The 5 Best Generators for Home & Buying Guide (2020)

Never be separated from electricity, the source of our modern life

Are there frequent power outages where you live, and your work is always interrupted? Generators are ready to save you from this problem by keeping electricity in your home at all times.

Have you ever seen a view from space where the earth is at night?

What a fascinating sight, isn’t it? We owe this magnificent view to the electricity. Actually, most devices that make our daily life more comfortable and practical such as washing machines and dishwashers, refrigerators, ep phones, and computers, operate thanks to electricity. If you think a little bit, it can be terrifying to imagine a world without electricity.

This being the case, in the slightest power outage, all we do is interrupted, and troublesome situations may occur. People started to be interested in generators to get out of this situation. Considering this situation, we have prepared an article to learn what you should pay attention to when buying generators and get brief information about electricity; moreover, you can check some products we suggest.


Standby Generators

Whole house generators or similarly standby generators usually provide electrical power to feed your entire house. Power outputs can range from 9 kilowatts to about 50 kilowatts. The smaller ones use natural gas and liquid propane as fuel, but the larger ones also have a diesel option. Generally, they are used with the automatic transfer switch. It is connected to the electricity grid directly, and when the electricity goes out, it is activated automatically.

Portable Generators

They usually have a wheeled design, which makes them portable. It ranges in capacity from 1kw to 10kw. Mostly, it is not enough for the entire home, but it can power many tools and lights. It supplies temporary power and typically runs on gasoline. Portable Generators are more affordable compared to the others. Thanks to its portability, you can use these generators appropriately for every purpose.

Inverter Generators

Inverter generators are relatively new technology. Their size is small, and it is lightweight, as opposed to the other types. Since they adjust their operating speed according to the electricity needs, their fuel consumption and noise are less. It is more expensive than a different sort. Inverter generators are the best option for traveling.

Solar Generators

It takes power by sunlight energy, which is renewable and not harmful to nature. Whereas its output is less than the other generator, it is the safest option for backup power. It can be used interiors due to it has no emission.


Benjamin Harrison, the 23rd president of the United States, was the first president to use electrical energy in the White House. Still, he never touched any electrical switches because he was terrified of being caught in electricity.

#5 Best Start & Usefulness: Westinghouse Portable Generator

With the electric start switch, you can start the generator very quickly, or you connect it to an ATS, and it starts to work automatically, which makes it very useful.



Before buying a generator, one of the most critical factors you should determine is the generator’s capacity. You should evaluate the capacity of the generator according to your needs. Do you want to operate all the tools in your home or just certain appliances? Accordingly, you should make a list of the devices that use electricity and calculate the total electrical load.

Note that if there are old devices used for a long time (such as an 8-year washing machine) while calculating, they may consume a little more electricity than the label value.

Conventional light bulbs, electric heaters (kettle, electric stove, toaster) regularly consume as much electricity as the watt written on the label.

Devices containing motors (refrigerator, freezer, fan, electric motor), fluorescent lamps need two times the starting power of the label.

After making a list and calculating the total electricity consumption, we suggest you buy a generator which one-fourth more potent than your need, so you feel fewer performance drops. Moreover, when your required watt increases, the generator will operate in an uneventful manner.

We have compiled the amount of power required by some home appliances below. If there is a device you want to learn in particular, you can find out by searching on the internet in the way that “the power consumption of ……”

Fuel Type

1- Natural Gas

It is one of the most used fuels in generators. Since it is connected to the natural gas line that comes to your home, you will not have to buy and fill fuel frequently. It is also inexpensive compared to other fuels and burns efficiently. Make sure you have a natural gas network connected to your home.

2- Liquid Propane

Propane is a prevalent fuel used in generators. It has a longer life than other fuel types, so it does not cause performance loss in the generator. It is a little quieter than the others. In freezing weather, it cannot provide the necessary power to the generator.

3- Gasoline

Gasoline is widely available, so it is effortless to obtain. Shelf life is an average of 20 weeks. However, with fuel stabilizers, its structure can remain intact for years. They are mostly preferred for portable generators.

4- Diesel

Its non-flammability makes diesel fuel safer than gasoline and natural gas. It is the most efficient fuel per gallon. It has a life of up to 52 weeks without using a fuel stabilizer. It generally provides efficiency in situations of longer duration (when generators run longer). It is mostly preferred for whole-house generators.

Portable or Standby?

One of the most crucial features that distinguish the two is that whereas the standby models are mounted in a specific place, the portable generator does not need to be positioned in a particular area. Compared to the whole-house generators, portable ones do not require a professional person for installation. Hence, it means there are no costs for the buildings and preparations.

Portable generators may not be powerful enough for your whole home. Although there are those with very high power output, they generally provide up to 10kw of power. For example, if your home appliances also have an air conditioner, portable generators will not satisfy you. However, the power of whole household generators can be up to 50 kilowatts, depending on the model. These numbers mean a level of energy that is enough even for a home with many devices. You can operate your washing machine very comfortably while using your air conditioner at the same time. Moreover, most portable ones work with gasoline, while the whole house generator has LPG, natural gas, and diesel fuel options.

Switch Type

If you want the generator to be activated automatically when the electricity goes out, you must buy an Automatic Transfer Switch (ATC). When the electric grid is cut, it activates the generator switch and provides the system to be fed through the generator. When the electric grid is restored, it disables the generator switch and activates the electric grid. Make sure the automatic transfer switch can match the amperage of your utility power. 200-Amper ATS is a good option for standard homes.

Air Cooled or Liquid Cooled?

Generators get very hot when running. And they need a cooler to reduce this heat. Generators use two types of cooling systems. One of them is air-cooling, and the other one is liquid-cooling. The air-cooling system uses air in the atmosphere. The cold air is taken into the generator and distributes it to certain parts of the generator. Thus, the air current is created and allows the generator to decline the temperature. In the long uses, air-cooled systems are insufficient in cooling.

On the other hand, in the liquid-cooled, the generator uses a cooling liquid to reduce the temperature. There are a radiator and a water pump. The fluid goes to the engine part of the generator, and the heat is transferred to the liquid, then the coolant goes to the radiator to cool. The generators more powerful than 20kw usually use a liquid-cooled system, which cools the generator better during prolonged use. However, liquid-cooled systems are more expensive than the air-cooled ones.

Fossil fuels are the largest source of electricity, but wind, water, and the sun can also generate electricity. Even electricity can be generated from plant waste, garbage, and animal droppings.


Placement of a generator considerably affects not only the performance of the generator but your health and safety. There are some elements you should take into account before the placement.

The generator produces carbon monoxide, which is harmful to health. Therefore, take care to place the generator at least one and a half meters away from the whole door, window, or ventilation to avoid this gas.

Never place the generator under a ledge, where there may be puddles or where snow can collect.

Ensure that there is sufficient space around the generator that service officials will not have trouble with maintenance or repair.

If you are sitting in a windy place, determine the direction of the wind blowing, do not let the harmful gas coming out of the generator be carried to your home by the wind and your neighbors’ house and disturbed

Whole house generators can be noisy. If there is a residential or apartment building close to where you are placing it, make sure the generator is far enough away from them that the sound does not disturb them. This situation also applies to your own home.

Try to place the generator close to the electricity meter and gas meter. In this way, by using shorter pipes, you both reduce your installation costs and reduce the voltage losses by reducing the path taken by the electricity. And this will increase your productivity.

Do not forget there can be specific rules in the local building code. If there are particular rules, you may unknowingly break these rules, and it can cause trouble when placing your generator.


In the 1880s, there was a “current war” between Nikola Tesla and Thomas Edison. Tesla invented AC, Edison invented DC, and both wanted their currents to be popular. AC won the war because it is safer and can be used over long distances.
