Generators – A General Guide


Electricity is the lifeblood of modern society, powering our homes, businesses, and industries. While we take it for granted most of the time, power outages can quickly remind us of our dependence on this invisible force.

Standby and portable generators are the unsung heroes that step in during these times of need, ensuring the lights stay on, the food stays cold, and critical systems keep running.

In this article, we’ll delve into the world of standby and portable generators, exploring their differences, applications, benefits, and how they’ve become indispensable companions in our daily lives.

Understanding the Generator Basics

Before we dive into the specifics, let’s grasp the fundamentals. Generators are devices that convert mechanical energy into electrical energy. They consist of an engine, which provides the mechanical power, and an alternator that converts it into electrical power. Standby and portable generators work on the same principle, but their application and design differ significantly.

Standby Generators: The Ultimate Power Assurance

  1. Application: Standby generators are permanent fixtures, designed to provide backup power for your home or business during extended outages. These units are installed outside your building and are wired directly into your electrical system.
  2. Capacity: They range from 7,000 to 150,000 watts, making them capable of powering your entire household, including critical appliances like refrigerators, air conditioners, and heating systems.
  3. Fuel Sources: Standby generators are often fueled by natural gas or propane, offering a continuous power source as long as your gas supply remains intact.
  4. Automatic Activation: Standby generators are equipped with an automatic transfer switch (ATS) that detects a power outage and starts the generator without manual intervention. This ensures uninterrupted power, making them an excellent choice for situations where even a momentary power loss can have severe consequences, such as in healthcare facilities or data centers.
  5. Noise Levels: These generators tend to be quieter than their portable counterparts, thanks to their sound-dampening enclosures.
  6. Cost: While more expensive to purchase and install initially, standby generators offer long-term reliability and convenience, ensuring your home or business remains functional during extended blackouts.

Portable Generators: Versatility On the Go

  1. Application: Portable generators are versatile and can be used for various purposes, including outdoor events, camping, construction sites, and temporary backup power during brief outages.
  2. Capacity: They come in a wide range of sizes, from small units that produce 1,000 to 4,000 watts to larger models with up to 10,000 watts, depending on your needs.
  3. Fuel Sources: Portable generators are typically powered by gasoline, propane, or diesel. This flexibility allows you to choose a fuel source based on availability and convenience.
  4. Manual Activation: Unlike standby generators, portable generators require manual activation. When a power outage occurs, you must start the generator, plug appliances or devices into it, and manage the fuel supply.
  5. Portability: Their name says it all. Portable generators are designed with mobility in mind. They often feature wheels and handles for easy transportation, making them suitable for a wide range of outdoor and emergency applications.
  6. Cost: Portable generators are usually more affordable compared to standby generators, but they offer a limited capacity and require manual operation.

Choosing the Right Generator for Your Needs

Selecting the right generator depends on your specific requirements, and understanding the differences between standby and portable generators is essential in making the best choice.

  1. Backup Power Needs: If you need a continuous power supply to maintain essential systems during extended power outages, a standby generator is the way to go. For occasional outages and versatile power needs, a portable generator might suffice.
  2. Mobility: If you require a power source on the go for various applications or during outdoor events, a portable generator is your best option due to its mobility. Standby generators are stationary and meant for permanent installations.
  3. Budget: Consider your budget. Portable generators are generally more budget-friendly upfront, but they require ongoing fuel and manual operation. Standby generators are a long-term investment with higher initial costs but provide automated, uninterrupted power.
  4. Fuel Source Availability: Evaluate the availability of fuel sources in your area. Standby generators commonly use natural gas or propane, while portable generators can run on gasoline, propane, or diesel. Choose a generator that aligns with your fuel source access.

Benefits of Standby and Portable Generators

Both standby and portable generators offer numerous benefits, making them invaluable in various situations:

Standby Generators:

  1. Reliability: They ensure continuous power, making them ideal for critical systems in healthcare, data centers, and residences.
  2. Convenience: Automatic activation means you don’t need to be present to restore power during an outage.
  3. Increased Home Value: A standby generator can add value to your property, making it a worthwhile investment.
  4. Peace of Mind: You’ll have the peace of mind knowing that your home or business won’t suffer due to power disruptions.

Portable Generators:

  1. Versatility: Portable generators can be used for a wide range of applications, from powering tools on construction sites to camping and outdoor events.
  2. Affordability: They are a cost-effective solution for temporary power needs and can be more budget-friendly than standby generators.
  3. Mobility: You can take them anywhere, ensuring a power source on the go, even in remote locations.
  4. Quick Response: Portable generators can be activated immediately, providing power when needed without delay.


In a world increasingly reliant on electricity, standby and portable generators provide essential lifelines during power outages. Standby generators offer seamless, automatic backup power for homes and businesses with critical systems, ensuring continuous functionality.

Portable generators, on the other hand, provide flexibility and mobility for various applications, making them versatile companions for outdoor adventures and temporary power needs.

Understanding the differences and benefits of each type of generator is key to making the right choice for your specific requirements.

Whether it’s the steady assurance of a standby generator or the adaptability of a portable one, these devices are vital tools that ensure the lights stay on, the warmth continues, and the machines keep running, even in the face of a power outage.
