The lights flicker, communications go down, productivity comes to a screeching halt, millions of dollars in goods are put at risk... The list is endless, but it all adds up to one thing -- lost profits.

Risking the failure of your business on something so sure as a power outage is a risk you and your shareholders cannot afford.

Why Your Business Can't Afford a Power Failure
If your company has ever experienced an outage, no matter how brief, then you know how quickly things can go awry. Aside from electric bills, operating expenses don’t stop because the meter stopped. Having a backup generator can be the difference between a profitable and unprofitable business in any given fiscal year, but will pay for itself in just a single power outage.

A commercial standby generator will keep the revenue flowing, the customers happy and the employees safe during a power disruption.


How Does a Commerical Standby Generator Work?
A generator that's built for commercial applications is going to be more substantial than a consumer model. The steel will be a thicker gauge, the engine larger and typically liquid-cooled, and the internal electronics more robust to handle higher wattages and higher heat associated with longer run times.



Select a Style
Commercial-grade generators are custom built based on your needs, so it’s important to select the right voltage.

While the utility power coming into your house is “single-phase” and powers 120/240 volt household appliances, the utility power for your business typically is 3-phase which supports a larger electrical demand.

How do you tell? Take a look at your main electrical panel. Your electrical panel will help you determine your voltage requirements.For many facilities, the electricity enters a building at 120/208 or 277/480 volts into the first electrical panel.

A step-down transformer can convert the incoming utility voltage into 120/240 or 120/208 volts. A second electrical panel will distribute the electricity throughout the office area.

Your best bet is to purchase a generator that matches the incoming utility voltage. This way, you can restore power to both electrical panels.


Commercial GeneratorsSingle-Phase
Smaller businesses, like homes, may only require a single-phase generator. These generators produce 240 volts, matching what the utility company supplies. Single-phase generators are used for most small businesses since they only need to power basic electronics instead of machinery.

Pick the Perfect Voltage FirstThree-Phase
Whether your business needs a single-phase generator or a three-phase generator depends on what you are getting from the utility company. Large manufacturing companies, farms, and other businesses like these may require three-phase power for special 3-phase equipment.
