Generator Buyer's Guide : Useful Information on Everything Commercial Generators

How Do I Choose the Right Size Commercial Generator?


The most important factors in figuring out which type generator is best for your business are where it will be used and what it will be used for. Does it need to be able to be moved? Asking yourself these questions will help narrow down your options. The next most important factor is sizing your generator. Too few watts and you risk overheating the generator and ruining anything hooked up to it, and too many watts will cost more money than you need to spend.


Determining Wattage Requirements. You will need to decide what equipment and/or machinery you will want the generator to power. You will also need the startup requirements for each piece of equipment, as machinery that has a motor or compressor (like an air conditioning unit), requires more power to start up than they do to continue running (as much as three times more).The most accurate way to do this is have an electrician do the measuring for you. This way you can be sure it’s done right, and more importantly, done safely.


What Size Generator to Buy. Once you (or your electrician) have figured out the requirements for your desired machinery and equipment, you’ll know what size generator to look at. It’s a good idea to add about 20% to your number to avoid overloading your generator and give you room to add to its load in the future.
