What Are Common Myths About Standby Generators?

April 5, 2026

Quick Answer

Common myths about standby generators include their high upfront costs and the assumption that they are only suitable for large homes. These perceptions may be based on outdated information or incorrect assumptions about the technology. In reality, modern standby generators are more affordable and flexible than ever.

Higher Upfront Costs Are a Myth

Many people assume that standby generators are expensive, but the actual cost is often lower than anticipated. A typical whole-house standby generator system can cost anywhere from $10,000 to $30,000, depending on the size and features. However, when you factor in the long-term savings and benefits, the investment becomes more attractive. For example, a 20 kW generator that runs for 100 hours per year can save you around $2,000 in electricity costs annually.

Standby Generators Are Suitable for All Sizes of Homes

Another common myth is that standby generators are only suitable for large homes. However, the truth is that they can be designed to power any size of home, from small apartments to large estates. A 5 kW generator, for instance, can power a small to medium-sized home with a few bedrooms and appliances. When selecting a generator, it’s essential to determine your power needs based on your specific requirements.

Automatic Transfer Switches Make the Process Seamless

One of the most significant advantages of standby generators is their ability to automatically switch between grid power and generator power. This is made possible by an automatic transfer switch (ATS) that detects power outages and seamlessly transfers the load to the generator. A high-quality ATS can be programmed to perform self-tests, provide real-time monitoring, and even schedule maintenance reminders, ensuring that your generator runs smoothly and efficiently.
