What is Inverter Generator?

Having similar basic purpose to other types of generators, an inverter generator is amongst the essential tools to own to provide backup or additional power source. For example, it provides extra power in the event of power outage caused by natural disaster, as safety net and support your household by keeping various appliances running. It ensures that you still have plenty of power boost for electronic and entertainment devices such as refrigerator, lights, or even smartphones.

That being said, this particular type of generator is a different breed than its counterparts that you’re probably familiar to already. The similarity lays in the fact that both use fuel in the form of gasoline, propane, or diesel to convert to usable electric power.

To provide ready-to-use power, an inverter generator use inverter that’s controlled by computer system. It results in a more efficient, lighter, and quitter operation than other generator types. In addition, it makes sure that the produced power has less fluctuation, more or less similar to regulator. The power that being inverted is cleaner in general, which is essential if you were to use it as recharging station for sensitive electronic devices like laptops and phones.

A power inverter may come in various designs and sizes, just like the conventional generators. It means some models might have better or more specific features from others. Knowing what it takes to consider a model as a high-quality product and being able to compare their differences is the key to find the most suitable model for all of your power needs.

The Power Quality of Inverter Generator

the power quality of inverter generator

A power generator – whether it is a standard, conventional, silenced, diesel, or petrol ones, has similar working mechanism. It basically has engine that connected to AC alternator with fixed speed no matter what load is being used. The engine will use more amount of fuel while working at the same speed when the load is increased and vice versa. The windings of main alternator are directly connected to the load.

Now, note that the principle above doesn’t apply to an inverter generator. It’s true that engine on this type of generator is still connected to alternator to produce electrical power. However, an inverter use rectifier in order to convert AC to DC power, then it’s being smoothed out by capacitor, which then inverted to the AC type of power back. As the result, it generates independent power more consistently regardless of its engine speed, along with cleaner energy compared to conventional generator.

The modern electronic products and appliances today such as TVs, computers, smartphones, or printers are mostly using microprocessor. These devices have sensitive quality, that’s why using power sources with unstable voltage or frequency may result in failure or damaged devices that cannot be repaired.

The Difference between Inverter and Regular Generator

inverter generator

Choosing inverter generator is all about its power capability and where do you need to use it – at home during outage or for outdoors activities such as camping, tailgating, or an RV trips. With enough capacity, any regular generator, inverter or not, will do the job well. However, it is important to note that such small generators sometimes aren’t capable to handle bigger jobs. If you pick generator with less than 2000W power capacity, chance is, it will have trouble to run big appliances such as air conditioner or refrigerator.

In order to start, motors need almost six times power as it needs to run. For an instance, a standard household regulator requires 2700W to start but only need 900W to run. This starting power measurement is also known as the maximum watts or surging watts, and it is what mostly used by companies to name their inverter generator products. It is the opposite of regular portable generator which usually named by its running power capacity. Here are the examples:

  1. A 3500W power inverter usually has 3500W surging power and 3000W running power capacity.
  2. A 3500W power portable usually has 4500 surging power and 3500W running power capacity.

Another thing that makes power inverter and power portable different is their power quality, which has been explained above. Having clean power source is important if you’re going to use it for electronic items such as smartphones or laptops. Some portable generator may disrupt the alternating current signal to a concerning degree, reaching up to 25% THD (Total Harmonic Distortion) which can lower down depending on how heavy the load is used.

Majority of inverter generator models generates highly stable clean signal, with less than 3% THD. This number is even typically the worst scenario. Just take a look at the products’ output specification to find out. That what makes the power inverter is more preferable to regular generators.

The Key Features of Inverter Generator

The possibility of difference in terms of how a generator is used and designed is depending on how it runs. Read an overview that briefly explains how inverter generator differs from standard portable generators in several points available below.

  • Power inverter doesn’t need installation cost or take up much spaces.
  • It doesn’t emit smokes or fumes.
  • It is much easier to operate than standard generator.
  • It produces much lower noise level than standard generator, even though it’s not completely without sound. (Read also Quiet Generators)
  • It has excellent portable design, which makes it easy to move and store anywhere – no need to worry about bringing it to busy and crowded environment.
  • It runs on batteries on some models, which mostly included on the purchase.
  • It generates cleaner sine waveform. Standards generator directly connects AC alternator to the load without any further execution, whereas inverter generator converts the output in AC to DC to AC back, resulting in far more stable, cleaner, and better-quality power that eliminates any shock or damage possibilities to your appliances.
  • It is designed with more modern appearance than conventional generator.
  • The majority of inverter power model is equipped with economy mode operation to work more efficiently, which requires lower power and use less amount of fuel.

The Advantages and Disadvantages of Inverter Generator

As with any other product in the market, inverter generator has its own share of upsides and downsides. You can look at some of them below.

Compact design and lightweight body

The technology of power inverter makes it possible for companies to design highly compact and super light body frame, which is ideal to bring for outdoor uses. In general, power inverter can provide similar efficiency as conventional generator at half of its size. You can find a lot of models that incorporate ergonomic handle to practically carry it anywhere, but also packed it away when not in use.

More stable power with better quality

Don’t let yourself be fooled with their small size, as power inverter can giver better power quality than the conventional generator. The clean power it produces and the absence of fluctuation are probably the best features to get from this particular unit. No need to worry about sudden surges power that will damage and crash sensitive various sensitive devices.

High efficiency of fuel

Inverter generator is generally not a gas-guzzler machine. It runs effectively, meaning with less money you can get more power. It can automatically adjust the engine speed to match with applied load, to optimize the fuel efficiency while maintaining the supply. The outcome is longer runtime continuously, with stable power and frequency for your appliances.

Lower noise production level

The generators made for camping are notorious of producing loud noise, which may cause inconvenience for people around you. However, with inverter technology, it is no longer an issue. This type of generators doesn’t need to run at full speed constantly, thus it is far quieter than its traditional sibling. In addition, most models are designed with muffler, insulator, and sound-proof casing to minimize the noise level.

The main disadvantage of using power inverter is the expensive price tag. Inverter models are typically pricier compared to other types of generators such as standby and portable models. Even though the initial cost might be higher, you can be assured that its operating costs in total are lower. This total cost is already including the fuel and the maintenance costs as long-term investment.

Another downside that you have to consider is the clear contrast of the power output between inverter generator and other generator types. Inverters generate power in range of 1,000 to 4,000 watts, whereas other generators may produce power in range of 500 to 50,000W. Therefore, inverter power might not be the best option for you to choose if you were to use it for heavy-duty and large equipment with higher power requirement.

Buying Guide to Pick the Ideal Inverter Generator

Before you purchase any type of product, especially a valuable one that you’re going to use in long period of time, it is important to gather the information about them to make a sound buying decision. There are so many models of inverter generator in the market, so you have to narrow your options. Here are several tips to follow to help you pick the ideal model:

The required amount of power

Choosing the perfect generator size for you, as its surging watts and running watts, is depending on the type of appliance that will be powered. Surging watts are the initial amounts of watts needed by motor-based products to run for couples of seconds. It is the maximum wattage that can be generated. Meanwhile, running watts are the constant watts required to keep the appliances or devices to run.

The period of run time

Looking for how long a generator can run in half-load is the best way to select a model. The longer its run time, the less frequent you need to fill the fuel. Picking power inverter with minimum 10 hours at 50% load can guarantee you to get full sleep at night.

The amount of outlets

It is important to pick an inverter generator that has decent amount and the right type of outlets. To run larger item with higher wattage requirement such as air conditioner, select generator that has 30-amp twist lock outlet.

High portability

Even though portable generator is made to be carry around easily, it can be quite heavy. Power inverter is typically lighter. Some models are even designed with wheels and folding handles to make it easy to move and store around.

Plug cord set

Several models of generators are equipped with heavy-duty cord set. A cord set costs less than $90 and can provide power for four household appliances with single cord, to eliminate the necessity of numerous extension cords.

The maintenance levels

Just like all machinery items, inverter generator needs to be stored and maintained properly to ensure that it runs well and has long lifespan period. Search for detailed maintenance review of a model, or ask the seller about the maintenance a model required.

The brands

Not all power inverters are made the exact same, in fact, there are large differences in terms of quality in an array of selections. A renowned name such as Honda might be more expensive than others, but provides strong and reliable performance. However, the brand doesn’t need to be the main consideration when making a purchase decision for a generator.

The given warranty

Warranty is a big giveaway if you’re trying to know how long a product will last. When a product comes with long warranty, chance is, its manufacturer is confident with the estimated period that exact generator will last for its users.

Maintenance Tips for Inverter Generator

Proper and consistent maintenance are the keys to have your inverter generator to last longer. Planning in advance on how you can optimize the most out of an investment is the easiest, most powerful and safest way to make sure that the product can be counted anytime. Below are several helpful tips to maintain your power inverter.

1. Operate the engine at regular interval of time

Generator is a machine after all, and a machine has to be used properly to work well or else they will rust. Most manufacturers advise to use generator in periodic intervals, with each run spans for half to an hour long to charge the electric starter that uses battery.

2. Have supplies of oil and filter

Brand new generators typically need oil change by the next 25 hours. From there, you have to refill the tank and throw the old fuel away once every 50 to 60 hours. That’s why it’s better to have oil and filters prepared in advance that can last your generator for at least couple of days.

3. Regularly lubricate the engine

While shutting off the inverter generator, you have to examine the engine oil each time. Oil that stored at the top part of the engine must be drained back to keep a track of its classification and viscosity. Keep the level of oil always in the full as best as you can.

4. Keep the batteries in sharp check

Weak or even dead batteries are amongst the most common reasons of failure in generator system. To ensure that your machine is running properly and well-maintained, it is essential to ensure that the batteries are on fully-charged condition. Doing regular examination of battery status is highly recommended to prevent hiccups.

5. Make sure the fuel is not running out

Do not ever let the generator runs on dry fuel tank. If the fuel tank is running out of gas, the power will stop. In addition, the electrical load of the connected appliances will draw the magnetic field from the generator. So, make sure that you have the tank filled before using it.

6. Drain out the remaining fuel

Upon purchasing a generator, having fuel storage must be one of your main things to consider. In case you use the machine and it has some fuel left in the tank, it must be drained that the next time you refill the tank it is already in empty conditions. Fuel as short stored life, especially gasoline – if they get deteriorated, there is a possibility of contamination that can damage the generator’s engine.

7. Utilize stabilizer for fuel

As it is stated in previous point, fuel can carry contamination that causes damage to the inverter generator. It might happen if the generator didn’t operate for a long time. This may create unwanted condition over the performance when you want to use the generator. A good way to prevent this issue is by investing on fuel stabilizer so the engine can work properly as it should.

Safety Tips to Use Inverter Generator

Here are several useful tips to follow in order to use your inverter generator safely.

  1. Always run your generator in open setting with a lot of ventilation around. As the engine produces deadly carbon monoxide, it’s not safe to be operated inside building, garage, or home.
  2. Never plug it to the wall socket to prevent back feed. Only use heavy-duty cords to connect the outlets in generator with your appliances.
  3. Have the generator already turned on before you plug any appliance or device. To prevent overloading condition, turn or light the appliances one at time. Keep in mind that generator is mainly used for temporary purpose so make a priority.
  4. Generator carries electrical risk, and the risk is elevated if it runs on wet situation. When the weather creates moist or wet circumstances, use the machine necessarily. You can protect the unit by having it operated on dry surface and canopy structure over in open spaces so water will not drain or form puddles underneath. Make sure you only touch the unit with dry hand.
  5. Ensure that the engine it shut off and already cooled down before refuel it.
  6. Keep the inverter generator unit away from children and pets. Most components inside the machine retain heat that might burn anyone who touches it when running.

It is true that generator is a handy equipment to have in times of power outages. However, whether it is an inverter, portable, or standby generator, they can pose danger if they are not operated properly. It is best to always read and follow the instruction from manufacturer, ask qualified electrician or the vendor if you’re having certain problem to run the machine.

Final Conclusion

Buying a compact-sized generator is considered as lifestyle option. You need to base the purchase decision based on your specific portable electricity needs. From tailgating party, camping trip, to fishing over the weekend, this equipment can provide you reliable, efficient, and quiet electricity supply.
