What is a Standby Generator?

You can’t imagine your day without electricity in these modern days. If the power outage stays for a long, it might affect your work if you are working from home. It ends the entertainment from electronic devices and robs you of your comfort.

The power outage can be worse if it doesn’t go away for days or weeks. If you want to keep your day going without any, then the standby generator is a solid choice. You won’t even notice that there is a power outage.

A standby generator offers convenience, and you won’t have to connect and start it every time the power goes out and take it off when the power comes back.

They have installed devices on your premise that will automatically start powering your devices when the power goes out, and they will turn themselves off when the power comes back.

The transfer switch is the main component for proper automatic function. It detects the power and gives the signal to the generator whether it is time to start or shut off. And all these things happen in just a matter of seconds, and this makes them highly convenient.

How Do Standby Generators Work?

working of standby generator

A power outage is a common thing if you live in an area where there are frequent natural disasters like a tornado or a hurricane. The power will take a few days to weeks to get restored.

If after such kind of natural disaster power comes back in a day, then you are fortunate, and if it doesn’t, then you are not so, but you can be if you have a standby generator. They provide you with safety and peace of mind, but how do they work?

A standby generator is a device that will power all your appliances in the house, and it is permanently connected to the electrical circuits of your home through a transfer switch.

A generator simply has an engine that uses natural gas or propane, and sometimes for large power output diesel as a fuel to generate electricity.

When the engine generates the power, it gets hot, and to cool it down, a pump is provided to circulate the coolant through the engine, which will then flow into the radiator. A fan will blow the air over the radiator, releasing the heat outside and cooling the coolant.

The main component for a standby generator is a transfer switch, and it is a smart controller that does the coordination. When a power outage occurs the transfer switch senses the outage and gives the signal to the generator engine to start.

After giving it a few seconds to stabilize, the connection is made with the circuits of the house, which need to be powered. Note this, before making a connection, it disconnects the utility line to prevent problems arising due to back feeding.

The same goes for when the power returns, the transfer switch senses that the power has come back, it will disconnect the generator from the home and will connect the utility supply.

After giving some time to the generator for cooling down, it will be turned off. This cycle will repeat in every power outage condition.

Some sophisticated transfer switches in the market come with a power management feature to supply power only to priority circuits when the power goes out. If two power-consuming appliances are connected, then it will keep one waiting until its turn comes.

What is the Difference Between Standby Generator and a Portable Generator?

Portable generators and standby generators are significantly different from each other. One obvious difference resides in their name; a portable generator can be carried along wherever you require power, whether it is a campsite or a job site.

On the other hand, the standby generators are made to sit in one place, and they don’t have any handles or wheels to move them. They are hardwired to the electric circuits of the house.

A portable generator will be small and will have a small engine that can supply power for a brief period of time, and they are suitable to run only essentials during a power outage. The standby generator is designed to power for an extended period of time and can supply power to almost all house appliances.

Another difference is that you will have to manually turn on and turn off the portable generator when you need power, and they need to be regularly checked for any faults and need to be periodically maintained to ensure long life.

But if we talk about the standby generators, then because they are connected forever to the electrical circuits of the house, they sense the power condition on the utility line.

If the power goes out, then the standby generator automatically starts, and when it comes back, the generator will automatically shut off.

Moreover, automatic generators run the automatic test on them and notify the user if there is anything wrong with the system, so no manual checkup is required.

When it comes to portable generators, then they need to be run outside. If used inside, then the accumulation of the exhaust from these generators can turn out to be fatal if breathed in.

If they are outside, there is a risk of theft. But for the standby generators, due to their heavy weight, they don’t appeal to thieves much.

Other than that, if you want to run the portable generator as a backup generator, then you will have to first accumulate the fuel, and the fuel tends to evaporate.

This doesn’t always make it possible to have fresh fuel. While for the standby generator, you can directly connect them to the existing propane or natural gas supply to your house, and it will be ready anytime you want it to work.

What Size Standby Generator is Best for My House?

It is important to determine the size of a generator before making any decisions. If the generator can’t supply enough power, then a few of your appliances won’t start when you need them. If it is too large, then the initial investment and maintenance cost will be high.

The generator can be small or large, their price increases proportionally to their size and the features with which they are equipped.

If you only want to power the essentials during a power outage, then you can go for a small generator; it will be light on the pocket. Generally, the size of standby generators is defined by their power output rating in kilowatts.

If you want to get a fairly good idea about the size of the generator you are going to need, then first calculate the number of appliances you will be running with this generator in a power outage condition.

It can be a refrigerator, lights, a TV maybe, an oven, etc. Once you decide on the appliances you want to power up, keep the margin of 15% for future needs, and if such a need arises, then you can do so without any compromise on existing running appliances.

Once that is done, note down the wattage requirement of each appliance. You will mostly find it on the data label of the appliances. If not, and if the voltage and amperage are given, then by multiplying them, you will get the wattage.

After that, sum up all the wattage of each appliance that you chose to power in an outage.

Whatever the result of that summation is, the generator should have a minimum power rating to run all the appliances satisfactorily. When making a final decision, always choose a generator whose power rating is 25% more than your actual requirement. This will ensure reliability over the upcoming years to come.

If you live in a moderate-size house, then a generator of 20kW rating should satisfy your power needs. And for bigger houses, you can always go for the bigger-size generators.

Fuel Options for Standby Generators

standby generator

Different standby generators have different designs to run on different fuels. The main fuel choices available for standby generators are natural gas, diesel, propane, and bi-fuel. This makes them highly versatile to use for a variety of applications in various places.

Diesel

Diesel is the fuel that is conveniently available in every place, you can’t find liquid propane, but you can always find diesel. Besides, they are highly efficient and provide much power from a small quantity, and when the application is big, the cost-effectiveness can be seen.

Those are the two main reasons why you will find most of the standby generators on the market runs on diesel.

Diesel is easy to store and becomes extremely reliable in emergencies due to its fast kick-in time. The generator will start supplying power in no time, and that’s why you will find them as a backup at every hospital for critical applications.

But the limitation is you can’t store them for longer periods, so there will always be a need for extra measures to ensure a long lifetime. The main problem with the diesel standby generator is their high emissions in the exhaust; this gives them a hard time passing the EPA standards and getting approval.

Natural Gas

It is not that in just recent years, the attempt has been made to use natural gas as a fuel; in the past, there were many tries for that as well. But due to the limitations of the technology, it wasn’t that suitable to use it as a fuel compared to gasoline, and that’s why it was avoided. But with the recent development, it became possible to generate energy and that too efficiently.

The gaseous generators work the same as the liquid ones; a gas and mixture of air are burned to produce the power. The main advantage of natural gas is its low level of emission, it burns really clean compared to conventional fuels and releases very less harmful emissions into the environment.

Another thing that should be pointed out is that it is really cost-efficient, and it doesn’t need to be stored. You can connect the standby generator directly to the existing gas supply. This makes them highly reliable, whereas the faster kick-in time is not so important because it may create some interruptions while starting during an outage.

Propane

Another fuel that is used to power the standby generator is liquid propane which is also known as propane or butane. Propane is available in a liquid form in a compressed propane tank.

This makes it an alternative to using it on-site. The main benefit of using propane is that it won’t go bad even when 8 to 10 years have passed. This makes it a useful option in any situation. If there is a natural disaster, then you may not get your hand on diesel because all might have been sold, but if you have propane stored, then it will supply the power in an instant.

The generators which run on propane are generally small in size, and if you need a large generator, then they are costly to get and also to run. They run on the same type of engine used for automotive purposes.

Bi-fuel

There are generators in the market that work on two fuels. Note that these aren’t the standard unit type, and most of the manufacturers don’t even make them. This is the solution to problems that are faced when you use on-site fuel and utility fuel.

In certain situations, these generators are extremely helpful. Because you can switch between two fuels whenever you feel like it, or the need arises. Most dual-fuel generators can use either natural gas or diesel to produce power.

The ability to select the fuel equips you with higher flexibility; if one is not available, you can always use another.

Generally, not both fuels are simultaneously used to produce power, but in some generators, it is possible. And those types of generators are started with diesel as a primary fuel, and then gradually, propane is introduced until the most suitable mixture is achieved, which will be cost-effective and will release fewer emissions into the environment. This is why this type of generator can easily meet EPA standards and can be easily used in any state.

The discussion on different fuel types ends here, with this information you can select the generator which suits your needs based on the fuel availability and the ups and downs of individual fuels.

FAQs

Q. Where Should I Install a Standby Generator for Convenience?

You are not going to go near your generator unless it requires refueling or repair, so for that purpose, it should not be located in such a way that it doesn’t become a task to reach for refueling. It should be easy to access. The convenience can be increased if you place it near the fuel supply and the transfer switch and you will require a small cable for connection.

If you are planning to install it outside, then make sure you are properly following the code guidelines for minimum distance. Also, it should be out in such a way that exhaust can be easily released and it has enough airflow to cool down. And, also makes sure that it is kept a little higher than the earth on some support so that water can’t reach it.

Keep it in such a way that the noise coming out of it doesn’t disturb you or your neighbors.

Q. What Are the Installation and Permit Requirements for The Connection of the Standby Generator?

If you want to install the standby generator as a backup on your premises, then you will need a permit from the local building authority to commence the work without a permit, and if they catch wind of this, you will have to demolish all things.

Another thing is the standby generator needs to be placed on concrete for some local codes, but for some, it is not. It is good to have the generator placed on a block of concrete.

So, before you do anything, choose an installation location and then request a code inspector to assess and approve the installation. Once it is approved, you can start the installation without any worry. If all the regulations are properly followed, then in case of accidents, your insurance provider will also honor the policy.

Q. Which Type of Transfer Switch Should Be Used for A Standby Generator?

A transfer switch will be available in two types, manual or automatic. An automatic transfer switch will restore the power when the utility power goes out automatically without any kind of support from your side. While on the manual transfer switch, you will have to do the switching manually. Note that you won’t get the benefit of a low price when you go with the manual transfer switch.

A transfer switch also depends on the power output of your generator and the appliances it needs to power. If the whole house needs to be powered, then a transfer switch needed will be rated for the service entrance. It should be installed by a seasoned electrician who decided the location and size you will need. If the installation is for a commercial or industrial setting, then bypass isolation, closed transition, and the programmed transition type transfer switch is used.

Q. Do I Need an Electrician for The Installation of The System?

Yes, the installation should only be performed by a licensed electrician or a plumber because they know the system and have all the experience to do the job. This is highly risky if you do it yourself, and it poses a great danger to your equipment, generator, and people around you too. Or you can hire a reputed company to do the installation.
