Factors To Put Into Consideration When Buying A Generac Generator

Generac is well-known for making high-quality products that offer reliable service during an emergency.

Generac Generators are environmentally friendly because of their superior fuel efficiency, reducing carbon dioxide emissions. In addition, they’re also cost-effective.

There are many different types of Generac generators available, but not all models are created equal.

Here are several key factors to consider when buying a Generac generator:


Capacity and Wattage

First and foremost is the size and wattage of your generator. You want to make sure that it can provide enough power to run all your appliances at once.

A GP3000i model will be enough for most homes with five bedrooms or less, but consider other models if you need something bigger (or smaller) than that.

Choosing a generator big enough for your needs is essential but not too large to unnecessarily burden your finances and energy usage.

You need a large enough generator to provide power for your home, but not so large that it won’t fit in your garage or shed. A portable generator will give you more flexibility and is easier to install than larger models.

Power Output

The first thing you need is to understand how much power do you need during the regular operation of your business.

You need to make sure that your generator has enough power for your different needs. How many appliances and devices you want to run using your portable champion generator will determine this.

The more appliances and devices, the greater power output it will require from the generator. Generators with over 5000W are recommended for heavier appliances.

Maintenance Costs

While generators are designed to provide backup power during outages, they can also help reduce energy costs by running during off-peak hours.

That’s because most Generac models feature an Eco Mode switch that allows them to run several hours at a time without overheating or draining your wallet.

Frequency Of Use

This is probably the most crucial factor to consider. If you're only going to use your generator once or twice a year, then there is no need to pay for extra features that you will never use.

A simple 2000-3000W Generac Generator would be enough for you.

Ultimately, any portable power system will need to perform under a wide range of conditions and workloads.

This means that it must be durable enough to withstand extreme weather, powerful enough to run the equipment needed, flexible enough to power multiple items, and compact enough to be easy to transport.

Inverter Vs. Non-inverter Generators

There is a vast difference between an inverter generator and a standard generator. Inverter generators produce clean power with a frequency of 60 hertz instead of 50 hertz, which means they can be used on any electrical equipment without damaging it.

In addition, being lighter in weight than traditional models, inverter generators also consume less fuel for producing energy than the other types of generators available in the market today.

Running Watts (Surge Power) Vs. Continuous Watts

Surge Power is the number of watts that can be generated for a short period during an emergency. At the same time, Continuous Wattage indicates the amount of power that your unit can continuously generate.

It is important to note that most generators can switch from Surge Power to Continuous and vice versa.

Fuel Source

Generators can be powered by propane, natural gas, diesel fuel, or gasoline. It’s crucial to understand the fuel compatibility with your Generac generator.

This will ensure that you never run out of fuel while also having more flexibility regarding using your generator.

We recommend using generators with an electric start because it eliminates the need for pull-cords and reduces the risk of injury.

Fuel efficiency (generator run time per gallon)

The priority should be 'fuel efficiency because the cost of operating these machines can get high if they are not efficient enough.

Make sure you choose one with minimum fuel consumption (0.5 gallons per hour) and how long it takes to charge up if this is an essential factor for you.

Noise level

A quiet Generac generator with low noise will not disturb your peace when used, but it will still be powerful enough to do what you want.

This is especially important when using a portable generator in an urban setting where noise could become a problem at night when everyone is trying to sleep, such as in a park or campground with neighbors nearby.

Larger generators with 6000W and above are noisy but very reliable.

Weight Of The Generator (In Pounds)

The weight of a generator is usually measured in pounds, but it depends on the manufacturer. It is important to note that most portable generators weigh 100 pounds or less (when empty). The average weight ranges between 50 and 75 pounds.

If you want to buy a portable generator with wheels, look for one that weighs about 70 pounds at most; otherwise, it will be too challenging to move around.

 Standby vs. Portable

Generac generators are either standby or portable, and it depends on the location of usage. You will need standby backup power in case of a foreseen emergency at home.

If you live in areas with frequent power outages, getting a generic standby generator is essential. Campers and remote job sites require portable generators since they are portable.



Generac generators are an excellent option for anyone looking to purchase a home generator. When purchasing, consider the capacity of your generator in terms of how many watts it can produce.

This will help determine what appliances you can use and how much power you need when purchasing one.

Ultimately, these Generac generators are among the best options on the market, and we recommend buying a Generac generator if you're looking for a quality machine that will last for years to come.
