Selecting The Right Generator For Your Farm: A 7-Step Guide

Last Updated on December 2, 2023 by Kimberly Crawford

In agriculture, reliable power is essential for ensuring the smooth operation of various equipment and maintaining the well-being of livestock. During power outages, a generator becomes a lifesaver, providing backup power to keep your farm running without interruption. However, choosing the right generator from the wide array of available generators can be daunting.

In this comprehensive guide, you’ll discover the knowledge and insights to make an informed decision and choose the generator that best suits your farm’s requirements:

Understand Your Power Needs

First, assess your power requirements. Consider the essential equipment on your farm. Do you have refrigeration units, heating systems, or other machinery that cannot afford to go offline?

Calculate the total wattage units like power generators require. This step is crucial as it ensures you’re not left underpowered or overspending on an unnecessarily large generator.

Fuel Source Consideration

When evaluating the fuel source for your generator, several key factors come into play:

  • Diesel Generators: Known for their efficiency and long lifespan. Diesel has a high energy density, offering more power per gallon than other fuels. However, storing diesel can be challenging, especially in colder climates where it can gel.
  • Gasoline Generators: These are more common and generally less expensive than diesel models. Gasoline is readily available but has a shorter shelf life and is highly flammable, requiring careful storage.
  • Propane Generators: Offer a long shelf life and cleaner emissions. It is a great choice if propane is already used on your farm. However, they might be less efficient in energy output compared to diesel.
  • Natural Gas Generators: Provide a clean and efficient power source with a lower environmental impact. It is convenient if connected to a natural gas line, but dependent on the availability of the gas supply, which can be a limitation in remote areas.

Each fuel type has unique considerations regarding availability, storage safety, and impact on the generator’s efficiency. Your choice should align with your farm’s logistical capabilities and operational needs, especially if you want to reduce gas consumption.

Assess The Power Output Quality

Power output quality is crucial, especially for running sensitive electronic equipment. Total Harmonic Distortion (THD) is a key factor. Opt for a generator with low THD, as high levels can damage equipment over time. Inverter generators generally offer the cleanest power.

Also, consider the generator’s voltage regulation capabilities. Stable voltage is essential for the safety and efficiency of your electrical devices. Poor voltage regulation can lead to fluctuating power levels, which can be harmful for delicate equipment.

Choose The Generator Type

There are various types of generators you can consider. Selecting the appropriate unit is critical in ensuring your farm’s energy needs are efficiently met. Here’s a breakdown of your choices:

  • Standby Generators: These are permanently installed and automatically activated during power outages. Ideal for large farms, they can power heavy machinery and are hardwired into your electrical system. They often run on natural gas or propane.
  • Portable Generators: Known for their mobility, these generators are perfect for smaller farms or specific tasks like powering tools in remote fields. They typically run on gasoline and are a more affordable option.
  • Dual-Fuel Generators: These generators can operate on more than one type of fuel, commonly gasoline and propane. They offer flexibility in fuel choice and availability, which can be particularly advantageous in situations where one type of fuel may be more accessible than another or during fuel shortages.
  • Inverter Generators: These are the most sophisticated, providing energy-efficient, clean power with minimal noise. They are excellent for electronics like computers or communication devices and are often used for smaller power needs.

Your choice depends on your farm’s size, the criticality of uninterrupted power, and the types of devices you need to operate. For example, a large farm with critical refrigeration needs might opt for a standby generator, while a smaller operation might find a portable or inverter generator more practical and cost-effective.

Installation And Maintenance

Consider the installation and maintenance needs of the generator. For instance, standby generators require professional installation and regular maintenance to ensure they are always ready to go.

This process often involves electrical and fuel hook-ups, and should be handled by certified technicians to adhere to safety standards and local regulations.

Additionally, maintenance is critical to longevity. Regular checks, including oil and filter changes, and inspections for wear and tear, ensure the generator remains in optimal condition.

Safety Features Are Key

Safety is a non-negotiable aspect when it comes to selecting a generator for your farm. Here are some essential safety features to look for:

  • Automatic CO2 Shut-Off: This feature detects harmful carbon monoxide levels and shuts down the generator to prevent dangerous exposure.
  • Overload Protection: It ensures that the generator automatically turns off if it’s overloaded, preventing damage to the generator and connected equipment.
  • Weatherproof Housing: Generators should have durable housing to withstand harsh weather conditions, protecting the internal components from damage.
  • Ground Fault Circuit Interrupter (GFCI): This feature prevents electric shock by shutting off the power if it detects an imbalance between incoming and outgoing current. It’s particularly important for portable generators used in outdoor or potentially wet environments, as it helps prevent electrical shock hazards.
  • Low Oil Shut-Off: This sensor automatically turns off the generator if the oil level is too low, preventing engine damage.

Incorporating these safety features can significantly reduce the risk of accidents and increase the longevity of your generator, ensuring a safer work environment on your farm.

Budget And Warranty Considerations

Balance your budget with the quality and features you need. Although it’s tempting to go for cheaper options, consider the longevity and reliability of the generator.

Besides, investing a bit more initially can often lead to lower costs over time, as higher-quality generators typically require fewer repairs and have a longer lifespan.

Furthermore, check the warranty and after-sales service options. Inquire about extended warranties or service plans that could offer extra peace of mind and potentially save money in the long run. A good warranty can save you from unforeseen expenses in the long run.


Choosing the right generator for your farm doesn’t have to be daunting. By understanding your power needs, selecting the right type, considering the fuel source, assessing power quality, focusing on safety, and balancing your budget with quality, you’re set to make an informed decision. So, power up your farm with the right generator and keep your operations running smoothly, no matter what comes your way.
