Did you know that Generac is a leading manufacturer of standby generators and has over 70% of the market share? With Generac, you are spoiled for choices. Different electrical and physical configurations of generators are available for various applications. 

It is hardly surprising that demand for electric generators has increased over the years. People all across the globe are spending money on the sense of safety that generators offer in times of blackouts, extreme weather, infrastructure concerns, and other issues affecting the electrical grid. However, selecting the ideal industrial generator might be difficult, given the numerous factors that need to be considered. Here, we bring you a comprehensive buying guide for one of the top generator brands- Generac.

About Generac

Having been established in 1959, Generac stands as the top producer of industrial backup generators, offering its clients superior comfort and peace of mind in times of need. Empowered to power a smarter future, Generac is a leading energy technology firm offering solar energy storage systems and backup power solutions for businesses. 

Generators can be powered by natural gas lines or liquid propane (LP). The standby generator waits for the signal to go on, much like an air conditioning unit does. A backup generator begins operating automatically, as opposed to a portable generator. All you need to do, then, is sit back and wait for your machines to power back in case the power goes out.

Understanding Power Requirements for Your Business

Industrial real estate has a wide range of electricity needs, especially depending on how the property is used. For example, more power would probably be required by a large auto manufacturing factory than by a smaller distribution center. 

Your Power Requirements

When selecting an industrial generator, one of the most important things to consider is the wattage or power capacity that your company needs. Industrial-size generators are available in a variety of power outputs, ranging from tiny units that can run a few necessary lights to massive units that can run a complete building. In order to be sure that the generator you select can supply enough power for your business activities, it is imperative that you understand your power needs. 

Voltage and Wattage

Measured in volts (V), voltage is the force that forces electricity through wires. The term “wattage” describes the amount of electricity or power that a gadget consumes when it is plugged in. Generators can power devices with lower wattages than their rating if you’re careful about how many of them run at once. Generators are rated by their wattage capacity, which allows you to see how much power they’ll create when running at maximum speed.

Type of Transfer Switch

Emergency standby systems mostly use automatically controlled transfer switches. You should decide on the transfer switch’s size (amperage rating) and position of installation position.  The transfer switch needs to be service entry rated, that includes a disconnect mechanism inside the transfer switch cabinet if the system is quite large enough to support the entire building. There are a few more transfer switch capabilities available for commercial and industrial applications, including the likes of closed transition, programmed transition, and bypass isolation.

Size of Generator

Choosing the appropriate size for the generator is very important as it may lead to lots of electrical issues. If you choose a large generator, then you may face an ineffective generation of power, additional operating costs, and, ultimately, harm to electrical systems. If your generator is small, it can lead to overheating, inadequate or inconsistent power, and failures of vital infrastructure and security systems.

Types of Generac Generators

The various types of Generac generators based on the fuel type used in them are:

  • Diesel Generators

Diesel generators are highly practical devices that burn diesel fuel to generate power. These devices produce electricity by combining a diesel engine and an electric generator. Diesel generators use combustion to transform some of the chemical energy that diesel fuel contains into mechanical energy. Tanks on diesel generators supply fuel to the internal combustion engine, which powers the generator and produces energy. They usually have greater starting expenditures and lesser fuel storage capacities than natural gas generators. With their fuel reservoirs, they function independently and guarantee a steady supply of electricity regardless of the state of the grid.

  • Natural Gas Generators

Generators use natural gas as their fuel work by burning the fuel to produce electricity. Natural gas is similar to gasoline and diesel, but it is more efficient than oil and emits about one-third of the carbon dioxide that coal does. Their engine first compresses natural gas and air, which are subsequently ignited. The explosion that follows drives a turbine that is attached to an alternator and eventually produces power. 

  • Propane Gas Generators

One fuel that individuals frequently use to power their generators is propane, a kind of liquefied petroleum gas (LPG). Different sizes of propane gas generators are available to meet different purposes. Usually, they’re close to a carport or other comparable space. Their fuel source is the propane storage tank. After a power outage, these generators turn on automatically in a matter of seconds.

Key Features To Consider When Buying Generac Generators

Power Requirements

It’s critical to comprehend your power requirements. Ensure that, in case of a power outage, the generator will power the whole building or simply the essential equipment.  Generac Generators offer utility-grade power for delicate devices and appliances that operate smoothly and cleanly with less than 5% total harmonic distortion. It also has a wide variety of generators with varying power output. Make sure you purchase the right generator for your needs because you cannot extend the power that generators provide. 

Fuel Type

Determine which fuel to use: propane, natural gas, or diesel, depending on availability, price, and convenience. While diesel generators have benefits such as on-site fuel availability, businesses may find that natural gas or propane is a better option, depending on facility requirements and accessibility. Generac Generators come in various fuel options for you to choose from according to your requirements.


Generator dependability depends on proper maintenance services. Selecting a trustworthy service provider for routine maintenance is essential to preventing unanticipated malfunctions during blackouts. The necessity of proactive servicing is highlighted by the fact that skipping maintenance can result in expensive repairs and downtime. You anticipate that a generator you purchase will last for however long it takes. Generac generators are designed to withstand the extreme strain that continuous operation can place on an engine. These generators become weather- and corrosion-resistant when coated with RhinoCoatTM powder.

Environmental Considerations

Choose fuel-efficient generators that can produce the necessary amount of electricity with reduced fuel use. Energy-efficient models cut greenhouse gas emissions and waste. Generac generators are especially quiet and use less fuel because they run for five or twelve minutes at a lower RPM. With the multilingual LCD of the Generac EvolutionTM Controller, you can keep track of maintenance schedules and battery state to make sure your generator is constantly operating at peak efficiency.
