Types of Whole House Generators
There are two basic types of generators. Manual and automatic switches both are available in different sizes. The smaller ones are portable, and they come with caster wheels. The main goal is to be used wherever they are needed.
Automatic Transfer Switch
The ATS will automatically turn on the unit when the power outage. The main advantage of ATS is that you do not have to be home to start the generator. If you live in such an area that faces frequent power failures, an automatic transfer switch generator is recommended. The ATS generators are available in different 3 different sizes 50, 100, and 200 amps.

The Essential Feature of The Best Whole House Generator
If you are looking at different generators on the market to power your home, you will defiantly find that there are some features that you need to explain. It’s not just that all generators have all these features. More explanation will help you to decide features are essential to you. Here is a list of features available in the best whole house generator.
If you think about the comfort of your family, you must buy a generator that starts automatically when the power goes out.
If you want to move your generator quickly from one place to another, you should purchase a generator that comes with the wheels.
Another powerful feature, if you purchase a generator that provides electricity with electric start. So, there’s no need to use the pull-start every single time when you need to switch on the unit.
The majority of generators come with the facility of more than dual fuel generator. For instance, some generators can work with both propane and gasoline.
The fuel gauge feature makes it simpler to determine when you need to add fuel in the tank of your generator.
Understanding Best Whole House Generator Fuel Choice
Diesel is the traditional fuel choice of many appliances and backup power machines. There are many benefits of diesel, such as high thermal efficiency, so that it will yield a low cost per KW in large appliances.
Also, Diesel stores on site, so it can be used in remote areas where natural gas is not a workable option.
For cost-effectiveness, perceptions of fuel durability, reliability, and power density, gaseous fuels were avoided in the past.
However, the new technological advancements changed that. There are hardened seats and values to optimized fuel mixtures.
Natural gas generators run similarly to gasoline-powered. An internal combustion engine introduces a blend of fuel and air into the combustion chamber, and the piston compresses the mixture.
Unlike gasoline and diesel-powered generators, natural gas generators must have the ability to burn gaseous fuel rather than liquid ones.
Liquid Propane (LP)
Liquefied or liquid petroleum gas (LPG or LP) is a mixture of hydrocarbon gases that are known as propane or butane and used in heating appliances, cooking equipment, and vehicles.
In the backup power system, this can be in LP liquid and LP vapor configurations. We recommend you to prefer LP vapor.
The spark ignited fuel run in automotive engines adapted for its use. LP must be stored on-site as diesel; therefore, it gives a tremendous gaseous-fuel. An alternative to diesel for appliances that need on-site but it has the features of no fuel spoilage.
