Factors to Consider When Buying a Caterpillar Generator

Power Output

The power output in watts is the most crucial consideration when buying a generator. Most generators have both starting and running wattage on their specifications list. The starting watt is usually more than the running watt, but you need not worry about that. To calculate the total power output in watts, look at all the appliances you want to use when the Generator is running. Add up the wattage of each device and then add 20% more which you can use to factor in power fluctuations or surges. It would be best to compare the resulting figure with what your potential Generator offers before making a purchase.

Type of Fuel

Gas-powered generators are the most common type on the market, and they are very convenient. However, they produce highly flammable fumes. Therefore, you should use them in well-ventilated areas. When buying a gas generator, it’s a good idea to go for one with an automatic shut-off feature that turns the Generator off when the oil level is low.

Diesel generators are less common, but they offer some advantages. They are more fuel-efficient than gas generators and can run for extended periods on a single tank. They have fewer maintenance requirements compared to gasoline models. However, they produce more noise than gas generators.

You can use either fuel source for home or industrial purposes, making them very versatile.


A generator’s runtime is the total amount of time the Generator can run on a single tank. Most of the time, the runtime is quoted in hours at 25% or 50% load. You can find this information on the specification list of most generators. A generator with a long runtime will save you from having to refuel often.


If you need to move your Generator around frequently, you’ll want a portable one. Most generators range from 40-250 lbs. but some models can weigh as much as 500-600 lbs. Cat INV2000 is the lightest portable generator weighing 49 pounds in our post. Heavy portable generators come with wheels and handles that make it easy to move them around on job sites or other applications where portability is a priority.

Noise Level

where are caterpillar generators made?Most gas-powered generators are noisy, especially those rated at above 5000 watts. However, you can go for a model with a noise-canceling feature that will reduce the noise level significantly.


The price of generators varies depending on the wattage, type of fuel, and other features. It’s essential to set your budget before you start shopping to avoid getting overwhelmed by all the options available.


Generators come with various warranties, depending on the brand and model. Most generators have a one-year warranty on parts, but some offer more extended warranties. A lifetime warranty usually covers the engine.

When shopping for a Caterpillar generator, it’s important to consider the factors above. The power output, type of fuel, and portability are the most important considerations, but you should also pay attention to the noise level and warranty. With these factors in mind, you’re sure to find the perfect Caterpillar generator for your needs.
