Inverter Generator Advantages – Disadvantage and Buyers Guide
Inverter generators can keep your home warm in the winter or excellent in the summer when the power goes out. It can also keep your food cold, kitchen cooking, and your computers and phones charged. The inverter generator’s advantages are many, as are the disadvantage.
Once upon a time, having a generator on hand was a valuable precaution to take in an unexpected power cut. On the other hand, generators are becoming increasingly necessary due to power outages caused by severe weather. Based on data provided by the government and utility companies, Climate Central, a non-profit news organisation, concluded that weather-related power outages in Australia have increased by approximately 69 per cent over the previous decade.
Generators can be deadly if not used appropriately
However, even though a generator may save your life in an emergency, misusing one can put you in harm’s way. In the days leading up to major storms, many people buy generators. While they are working by flashlight, they might forget to take essential safety steps during the setup process if they hurry to get the power on. Every year, carbon monoxide poisoning caused by generators is responsible for the deaths of dozens of people and the severe injuries of many more.
We do not wish you or anyone else dependent on a generator to be counted among those individuals. Always use a generator outside, at least 10 metres away from your house. Also, before you start a generator inside your home, check to see that your bedrooms and the rest of the house have carbon monoxide detectors that are in good working order.
The typical procedure for testing generators
Engineers load up each generator model with essentials that a person might want to power during a power outage. Such as a space heater, refrigerator, or window air conditioner. This allows them to test the performance of the generators. They check that the generator can handle the load that it claims it can, and they also determine what takes place when there is an abrupt increase in voltage. For example, if a refrigerator compressor is turned on when a generator is already at or near capacity. While some models bog down or even stall when faced with this challenge, the best ones handle it with ease. Consider how simple it is to move and operate a generator, how effectively it burns gasoline, and how long it can operate on a single fuel tank.
Every generator is tested through a series of scenarios designed to simulate how a user might unintentionally abuse a generator. Testing takes place in a vessel built specifically for the purpose on the premises of a testing facility. The vessel is wired with calibrated carbon monoxide sensors when a generator is turned on. These sensors record the CO levels throughout the container. Additionally, the speed at which each generator shuts off when the levels reach a potentially dangerous threshold is noted.
When you buy a portable generator, the relevant standard that it should meet is the Australian AS/NZS 3010: 2017 Electrical installations -Generating sets standard.
Recognize the Order of Your Power Priorities
The power output of generators, measured in watts, is how they are priced and sold. The power they deliver will determine how many electronic devices and appliances you can operate simultaneously; a typical home will require approximately 5,000 watts. The power delivery and quality, both evaluated and rated as part of our generator ratings, determine how efficiently they will operate. When it becomes bogged down, a generator with high output but problems with the delivery or quality of the power might stall or trip a circuit.
Compiling a list of the necessary things for you if the power is out. After that, you should add up the wattages of each item on the list. Here are some approximate prices for some everyday necessities:
Refrigerator: 600 watts
Between 750 and 1,500 watts for a sump pump
1.500 watts of power for the portable heater.
Air conditioner for the window: one thousand watts
Lighting: five to eighty watts (per bulb)
60 to 300 watts are required for a computer.
Considerations Regarding Specifics
Do not be kept in the dark by the wind or rain. Take all of these choices to purchase the generator that is most suited to your requirements.
Automatic Cut off of Carbon Monoxide
Suppose a built-in CO sensor detects levels of the deadly gas building up to certain levels. In that case, this essential safety feature will automatically turn off the generator’s engine. Suppose a portable generator wants to make it onto our list of CR recommended generators. In that case, it needs to have this feature, and it also needs to pass Consumer Reports’ safety tests. There are now more models available from more manufacturers than ever before.
Among them are industry heavyweights such as Generac, Honda, and Ryobi. Our ratings include more than a dozen generators equipped with a CO safety shutoff. You might come across marketing terms like “CO Guard,” “CO Protect,” “CO Detect,” “CO Shield,” or “CO Sense.” These terms all refer to carbon monoxide protection. It is possible to determine whether or not a generator satisfies one of the two standards by checking the packaging and looking for one of the following certifications:
Low-CO Emissions Engine
An additional safety feature that manufacturers like Ryobi and Echo are incorporating into their products is to protect users from the dangers of carbon monoxide poisoning.
The generator will start up automatically if the power goes out, so you won’t have to do anything. When working away from home or travelling frequently, you may not be able to always get back quickly in an emergency; this can be problematic.
Automatic starting is available on stationary models. This hassle-free alternative to pull-starting the engine is available on a few different portable models with the push of a button. If the battery is not included, you will need to factor in the additional cost, typically around $50.
Alternative Fuel Capacity
Most portable models can only function when fueled by gasoline; however, some come pre-fitted to use a propane tank or natural gas line. Others can be converted using conversion kits.
A helpful device, you can see at a glance how much fuel is still left in your portable generator, particularly during extended power outages.
Low-Oil Cutoff Switch
The generator will power down if the oil level drops below a certain threshold to avoid damaging the engine. It is a feature that is typically standard on stationary generators, but it is becoming increasingly common on portable generators.
If you have four or more, you can better utilise the wattage by spreading out the load; however, we recommend only using these in an emergency or away from home, such as camping. Regarding transfer switches, please see the following section.
This connects to the generator so that you can plug in appliances without having to run extension cords outside, which can be a potentially dangerous activity.
Different kinds of generators, including inverter and non-inverter
You have the choice between four different paths. Standby generators for the home are permanently installed, can operate on either natural gas or propane, and turn themselves on when there is a power outage. Portable and inverter generators can be moved from one location to another. Available in a variety of sizes.
Portable power stations have large batteries that store electricity when you need it. Some are more suitable for carrying to a tailgate. In contrast, others are more suitable for being stored on your property and used as an emergency power supply. This is the only option for someone who lives in an apartment, for example, and cannot run a generator safely outside.
Inverter generators are significantly less noisy than their conventionally powered equivalents. Because they adjust their output to meet the requirements of the load rather than maintaining full power at all times. These models typically have a higher price tag than traditional portable generators with outputs that are comparable because their engines are more complicated.
They have more advanced exhaust systems, which help reduce noise and reduce emissions. In general, models provide anywhere from 1,500 to 6,500 watts. They produce fewer emissions and run more efficiently than portable generators. However, you should still take all safety precautions with a portable generator.
The average price range is between $300 and $4,000.
Mobile and movable generators
The price of these units is typically lower than that of home standby generators. Gasoline is typically what powers them, and you might need to keep a significant supply of it on hand. If you want to store your fuel for a more extended period, you need to add a stabiliser. You are free to use portable generators anywhere on or off your property. Still, you should never do so inside a closed-off room or building. These models can produce lethal levels of carbon monoxide in a short amount of time.
Always operate a portable generator at a distance of at least 10 meters from your home and any equipment. Such as a central air conditioner condenser or a window air conditioner. Always direct the exhaust away from your home or any other structure, including your neighbours’ homes. Protect your generator from the elements by covering it with a canopy specifically for your model. There are a few of these models that come with an electric starter. Models are generally 3,000 to 8,500 watts. On the other hand, the battery necessary for the electric start might not be included.
Costs typically range from $400 to $2,500.
Home Standby Generators
These models are the most expensive and should only be installed by a trained professional (so factor in labour costs). When it comes to town or municipal permits, noise restrictions, and the ideal location, an experienced electrician can be of great assistance. These start-up on their own whenever there is a disruption in the power supply. And they typically provide more power than the other four options.
They perform an internal diagnosis and alert you when maintenance is required on their own accord. Some people will even do this to you or your dealer via email or text message. Propane, which requires fewer safety precautions to store than the gasoline required for the other models presented here, or natural gas. Which offers an endless supply of power are the two fuel options available. They can be anywhere from 5,000 to 20,000 watts in total power.
The typical cost ranges from $2,000 to $12,000; however, this does not include installation fees, which can double these figures.
Mobile Electrical Recharge Stations
These machines are powered by a battery that an electrical outlet can recharge. A solar panel is also included (you might also see them referred to as “solar generators”). Neither gas nor propane is used in their operation.
The introduction of portable power stations has only occurred relatively recently. The price of these units is typically higher than that of portable gas generators. Because they lack an engine, these devices produce almost no noise, which should reassure anyone worried about that issue. Because they do not generate any fuel emissions or carbon monoxide, you can use them anywhere inside.
They don’t provide power in the exact quantities as portable generators. You shouldn’t expect to power as many appliances or run them with electricity or solar power for an extended period. This is because you can’t keep them running without recharging them. There are no issues with starting because there is nothing to start; these power stations are like a larger version of a battery pack that you might use to charge your cell phone. There are no problems with starting because there is nothing to start. The power range of the models we test is 1,200 to 1,500 watts.
The average price range is between $750 and $3,000.
Innovative Measures for the Protection of Portable Generators
To lessen the likelihood of an individual becoming poisoned by carbon monoxide. Many of the most recent models of generators come equipped with a sensor. If present, that will cause the unit to turn off by itself if the concentration of CO in an enclosed area rises to a level deemed hazardous. This safety feature has a good chance of preventing deaths. Some of these models also have engines that produce less CO in the first place.
Even if your generator has this potentially lifesaving feature. We still advise you to follow the safety guidelines when using a generator. You should direct the exhaust away from any windows, doors, air conditioners, and other structures. You should always do so at a distance of at least 10 metres from your house.
Have you thought about getting a transfer switch?
What exactly is that? It utilises a single cable to provide a secure connection between your circuit panel and a home standby or portable generator. If you do not have one, you will need to use extension cords. Also, extension cords can be hazardous. Because it is simple to overload an extension cord, which can cause it to overheat and start a fire.
Additionally, a transfer switch offers a great deal more convenience. Your home’s entire circuits can be powered without the need for extension cords when you have a transfer switch installed. If you rely on extension cords, you only power items that have a plug. Connect them to your generator using heavy-duty outdoor-rated extension cords. This enables you to use freely essentials that do not have a plug, such as overhead lights, well pumps, and water heaters.
We suggest you have a qualified electrician install a transfer switch for you. You should be prepared to pay anywhere from $500 to $2000 for the labour associated with the installation. When using a stationary model, the transfer switch will start operating – if the power goes out. Thus, you will need to manually toggle a few switches on any portable models you have.
Restoring the main power of use can be problematic
Most transfer switches are constructed for an input voltage of 240 volts. This indicates that you will need a generator at least 5,000 watts in size. Stationary models turn themselves off when the power is turned back on; however, portable models require the same switches to be flipped in the opposite direction to restore live power.
Remember that you’ll have to decide which circuits are connected to the transfer switch before using it. One piece of advice that will simplify prioritising tasks is to examine your electrical panel and locate each circuit breaker. Then labelling the outlets and appliances controlled by that particular breaker. The simplest method involves purchasing a compact electronic tool known as a digital circuit breaker finder. Which can be had for less than fifty dollars. You will be able to ensure that the electrician connects the circuits for all of your necessary items in this way.
Do you want to spend less money? Instead of installing a transfer switch, you should have an interlock device installed. This device allows you to power your home’s entire circuit breaker panel with the generator. It costs less and can be set up in a shorter time by an electrician. However, it also prevents you from running the generator while receiving power from your utility company once they have restored your electric service. This is significant because if you operate a generator while also receiving power from your utility company. You risk damaging your electronics and possibly shocking a worker performing maintenance near your home.
