Natural gas is the most popular fuel source to the standby generators. As we know natural gas tends to be inexpensive. It doesn't create any poisonous reaction to the air and environment. If you have already a natural gas line stored on your home, then you just have to create among the generator fuel tank and gas line.

4.

Diesel

Diesel is more energy efficient than gasoline. They are prone to produce compression heating. So, they long last better than gasoline and endure less mechanical stress. Diesel is better and safer than natural gas and gasoline.

5.

Bi-Fuel Systems

We can apply a procedure to supply power to utility failure using two kinds of fuels at the same time. This is more effective and reliable to work simultaneously.


A dual system is flexible for using natural gas or LP vapor following their availability. In this case, the generator will start on natural gas first, but it will get support from the LP vapor if the gas flow is interrupted somehow.


If the generator has a very big unit, then you can make configuration of natural gas and diesel for the Bi-fuel generator burn both of them. This generator starts the engine using diesel and then it slowly reaches to natural gas fuel when the diesel is almost at its end point.


You can keep the consistency 25% diesel fuel and 75% natural gas. So, the Bi-fuel process will work like a pro.

A whole house generator has mainly two parts. One of them is the generator unit and the other one is an automatic transfer switch.

These two functionalities work to give power to the home whenever the electricity failure happens.

You will need help from the professional to install the transfer switch into the standby generator in a perfect combination connecting to the home’s overall existing wiring. So, the transfer switch works automatically whenever it can sense there is no power flowing in the home system.

So, when the power cuts off, the automatic transfer switch moves all the selected appliances with the generator and flow immediate support to the whole home system.

And the generator gets off automatically when the power returns. The transfer switch connects to the utility power and makes the generator shut down and reconnect it to the generator whenever it is required.

So, give your neighbor a reason to get jealous! Actually, installing a standby generator doesn't let you experience sweat in the summer and cold in the winter. You can always get your AC and heater turn on even your neighborhood is suffering from the power cut off.

Disadvantage:

Portable V/S Standby: Which One Is The Best?

In your region, if you face frequent power off, then you can invest in portable or standby generators. But, the query is to find out which one is to install in your home, right?

So, we are going to guide you to decide.

Portable Generators

Portable generators are handy in terms of easy to move and cheap price. There are mainly two types of portable generators. Electric and fuel types are great for reducing the power off hassle.

You can choose electric ones if you know that you are going to need the generator for short term tasks. To run the portable generators, you must need natural gas, biogas, propane, and diesel.

Portable generator fails to provide service to the power off as standby generators can do. So, they are not reliable like standby generators. But they offer the ultimate life support for 10,000 to 25,000 hours. It does actually depend on the care of the unit.

Standby Generators

Standby generators are not moveable. Once you install them somewhere you can’t move them. So, they are fixed for use after setup. They require maintenance and setup from professional and permission to install in the business and residential areas.

They are also like portable generators for the electric and fuel gas options. Electric standby generators are generally connected to the electric service through the wire and provide power when necessary. And the fuel options are always connected to the gas tank. The tank capacity might be propane, natural gas, diesel, gasoline, or others.

Standby generators are powerful for supplying necessary wattage to a whole house, office, schools, hospital, restaurant, or any emergency place.

The only negative impact that the users have identified is its noise. Some standby generators produce noise in the high range which is not really appreciated by anyone. So, when you are buying a standby generator for your home, you can check out the sound dampening system.

Air Cooled V/s Liquid Cooled: Which One Is The Best?

You are here to only get about the home generator reviews. Reviews tell you about the feature but not the real functionality. As we know standby generators work by the air cooled or liquid cooled functionality.

So, this is a finite thing to know which one is better?

Air-cooled generators have built-in fans to pass out the heated air. Thus, the generator stays cool while the engine doesn't hold any heated air pressure. Most of the homeowners love to have the air-cooled generator for their good values. They are a great option for power outage.

Liquid cooled engines keep the water inside it. But this is a complex system that requires high maintenance where the air cooled is much easier, flexible, and power sufficient.
