How to Choose a Caterpillar Generator

If you go online and search for Caterpillar generators, you will find a lot of options. To help you narrow down the possibilities, below are the most important considerations.

Types of Generators

To start, you need to be familiar with the different types of generators available. This will help you easily narrow down the possibilities depending on your needs and preferences.

Portable Generators : The five products that are mentioned in this article all belong to this category. They are compact and lightweight, meant to be moved around depending on where you want to use them. These are also perfect choices in the campsite or in an RV.

Standby Generator : This is larger and more powerful compared to a portable generator. As the name implies, it is on stand-by and will automatically turn on when the power supply is cut.

Inverter Generator : Compared to other generators, it is quieter. It is also more expensive compared to portable generators. It is a good choice if you want fewer emissions and better fuel efficiency.

Size and Weight

If you are buying a portable generator, then go for one that is compact and lightweight. This way, it will be easy to bring it anywhere you go, such as when you are camping or anywhere else you need a temporary power supply.

Some may be large and heavy, but they are still considered portable because of their design. A common feature would be rubber wheels. This way, the generator can roll smoothly when you need to move it around instead of lifting it.

Power Requirements

As you try to trim down the possibilities, you should also consider your power needs or requirements.

The most important figure that you should understand is the wattage. Small generators can deliver 500 to 3,000 watts. Larger and more powerful generators, on the other hand, will deliver power of up to 10,000 watts.

To compute your power requirements, start listing the devices that you need to power through the generator. Know their individual watts an add them up. Next, there are two concepts that you need to understand. Starting watts refer to the power needed for the appliances to start. Rated watts or running watts, on the other hand, refer to the energy requirement for the appliances to function after the start-up. Both of these should match the power that the generator can deliver.

Fuel Type

The choice of fuel is important in Caterpillar generators because it will be indicative of the overall performance. It also affects the cost of long-term ownership, maintenance, and eco-friendliness.

Most of the Caterpillar generators will run on gas. These generators have a small tank, which also means that there will be a short runtime. While it is an accessible fuel, take note that it is highly-combustible, which can make it unsafe. In the long run, this can also be expensive because of the high cost of gas.

If you are looking for a more affordable alternative, then you can go with diesel. Although, this is not as popular as gas. One of the good things about diesel is that it is the least flammable fuel source, which makes it safe. However, the shelf life is limited without additives. It can also be noisier compared to the generators that run on gas.

Tank Size

Aside from the type of fuel, you also need to consider the size of the fuel tank. This is important because it determines how many gallons of fuel can be filled at a time. Especially if you will be camping or you will be anywhere there is no easy access to fuel, you will benefit from having a large tank without compromising portability.

Runtime

The size of the fuel tank will have an impact on the runtime of the generator. The latter refers to the number of hours by which the generator can operate continuously. In the case of the Caterpillar generators, which is also the practice amongst other manufacturers, the runtime stated is based on a 50% load capacity. The higher the load is, the shorter the runtime will be.

Noise

It can be annoying if the generator makes a lot of noise. Especially if you will be using your Caterpillar generator in the campsite, look for the quietest model available. Many parks will have rules when it comes to the maximum noise output of the generator. This will also prevent you from disturbing others who are enjoying their time in the campsite.

Start-Up

Another important consideration would be how you will be starting the generator. This is going to affect its ease of use. Traditionally, generators have a pull/recoil start method. This involves having the need to pull a string until the engine successfully starts. Today, we have more modern models with an electric start feature. The generator will start within seconds by activating the switch.

Display

A common feature that you will find in Caterpillar generators is the display. It is often in the form of an LED screen. It has a backlight, which means that it will be easy to read whether it is day or night. The latter will display the important information you need to know, such as the total runtime. It can also show how much fuel is remaining so that you can refill the tank immediately.

Durability

Caterpillar generators can be expensive! For the best value for the money, make sure to choose a model that comes with a durable construction. An all-steel body is great. This might make the generator heavy, but this will also have a positive impact on its longevity. To be durable, it will also good to have rubber covers for the plugs, which will protect against dust and dirt.

Safety Tips when Using Caterpillar Generators

Caterpillar takes pride in having innovative products with state-of-the-art safety features. As the owner, however, you are still largely responsible to ensure safe use.

Here are some tips to keep in mind:

• Run the generator in an open and well-ventilated area. Never run the generator when you are indoors. It emits carbon dioxide, which is a toxic gas. It also has a foul smell that many people will find bothersome.

• Do not leave a portable generator open in the rain. If you are camping, you can buy tents especially made for generators, which will have a canopy but will leave a lot of open spaces for proper ventilation.

• If you need to re-fuel the generator, turn it off first. Also, let it cool a few minutes before filling the tank. Be careful not to make splashes. It can result in ignition, and in turn, will be a fire hazard.

• It would be best to plug the appliances directly to the generator. If you have to use an extension cord, make sure that it is heavy-duty and that it meets the power requirements of the generator.

• Pay attention to the load capacity of the generator. You should never overload the generator as this can be a safety issue

• Always read the instructions from the manufacturer. Different models may have different operating requirements.Follow religiously whatever is stated in the manual.

Conclusion

Whether it is charging your gadgets at home or powering a fan in the campsite, among other applications, a portable generator is a lifesaver! While there are countless brands available, Caterpillar is one of the names that will be hard to match.So, if you are looking for the best Caterpillar generators, take note of our recommendations above. They are portable but pack a lot of power. You can be confident that they will be dependable wherever you are!

While it is decent for most appliances, however, take note that it isn’t for power-intensive applications. If you have demanding requirements, then we suggest that you choose a more powerful generator.

5,500 Running Watts

Looking at the technical specifications, this portable generator has 5,500 running watts and 6,875 starting watts. According to the manufacturer, it can provide power for up to 15 hours before there will be a need for refueling. This runtime is at a 50% load. It can power most small appliances.

5. Cat INV2000  Inverter Generator

This is the cheapest and most portable of the products that are mentioned in this buying guide. That also means that it is the least powerful. Some users were quite disappointed with how the power might end up being underwhelming, so take note that this isn’t ideal for heavy applications.

If you need more power than what it can deliver, then you can connect it to another inverter generator, provided that the technical specifications are compatible. Connect two generators to double the power output.

79.7cc OHV 4-stroke Engine

To be honest, this is the least powerful of the five models that are included in this review. So, choose this only if you need a generator that you can use for light-duty applications. Given its output, it is only good for a mini fridge, laptop, TV, and small power tools. If you have power-hungry appliances, then you will be disappointed with the performance of this generator.
