We’ll never forget 9/11. But, do you remember 9/12 and 9/13?

Remember the eerie feeling of looking into bright blue skies and not seeing a single airplane?

The terrorists didn’t just bring down a few passenger planes. They bankrupted the airline industry.

Now, imagine if your cash register stopped ringing for two days because of a prolonged power outage.

Bankruptcy may be extreme, but 48 hours can be the difference between a profitable and unprofitable business.

Aside from your electric bill, your operating expenses don’t stop because your meter stopped. Your employees still expect their paychecks. Your bankers still demand their mortgage payment.

In the past, it was probably more cost effective to simply weather the power outage. Back then, standby generators weren't cheap.

Now, businesses are extremely reliant on electricity, and standby generators are more affordable than ever before. They can often pay for themselves 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.

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

The utility power into your house is “single-phase.” It powers all of your 120/240 volt household electronics and appliances.

The utility power into your business is typically “three-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.
