that has a brushed or a brushless alternator. Brushless alternators are considered to be more efficient of the two options but will come at a higher price.

Then, you can choose the right 400 KW generator for your company. Here are some things to look for when reading generator reviews.

Size

If you know you need a 400 KW generator, you should consider how big the unit is. Some generators may take up more space, and you’ll need a bigger area to store them.

However, you may be able to find a relatively compact generator. Then, you can use it no matter how much extra space you have.

If you’re unsure if 400 KW is the right option, consider the size of your space. For a retail space, you can add 50 KW with 10 watts and divide that by the square footage to get the right KW for you.

Commercial spaces can use that same formula but start with 30 KW instead of 50. Then, add the 10 watts and divide by the square footage of your commercial space.

If your generator is too small, it won’t be powerful enough when you need to use it. But if it’s too large, it can be a waste of money upfront and when you need it.

Type

You can find a variety of generator types available, and you should consider which type is best for you. First, you could select a standby generator that you install permanently.

You won’t have to worry about storing it or setting it up when you need the power. Most of these generators have way more than 400 KW, but they’re worth considering if you have a massive space.

A portable generator can be a good option if you don’t own your office space. If you need to move to a new location, you can take the generator with you.

An inverter generator is a good choice if you want more efficient power. They also don’t make much noise, which can be useful as well.

However, an industrial generator is what you need in the case of a business. The other types can work in a pinch, but an industrial generator will give you the power and features that you need.

Features

Some generators have special features that can protect you, your employees and your office. You don’t have to choose a 400 KW generator with these features, but you should know they’re out there.

One fantastic feature to consider is automatic CO shutoff. If a generator with this feature detects carbon monoxide, it will shut down. Some engines also use low levels of CO to further protect you.

You can also look for a generator that starts automatically or is easy to start. Then, you won’t have to worry about setting it up and powering it on.

It can also help to find a generator that shows the fuel level and can power down when the fuel is low. You won’t have to risk running out of fuel, and you’ll know when to replace it.

The best generators are built with drip proof construction, which means that fuel won’t leak out. This feature ensures optimum performance and ensures that you don’t waste any diesel fuel.

Another optional element to look out for when buying a generator set is a sound attenuated enclosure. Gas generators have these to minimise the noise that is produced by open units. This is ideal for generators that are to be used in a commercial or domestic setting. Generators can produce around 60 hz of noise if sound attenuated enclosures aren’t fitted.

Consider the power type that the generator uses. Some smaller generators use propane or even batteries, but most industrial generators use diesel.

Power systems come with a wide variety of optional equipment that can improve the efficiency of your generator.

By reading generator reviews, you can figure out what features people like or don’t like. Then, you can figure out which is the best generator for you.

Price

You should also consider the price of a given generator before you buy it. While you may have a big budget to spend, you want to consider the price and the value.

Compare the features, size and type to the list price. You may find that a more expensive generator is worth it due to special features.

On the other hand, a cheaper generator may not have the features you want. In that case, buying it would be a waste of money.

Now, no two businesses have the same budget, and no generator is perfect for two businesses. You should consider everything you possibly can about a unit before you select it.

And if you can’t find the right generator, you can look at the used market for a model that you might like.

Used vs New

If you have a tighter budget or want more options, you should consider new and used generators. While a new generator may look nice and shiny, a used model can be as effective.

You may be hesitant to buy something used, but it can be a great way to save money. Opening up to used generators can also help you find a more advanced option.

The best diesel generator for you may not be available new, but there may be a used 400 KW generator. If you don’t even consider used options, you’ll limit yourself.

So if you want to be pickier about the price or the features, you can consider new and used. Then, you won’t have to limit yourself as much, so you can find the perfect 400 KW generator for you.

The 400KW Natural Gas Generator You Need

Whether you are starting a company or need new equipment, a generator can come in handy. And for some spaces, a 400 KW generator provides just enough power but not too much. If you’re still unsure whether a 400kw generator is right for you, check the rated load of the generator that you wish to buy.

Before you select one, consider the size and features, and don’t be afraid of used models.

9 Questions to Ask When Looking for a Diesel Generator for Sale

Portable generators have continually increased in popularity over the past decade or so, but especially in the last few years. These machines are great assets to have on hand when an emergency strikes to keep you from having to go without power. 

The benefits of having a generator are pretty clear but finding the right one can be more tricky. Often it’s an investment, so you don’t want to make the wrong choice. 

Luckily for you, we’ve compiled a list of the top nine questions to ask when looking for a diesel generator for sale to make sure you get your money’s worth! 

1. Is it the Right Size?

When you’re thinking about how to choose a diesel generator, you’ll need to figure out where you want to put it first. 

Generators come in all different shapes and sizes depending not the specific machine you choose. There’s no sense in looking at machines if you don’t know which will fit in your spot and which won’t. Knowing the right size will allow you to narrow down the search field and make the decision much easier. 

Measure all of the dimensions and keep that in mind as you begin your search. 

2. Do I Want a Standby Vs Portable Generator?

Next, you should look into what type of generator you’d like and if standby vs portable generators. Both of these operate in a very similar fashion but with a key difference. 

A standby generator is installed in place and doesn’t ever move. It’s always ready to be used regardless of the situation. A portable generator is often stored in a separate location and brought out when it’s needed. They both offer great power sources but have different maintenance. 

3. How Efficient is the Unit?

New vs used generators isn’t as big of a question as how efficient the unit is. The mechanics of the machine is more important than whether it has been used before to determine if you’ll get your money’s worth. 

You want a generator that will use its fuel as efficiently as possible. Some machines will require you to use way too much fuel without much output of power, this will end up costing you much more in the long run. Checking for efficiency and output capacity is an important step in finding the right generator.  

4. Will it Produce Enough Power?

As you’re checking efficiency, you can also check how much power it will be able to put out while being run. 

It’s helpful to know how much power you’ll need in an emergency situation to run the things that are absolutely necessary. That way you can match that need with machines that will only meet those requirements. This ensures that you aren’t left having to decide what gets power and what doesn’t in an emergency. 

5. What Kind of Fuel is Needed?

One of the biggest deciding factors in how efficient a generator is and how much power it will produce is what type of fuel it uses. 

The types of fuel all have their pros and cons, it’s up to you and your specific situation to decide which is best. But it’s important to look into all options before making your decision. 

It’s also important to keep in mind if you’ll be able to keep that fuel in stock and ready to go in the case of an emergency. Having a generator for emergency preparedness doesn’t do much good if you don’t have the fuel it will need to run as well. 

6. How Loud Will it Be?

No matter which kind of generator you decide to get, it’s going to make some noise. They all do when they’re in use, it’s just a fact of life. 

But some generators have added technology that makes them slightly quieter than others. Depending on where you’re using the machine, you may need to look more closely into the noise levels. 

7. Are There Remote Capabilities?

Depending on where you’re needing to use a generator, it might be a good idea to see if there are any extra management capabilities that would be helpful. Most notably would be a remote operating system. 

If your generator is for a business, it’s likely that you won’t be present at the business when the emergency strikes. Being able to turn on and access your generator from wherever you are is a game-changer for keeping things under control. 

8. What Kind of Maintenance is Required?

Generators are an investment and something that shouldn’t be taken lightly. That means that regular maintenance should be performed to keep it in the best working order possible. 

Every generator has its own unique needs as far as maintenance is concerned, which is why it’s important to understand before committing to a specific machine. Luckily, most don’t require a lot more than regular inspections and occasionally starting it up to make sure it’s running and ready for you when you need it. 

9. Can I Add On to This Unit?

Everyone knows that things don’t stay the same for very long. There are always things adjusting and shifting to meet new needs. This includes power supplies, which can change over time to match your home or business situation.

When searching for a portable generator, it’s smart to look ahead and understand if the same unit could be added to meet a growing need. There are many configurations you can use with generators, so it’s helpful to know what’s available and possible for your machine.
