Generators are a necessity for most homes, as our society needs electricity to function. If we don’t have electricity in our house, we won’t be able to watch our latest TV shows, go on the internet, or even have access to AC or a portable heater.
That being said, generators will come in handy during power outages, specifically when we need to restart our electricity supply. Two of the most commonly used generators are portable and standby generators. They are the easiest to use and are widely available.
First, let us discuss generators more in detail, and then compare the portable vs standby generator.
What is a Generator?
A generator provides backup power in the case of a power outage. For example, most large corporations or hospitals have generators that keep the electricity flowing even if their primary electricity source has been compromised. Generators can also be used at a smaller scale to be a backup power source for family homes in case of a power outage.
Depending on the size of the entire home, you need to pick the right generator. The two main ones are portable and standby generators. Both work great, but some may require a standby generator, and others will do just fine with a portable generator.
Portable Vs Standby Generator: Which is the Best?
Portable and standby generators do the same job, providing electricity during a power outage. Still, the way they function is entirely different. So let’s talk about the two generators in more detail.
The portable generator is much less expensive than a standby generator, plus they run on diesel fuel, propane, or natural gas. A portable generator is connected to a manual transfer switch. It needs to be manually installed every time you use the generator, as it can’t withstand extreme weather conditions.
If you want to use a portable unit when there is a rainstorm or experiencing inclement weather. In that case, you must keep them outside due to the risk of carbon monoxide poisoning and protect your generator with covers.
Portable generators are also quite loud, and for some individuals, the noise can be annoying. Therefore, portable generators are ideal for occasional usage.
A standby generator or whole house generator is a much larger unit that is permanently installed by a professional. The standby generator starts working as a backup power soon as it notices an electricity shortage.
The great thin about the standby generator is that it can produce more power than the portable generator, which means it can supply power to the whole house without any problems.
Depending on the model, they usually run on propane or natural gas and can run for days while keeping the entire home functioning with electricity. They are much more expensive than a portable generator and have to be connected to an automatic transfer switch, but they have much more benefits.
Which one is better?
If we look at the statistics, then standby generators are much more efficient than portable generators. But it entirely depends on the person and their needs.
Should I Get a Portable Generator or Standby Generator?
The type of home generator you get will depend on the usage. For instance, if you only need a generator for a couple of hours every once in a while, then you can make do with portable inverter generators. However, suppose you need a generator to power a house for days at a time. In that case, you should consider the standby generator.
Most experts suggest getting a larger generator for most cases, especially if you have the money to get one. However, a standby generator is always a safe option because you will not have to worry about it breaking down under bad weather, getting exposed to carbon monoxide poisoning, or being too loud.
The standby generator starts by itself, unlike the portable generator where you have to connect it to the power source through a manual transfer switch.
For many reasons, some people opt for portable generators. Although it isn’t as secure or robust as the standby generator, it does get the job done. However, most people who get the portable generator are only looking to get it because it helps them meet the minimal electricity needs.
It does everything without spending a large amount of money on a generator or having it affixed permanently to their home.
Now, if you need a home generator that will stand the test of time and work without any hiccups, a standby generator with an automatic transfer switch is an excellent option for you. But if you need a generator for temporary power, and don’t want to spend a lot of money, then a portable generator can be a great option.
How Does a Standby Generator Work?
A standby generator needs about 13 to 50 gallons of propane or natural gas per day to work. A standby generator works by supplying power to the home circuit via an automatic transfer switch when it detects a loss in electricity.
Also, a standby generator can work for days or weeks without requiring a refuel. An automatic standby generator will do a weekly test to make sure the generator is working correctly.
In addition, the standby generator provides power to your home air conditioners and other appliances to make sure everything runs smoothly and without any hiccups.
Most apartment buildings need to have a standby generator with an automatic transfer switch as a safety measure to ensure there is no technical issue, especially when there are security cameras in the building.
The standby generator can work for more significant structures and provide power to more systems that a family home might have, such as technical security systems and more.
Now that you have a basic understanding of how a standby generator works, let’s talk about the top three standby generators.
