What is Portable Generator?
Portable generator is equipment that’s specifically used to provide temporary and transportable source of electric power. It is a common device to be found on job sites, leisure areas, and even household. Here are several basic uses of this machine:
- Extended power outages or cuts
- Construction and building sites
- Outdoor activities such as festivals, camping, or hunting
- Home, garden, and park uses
- General auto repair and DIY project purposes
- Onboard power sources of boats
- Temporal pop-up stores and impermanent installations
The capability of portable generator is rated by the generated power it can produce in watts unit. The more watts it has, the more electrical devices you can power up with it. There are two watts types out there:
- Starting watts: the peak power and required amount to start running motor-based items
- Running watts: the constant power produced to keep the electrical items to run
How Does Portable Generator Work?
The best way to explain and understand how portable generator operates is by focusing on the core components and their basic overview. It is possible to see this equipment as a complex machinery piece if you’re not familiar with it, but the key parts are actually relatively simple.
Even though there are so many different brands and models available as options to purchase all around the world, the basic principle of how portable generator runs is practically the same. Whether the machine is powered by gasoline / petrol or diesel / propane, majority of the important parts that make it work do not vary much. In general, here are the parts that you need to be aware of:
- Internal Combustion Engine (ICE)
- Alternator or generator head
- Generator starter
- Control panels and devices, such as power outlets
- Fuel tank
- Protection or safety devices
In the most basic explanation, here is the summary of how a generator machine works in the simplified steps:
- Fossil fuels are entered into the fuel tank. It is typically gasoline or propane – even though the larger machine usually used natural gases. Generally, the fuel is inputted through safety tube, but in smaller models may use funnel.
- The gas or fuel liquid inside the fuel tank provides source for combustion energy to run, after you begin to operate the machine. Portable generator starter can be a manual pull cord or electric push button. As long as the fuel source is available, the engine would be able to run.
- The built-in generator head or alternator is transformed by internal combustion engine. It converts rotational motion as mechanical energy into electricity power. The generator head is basically comprised of drive shaft that’s linked to the engine that will spin electromagnet within coil to produce and utilize electric field.
- The produced electricity is transformed into practical voltage or wattage by regulator then. The useable electric power is sent into the power outlet on the generator. By then, the power can be sent through standard cables and plugs into various electrical devices that are connected to the portable generator.
Some components might vary depending on the manufacturer, model, version, and size. For example, some models might incorporate extra systems such as exhaust and cooling features, exterior machine frame, or lubrication pipelines.
Portable Generator vs. Standby Generator
To decide whether you should opt for standby or portable generator, here is the list of features from each type:
- In terms of cost, this unit is pricier than a portable one. It also should be installed by professional, which will require labor costs. Depending on local law in your area, there might be specific regulations about proper location and noise restrictions.
- A standby generator starts automatically at times of power outage. It typically is able to supply more amount of power than portable unit.
- This type of generator runs self-diagnosis to allow you now if it needs maintenance. Some models even able to inform you by text or e-mail.
- There are more options when it comes to fuel, whether you want to use natural gas, gasoline, or propane to provide supply of power.
- The power capability ranges from 5,000-20,000 watts.
- A portable unit tends to cost less than standby type of generator.
- It usually runs by using gasoline, so you might want to store in abundance. For extended storage, the fuel needs to be added with stabilizer.
- As the name implies, the generator can be brought anywhere, inside or outside your property with exception of enclosed space, because it can produce harmful levels of carbon monoxide. Make sure to run the portable generator at least 20ft away from your building and electric equipment such as window AC or central AC. Turn the exhaust to face away from any building structure.
- Protect the generator with a canopy that specifically designed for your unit model when it rains.
- Some models feature electric starting mechanism, so they will require battery.
- The power capability ranges from 3,000-8,500 watts.
Types of Portable Generator
As there are a great number of portable generator types that available in the market, it is important to find a model that will suit with your power supply requirement and intended use scenarios. Below, four different types of this unit will be explained:
1. Quiet portable generator
In general, it’s already known that generator is a practically noisy machine when operating – even though the technology advancement in recent years has made it possible to lower the sound levels in with dramatic improvement.
A quiet portable unit is typically sold in more expensive price range compared to the more affordable but noisier models. Inverter type of generator tends to be on pricier side, considering that it usually is designed with more compact frame. This type of portable generator unit has smaller body yet works more efficiently so it can generate the equivalent amount of electricity power as its counterparts.
Majority of inverter generators also has full enclosing frame that has sound dampening quality. It makes them able to operate much quieter than the conventional open frame model design – which lets sound vibration to escape at much higher levels naturally to its surroundings. Besides, they also tend to be lighter and smaller to carry than standard generator models, due to the reduction in the size of its engine.
2. Household portable generator
A portable unit that designed for household usage purpose is commonly kept for occasional events such as electricity cutouts in temporal period. It is usually only operated in case of extended power cut and possibly utilized for that purpose for once or twice throughout the year.
There are numerous portable generator models that designed and sold for this exact occasional purpose in mind. Majority of the models are made to deliver lower power range and mostly marketed for few far and between usage, designated to power a basic appliance or two.
The most common targeted appliances to be powered by household generator in the scenario of power outages are lights, freezers, and fridges. Other equipment includes entertainment and communication devices such as TV, computers, laptop, or phone.
To find an ideal purchase for occasionally used household generator, it is important to calculate the total required power for the essential devices and appliances that you’d like to keep running. From there, you can choose the most compact portable generator that meets with power capability that you need.
Generally, the buying guide for outdoor portable unit is pretty much the same with the rules of thumb to buy household generator in prior point. The best way to approach final buying decision is by calculating the required power to keep your appliances and devices during outdoor activity to operating, then selecting the most compact alternative that meets with all your needs and preferences.
When you’re about to buy portable generator to use on motorhomes or caravans, an additional feature that’s important to consider is its noise level. Be mindful of the different sound levels that produced by different models because not all of them are suitable for the outdoor environment purpose. Some recreation sites may not allow you to bring louder and bigger generator due to the noise restriction regulation.
4. Portable generator for boats
Boats with larger body frame and engine will have equivalently large power generator that installed permanently. However, it is different for smaller boat craft. It opens the market for smaller sized portable power generator unit that designated for boats with modest size.
Keep in mind that the portable unit itself should not be operated or fuel filled on board, or anywhere close to the core engine of the boat, due to the high risk of electrocution, fire, or buildup of toxic fume. Once again, it is necessary to calculate the amount of power output that you require in various scenarios while you’re on the boats so you can find the perfect model unit that’s match with your needs.
How to Choose Portable Generator
Here are some advises regarding portable generator buying considerations:
1. Delivered Power and Multiple Outlets
The required power is the first thing you need to find out and calculate before buying a generator unit. For example, you might only need 700W to run your refrigerator, but what if it requires 2100W to start the appliance?
The types and numbers of outlets are also adding to the buying factor. An inverter generator with compact size probably will have a couple of 120V AC outlets and several USB ports. Any unit that has over 4000W capability might have 240V plugs in addition to a few 120V outlets. A 240V plug can be necessary to have if you want to connect the generator into panel directly. If the unit is intended for outdoor usage, try to search for models that have GFCI outlet protection.
2. Frequency of Usage
Majority of portable generator models that sold nowadays come with several years of warranty that benefits their users. Any models from reputable brans will do if you’re only using the unit for recreational use or emergency power.
On the contrary, if you use the generator daily to be run by a crew, it is better to select legitimate model that specifically designated for commercial uses. In addition of getting suitable equipment with your job, those models are more likely to give longer warranty that lasts years instead of months. Of course, they have more expensive price than the standard models.
3. Type of Fuel
By far, the most widely used type of fuel is gas. This is due to the reason that gas is commonly available everywhere except for particular circumstances such as major storm. That being said, diesel powered generators offer better fuel efficiency. It takes more money to upgrade, but there are various benefits to get, such as losing the frequently clogged carburetor for a convenient period of time. Diesel powered generator is also more suitable for household usage, even though it isn’t as commonly available as gasoline.
Propane portable generator is another great alternative to go. There are some model units that allow you to convert gas generator to propane use. It’s an ideal option to choose if you don’t mind a bit more complicated engine and environmentally friendly source of fuel.
A generator that’s powered by battery has benefit of being rechargeable by solar panels, omits zero emission, and operates silently. The disadvantage including the expensive price tag, long time to recharge, and in general cannot provide over 1800W of power. It is not the most practical option for outdoor activities such as tailgating and camping.
4. Fuel Tank Capacity
A fuel tank with larger capacity allows you to go longer before you need to refuel. Majority of portable generator runs 7-9 hours in average by using half load. If you use more it will last in shorter time and vice versa. Again, it might be the matter of needs and preferences but larger tank is more favored in common.
The material of fuel tank is not usually seen as a make or break factor for most people. However, just for further information, there are different of fuel tank material such as stainless steel and plastic which each has their own pros and cons.
5. Starting mechanism
Manual pull recoil starter is the traditional system that used by many older models – even though it’s still relevant nowadays. More modern models tend to use electric start, which may cost a bit more but works amazingly.
An electric starter requires battery, which means there’s a potential of leaked battery acid that commonly found in car. However, some models incorporate lithium-ion battery that’s safer. Make sure that the battery is already charged in advance on portable generator units with electric starter.
6. Noise Level
Quiet operation feature is more often to be found in smaller sized generator. Some model units even run quieter than normal conversation. An option for quite feature becomes rarer once you’re looking for 4000W category and above. Fuel source type may also affect the noise level as gas can operate more silently than diesel.
