Standby Generators; these are emergency stationary generators designed to kick in and run all or most of your business and home appliances or electrical systems when there is a power outage. They often have an automated starting system which trips on when there is a power cut. A transfer switch will disconnect the power load from the mains in the case of a power failure and then connect it to the generator unit.
PTO Generators; these generators work off a tractor and are handy units for around the farm or yard. They are available in three phase or single phase and produce up to 155 kW of power.
Two Bearing Generators; are often seen on service trucks. They use a pulley system in a variety of power sources.
Industrial and Portable Construction Generators; widely used on various job sites and industrial situations. They are usually very portable and easy to move around construction sites. These generators come in three phase or single phase and are powered by diesel or gasoline. 180 Hz of power is available for the high-cycle vibrators and 60 Hz of power for your standard electric tools.
Vehicle-Mounted Generators; they stand mounted on vehicles for many purposes including emergencies, and for the application in mining, spray foam, construction, etc.
Portable RV/Recreational Generators; these generators are super quiet with their inverter technology, making them ideal for recreational use and areas where it is desirable to reduce noise. Powered by petrol, they are also ideal for computers with their sensitive electronics.
Welder Generators: these units run on either diesel or petrol and are a combination of a generator with welding capabilities available within the unit.
Portable Residential Generators; probably the best backup model for a power outage when it occurs in the home. These units are a good standby for running essential appliances and electrical items in and around the home such as fridge/freezers, lights, pumps, and electrical tools, etc. These generators usually run on petrol, but some of the models run on natural gas, LPG, or a combination of all three.
Mobile Towable Generators; as the name suggests, these generators provide power that is portable for construction and industrial applications. They run on diesel and come in switchable voltage models, making them ideal for many voltage applications.
Options when buying a portable generator
Things to consider when buying a generator:
Use: what will be its use? (see above descriptions).
Cost; You will find generator costs listed by wattage, and the general rule of thumb is…the higher the wattage, the higher the cost. Also, the higher the wattage, the less noise and the smoother the power. The cost will also be determined by whether it has an electric start or inverter technology.
The following are a few examples of what you can expect to pay for various new generators:
