How To Choose The Right Generator – A Complete Guideline 2020

by Brian Beltran

In some places, power loss occurrence happens once a year or twice for about 3 hours. This problem can be easily deal with a power inverter smoothly. But for natural disasters or extreme weather can cause power outages for weeks.  The inverter can’t support this long as it needs the power to charge itself after a certain time. The best 10000-watt generator will take care of your power problem without an issue. But the issue users face is how to choose the right generator. Check out the information’s given below and make the best decision as soon as possible.

How to Determine Which Generator Do I Need?

It is not a good experience to stay in the dark for a long time, especially your home appliances. You have to deal with spoiled food, frozen pipes, flooded basements, and many more disasters. You don’t have to experience this if you take the best dual fuel portable generator for use, but you need to determine which generator is efficient for you.

How To Choose The Right Generator - A Complete Guideline 2020

At first, you have to figure the wattage power you need and, secondly, a powerful generator that can exceed the needs of electricity.

Actually, the generator size is calculated on the basis of electrical output, not on physical measurement. The measurement is done in watts or Kw (1kW = 1000W).

Why is the size important? Because if you go for a too-small generator, the generator will not be able to handle the power overload. And the result will be the generator will stop working, and your appliances will get damaged soon. And if you go for the BIG generator, then it will be expensive to operate. So calculating the size is important.

While calculating, first make a list of the appliances you want to run with the generator. Then fix the start and run wattage of the listed device. You will find the wattage numbers in the appliances label. After that, add all the wattage numbers. The sum of the wattage numbers is the perfect size of your generator.

Types of Generators

In the market, you will find a variety of generators for home and commercial use. Here I listed the popular ones that the users have recommended. Go through the list properly then pick the one that will meet your needs.

Types of Generators

Diesel generators:

Diesel generator uses diesel fuel and electrical power. This generator is best for durability, long-lasting life, and requires less maintenance. For diesel fuel, the generator produces less heat and prevents overload on the engine. You will get high energy and efficient power with this generator at a low cost.

Environmental gas generators:

The most widely used generator is the natural gas generator. This generator uses dissolved petroleum or propane to produce energy. As natural gas is storable and provides endless supply, you will not have to think about running out of fuel. This clean and cheap generator is recommendable for environment-friendly features.

Gasoline generators:

The most common generator is the gasoline generator for the availability of gasoline. This generator is highly portable for size and runs at a low cost. So, you can use this generator per your requirements anywhere you need. You will see this type of generator is mostly used in a construction site, campsite, and for home use. But the back draw of this generator is noise and needs regular maintenance.

Standby generators:

This generator is an automatic generator, and it runs on gas or diesel for 48 hours without any need for a refuel. A standby generator has a strong engine with a skid that comes with a fuel tank, radiator, and a big alternator. There is an automatic transmission switch that allows power flow whenever the electricity goes out. The detection of power loss o this generator is super. It will start in seconds after sensing the power is out. This big and strong generator is used in medical support, elevators, and fire protection systems.

Portable generators:

For producing brief electrical power with gas or diesel, portable generators are the best choice. You can use it in any isolated site and also in the home to run refrigerators and televisions. This generator allows you to use it in two ways, one is by using the wired in the sub-panel, and the other way is plugging the devices in the generator’s power sockets. It is best to use in the places where the power cut happens for a short time.

Solar generators:

This generator is interesting to use as it uses the sunlight as power. Solar power is a simple but powerful energy that can be stored by solar generators easily. After capturing the sun’s light power, the power charges the battery then the battery produces electricity. But the battery needs to recharge for eight hours in direct sunlight.

Inverter generator:

Unlike any other generator, the inverter generator is the quietest one.  There is an alternator that converts the AC power to DC power to run the electronic gadgets safely. You will get long, smooth, and highly efficient power energy from this generator.

How To Choose The Right Generator?

The right generator is the best investment to stay prepared in any emergency power outage. As the power grid getting less reliable and power outage is frequently happening, you have to go for the generator to deal with this problem. As picking the right one is challenging, here you will get a helpful guide to choose the right one for your use.


Determine the wattage:

The size of the generator depends on the power supply need for your equipment. You have to calculate the wattage power of the devices you will use with the generator. The total wattage power determines the size of the generator.  It is better to pick the best 10000-watt generator for home if you want to run most of the household devices with the generator.

The number of outputs:

For multi-use, you have to look for the generator that has several output plugs. If you want to run the whole house with the generator, then install a power transfer switch to get smooth power in the systems.

Generator with rectifier:

The modern generators come with a rectifier that converts power in a smooth sine wave. This output waveform is best to run electric gadgets and LCD TV.


It is obvious that the size of the generator is related to weight. You will get generators between 29lbs to 215lbs.  But you have to keep in mind that a lightweight generator with high wattage will cost money. I will recommend going for the light one as the heavier one is not portable.

Run time and fuel:

Many generators run on propane or gasoline. You have to pick the generator with fuel efficiency and effective runtime. You cannot take the generator that runs for only two hours or less. Pick the one that needs less fuel and provides power for a long time.

Why Should You Buy a Generator?

Generators make your life in the dark easy, especially when the mother nature is rough outside. Till not sure to go for the generator, then let me help you to understand:

  • The generators are able to deliver power fast and automatically during the blackout.
  • You are free to operate any kind of heating and cooling systems, computers, and TV smoothly.
  • In an emergency situation, you can stay safe with comfort in your home.
  • No chance of having harmful voltage instabilities after the power gets on.

Frequently Asked Questions

What Will Happen If I Overload My Generator?

If your generator is not protected against an overload system, then your generator will get overheated, and it will shut down automatically.

Which is a more efficient gas or diesel generator?

The diesel generator is more efficient because it uses less fuel.

Can you run a generator continuously?

No, you cannot run the generator continuously because it is not designed to run for so long.

Can a generator stand in the rain?

No, the instructions warn not to run a generator in the rain.

What are the causes of the overloading of generators?

Overloading of generators is caused by the extreme voltage run from multiple devices.

Watch Out How to Choose a Generator

Final Remarks

The generator works as a great backup power source during the power outage, construction job, and any portable power you need. Just know the process of how to choose the right generator for your requirement and enjoy the smooth power source. And remember to follow the manual instructions to operate the generator safely and soundly
