How Do Portable Generators Work?
In order to understand how generators work it’s imperative to look at the various parts.
Portable generators feature a power generator head, a fuel source, an engine as well as power outlets. This is why they are sometimes referred to as gensets or engine-generator sets. Typically, these devices have the following components combined and enclosed in a metal frame:
- Fuel tank
- Internal combustion engine
- Power outlets
The generator head is the component responsible for producing electricity to the power outlets. The gen head is powered by the internal combustion engine, which runs on some kind of fuel, usually diesel, gasoline, natural gas or liquid propane. Regardless of the kind of fuel, the engine (often a 4-cycle), provides the mechanical energy needed to power the gen-set by spinning a shaft. The spin speed is maintained by a speed regulator or governor.
As with any mechanical process, cooling and lubrication are required in the moving parts in order to ascertain maximum efficiency. The gen head converts mechanical energy into electrical energy, which is then passed on through the power outlets.
Simply put, a generator moves a magnet near a wire coil in order to create a steady flow of electrons. This flow is harnessed and redirected to the outlets, thus providing electricity to appliances.
If physics isn’t your forte, not to fret as there’s an analogy that can help you better comprehend how this works with watts, amps, and volts.
A generator works like a water pump, but instead of pushing water through the hose, the magnet pushes electrons. Similar to how a pump applies pressure to water, a gen-set magnet pushes electrons and applies ‘pressure’ for flow.
These electrons move through a wire until they come into contact with a ‘load’ such as an appliance, which in turn creates heat or supplies the power required to run that device. The number of electrons in an electrical circuit is known as current, which is measured in amps.
Voltage is the pressure that pushes electrons, and it’s measured in volts.
Generators are measured by the amount of power they give out, usually referred to as watts.
As wattage goes up, so does the voltage and current. Watts are categorized into two- Running Watts and Starting Watts. The latter is the additional power required to start up the motor-driven parts while the running watts help to keep an appliance running.
And there you have it, a brief, non-complex explanation of how portable generators work. To ascertain optimum operation and safety, ensure the generator is placed outside. Most portable generators emit carbon monoxide, which is a health hazard. Before running the unit, take some time to learn how to operate it to avoid any risks that come with these devices.
How Do I Choose The Best Portable Generator?
A blackout will leave you without heating/air conditioning systems, refrigerators, freezers, lighting systems and water pumps – all the conveniences that make for modern living.
If the outages last for several days – like when caused by a natural disaster – your home could quickly become uninhabitable. The food preserved in your freezer will spoil, your security systems will fail, your sump pump will not work, your water pipes could freeze and burst.
Fortunately, situations like these can be avoided by investing in a top portable generator. While not offering the huge output and automation of a standby generator, this relatively inexpensive solution will let you continue living in relative comfort through any disaster-induced power outage. A good portable generator will allow you use your vital appliances and lights till the power is restored.
Portable generators are also needed for where power is not available like campsites, for outdoor activities, and work sites. The uses for portable generators are as varied as the number of models in the market.
There are some key features you need to consider depending on your intended usage of the portable generator.
And there are some general considerations that will help you get the right portable power solution.
1. How Much Power Do I Need?
A good portable generator should be able to comfortably run essential household appliances. The output power of portable generators is rated by startup watts (or peak power) – the momentary power boost required to start an appliances’ motor, and running watts. So before you purchase a portable generator ensure that it produces enough juice to handle the startup wattage as indicated for each appliance. If you want to know how big of a generator do I need we have written this guide.
2. Fuel Efficiency
It might be impossible to get fuel during a natural disaster. Hence, a portable generator that can give you the most hours on a full tank of gas is most desirable.
3. Running Time
Closely related to fuel efficiency, running time is the number of hours a single full tank can last. It has to do with the tank capacity and the size of the generator. There are powerful portable generators that can run for up to 11 hours nonstop. This is quite important if you need backup power all through the night.
Portable generators are designed to be moved around. But they are not all equal in this regard. The higher the output, the heavier the unit becomes. So if the intended usage for your unit requires constant movement, you should consider the weight and other features like handles and wheels that enhance manoeuvrability.
5. Conventional or Inverter Generator?
Conventional generators run on full, constant speed and can produce lots of power. But your sensitive devices are better off powered by an inverter generator because of the clean power output they generate. Also, inverter generators can adjust engine speed according to load, and are therefore more fuel efficient and run quieter – properties which make them better suited for recreational pursuits. More about traditional vs inverter generators here.
6. Safety Features
Because electricity can be dangerous, safety features are a must for portable generators. When choosing a portable generator, Insist on a unit with:
- Inbuilt surge protectors- which protects your appliances from voltage spikes.
- Low oil shutdown – a feature which shuts down the engine automatically when the oil is low to prevent permanent
- Spark arrestors – which stops the generator form emitting flammable particles that can cause fire incidences
- Built-in circuit protection sensor – to protect you from electrocution
7. Control Panel Features
Premium portable generators can be started with a push of a button. Other useful control panel features are multiple household plugs, transfer switch ready, voltage selector switch and an odometer which shows in hours how long the generator has run. A clearly visible fuel gauge is also a plus.
What Is The Best Portable Generator Brand?
The answer to your question “who makes the best portable generator” is Westinghouse.
And the best of the brand is the Westinghouse WGen5500 Portable Generator because it is an all round impressive unit packed full of features. A powerful, rugged machine that’s easy to use, totally reliable, runs quietly and is relatively cheap
