Types of Generators

Generators are used for the generation of electricity and they ensure that most of the essential appliances can be run whenever there is a power outage. Generators of different wattage capacities can be used according to the needs of the individual. The choice of buying the right type of generator depends upon a number of factors like the wattage capacity, voltage ratings, fuel type, fuel efficiency, noise level, portability and price. A prudent choice can only be made if you know what to look for.

Stand By

Standby generators provide backup power in homes and offices and are permanently installed outside the house or office building. They are plugged into the electric circuits or home wiring.  The unit turns itself on and off automatically. They can automatically detect disruption in the usual electric supply and begin supplying power within a few seconds.  Propane and natural gas offer a safe, long-term fuel supply and are more environment friendly than gasoline or diesel fuels.  Like any motor, a generator motor creates quite a bit of heat and needs a cooling system to prevent overheating. Standby generators can be either air-cooled or liquid-cooled. The major difference is that air-cooled systems are louder and not quite as effective. Liquid cooled systems are quieter and more dependable  and also more expensive to purchase and to maintain.


Portable generators are usually used in places where there is no power supply such as construction sites, camps, etc. These generators are sufficient to run appliances like televisions, refrigerators, sump pumps and furnaces.  Portable systems are wheeled units that require to roll the generator outside, start it up, and hook it up to a power inlet box Portable generators supply electricity to selected appliances through extension cords.  They are fueled by gasoline, which can be difficult to store and transport during a blackout. Carbon monoxide is always a concern in the safe use of portable generators.  They are designed to be used for short periods of time, only a few hours at a stretch. As a result, they tend to be much smaller and less expensive.

A related aspect of generator motors is the speed at which they run, as measured in RPMs. Generators made for the US market operate at one of two speeds: 1800 RPM or 3600 RPM. 1800 RPM motors will last longer and run quieter; 3600 RPM motors are smaller and lighter.
