How to Choose the Best Power Inverter

Types of Power Inverters

There are two main types of power inverters: modified sine wave inverters and pure sine wave inverters.

– Modified Sine Wave Inverter

Modified sine wave inverters use a basic form of technology that is perfectly adequate for powering devices such as smartphones, tablets, small appliances, and even a breast pump. To use a modified sine wave inverter, plug it into your vehicle’s cigarette lighter. This type of inverter may not provide a continuous supply of electricity which is necessary for highly sensitive electronics.

– Pure Sine Wave Power Inverter

Pure sine wave inverters utilize sophisticated technology that protects sensitive electronics. This type of inverter is specially designed to produce continuous AC power just like the electricity in your home. So you can use this type of inverter to power a large laptop, stereo system, or medical equipment.

Wattage

The more wattage an inverter has, the more power it can generate. Most power inverters show continuous power wattage and peak or surge power wattage. The peak power refers to the maximum power the inverter can sustain for a short time.

For digital devices or small appliances, a 300/700-watt power inverter such as the BESTEK 300-Watt Power Inverter is an excellent choice for road trip adventures.

If you need to power appliances at home during a power outage, watch television in your RV, or hook up flood work lights from your truck, you will need a higher wattage inverter such as the Ampeak 2000-Watt Power Inverter. These types of inverters usually come with cables that hook up to your vehicle’s battery. Another thing you need to be aware of when using a higher wattage inverter is that a car’s battery may have problems with the higher wattage, but a truck or RV has a more powerful battery.

AC Outlets and USB Ports

Most power inverters have 1 or 2 standard AC outlets that you can use to plug in small electrical appliances or power tools, and 1 or 2 USB ports for digital devices. Just be careful when you charge multiple devices together for long periods as this can cause the inverter to overheat and stop working.

Cigarette Lighter Cable Length

While an inverter may come with a good-sized 16-inch long cable that you plug into your cigarette lighter, other types of inverters may come with an extra-long cable that allows you to charge devices from the back seat.

Safety Features

Whether the inverter powers digital devices or appliances, it needs to have a built-in multi-protection system that safeguards your electronic gadgets such as a fuse, cooling fans, or other Smart design features.

Inverter Generator vs. Traditional Generator – Which Is the Best Choice for You?

Inverter and traditional fossil fuel generators are both popular options for providing portable power. However, essential differences may make one a better choice for you than the other.

Inverter generators are a newer, more advanced technology — typically burning less fuel to produce cleaner power than ordinary gas or diesel generators. Unlike traditional generators, inverters adjust their engine speed to match the power demand, providing greater fuel efficiency and less noise.

When choosing between an inverter and a conventional fossil fuel generator, consider your intended use, power output, and consumption needs — and your budget.

What Is an Inverter Generator?

An inverter generator uses less fuel to generate stable power through advanced technology. By throttling fuel use to meet demand — instead of always running at maximum capacity — inverter generators can help save on fuel costs and reduce toxic emissions.

Inverter technology allows a generator to produce energy with less than 3% total harmonic distortion. In simple terms, this means the inverter produces more stable AC power than traditional combustion generators. It’s more suitable for sensitive electronic devices such as smartphones, laptops, and televisions.

Additionally, their advanced technology makes inverter generators lighter and more portable than traditional generators. They’re a viable option for camping, RVing, and other off-grid activities.

Benefits of an Inverter Generator

An inverter generator offers several benefits over a traditional generator, including:

Less Noise

Inverters have advanced technology that allows them to run at a lower noise level than traditional generators. This reduced noise level makes them better suited for use in residential areas, camping, and other off-grid activities where noise pollution is a concern.

Parallel Compatibility

Many inverters come with parallel compatibility, allowing you to connect two or more inverter generators together to increase power output. Increased power output is helpful for applications where you’re powering high-wattage appliances and multiple devices simultaneously.

Fuel Efficiency

Inverter generators adjust their engine speed to match the power demand, leading to greater fuel efficiency. You can typically run the generator for longer on the same amount of fuel, saving you money in the long run.

Portability

Inverters are usually smaller and lighter than traditional generators, making them more portable and easy to store. This makes them a solid choice for camping, RVing, and other outdoor activities where space is limited.

Low Emissions

The design of an inverter results in fewer greenhouse gas emissions and is more environmentally friendly than a traditional generator. However, they still can’t match the zero-emission operation of a solar generator like the DELTA Pro, which can run solely on clean, renewable solar power.

What Is a Generator?

Traditional generators are machines that convert mechanical energy into electrical energy. A generator provides an alternate power source during a power outage or allows off-grid use of electric devices. Backup generators are suitable for various applications in homes, businesses, and hospitals.

There are numerous types of generators available that run on different fuel sources. Examples include gasoline, propane, diesel, natural glass, dual fuel, and solar.

Gasoline Generators

Gasoline generators are widely available and used for various residential and light commercial applications. They’re typically less expensive than propane or dual fuel options and are easy to find at most hardware stores. Unfortunately, they leave you exposed to fluctuations in gas and can be more costly to operate than other options over the long term.

Propane Generators

Propane generators run on propane, a cleaner-burning fossil fuel that produces fewer emissions than gasoline and diesel. In industrial and commercial applications, consistency in power output often requires the use of propane. They’re also helpful for emergencies where power may be out for an extended period or off-grid applications. You can store propane for more extended periods than gas.

Dual Fuel Generators

Dual fuel generators run on two fuel types, such as propane (LPG) and gasoline. EcoFlow’s Smart Generator (Dual Fuel) is one example. The Smart Generator integrates seamlessly with EcoFlow’s DELTA Max and DELTA Pro solar generators to provide a last line of defense when solar power generation or storage is insufficient to meet your needs.

Even if you generate most of your electricity using solar panels, adding an advanced dual fuel generator to your home ecosystem gives you added resilience and additional options in case of an extended power outage.

Solar Generators

Solar generators use solar panels to convert solar energy into DC power and an inverter to convert DC into AC (household) electricity. Solar is the best option for those wanting to use clean, renewable energy. Solar generators are ideal for home backup power, camping, RVing, and other off-grid activities. You can even use solar power to completely eliminate your reliance on the electrical grid.

The EcoFlow RIVER 2 Pro is a prime example of a compact solar generator that offers electricity on the go. If you want a more robust energy backup solution, you can opt for a higher power output and storage capacity model like the DELTA Pro. RIVER 2 and DELTA solar generators come with a wide variety of solar panel options to meet your electricity needs without burning fossil fuels.

Key Differences Between Inverter Generators and Traditional Generators

Size

Inverters are more compact than traditional generators. They’re portable and easy to store, making them ideal for camping, RVing, and other outdoor activities where space may be limited.

Inverter generators can be as small as a shoebox and easily carried by one person. They can also be much larger if you require more power. Traditional generators are usually bulkier in comparison.

Weight

Inverters are also lighter than traditional generators. They typically weigh between 30-50 pounds (13-22 kg), making them easy to transport.

Portability makes inverter generators an excellent option for camping, RVing, and other outdoor activities. On the other hand, traditional generators can weigh up to several hundred pounds, making them difficult to move and transport.

Noise Level

One of the main advantages of inverter generators is their lower noise level. They are significantly quieter than traditional generators, making them ideal for use in residential areas, camping, and other outdoor activities where noise pollution may be a concern.

Inverters typically produce noise levels between 50-60 decibels, while traditional generators can produce noise levels of up to 80 decibels or higher.

Having said that, solar generators are even quieter than any fossil fuel-powered option with their nearly-silent operation. With few moving parts, a portable power station and solar panels can replace the constant roar of a gas-powered engine.

Maintenance

Inverter generators require less maintenance than traditional generators. They have fewer moving parts, and their advanced technology makes them more reliable. Inverter generators also often have built-in features such as automatic shut-off, which helps prevent damage and prolong the generator’s life.

Traditional generators require regular maintenance, such as oil changes, air filter replacement, and spark plug replacement.

Solar generators require practically no maintenance, as they don’t burn fuel and rely on a combustion engine.

Portability

Inverter generators are more portable than traditional gas-powered ones due to their smaller size and lighter weight. They’re easy to transport and move around, ideal for camping, RVing, and other off-grid activities.

Traditional generators burn through fuel more rapidly, leading to challenges with storing sufficient fuel for your off-grid needs.

If you opt for a solar generator, you’ll find the portable power station (PPS) compact and light enough to carry, ranging from 7.7 lbs (3.5kg) to just shy of 100 lbs (45kg). Pair the PPS with portable solar panels, and you have an excellent set-up for energy backup on the go.

Which Is the Right Option for You?

Ultimately, choosing between an inverter and a traditional generator will depend on your specific needs and intended use. For example, a conventional generator may be the better option if you need a heavy-duty machine and are okay with the added noise and maintenance. But an inverter or solar generator is the better choice if you need a portable and quiet electricity solution for camping, RVing, or other off-grid activities.

A solar generator is the best choice available if you’re ready to go green.

What is an Inverter Generator? How does it work?

A Portable Generator is a very important device nowadays. Whether you face severe power outages or need an alternative source of power in worksites or camping, a portable generator is an ideal device for the job. Are you planning to buy a new portable generator for your home needs? Then, you might have seen or heard of different brands and types of generators with different power ratings, fuel types, sizes, etc. But there is a new player in the town known as the Inverter Generator. The generator salesperson might be pushing you towards this type saying it is much better than other portable generators. He/she is right in a way. But what is an Inverter Generator? How does it work? What are its advantages and disadvantages?

Before investing in the generator, it is ideal to understand a little bit about it. So, in this guide, let us know about inverter generators from a beginner’s perspective. To understand the basics and working of an Inverter Generator, we will be constantly comparing its operation with a traditional portable generator.

What is an Inverter Generator?

An Inverter Generator, as the name suggests, uses “Inverter” Technology to generate electricity, thanks to the high-amperage solid-state devices. Inverter Generators are usually small and compact portable generators that produce clean and stable power.

While you can get portable generators with very high power outputs (10,000 Watts, 12,000 Watts, or even higher), the power output of inverter generators is usually up to a couple of thousands of watts (3,000 to 4,000 Watts).

In a traditional portable generator, the main components that generate electricity are an internal combustion engine and an alternator. Things are slightly different in an Inverter Generator.

Even Inverter Generators have an engine and an alternator. But unlike traditional portable generators, they are not two separate entities but rather a single compact unit (helping in the overall compact design of the generator).

In traditional generators, the output of the alternator is AC which is available through the ports. You can plug your appliances directly into these receptacles or use a generator-grade extension cord and power devices.

Coming to Inverter Generators, the AC output of the alternator isn’t directly supplied through its ports. First, this AC electricity is converted to DC electricity. Then, the DC electricity is “Inverted” back to AC. This AC supply is available as the output of the generator. But why all this conversion and inversion?

How is it Different from Traditional Generators?

The AC electricity produced by the alternator of the traditional portable generator isn’t, technically speaking, clean (when we compare it with the utility’s supply).

On a macro level, the output waveform of the generator’s electricity is still a sinusoid. But when you dig a little bit deeper and look at things at a micro level, the sinusoid doesn’t look very clean with several spikes and distortions.

An inverter generator doesn’t provide the output of the alternator directly. It first rectifies the AC signal into DC Signal. The DC Signal is then inverted back to AC Signal.

Hence, the inverter generator takes the “dirty” power from the alternator and converts it to clean power.

How an Inverter Generator Works?

Here’s a simple explanation of how an inverter generator works. The main source of power in the case of an inverter generator is a fuel-burning internal combustion engine. Speaking of fuel, gasoline is the popular choice but propane is also quite common.

Regardless of the type of fuel, the internal combustion engine burns it and converts the energy into rotational energy (by rotating a shaft).

At the other end of the rotary shaft, we have the alternator, which converts this rotational energy into electrical energy (electricity). There is a lot of electromagnetic theory involved in the working of an alternator and we made a separate article on this topic.

The output of the alternator is, well, an alternating current or AC. A rectifier circuit takes this AC and converts it into DC (Direct Current).

Next, the DC Signal passes through an Inverter Circuit, which “Inverts” the DC Power back to AC Power.

If you are familiar with computer UPS and Home Inverters, this is exactly what happens there. There, the DC Power of the battery is “inverted” to AC. Here, instead of the battery as source of DC, the inverter generator converts the AC from the alternator to DC using rectification.

As the inverter circuit implements an intelligent microprocessor system, it keeps track of the frequency and voltage of the output AC Power. If it finds any variations or deviations, it immediately makes corrections to produce clean and stable AC Power.

This AC Power is available through the outlet ports (receptacles) on the front panel of the generator. You can plug all your devices and appliances here and run them.

Control Unit in Inverter Generator

An important part of the inverter generator is a special circuit known as the Control Unit. The job of this control unit is to monitor the power demand and automatically adjust the speed of the engine so that the generator produces the right amount of power for the load. This helps to improve fuel efficiency and reduce noise.

This kind of system is absent in traditional portable generators. Hence, the engine in those generators runs at a constant speed regardless of the power requirements of the load.

Key Points about Inverter Generator

Now that we have seen what is an Inverter Generator and how it works, let us understand a bit more about Inverter Generators.

Clean and Stable Power

From the above discussion, it is clear that the output of an Inverter Generator is very clean and stable. But where is this useful?

All modern electronics with Switching Power Supplies such as computers, laptops, TVs, power adapters for smartphones, tablets, and other sensitive devices need clean power without any spikes or surges.

If you plug these devices into the output ports of traditional portable generators, then there is a chance that the “dirty” power from the generator can kill the power supplies in those electronic devices.

But the output of inverter generators is very clean. The voltage and frequency are also stable. Hence, you can plug in all your sensitive electronics without fear of damaging or destroying them.

Varying Engine Speed

Another important feature of the Inverter Generator is its ability to vary the speed of the engine depending on the size of the load. If you have a 2,000-Watt Inverter Generator, you may not necessarily use all the 2,000 Watts from it all the time.

Depending on your requirements, you will plug and unplug the devices and appliances from the generator. What we are trying to say here is that the amount of load is not constant but varies from time to time.

If the load is not constant, why should be the output power of the generator? This is where the variable engine speed on Inverter Generators come into play.

In traditional portable generators, the engine speed is usually fixed regardless of the amount of load connected to the generator. But in Inverter Generators, a special module in the generator monitors the load, and depending on the demand (or lack thereof), it adjusts the speed of the engine.

This greatly improves the overall efficiency of the generator. The fuel consumption of the inverter generator reduces due to varying engine speeds. With low fuel consumption, the runtime of the generator improves greatly.

You can run the inverter generator on a single tank (or one tank of propane) for a really long time depending on the load you connected to it.

Another key advantage of variable engine speed of inverter generators is low noise levels. At low engine speeds, the noise of the generator will be very low. So, you don’t have to worry about disturbing others and use the generator even during the night times.

Small and Compact

Similar to other portable generators, inverter generators are also small devices. Due to the internal construction and usage of a lot of solid-state electronics, the size of inverter generators is even more compact.

Most inverter generators in the market come with a carry handle and/or wheels. You can easily carry or move them from one location to other or transport them in RVs or campers.

If you compare the size-to-power ratio of a traditional portable generator and an inverter generator, the former wins by a decent margin.

Parallel Operation

You bought a tiny inverter generating assuming that it is sufficient for your power requirements. Now you are running the generator at full capacity but still couldn’t fulfill the power needs.

Many inverter generator owners find themselves in a similar situation. This is where the “Parallel Operation” of the Inverter Generators comes in handy.

Most inverter generators in the market support parallel operation i.e., connect two generators in parallel and extract the combined output from them. If both the inverter generators are identical, then theoretically you can get double the power from them.

This is a very useful feature as you don’t have to purchase a new, large, and obviously expensive generator. Just buy a small inverter generator that is the same or similar to the one you already own and connect them in parallel.

You might need to purchase a Generator Parallel Kit, but the overall cost of doubling the output power is significantly less than what you would spend on a single large generator.

Other Features

Most modern portable generators are very safe devices with many safety features. Even Inverter Generators incorporate several safety measures so that there is no harm or danger to the operator, appliances or devices, or the generator itself.

One very useful safety feature is Auto Shutoff. Inverter Generators have several temperature sensors that constantly monitor the temperature of the generator unit.

If it detects an abnormally high temperature i.e., the generator starts to overheat, then the system intervenes and shuts down the generator. If the engine oil level is low, even then the generator automatically shuts down.

These safety features are on the inside. Coming to the external safety features, the output is driven through a circuit breaker so that the load cannot draw more than the rated current.

Inverter generators are available in a variety of sizes and power outputs. If you are looking for a portable generator for camping trips or tailgating, then a small inverter generator (with a power rating of 2,000 Watts) will serve you well.

But if you need a generator as an emergency backup power solution for your home or small business, then a slightly larger inverter generator (with a power rating of 3,500 to 4,000 Watts) is a better option.

Advantages of Inverter Generators

Here is a list of the main advantages of inverter generators:

• Inverter generators are small, compact, and generally lighter than traditional portable generators. You can easily move them around, carry them, or even transport them at the back of your RV.
• The ability of Inverter generators to adjust the speed of the engine speed as per the demands of the load means they are much more fuel-efficient than traditional portable generators.
• If you are worried about the noise from the generator then you don’t have to worry with Inverter generators as they produce very less noise than traditional portable generators. The low-noise operation is very useful for outdoor activities such as camping, tailgating, etc. You can use the inverter generator in a residential neighborhood without worrying about a noise complaint.
• The main selling point of an Inverter Generator is how clean its output power is. So, if you plan to run a lot of sensitive electronics such as computers, stereo, audio, etc., then it is very safe for them.
• Speaking of safety, inverter generators come with an auto shutoff feature, where the unit shuts itself down if it detects any overheating. We have circuit breakers on the output side to protect from overcurrent.
• You can use the Inverter generator in a wide range of applications. Emergency power backup system for homes small businesses, camping, recreational activities, worksites, and many more.
• Last but not least, unlike other types of portable generators, the majority of inverter generators support parallel operation. You can connect two compatible inverter generators in parallel and extract double the power from them.

Disadvantages of Inverter Generators

Here are some of the main disadvantages of inverter generators:

• The first and main disadvantage of Inverter generators is cost. When you compare the price of traditional portable generators with similar power inverter generators, then the cost of inverter generators will be very high.
• While we said the small and compact design of inverter generators is an advantage, there is a disadvantage hidden behind this. If you take a similar-sized inverter generator and a traditional portable generator, then the power rating of the inverter generator is very low.
• Due to their low power output, inverter generators are generally not recommended to run power tools and power-hungry electrical appliances.
• Inverter Generators contain both mechanical and electronic components. Their overall design is very complex when we compare it with traditional portable generators. This means it becomes very difficult for any repairs.
• Even with better fuel efficiency, smaller inverter generators have short run times. So, you have to refuel (or replace the propane tank) very frequently if you use the generator for a continuous period.

Applications of Inverter Generators

Here are some of the main applications of inverter generators:

• The main reason one buys a portable generator is to use them during emergencies. Inverter Generators are very useful devices during power outages. You can use them as backup power systems for homes, small offices and businesses, RVs, etc.
• Inverter Generators come in handy in places where there is no access to utility power. Job sites and remote work locations can use inverter generators to power different tools. But keep in mind that the power rating of inverter generators is usually less than that of traditional portable generators. So, check the power rating before plugging in any power tools.
• If you are planning a camping trip with your family, then a small inverter generator becomes essential. You can go hunting, fishing, or any other outdoor recreational activities without worrying about power.
• You can also use inverter generators to provide power at outdoor events like concerts, festivals, and family gatherings.
• While large medical facilities have automatic standby power supply, a tiny inverter generator can be useful to operate any medical devices or equipment in case of an emergency.

These are some of the main applications of inverter generators. Depending on your specific needs and requirements, an inverter generator may be an ideal solution for your portable power needs.
