Best Portable Generators for Professional Use 2018

Not a lot can be said about the difference between a generator for home use or for professional use. They are actually pretty similar when it comes to features and specs. However, what draws the line between the two would be their design and durability.

The best professional generators aren’t always the bulkiest, heaviest, loudest or most powerful. Although some of these characteristics are often attributed to generators for professional use.

Basically, what separates a generator for professional use from those for home use would be their rugged design? This would allow the generator to withstand the rigors of operation in a construction site as well as transportation.

Can it easily be hoisted up a crane? Will it endure wear and tear? Is it powerful enough yet clean to provide power for even the most sensitive construction equipment? These are just some of the important questions to ask when buying the best portable generators for professional use.

Features

As we’ve mentioned earlier, there aren’t really so many features to expect from a portable generator for professional use. However, there are essentials that you wouldn’t want to skip out on.

An example of a most important feature of a professional generator must have would be a pure sine wave technology. This makes it possible for a generator to produce minimal total harmonic distortion (THD). Meaning, it is suitable for even sensitive devices.

Safety features such as a low oil shutdown, electric circuit breaker/GFCI, and internal air cooling system are also among the most important. These would help keep the user and the generator engine safe from potential damages and/or dangers during long operations.

What To Look For

We’ve mentioned earlier the features that are essential in a professional generator. But to be more specific, there are some things you must look out for before buying. First off, does it come with a warranty? Or any sort of money guarantee?

Since you will be using the generator at job sites for professional use, you’ve got to make sure that it doesn’t suddenly break down on you. And when it does, you’ve got to be sure that you can get it replaced or repaired.

Another thing to look out for would be again, design and durability. Is the frame or enclosure sturdy enough to withstand working conditions in a job site? Can it be easily hoisted up on a crane? Is the engine durable as well?

Is it powerful enough for all your equipment yet clean and stable for the most sensitive ones? Moreover, does it have safety features to keep you safe from overheating, overloading and the like?

Finally, does it come with a wheel kit? The professional generator is already as bulky and heavy as it is. The most important part is it comes with tools to increase portability.
