  • 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 the 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.

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 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 in 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 the 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 needs to be powered.

Note this, before making a connection, it disconnects the utility line to prevent the 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 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 the power management feature to supply the 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.
  • 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 the portable generator, 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 heavyweight, 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 with the existing propane or natural gas supply to your house, and it will be ready anytime you want it to work. Related Articles:. 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 the 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 of which 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. 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 is the fuel that is conveniently available at 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 due to which 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 to pass the EPA standards and get approval.

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.

Fuel Options for Standby Generators

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, and it burns really clean compared to conventional fuels and releases very less harmful emissions in 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, where the faster kick in time is not so important because it may create some interruptions while starting during an outage. 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 use 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 in the same type of engine used for automotive purposes.

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 in the environment.

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

This is why this type of generator can easily meet the EPA standards and can be easily used in any state.
