Generators Buyer's Guide
Written by Dan GibsonIntroduction
Generator is a device that converts mechanical energy into electrical energy. It is commonly used as an emergency power source for homes, businesses and recreational activities. Generators come in many different shapes, sizes and capacities. Choosing the right generator for your needs requires some knowledge about the different types of generators and their features and benefits. This guide will provide an overview of the different types of generators and their features in order to help you make an informed decision when purchasing a generator.
Types of Generators
There are various types of generators available in the market today. Depending on your needs and budget, you can choose from portable generators, standby generators, inverter generators and commercial generators. Portable generators are the most common type of generator and are often used in camping and recreational activities. Standby generators are permanently mounted on a concrete slab and used for back-up power for homes or businesses. They are intended for extended use and are more expensive than portable generators. Inverter generators are lightweight and quiet, making them ideal for camping and recreational activities. Commercial generators are the largest and most powerful of the group and are often used for industrial purposes.
Portable Generators
Portable generators are the most popular type of generator and are used for a wide variety of applications. They are designed to be easily transported and are often used for camping, tailgating and recreational activities. Portable generators are available in a variety of sizes and power capacities, and are the most affordable option. They are usually powered by gasoline or diesel and are relatively noisy when in use.
Standby Generators
Standby generators are permanently mounted on a concrete slab and used for back-up power for homes or businesses. They are designed to be used for extended periods and are more expensive than portable generators. Standby generators are usually powered by natural gas or propane and are relatively quiet when running. Standby generators require professional installation and regular maintenance.
Inverter Generators
Inverter generators are lightweight and quiet, making them ideal for camping, recreational activities, and home use. They are powered by gasoline or diesel and are designed to provide clean, efficient power. Inverter generators are more expensive than portable generators, but are often quieter and more fuel-efficient.
Commercial Generators
Commercial generators are the largest and most powerful of the generator types and are often used for industrial purposes. They are usually powered by natural gas or diesel and require professional installation. Commercial generators are the most expensive option and are designed to provide a reliable source of power for extended periods of time.
