Stationary Generator  Benefits

Leader in Affordable Business Standby Generators

Why Businesses Need a Stationary Generator

There are many reasons why a business needs a stationary generator.  The bottom line is, when power gets knocked out during a storm, you want to stay open.  A Generac generator can help you.  There are a number of reasons a business might consider backup power and things that are important to them.  These include:

-  Asset Security

-  Emergency Power

-  Employee Safety

-  Fuel Type for Business Backup

-  Natural Disaster Backup Power

-  Standby Power Gives You RIO

What is backup power worth to a business?  Every hour without power is an hour without sales.  Some types of businesses could recoup the cost of a generator in less than a day!

Generac Industrial Generators

Traditionally, business standby generators ran on diesel and were expensive.  Generac pioneered the development of clean, afforable propane and gaseous commercial generators.  With units readily available in single and three phase voltage, propane or propane vapor and gaseous or dry fuel, there's no longer a reason for business to operate unprotected from the dangers and costs of a power outage.

Keep Your Power On and Keep Revenue Flowing

Generac's business standby generators run quietly, stand up to severe weather and provide built-in functionality, making generator ownership easy.

A Wide Range of Options

You can also field covert any unity 48kW or lower from natural gas to propane. Models with special catalysts are available to meet the emission standards in California.
