Types Of The Generator

Stationary GeneratorsPortable Generators

Stationary Generators

A stationary generator is also called a standby generator. It is a back-up electrical system that supplies power to the electrical circuits within seconds of a power outage. The auto sensor takes care of sensing the power outage transferring the electrical load to the generator and vice versa. Most of these generators use diesel, natural gas or liquid propane gas.

Portable Generators

As the name suggests, portable generators are generators that can be easily carried from one place to another. They are gas or diesel powered devices that use a combustion engine to provide power to the electrical circuits in case of a power outage.

Features To Consider In A Good Portable Generator

  • Automatic Start

As the name suggests, an automatic start generator senses a power cut and starts supplying power to the electric circuit automatically when there is an electric outage. There is no need for human intervention and it is a blessing in disguise for ensuring consistent power supply remotely. However, this option will only work if regular maintenance activity is carried out to ensure smooth working of the generator.

  • Electric Start

Electric start generators run on batteries and it is very important to keep the batteries charged to ensure that the generator is able to start and supply electricity to the electric circuit when there is a power outage. Electric start is much easier and convenient as compared to pulling the cord to start the generator.

  • Alternative Fuel Capacity

Choosing a generator with an alternative fuel capacity can prove useful if there is unavailability of one type of fuel. It is necessary to choose a generator that uses easily available types of fuel. The renewable energy generators are very popular nowadays.

  • Wheels

One great feature is having a generator on wheels. This makes it convenient to move the generator around with ease. This is very important if there are ladies who would be operating the generator in absence of their male counterparts in the house.

  • Fuel Gauge

Fuel gauge is important as it indicates the quantity of fuel that is available for use in the generator. This ensures that fuel is topped up as soon as or before it reaches the minimum level.

  • Low-Oil Shutoff

The low-oil shutoff feature is a very important feature that shuts down the generator when the level of oil reaches a minimum level. This prevents the generator from getting damaged due to less oil.

  • Inverter Technology

The inverter technology is a relatively recent development used in generators. This has been made possible with the use of electromagnetic technology that combines advanced electronic circuits and high tech magnets. These generators are referred to as Inverter Generators and they provide the qualities of an inverter in addition to those of a generator.

  • Multiple Outlets

It is a wise decision to choose a portable generator with multiple outlets in order to be able to attach multiple devices and keep them running smoothly in case of power outage.

  • Removable Console

A removable console is helpful as appliances can be directly plugged into the portable generator by eliminating the use of the extension cords that can be potentially dangerous.
