Any construction activity requires power to run all necessary equipment and tools. But, the grid may not be able to supply enough continuous power and, if your company is working remotely, grid supply might not even reach your site. In this case, you must look into purchasing a generator. 

Each job site will dictate what kind of generator you need, so it's important to evaluate your site. By identifying your site's needs, you can better match them to a generator with similar capabilities. Here are a few key factors to consider when purchasing a generator.

Power

The most important thing to consider when looking for a generator is how much power your job site will require to work effectively. Think through all of the tools you will be running off the generator and make a list. Then, check each tool's wattage to find the total amount of electricity your construction site will require to run. 

Keep in mind, however, that some tools or motors require more power to start than to run. To allow for error or a power surge, add 10 percent to the total sum calculated. The generator you choose must have a rated and maximum output high enough to support your site's required amount of power.

Quality

A quality generator must be able to withstand the everyday demands of a working construction site. This means a well-built generator must have a quality engine. Look for a company with a strong reputation for engine reliability as well as a strong warranty program. Additionally, look for a fuel-efficient engine. It will cost less to run and promote efficiency — you won't have to constantly refuel it to keep working. Consider a generator with automatic idle control to conserve even more fuel. 

An extensive control panel also indicates a well-made generator. Look for an hour meter to monitor maintenance checks and a voltage meter to determine the amount of power you're using. Count the outlets to ensure there are enough to adequately power all necessary equipment. Furthermore, make sure the gas tank is large enough that you won't have to continuously refuel. An automatic low-oil shutdown is another sign of a quality generator, as it will guard against engine damage. 

Noise

Some job sites are located in areas with strict noise limits. In this case, how loud your generator is allowed to be is a big factor in your decision. The industry-standard sound level on a generator is about 70 decibels heard at 23 feet. Most meet this standard, but some sites might have different regulations. Consider purchasing a generator with a muffler or built-in noise reduction.

Alternative Options

Recent advancements in technology have made it possible to work without a gas or diesel generator altogether, even if your site is off-grid. So, if you are looking for a quieter, cleaner option, there are alternatives.

Solar-powered generators, for instance, are both durable and powerful. With a full day's charge from the sun's rays, a solar-powered generator can easily provide light throughout the night. Battery storage capacity also provides light for inside jobs. These power sources also emit no pollution, smell or noise, so they're perfect for inside jobs and sites with strict noise regulations.  

If you are running a smaller operation, an inverter generator might be a good option as well. These small, portable generators recycle the power generated by equipment to keep running. Thus, they are a much cleaner option. They are also quieter than conventional generators because they run slower and steadier and are made with noise reduction in mind. 

As always, to determine which power source is best for you, consider your construction site and your required power. Only then can you make the best choice for the job at hand.
