Construction site generators, providing reliable power solutions for construction projects, including powering tools, equipment, and temporary facilities

What size generator do I need for a construction site?

Those looking for a construction site generator need to take a step back to understand just how big the construction site will be to start off. Only then can a proper assessment be made of what type of generator will work best. And only then will you be able to know what are the best construction site generators for your specific needs. 

What to look for so you know what size generator to get 

First, don’t pay attention to the price; pay attention to the amount of power you will need. If the construction job is a small one, then you can opt-in for small construction site generators. These tend to be portable options and will naturally be on the lower end when it comes to costs. They’re a great option for those general contractors who tend to do residential-style work or small parts of commercial work. 

Choosing the Right Generator Size for Your Power Needs

Keep in mind that while they are portable, they will only be able to power so much. From there, look at the amount of tools you will be using that will require power. For example, you may ask yourself, what size generator do I need to run a hammer drill? Again, it depends on the size of the hammer drill! A small one may be fine with just 1 kW powering generators, while a large option can need up to 2 kW of power to function properly or even at all. 

Understanding Voltage Options: Preserving Equipment and Optimising Electricity Usage

Make sure you understand the voltage options as you want to preserve your equipment and not use too much electricity if it’s not necessary. Many of our options will have a 110v (recommended) and 220v option, such as this one, which is one of the best choices when it comes to pricing as well. If you have specialized equipment that needs a minimum of 115v and goes up to 230v, we also have you covered. 

What size generator do I need for a large building? 

Your wattage needs can go all the way up to a couple of hundred kW in some cases. Some are even more if you’re looking at areas that require intensive power usage such as hospitals or data centres. Our construction site generators for sale will be able to accommodate many different-sized projects, and we can also help provide options for those larger construction jobs as well.
