Do I Need a Portable or a Whole House Standby Generator?

Aug 15, 2023

In an increasingly electrified world, power outages have become more than inconvenient – they can disrupt daily routines, compromise safety, and hinder productivity.

Fortunately, generators have emerged as a reliable solution to keep the lights on and the essential appliances running during unexpected power gaps.

However, as the demand for backup power options rises, so does the variety of generator types available. Two popular options that individuals often contemplate are portable generators and whole-house standby generators.

In this article, we will help you determine whether a portable or a whole-house standby generator is the right choice for you.

Portable Generator

Just like the name implies, portable generators offer convenient mobility. Thanks to their compact sizes, you can easily transport them to various locations as power demands arise.

While portability is the biggest talking point with portable generators, these generators also encompass diverse models. The compact model, whisper-quiet inverter generators, and traditional open-frame designs exist.

These versatile units typically feature tank capacities ranging from 0.9 to 20 gallons. Most of them run on diesel, gasoline, propane, or natural gas for operation.

While these are the basic modes of operation in portable generators, innovation has introduced newer models with dual-fuel capabilities. These models seamlessly transition between gasoline and propane fuel sources for operation.

However, not all generators labeled “portable” truly embody portability. Some exceed 150 pounds and are, therefore, bulky.

Regardless, these types of generators can achieve true portability through design elements like sizable wheels and robust handles.

Whole House Standby Generator

Whole House Standby Generators are also known as fixed or standby generators. They offer a permanent power solution by being installed outdoors and can activate themselves automatically during power outages.

They can integrate with your home’s natural gas or liquid propane system. So they eliminate the need for extension cords or gasoline refueling.

These generators serve as reliable powerhouses thanks to their incredible power capacity. Generally, standby generators usually have a power capacity spanning 8 to over 100 kilowatts.

In addition to their immense power, they are often designed with weather-resistant features, such as insulated covers. Hence, they are capable of withstanding the elements.

You can continuously use them outdoors, even in varying conditions.

Regarding fuel sources, standby generators efficiently run on diesel, propane, or supplied natural gas. Their automatic startup facilitated by a transfer switch positions them as ideal solutions for entities necessitating uninterrupted power.

In times of uncertainty, these standby generators emerge as the epitome of dependable backup power sources. They seamlessly bridge the gap when the grid falters.

Portable Vs. Whole House Standby Generator: Key Things To Consider

  1. Power output

When deciding between a Portable and a Whole House Standby Generator, begin by itemizing your essential appliances and calculating their energy demands.

Most devices often need a certain wattage for boot-up and operation. Such devices will require your generator to be capable enough, especially during extended use.

Take, for instance, consumer electronics like refrigerators (2400W startup, running) and washing machines (2600W). These electronics emphasize the need for a generator with enough power output.

Portable generators peak around 15,000 watts, so most aren’t capable enough to power the simultaneous use of high-demand items like AC units or heaters.

In contrast, standby generators offer large power outputs ranging from 10 to 50 kilowatts. This makes them capable of supporting an entire household’s electronics.

If you are particular about power output, the standby generator will be your right choice.

  1. Fuel efficiency

Fuel efficiency is a big determinant in the portable vs. whole house standby generator debate. Portable generators predominantly rely on gasoline, with few models utilizing diesel or propane.

Notably, a 6500-watt portable generator consumes approximately 18 gallons of fuel daily at half its capacity. This is equivalent to two standard 15-amp household outlets.

However, purchasing gasoline during outages can be stressful. You will need substantial fuel storage, which local regulations might constrain.

In contrast, standby generators tap into your existing natural gas or propane. Note that natural gas ensures prolonged operation, while propane offers the convenience of a simple refill.

Moreover, propane burns cleaner and emits fewer emissions than gasoline.

The outcome is clear: Standby generators emerge as the better choice for fuel efficiency. It delivers sustained power with minimized environmental impact.

  1. Versatility

Versatility is another important aspect when deliberating between portable and standby generators.

It is noteworthy that portable generators excel in adaptability. They seamlessly transition from homes to RVs and open spaces.

In addition, they can power various activities such as mowing lawns, charging devices, or grilling outdoors. Even larger models offer mobility since they have wheels for effortless transportation.

In contrast, standby generators permanently stay wherever they’ve been installed. While they ensure steadfast backup power, their application scope remains fixed.

The crown of versatility sits firmly upon portable generators since they offer dynamic energy solutions tailored to diverse settings and activities.

  1. Safety

Portable units emit carbon monoxide, so it is advisable to keep them outdoors to prevent fatal exposure. Although standby generators are also installed outside, they do not emit carbon monoxide as much as portable generators.

In terms of safety features, portable generators offer safety features like overload protection and low oil shutdown. On the other hand, standby generators do not offer as many safety features as portable generators.

That being said, the debate is a bit tied here.

Conclusion

In conclusion, choosing between portable and whole-house standby generators hinges on several vital considerations. While portability and versatility lean in favor of portables, the unmatched power, efficiency, and safety offered by Standby Generators are undeniable.
