Buying guide

To work efficiently on a construction site, you need power tools. So you need a reliable power source. The best generator for a jobsite has enough power to meet all of your electrical demands and a gas tank large enough to run all day.

We've reviewed dozens of generators to find the best option for contractors and professionals. The Yamaha EF7200DE stands out for its fuel efficiency and extremely long run time, even at rated load, as well as its relative portability compared to other large commercial generators. Still, there were plenty of good options, and we'll highlight five other models in addition to the EF7200DE.

We put a lot of thought into our review, but the most important consideration was the peak and continuous power each generator could provide. On top of that, we looked for engine reliability, run times long enough to power you through a full day's work, plenty of power outlets to meet the needs of different tools, and GFCI protection to keep you going. security. Below are reviews of our favorite generators, along with a buying guide to help you choose the best generator for your job site.

Why do you need a generator for professional use for a construction site?

Generators for professional use are not cheap. So, do you really need an off-the-shelf generator rather than a cheap consumer generator?

In short, the answer is yes. Professional use generators are built to withstand much more heavy usage than the average consumer generator. While a homeowner may only run their device a few times a year, a jobsite generator will be used day and night for hours. Your generator's engine is therefore under a lot of pressure, and generators for professional use are designed to meet this demand.

In addition, generators for professional use come with many features that can significantly increase productivity and safety on a jobsite.

Jobsite generators also come with a variety of power outlets, beyond the standard 120-volt duplex. Most of the generators we've reviewed are capable of delivering 240-volt power to power power-hungry tools, and there are usually several twist-lock 30-amp outlets you can take advantage of. Professional generators also emphasize electrical safety, backing outlets with GFCI circuits to prevent dangerous power surges.

Features to Consider in a Contractor Generator

There are many options for choosing the best jobsite generator for your job. Here we'll go over some of the features you need to think about when choosing the model that's right for you.

A reliable engine

The motor is the heart of every generator, and it's the component that will take the brunt of the wear and tear from everyday use. It is therefore extremely important that your generator engine is reliable and durable.

All of the generators we have reviewed come from companies with excellent reputations for engine construction and life. We have checked these models to ensure that users have not had engine degradation issues over several years of professional use. Of course, it is important to ensure that you properly maintain your generator engine with oil and filter changes to get the maximum life out of your generator.

Fuel tank capacity and operating time

If you work on a construction site, time spent without electricity is a waste of productivity and money. It is therefore important to look for a company generator that can run all day without refueling stops. Of the generators we reviewed, only the Yamaha model offers eight hours of runtime at its rated load of 6,000 watts. However, all of the other generators we reviewed offer at least 7.5 hours at 50% load, and some can run at over 6,000 watts for an entire day.

Safety Features

Your power tools are likely to draw a lot of power from your generator at high currents, so safety is extremely important. All the generators we reviewed are equipped with an automatic low oil shutdown, which shuts down the engine if the engine oil is too low, to prevent engine damage and electrical overload. . They are also all equipped with an overload prevention device, which also shuts off the generator if you have too many tools plugged in.

A very useful safety device to look for is the GFCI circuit that relies on all outlets. This device is available on the Honda EB10000 and saves you the worry of an electrical surge that could damage your tools or electrocute one of your employees. Many other generators we have reviewed, including Yamaha, Generac, and Cat models, only offer GFCI protection on 120-volt duplex outlets.

Commercial warranty and customer service

While problems with the generators we've reviewed are rare, it's good to know that your expensive generator is protected in case something goes wrong. Many companies offer a three-year warranty on their generators, even if you're using them for a commercial application like powering a job site. However, beware that some companies, like Westinghouse and Generac, reduce their warranty to just one year for commercial operators.

Dimensions, weight and portability

Powerful commercial generators are not lightweight. Most of the models we reviewed weigh over 90 pounds. But that doesn't mean you shouldn't think about portability. Even if you leave your generator on a construction site for weeks, sooner or later you will have to move it from one site to another. When that time comes, it's extremely useful to have sturdy pneumatic wheels and a steel frame. Also, look for metal plates that you can hook a towing device to, like on Westinghouse, Yamaha, and Honda generators.

Ease of use

Generators are largely easy to use, but there are a few features that can improve the experience. The most important is an electronic starting system, which saves you from having to operate a recoil starter to start the engine of your generator. All of the generators we reviewed have an electric start system and many have a spare recoil cable.

Another useful tool is a display panel or analog voltmeter that allows you to monitor the amount of power you are drawing from your generator. An electronic display panel also shows the remaining run time, which can be useful if you plan to plug in another tool when the fuel tank is empty

Finally, adding fuel and oil should be easy. This is the case on all the generators we reviewed, but it's worth checking out the process if you're looking at other generator models.

Noise level

Unfortunately, construction generators make a lot of noise. So much so that you'll probably want to protect your ears if you're going to be around the generator for a long time. However, the amount of noise they produce varies greatly from model to model. It partly depends on the power output, but some companies - like Yamaha and Honda - produce motors that are generally quieter than those from other manufacturers.

Advice

Replace the oil after the first 25 hours of use, then every 50 hours thereafter. For commercial users, this may mean an oil change once a week.
If you must refuel the generator during the day, allow it to cool completely before adding fuel. It may take up to 30 minutes.
Don't let your generator run out of fuel while it's running, as this can damage the engine.
If you must use extension cords, make sure they are heavy enough to carry the current your tools need.

Conclusion

Our three favorite generators for a jobsite are the WEN DF475T, Champion Power Equipment 76533, and Westinghouse Outdoor Power Equipment WGen9500DF. The Westinghouse generator provides an enormous amount of peak power, making it an excellent choice for a wide variety of professional users

Additionally, the generator is relatively inexpensive and offers many features to improve ease of use. The DuroMax XP13000EH is one of the best generators on the list thanks to its 50 amp outlet, relatively long run time, and ground fault circuit interrupter (GFCI) that ensures safety. Although the DuroMax generator is not cheap, you can be sure that a genuine Honda engine will last for years.

Nonetheless, we think the Yamaha EF7200DE Yamaha generator is the best generator for a jobsite because it's small, but mighty. It can power a job site with up to 6,000 watts of power for an entire working day, something few generators can match.
