Most people ask - Can I ever get the right generator? This is a challenge for most users. Here, you’ll understand everything necessary. Also, you’ll overcome the fear of choosing the perfect type. Please continue reading to widen your knowledge in this regard. Enjoy!

What Is a Generator?

Before knowing how to choose the right generator, let us know more about them. When we are off the grid, we may need to generate power. A generator serves multiple functions. It is a device or machine that helps in converting mechanical to electrical energy. With the latter, power is generated for diverse uses.

Generators can convert their electrical energy. They can do this even without connecting to any power grid. It mostly depends on gas just like the way cars do. It can transform chemical energy into electrical energy. They achieve this by capturing the power of motion.

How Do I Choose the Right Generator?

Before choosing a Generator, understand how they work and know the different types. Also, there are some features to consider before making your choice. This helps you know the best to go for. 

How Do Generators Work?

A generator does not generate electricity. They only convert mechanical or chemical energy to electrical energy. This is known as electromagnetic induction, established by Michael Faraday. The first process of converting energy is that the engine creates motion. This energy then ensures the production of electric charges. Then, they are forced through a magnetic field’s conductor. The final result is a current that powers all appliances or gadgets.

Moving an electrical conductor could cause electric charge flow. This could be a wire possessing charges. The result is that this causes a difference in voltage between the conductor’s two ends. This triggers the passage of electric charges thereby generating current.

The generator has some specific features that enable the device to work. These could be regarded as their major components. Without them, it is incomplete and can never function. Let’s consider them.


This could be taken as the "backbone" or "powerhouse" of the generator. Its engine’s size differs in various models. It influences the highest power output that can be supplied by any generator.

Different generator engines function using various kinds of fuel. These include gasoline, diesel, natural gas, or propane. The smaller ones mostly run on gasoline. The larger ones usually operate on liquid propane, diesel, natural gas, or propane gas. However, some run on dual fuel.


This is also regarded as the "gearhead". This produces the electrical output from the mechanical input released by the engine. It features a gathering of stationary and moving parts built-in housing. These components connect to cause relative moments between the magnetic and electric fields. In the end, this generates electricity.

Voltage Regulator

The voltage regulator regulates the output voltage. It has some features that play a role in the cyclical process of voltage control. This component ensures the conversion of alternating current to direct current. It then feeds the DC to the exciter windings. This converts the direct current to alternating current. It works in line with the primary stator winding and produces a little AC. These windings are intertwined to units called the rotating rectifiers.

The Rotating Rectifiers

The rotating rectifiers help to refine the AC produced and rectify it to the DC. Afterward, the latter is fed to the rotor to generate an electromagnetic field. This adds to the rotating magnetic field of the rotor.


The rotor then produces a bigger AC voltage across the windings of the stator. The generator then induces more output AC voltage. This continues till the generator produces a voltage equal to its highest capacity. Once the generator’s output increases, the voltage regulator generates little DC.

The moment it runs at full capacity, the voltage regulator reaches a state of equilibrium. As such, it generates sufficient DC to sustain the generator's output.

Cooling and Exhaust System

Cooling System

When one runs the generator continuously without a break, its components begin to heat up. It is, therefore, crucial to have a cooling system to extract the heat produced.

Check the coolant levels of the generator each day. Flush the cooling system and raw water pump at least every 600 hours of operation. Also, wipe its heat exchanger at least after working continuously for 2,400 hours.

Keep your generator in an open and ventilated location. Users must allow at least 3 feet at every side of their generator. This is to give way for the free flow of cooling air.

Exhaust System

Generators emit fumes, which are injurious to our health. It is however important to install an appropriate exhaust system that can dispose of it.

Cast iron, steel, or wrought iron, are usually used in manufacturing exhaust pipes. They must be freestanding. This means they shouldn’t get assistance from the generator's engine.

These pipes are mostly joined to the generator’s engine. They make use of connectors to help reduce vibrations. It also stops any form of damage to the generator's exhaust system.

Control Panel

The control panel is the generator’s user interface. It features some provisions for controls and outlets. Let’s consider its components.

Electric auto-start & shutdown

The auto-start control panels are put on the generator automatically during a grid-off. This also controls it while running. It also shuts the unit down without manual intervention when it is no longer in use.

Engine gauge

Various gauges show essential parameters. These include battery voltage, oil pressure, operation duration, and more. Their regular measurements and supervision allow the shutdown of the generator. This will happen in case any of them cross their different threshold levels.

Generator gauges

Generators feature meters that measure the output voltage, current and frequency of operation. Other controls include phase selector, frequency, and engine control switches. The latter could be auto or manual mode.

What Are The Types of Generators?

There are different types of generators. Each of them fits in for different purposes.

Inverter Generator

This generator is mostly quieter and smaller in size compared to other types. It is also fuel-efficient. This type is very safe for powering sensitive electronics. It is quite expensive. If demands are low, it utilizes the fuel required to provide the necessary power.

This portable generator is less expensive than a standby one. One great advantage of this type is that it is easy to transport. However, it has placement restrictions because it produces carbon monoxide. Therefore, it should be placed not less than 20 feet away from the building. Due to the emissions, it should never face a building. This is because its fumes are toxic. It needs coverage in the rain.

Portable Power Station

This is more of a giant battery pack than a generator. This power station operates on a battery or solar panel. This is why it requires charging. It does not need gas at any point. Hence, it is safe for indoor purposes. Also, it generates less power than other models. This device is not a smart long-term backup. It is affordable and easy to transport.

Standby Generator

This is different from a conventional portable generator that is not installed permanently. It is "ever-ready" to provide power anytime there is a grid-off. It requires an expert to handle the installation. This implies that it runs automatically. This means it instantly kicks on with no manual intervention when there is a power outage.

One advantage of this model is its capacity to power an entire facility. It is a large generator that can carry bigger appliances. Also, it is relatively affordable; though, some are sold at exorbitant prices. It can run for days without any refueling.
