What’s a
commercial generator?

A standby commercial generator keeps your power on and your business open during an outage. It’s installed outside your business (like an AC unit) and comes on automatically — whether you’re open or closed. All within seconds of a power outage.

Plus commercial generators run on propane or natural gas, so there’s no refueling.

Power It All

KOHLER generators can power your entire business. Take a look.

What’s an automatic transfer switch? (aka ATS)

Meet the brains behind your home generator system. The ATS is always monitoring your home’s power.

During an outage, it automatically transfers power from the utility to your generator. And when utility power is restored, the ATS turns off your generator and returns your home’s power to the utility grid. Pretty great, huh?

How much is this going to cost?

A standby commercial generator with installation typically starts at under $6,000. However, the total cost will vary based on your power and installation needs.
