A generator provides power for a number of different applications, from powering a refrigerator to powering an entire house.
This guide is not intended to replace the need for a knowledgeable mechanic or electrical contractor to make any of these recommendations.
Generators are very complicated and feature-rich devices, so you’ll want some guidance from someone who knows what they’re talking about in order to get the best unit for your needs.
If you’re not sure what type of generator you need, get help from someone who knows or read this guide very carefully.
This guide will not address the technical aspects of how generators work, but some background information is useful to understand the economic issues that affect modern generators.
Generators make use of a number of different technologies, and each have their own positives and negatives aspects. Unfortunately, it’s very hard to predict how any particular technology will perform in a specific application.
So it’s best to focus on the economics instead of the technical details when choosing a generator.
Note: The information in this guide provides is based on my own experience with several different generators, Website reviews, Costomer Experiences and I am confident that the information presented in this guide is accurate & definitely helps you to choose the best generator.
6 Things to know before Buying a Generator
According to our research, 98% of People ask the same question again & again that is “what to look out for when buying a generator?“
So here are some general things to keep in mind when choosing a Generator:
Power Output: This is one of the biggest factors when choosing a generator. The power rating listed on the generator is usually based on a specific set of conditions normally, a specific voltage and frequency.
The lower the voltage and frequency, the higher the power output.
You should also be aware that if you’re using an inverter to convert power to AC (standard household current), the inverter will reduce the power output even more.
Size: This will depend almost entirely on how much power you need.
The bigger units will be more expensive & gives more Power, so you will have to calculate how much power you need versus how much you can afford to spend.
The larger the generator, the more fuel it will use, which means it’s likely to cost more over its lifetime. On the other hand, smaller generators are more portable, but they’re less powerful and less fuel-efficient.
Noise level: Generators generally generate a lot of noise, which is usually one of the first things to influence your decision. Generators are made in order to be quiet – some are quieter than others, but there’s no way to completely eliminate the noise factor.
Rotational speed: Automatic, variable-speed generators are becoming more and more popular, but they can get expensive.
The general rule of thumb is that the larger the generator, the faster it runs. Be aware that if you’re using an inverter to convert the power into AC current, the generator will run at its slowest speed.
Automatic or Manual: There are two main types of generators – automatic and manual.
Automatic generators work on a timer based on how much power you need and how often you use it where is Manual generators require a hand crank to operate them.
Energy source: Most of the generators in the market use an internal combustion engine, but some also use solar panels and/or wind turbines.
Fuel source: There are several ways that fuel can be burned in a generator.
The most common is to burn gasoline or diesel fuel in an internal combustion engine, which has many downsides , namely that it’s expensive, noisy, and generates a lot of pollutants as a result of its operation.
For these reasons, many modern generators either burn natural gas or gasoline.
The other alternative is to use a renewable energy source such as solar panels or wind turbines, which are also much cleaner than burning gasoline for your electricity needs.
Types of Generator
- Natural Gas
Here’s a list of some of the more popular generator types and a brief description of their advantages and disadvantages:
Portable generators: These are very similar to power tools, but can be used to generate electricity.
They’re usually quite compact and are very lightweight. They’re able to provide a lot more power than portable tools since they use better technology and a larger generator.
Most of these also produce less noise than stationary generators, which means that they’re usually the preferred generator type for homes.
Inverter/Fuel cells: These can be a good option if you’re looking for an alternative to burning one or more of the above fuels inside your generator.
Unfortunately, they’re quite expensive and very limited in their applications.
Alternative Energy: Some generators use alternatives to gas or diesel fuel. If you want to reduce your dependence on fossil fuels, generators that burn natural gas can be a good option.
Gasoline is also an option if you’re looking for something cheaper, but be aware that it still generates pollutants. A third option is hydrogen fuel cells, which are becoming more common.
These don’t burn anything at all and generate zero pollutants.
Gasoline engines: These use gasoline to power an internal combustion engine. They can run on anything from diesel fuel for when you’re doing woodwork to 100 octane gas for when you’re using your generator during a disaster. The biggest negative is that gasoline generators require regular maintenance and can be quite noisy.
Diesel engines: These run on a fuel called diesel. The most popular fuels are known as B-grade and A-grade diesel, which are both very similar in price and offer the best balance of fuel efficiency and reliability.
The biggest advantage of these is that they have few operating costs, which makes them extremely cost-effective over their lifetime. These generators require little maintenance and offer very low noise levels, but their main disadvantage is that they don’t run on natural gas or gasoline – they only run on diesel fuel.
Gasoline/gasoline hybrid: These are a bit of a special case, as they can use 2 different fuels – gasoline (petrol) or ethanol.
Most of these use gasoline to power an internal combustion engine and ethanol to generate the electricity you need.
I’ve included them here because they’re common enough that you might come across them during your search for a generator.
They have the same upsides and downsides as other gasoline engines, but some of them also have automatic shutdown mechanisms that prevent gas from spilling out if the generator is tipped over or otherwise damaged.
Powershift: These are about the same size as a portable generator and use an internal combustion engine and an electric motor to generate electricity. They’re fairly quiet, but they have some downsides.
The biggest drawback is that the electric motor doesn’t have a very high power output, so it can be difficult to run household appliances in your house.
This means that you’ll need more of them for a given amount of power than with a diesel engine or gas engine; however, this also means that you can use less of them since they consume less fuel.
The other major downside is that these generators require regular maintenance and will be more expensive to run over their lifetime than other types of generators.
Wind turbines: These can be pretty, but they can also be expensive. They generate low amounts of power, but they’re extremely high in price.
Because you can build your own windmill, you’ll save a lot on the initial cost of the turbine and the upkeep.
The biggest downside is that building your own windmill will take a long time and take up some space, so you’ll have to decide whether it’s worth it before making your decision to buy a generator.
Self-contained battery backup: This is one type of generator that doesn’t run off of fuel at all,
Instead it runs off of a battery that’s connected to a controller that controls everything from its operation to its location.
These are also known as battery backup generators. It’s a bit of a special case because it’s not actually what you’d call a generator, but it still fits into the category in that you can install them inside your home.
Hybrid: A lot of generators today are hybrids – they combine several types of energy to generate electricity, which means that you’re able to make use of whatever energy sources that are available at any given time.
For example, solar panels and wind turbines can both be combined with an internal combustion engine to create your own hybrid system.
This is one of the best ways to generate power since it works off of renewable, clean energy while also being able to draw on more traditional sources when those aren’t available
Water/air powered generators: These can be some of the most environmentally friendly generators around, as you don’t need any fossil fuels or an internal combustion engine while you’re using them.
They work by pumping water through 2 separate chambers – one that heats up while the other cools down – which is then sent through a radiator. The water is then used to power the internal combustion engine or a giant fan that provides a breeze to cool things off.
They have no moving parts, making them extremely reliable and quiet, but they consume quite a bit of water, which is why they’re more suited for large-scale use. There’s also very little maintenance needed too – you just need to periodically pump the radiator and keep an eye on the fan to make sure it’s running well.
Wind/hydroelectric generators: These are very similar to gas/diesel engines in that they directly run off of fuel; however, they generate electricity by harnessing energy from wind or hydroelectric plants. These don’t require any large amount of fuel and more than pay for themselves over time, but they can be quite noisy.
Water/pellet generators: These are very similar to wind/hydroelectric generators in that they run off of hydroelectric or wind power; however, the electricity is produced by burning wood pellets or dew.

History of Generator
The history of the generator spans back to antiquity. The word “generator” itself, in fact, derives from the Latin verb “generare”, which means “to produce”.
Generators have traditionally been used as sources of power for electrical devices. Early generators such as waterwheels or windmills were powered by natural forces and so were referred to as mechanical systems.
Nowadays, most generators are powered by electric motors and called electric generators. Electricity generated by the generator can be either distributed on-site for immediate use or transferred elsewhere through power lines for use in a distant location. Generators provide an almost limitless source of energy that is reliable and cost-effective. Some generators can also be used for the transportation of goods.
There are two main types of generator: “linear generator” and “rotary generator”.
Linear generator: A linear generator is an assembly of mechanical components that are organized to convert the energy from a natural source (e.g. moving water or wind) into electric energy.
The linear generator “converts the linear motion of a fluid (water) or wind into rotary motion”, which ultimately turns the rotor and produces electric power. Linear generators include hydroelectric dams, wind turbines, moving water-wheels, paddle wheels, and vehicle power generators.
Rotary generator: A rotary generator or “rotor generator” uses a rotating mechanism to generate electric power. As a result of the rotation, the magnetic field of the stator creates an induced current in the rotor. The rotational motion of the rotor can be either mechanical or electrical.
Rotary generators include electric turbines and wind turbines. Historically, these two main types have dominated as a generator for commercial applications. In recent times, however, there has been more extensive use of linear generators for large-scale electricity generation due to their higher reliability and productivity compared to rotary generators.
This is because linear generators can be made of solid-state components that do not need any lubrication (which is required by mechanical components of rotary generators). Besides, linear generators have a comparatively lower cost of maintenance and greater efficiency when compared to rotary generators.
Some types of electric machines can be adapted to operate as either linear or rotary generators. This is achieved by mechanically connecting the machine’s stator with its rotor at some convenient point.
Connecting the stator with the rotor causes the entire assembly to act as a single generator in whichever mode it is operated in. This type of connection is termed “direct-drive” connection (because there are no power transmission belts or gears involved).
The direct-drive approach allows for high reliability since there are no mechanical couplings involved that could become defective or damaged over time due to wear and tear. The direct-drive approach is generally used only in large-scale power generators.
A generator can be categorized into a number of different types based on its design, intended functions, and applications.
An electrical generator converts mechanical energy, flowing in as kinetic energy (e.g. from a rotating turbine), into electrical energy, flowing out as electric current. The conversion involves two circuits: the “source circuit” and the “load circuit”.
Besides the source and load circuits, there are three other circuits that take part in the operation of an electrical generator during its discharge cycle: the excitation circuit, the regulation circuit, and the impedance (or armature) circuit. These three additional circuits have the same basic concept as the source and load circuits, but they have very different functions.
The excitation circuit is a battery-like circuit that contains an electromagnet that supplies energy to the generator during its “charging” phase. When an electrical generator is operating, its working voltage is much higher than its grid-voltage (e.g. 0.5 V vs 0 V).
This difference between working voltage and grid voltage requires a source of energy to charge the generator during its charging phase before it can start working. The purpose of the excitation circuit then becomes providing that source of energy to the generator, and in most applications, it is created by using another generator or alternator (see below).
This phase of the generator’s cycle is often referred to as “charging” because it involves charging the generator in order for it to produce energy. The amount of charging time required varies, however, depending on the type of generator (i.e. linear or rotary).
The regulation circuit regulates the voltage produced by the generator to match its grid-voltage and can be found in both linear and rotary generators.
The regulation circuit generally involves some form of shunt regulator that is controlled by a feedback loop which measures the output voltage (i.e. output current) and adjusts its controlling potentiometer accordingly thus keeping the output voltage constant during operation.
The regulating potentiometer is generally located in the load output connector so that it can be adjusted from outside the generator. As with most other components of a generator, regulation is achieved by the use of electrical resistors.
The impedance (or armature) circuit contains both coils (see below) and electrical resistors that are used to maintain constant power transfer as the output power remains relatively stable during operation. During “charging” this circuit also acts as a resistance which generates heat.
In some applications, such as wind turbines, electromagnets are used in place of batteries because they generate less mechanical torque and produce less heat when compared to batteries. In this application, the generator is connected to the electromagnets through a series of resistors which is called a “vane” generator. As with other types of generators, the vane generator also produces its own heat during operation.
In another type of application (e.g. photovoltaic power plants), a linear current generator called an “accelerator” connects directly to the mechanical “flywheel” that is used to store mechanical energy in order to produce electrical energy later in the cycle. The accelerator circuit can be found in both linear and rotary generators and produces no heat during operation.
When a rotating mechanical component is used as a generator, its rotation also produces energy. In this application, the generator consists of two main sections: the stator which converts mechanical energy into electrical energy and the rotor which converts electrical energy into mechanical energy. In this type of generator, the stator and rotor are generally connected mechanically to one another at some convenient point.
In this type of generator, electricity is produced by using an electromagnetic field to produce radial forces that are transferred to a conducting fluid. These radial forces produce a pressure in the conducting fluid and move it inwards towards an inner core or “turbine”. This inwards-moving fluid is then used to drive a turbine or alternator that produces electrical energy.
The general concept behind a generator using this approach is the same as any other generator, however the end-result is very different from “conventional” generators. Instead of being used to create electricity, electromagnetic fields can also be used to convert mechanical energy into electrical energy.
This type of generator does not use any chemical reactions such as those that occur in batteries to generate electricity, and therefore it is referred to as an “alternator”. The alternator can be found in many different types of equipment (e.g. automobiles, aircraft) where its main use is providing direct current (DC) electricity for battery charging (e.g. 12 V, 24 V). The alternator is often used in conjunction with a battery to provide electricity in applications where a constant flow of energy is required (i.e. vehicles) and for cases where the alternator itself cannot charge the battery (i.e. when the engine is running).
One example of an alternator-type generator is the dynamo, which converts mechanical energy into electrical energy by moving conductive plates that are held within an electromagnetic field (see magnetic core and Faraday’s law). Smaller generators often use permanent magnets in place of electromagnets because they are much cheaper to operate and produce less heat when compared to electromagnets.
A different type of alternator that is used in applications where a constant steady supply of energy is required (e.g. in photovoltaic power plants) is the “synchronous machine”. It converts mechanical energy into electrical energy using a set of conductive rotating elements called “rotor” and a set of stationary conductors called “stator”. The synchronous machine uses a rotating magnetic field to induce current flow in its rotors, and this characteristic is known as self-regulation because the machine’s output voltage automatically adjusts itself to balance out any fluctuations or loads that may be placed on it. As with earlier versions, the rotor can be constructed from permanent magnets or electromagnets.
In the electric motor, electricity generated by a generator is transferred to a rotating electrical rotor consisting of a set of electromagnets which is mechanically linked with the stator. The result is that the rotor produces electrical energy through electromagnetic induction.
Synchronous motors use only one type of magnetic field (i.e. continuous instead of discontinous). The flux linkage and therefore the torque produced by an alternator-type motor are different from those produced by a synchronous motor; however, these differences are minor when compared to other differences they have in common.
Synchronous motors produce a constant voltage through the use of a set of resisting magnets that are permanently attracted to the stationary conductor-like rotor. The attractive forces between the magnets and rotor cause the magnetic flux produced by the motor to be constantly transferred to its stator, and therefore produce a constant voltage through resistance alone.
Although it can be used in systems with continuous-, half- or full-wave rectification, synchronous motors are most commonly used with three-phase voltage or current which consists of three equal positive half cycles (each one being 180 degrees out of phase from each other) and two equal negative half cycles (each one being 360 degrees out of phase from each other). This type of three-phase voltage is known as a sine wave and the variation of it with the position of the frequency dial is known as a sine waveform.
Three-phase electric motors are used in systems that have two or more voltages or currents in order to provide a continuous source of power for many applications. Power produced by synchronous motors can be supplied or controlled independently from other sources (i.e. wind, solar, fossil fuels, etc.). In addition, three-phase electric motors can have both high efficiency and high speed compared to one-, two-, and three phases with similar wattage outputs.
An AC generator is a device that converts mechanical energy into electrical energy by using magnets and coils to produce a magnetic field.
AC generators are typically used in applications where power is needed but its frequency and voltage cannot be controlled, such as controlling the flow of water or the operation of motors. AC generators are also used in applications where it is necessary to convert from one voltage (e.g. 110 V) to another (e.g. 220 V). This type of equipment can also be called an “AC/DC generator”, which refers to it being capable of producing both direct current and alternating current electricity.
The common types of AC generator include the induction generator, synchronous generator, and rotary converter.
In the synchronous generator, electricity is produced by using a rotating magnetic field to induce current flow through a conductive set of coils. The coils are held within the magnet’s poles and the amount of electrical energy they produce is directly related to how fast they move within the magnetic field.
The induction generator uses electromagnets to produce electric currents that are created by changing magnetic fields within two electromagnetic conductors (i.e. a “rotor” and a “stator”). It does not require any form of mechanical prime mover to make it rotate and it is dependent upon an external power source (i.e. external electric power) to operate.
The rotary converter uses a set of electromagnets to produce alternating current and DC electrical energy by using conductive coils which are magnetically attracted to the permanent magnets in the rotor. The rotor is held within an electromagnetic field and it turns on its own axis in order to produce electricity that can be used directly or converted into other types of power.
A generator’s efficiency can be measured by calculating the power that is produced for every unit of input energy through the formula P = P out ⁄P in , where P out is the output power and P in is the input power. The efficiency is also calculated by the formula formula_4, where formula_5 is the power in watts, P in is the input power in watts and formula_6 is the output power in watts. The efficiency of an AC generator can be found by calculating its efficiency using the load feature of a load flow diagram.
A motor’s output can be directly measured or controlled through various methods and it has two forms (i.e. direct current and alternating current). In direct current motors, electricity is produced by using electromagnets to generate a rotating magnetic field that induces current flow through a conductive set of coils which are physically connected to a non-rotating rotor that requires mechanical force to move itself.
In alternating current motors, a moving conductor (usually contained in a conductive set of coils) is somehow convinced to move by the rotation of an electrically-induced magnetic field.
The formula that determines the power output of a motor in watts is P = P out ⁄P in , where P out is the output power and P in is the input power. The efficiency of a motor can be found by calculating its efficiency using the load feature of a load flow diagram.
Since AC generators and AC motors are powered by electricity, they both can be used as electrical generators (i.e. convert mechanical energy into electrical energy) or as electrical motors (i.e. convert electrical energy into mechanical energy).
A sensor is a device that relies on magnetic fields, electric fields and heat to detect events that occur within them.
Magnetic sensors are commonly used in applications where it is necessary to detect moving objects, such as the measurement of the rotation speed of a rotating shaft or the movement of an arm that makes contact with something. Sensor modules are also used in applications where it is necessary to detect changes in electric current, temperature or voltage levels within a system of electrical components (i.e. electronic components).
A temperature sensor is a device that relies on thermal energy to detect events that occur within it. It is commonly used in applications where it is necessary to determine the amount of energy that is being used or stored within a system of electrical components (i.e. electronic components).
Temperature sensors are also commonly used in applications where it is necessary to detect the angular displacement of an object (i.e. the rotation speed of a rotating shaft) or the movement of an arm that makes contact with something (i.e. magnetic field).
Temperature sensors are also commonly used in applications where it is necessary to detect changes in electric current, voltage levels and power consumption within a system of electrical components (i.e. electronic components).
A voltage sensor monitors changes in electric current, voltage levels and power consumption within a system of electrical components (i.e. electronic components). It is also commonly used in applications where it is necessary to detect the angular displacement of an object (i.e. the rotation speed of a rotating shaft) or the movement of an arm that makes contact with something (i.e. magnetic field).
Voltage sensors are also commonly used in applications where it is necessary to detect changes in electric current, temperature, or light levels within a system of electrical components (i.e. electronic components).
Current sensors are used to determine the amount of electrical current (i.e. electrons) that is being passed through an electrical circuit in the form of a straight line. This is done by using an electrical resistor to generate a voltage that is proportional to the amount of current passing through it.
Current sensors can also be used to determine the angular displacement of an object (i.e. the rotation speed of a rotating shaft) or the movement of an arm that makes contact with something (i.e. magnetic field).
Current sensors are also commonly used in applications where it is necessary to detect the amount of power being consumed by an electrical circuit in watts or the angular displacement of an object (i.e. the rotation speed of a rotating shaft) or the movement of an arm that makes contact with something (i.e. magnetic field).
A voltage sensor is a device that measures electrical changes that occur within it in order to determine the amount of current passing through it or a change in current flow which creates a voltage which is proportional to the amount of current passing through it. Voltage sensors are commonly used in applications where it is necessary to detect changes in electric current, voltage levels or power consumption within a system of electrical components (i.e. electronic components).
A current sensor measures electrical changes that occur within it in order to determine the amount of current passing through it. Current sensors are commonly used in applications where it is necessary to detect changes in electric current, voltage levels or power consumption within a system of electrical components (i.e. electronic components).
A potentiometer is used to control the amount of current flowing through an electrical circuit by changing the resistance of a set of resistors as a result of passing an amount of electric current through them. It is also commonly used in applications where it is necessary to control the amount of voltage being applied across a load with a variable resistance.
A circuit breaker is a device which protects an electrical circuit from excessive discharge of current, usually caused by short-circuiting.
An ammeter is used to measure electric current in amperes. This involves the use of a purely resistive load for measuring electric current (i.e. electrons) flowing through an electrical circuit in the form of a straight line. It is commonly used in applications where it is necessary to control the amount of current being applied across a load as a result of passing it through an electrical resistor or when it is necessary to determine the amount of energy being consumed or stored within an system of electrical components (i.e. electronic components).
A semiconductor comprises a number of doped band-like structures, usually silicon, which are embedded in a host semiconducting material. The band structures are fabricated to include multiple regions or layers which can be used as electronic devices. Semiconductors typically have p-n junctions and n-wells (i.e. p-type doping regions) that provide charge carriers, such as electrons and holes. A pn junction is formed when an electron with a negative charge enters the p-type region or when an electron with a positive charge leaves the n-type region. The difference in the number of electrons can result in an electrical current flow.
A transistor is an electronic switching device that can be used to amplify or switch an electric current. It is most commonly found as a semiconductor component but can also be fabricated from other materials. Transistors typically have n-wells (i.e. p-type doping regions) that are used as electrodes, n-doped regions (p-n junctions) between the well and the source/drain region, a metal gate for controlling the passage of current through the device and a channel leading to the control gate and base regions which results in exciting photons.
A transistor can be used to amplify an electric current by turning it on or off. It can also be used as a switch by controlling the voltage applied to its input terminals. The amount of current flowing through a transistor is proportional to the voltage being applied as well as the number of electrons that are transferred through its source/drain region when a current is applied to it (i.e. when it is turned on). FIG. 1 shows a p-n junction being energized and the resulting movement of electrons and holes in order for an electric current to pass through it, which leads to the creation of photons and results in light being emitted from an LED device that may be connected in series with this junction, i.e. in parallel with this junction.
The current through a light emitting device is proportional to the voltage applied across it, which can be measured by a resistor that is placed in series with the LED. This resistance value represents the amount of electrical current flowing through the LED at any given time (i.e. when it is turned on). The current flow through an LED can be measured using a current sensor where it is connected in series with the LED and used to detect electrical currents as they pass through this device. The resistance value measured between an LED and a resistor can be used to determine the amount of current being applied across the resistor through this device.
The voltage applied across an LED can be controlled by controlling the amount of current flowing through it, which is measured using a voltage sensor that is connected in series with this device. The resistance value measured between an LED and a voltage sensor can be used to determine the amount of current flowing through an LED from its power supply.
A light emitting diode (LED) is a semiconductor device that emits light when electric current flows through it, which may be arranged in series with this device (i.e. in parallel with this device). The light emitted from an LED through its active region (i.e. junction) originates due to the generation of photons, which is a result of applying an electrical current to it (i.e. when it is turned on). An LED will emit a certain wavelength of light depending on the energy bandgap of the semiconducting material which is used to fabricate its active region or p-n junction.
