Best Dual Fuel Inverter Generator[2020]

Best Dual Fuel Inverter Generator [2020] – Buyer’s Guide & Review 👈

A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC).

The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.

A Best Dual Fuel Inverter Generator can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process.

Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.

 To understand the portable inverter generator and how it compares to the common portable generator, we’ll first look at inverter technology in its simplest form.

You might be familiar with a common 12 volt battery inverter which is an electrical device that converts 12-volt DC power into 120-volt AC power.

Typically you run this type of inverter off of your car’s battery or off of a deep-cycle battery that you buy specifically to power the inverter.  Although fairly inexpensive, the shortcoming is that typically an inverter is a useful solution if you can keep your power demands in the 200-watt range.

You could get one with a more useful 2,500 watts, but it will cost close to $1000 and that’s not including the bank of deep-cycle batteries and a charging system.  For more demand than that, you should consider a fuel powered inverter generator. Unless the “clean” AC power that an inverter provides is important to you.

Consider a car’s battery has a reserve capacity rating.  A typical rating is 80 minutes, which means the battery can supply 25 amps at 12 volts for 80 minutes.  Without going into the math, if you draw 120 watts continuously, at 10amps, this might last three hours, possibly eight hours on a deep-cycle marine type battery.  But then you have to recharge the battery.

The reason I mention that is, some will opt for a portable generator for most of the daytime duties of a power outage, then run a couple of lights at night off of an inverter.  You can run a couple of 15 watt bulbs (2.5 amps) for about 12 hours on a car battery.

In addition, your car’s alternator can generally only supply 700 watts.  So to run more than a 300watt inverter from a car, you’ll need to connect it directly to the car’s battery with cables, and then you will need to run the car’s engine continuously.  So that’s where a gas powered portable generator makes sense.

So why not use the inverter to power anything it can? Then when the batteries are depleted, or you need large loads to turn on, run a standard generator for a long time (at least an hour) to power the heavier loads.  Meanwhile let the battery charger then re-charge the battery to give the inverter its efficient power once you’re ready to shut the generator down. This one-two punch allows the most efficient use of fuel (only using a pollutant when you’re getting the most effectiveness out of your fuel).  You’ll run the noisier generator less,  and equally important, you’ll save money since you’ll use less fuel for the same used kilowatt hours.

Best Dual Fuel Inverter Generator may take some math and some planning, but you can partner a good inverter with a small generator and reap the benefits of a light-weight, highly efficient, usable system.

What is the best dual fuel  Inverter Generator?

Best Dual Fuel Inverter Generators have some real advantages over conventional generators. First and foremost, they’re quiet.  Standard portable generators are infamous for the noise during operation.  Offending neighbors or fellow outdoor enthusiasts is always a concern.

In addition, these new units are a lot lighter and smaller: 1,000-watt inverter generators weigh about 30 pounds and are about the size of a small cooler.

Best Dual Fuel Inverter Generators are also about 20 percent more fuel efficient than regular generators. A typical 2,000-watt unit can run at its rated load for nearly four hours on a gallon of fuel.

And finally, as previously mentioned, inverter generators produce electricity that’s somewhat safer for sensitive electronic equipment, such as laptops.

You will however, pay more per available kilowatt in a portable inverter generator.  That is, a 2Kw inverter will cost you much more than a 2Kw standard generator. This hasn’t stopped consumers from making these nearly a must-have household appliance.  The portable 1000 watt inverter generator is becoming commonplace for those who see the value of portable power and understand the limitations of powering one device at a time.

 

Typical Uses of Best Dual Fuel Inverter Generators

From the outset,best dual fuel inverter generators were marketed to the thousands of campers, hunters and fishermen who wanted to bring the comforts of home into the great outdoors, while being less cumbersome and quieter.

Think of the great outdoors.  You’re “roughing it” under the stars.  But for necessity, convenience and safety you have your cell phone with you, right?  The inverter generator will safely keep your phone charged.

They are popular in the construction industry because workers can power up at 7 a.m. or in a quiet zone without the rumble of a standard  portable generator.  Best Dual Fuel Inverter Generators produce about the same level of noise as a normal conversation (50 to 60 dBA) — that’s quieter than a household vacuum cleaner. Conventional generators can be as noisy as 65 to 75 dBA (decibels), about as loud as a lawn mower or chain saw.

 Features to Consider:-

Small differences in the design of various inverter generators can make a big difference in how easy they are to use and maintain, but also affect price.  Keep these factors in mind:

  • Control panels on better units include a display that allows you to monitor voltage output, frequency (Hz) and hours of operation. They also include LEDs that warn of over-load conditions.
  •  Many units include controls that allow you to switch from automatic power saving to a power-boost mode when short surges of power are required.
  • Weight and size depend largely upon watt output.  Depending on weight you may opt for some sort of wheel transport apparatus.
  • Noise levels can vary from manufacturer to manufacturer, even for units with the same output. When evaluating noise, be sure you’re comparing apples to apples — especially in regard to how far the unit was placed from the sound-level meter and the load at which it was running.
  • Some units include a battery-charging cable, a spark plug wrench and a generator cover. Units that are designed to connect with best dual fuel inverter generator (for twice the power) come with parallel cables.

 

 What To Consider When Buying a Best  Dual Fuel Inverter Generator?

During outages, you want the best machine to power your home or job-site. Understanding why this is an important feature for many homes, we have some points for you to consider to make a more informed decision. Based on affordability and capability, you can make a choice on which is the best dual fuel generator for your needs.

Budget

Working with a budget you can afford is of paramount importance in any purchase, especially with essential home equipment like a generator. If you have a budget, it is easy to make a choice on a range of generators you can afford. The cost of a best dual fuel inverter generator ranges from several hundred dollars to several thousand. Higher power generators will command higher rates. Undoubtedly, a good price will most often than not come with better quality too.

Fuel Storage & Temperatures

An important factor to consider when purchasing a portable best  dual fuel inverter generator is fuel storage and temperatures. Often, gasoline is the popular choice because it is affordable. The downside to gas is that it does not last long due to its short shelf life as heat makes it evaporate. In this case, propane is a good choice as it lasts indefinitely.

 However, the only downside to propane is that cooler temperatures under 40-degrees Fahrenheit make it contract causing a drop of pressure in your propane tank. Because of the drop in pressure, it may not be enough to start up your generator while it is on propane alone.

Also, consider your fuel storage and the ideal temperatures for your choice of fuels. The best part about best dual fuel inverter generators is that you have the choice of any of the fuels so you will never be let down during an emergency. However, these are just some factors to consider when purchasing a dual fuel generator, so you are best prepared with both fuel choices and use them optimally without wastage.

Power & Size

Size is an important factor when choosing a best dual fuel inverter generator. Most of the good models are large, but that does not mean that you cannot get a small machine with great features at an affordable price. Consider the total wattage, weight, and portability when purchasing a dual fuel generator. That said, better models are larger in size and sometimes come at a better cost too.

 

Neighborhood Friendly

If you love your peace and quiet time, you may want to pay attention to the noise level of your generator. When using a generator around people or a residential area, noise can be a huge deal. Nobody wants to wake up in the middle of the night because of a large and annoying generator. The quietest best dual fuel inverter generator models should emit noise less than 65dB. Check that the noise level is acceptable to you before making a purchase. Some good models stay below 50dB.

Find Out Your Location Limitation

There are location limitations if you live in an area where running or fueling your generator will be troublesome. Cases of these include snow during winter that will prevent you from running your appliance outside. The distance to the nearest gas station may be far, requiring you to have a reserve for fuel. Calamity-prone areas will also require you to be ready at all times in case a disaster cuts your supply options.

Safety Consideration

Flammability should be your main concern. When running best dual fuel inverter generators or any generators in general, remember to consider the flammability of your fuel. Gasoline vapors are typically highly flammable. Diesel is less volatile as it is oilier and heavier, thus evaporating slower than gasoline. While diesel has a boiling point that is higher than water, gasoline vapors are emitted at room temperature. In both cases, you still run the risk of spills. Always take your safety considerations first.

Advantages Of Best Dual Fuel Inverter Generator

While any generator will benefit your home, a best  dual fuel inverter generator doubles this by giving you a viable option to either use gas or propane. Gas fuel generators have their benefits; for example, they are easily accessible. However, they also have their disadvantages. As a result, a dual fuel generator allows you to use propane instead. Propane is cleaner, quieter, and cheaper.

Versatility

It is great to have options in case one of the resources is not available. Let’s say there is a power outage in your area, and you have no gasoline ready for your gas-powered generator; you might be out of luck if all the local stations have none either.

What if you live in an area that is prone to hurricanes and blizzards? Such a natural disaster can leave you without power for days. With a reliable best  dual fuel inverter generator, you have the option of using the type of fuel that is available to you. When one runs out, you simply switch to the other, and you have power for days.

Effectiveness

There is a common misconception that a dual fuel generator has a reduced efficiency and quality for the amount of power you have from running either of your fuels. The truth is that they are just as functional, if not better. Whether you need the power to run small power tools or larger appliances, the best dual fuel inverter generator will get the job done for just as good as a single fuel generator. Since there is a range of options to choose from, you can get a generator that is best suited for your needs.

Further, best dual fuel inverter generators are more efficient than single fuel generators. In case of an outage or natural disaster, you can rely on your bi-fuel generator to provide power using the fuel available to you at the time. They function great even in cold areas and tough weather conditions so you can depend on your generator for power during tough times.

Economical & Easy Maintenance

Best Dual Fuel Inverter Generators are easy to maintain as you can easily move them for repairs in case of a breakdown. Unlike whole house generators that are more on the expensive side when it comes to site maintenance, repairs, and also require installation.

Durability

One of the noticeable features of bi-fuel generators is that they are designed using sturdy materials to last long. Manufacturers understand that these generators are often used in areas that are prone to hurricanes, blizzards, and tough weather conditions. As such, they make best dual fuel inverter generators with sturdy frames and strong materials for durability.

Uninterrupted Power Supply

Most of the appliances we use are powered by electricity. It is critical that there are no interruptions to your power supply. With a bi-fuel generator, you are ensured of continuous power supply all the time. This is important for all the appliances that need to stay up and running and do not have their own uninterrupted power supply. Hospitals, factories, and some types of businesses would largely benefit from a dependable best dual fuel inverter generator.

Convenience

Best Dual Fuel Inverter Generators are highly convenient because when you may not easily get natural gas and propane in remote areas, you will get diesel and gasoline in every exit and even the smallest of towns. This allows you to use the fuel you can find giving you back up, even when you run out of your preferred fuel.

Disadvantages Of Dual Fuel Generator

The main challenge you will face with a best dual fuel inverter generator is that one large unit will be more expensive than the same-size generator using only one fuel. You will have to budget accordingly and search for the best dual fuel generator to handle your needs perfectly at an affordable price.

FAQs

What size of generator do I require?

All electrical products have a data plate with information regarding their power usage. For most power tools drills, sanders etc), their listed wattage is all the power they require to run. Household items such as central heating pumps, lights, TV’s, video recorders etc. fall in the same category. Items such as freezers, fridges, washing machines, some lawn mowers are normally different, whilst they can state a wattage rating, due to the type of motor they use can require a much greater requirement on start up, when started they then require a smaller usage.

If you are unsure as to what power usage a product has it is always advisable to contact the relevant manufacturers sales or technical dept, quoting model number and requesting the START UP wattage & RUNNING wattage of your item. With this information you will be able to determine accurately the size of generator you require.

 

Do I require a generator that has a long run fuel tank?

Generators are available in either standard run or long run versions. A standard tank will last for 2-4 hrs, where most long run generators can run through the night. If you are looking to purchase a generator for back up (when you experience a powercut) then we would recommend a long run tank machine.

 

Do I want to run a computer off my generator?

Running home computers from a standard generator is not advisable. You will need a generator that utilises AVR (Automatic Voltage Regulation) such as the Briggs Pro Max 6000A or an Inverter generator such as the Honda EU & EM Range. These generators will give you more stable electricity than the mains. Please note: As a generator runs out of fuel, the engine is likely to surge. To avoid this affecting electronic equipment an Uninterruptible Power Supply (UPS) can be used. These are typically sold for use with computers so that data is not lost in the event of a power cut.

 

I have bought a generator, and I am concerned about safety. Can I use a personal power breaker?

The generator is configured differently to the mains supply. The generator has a ‘floating earth’, whilst the mains has an earthed neutral. Whereas it is definitely recommended to use a personal power breaker (RCD) from the mains, for the majority of cases, it is not necessary to use one with a generator. Personal power breakers are designed to operate from the mains. If one is to be used with a generator, then it is necessary to modify the generator so that it is configured in the same way as the mains. This is a relatively simple modification for a qualified electrician involving adding a link wire from the neutral terminal to the earth terminal. However, once the generator has been modified, it is necessary to then always use a personal power breaker and to also always use an earth spike, which connects between the generator frame and the ground. Since this is difficult to ensure, it is generally recommended not to modify the generator.

 

I have bought a generator, and would like to connect it to my house in case of mains failure. What do I need to do?

When using a generator as an alternative supply to the mains, there are several precautions that must be observed. It is vital that the generator is completely isolated from the mains supply. This ensures that the generator is not attempting to power up the whole neighborhood, but also ensures that it does not electrocute a utility worker trying to restore the mains supply.

To achieve this, a double-pole, break-before-make, changeover switch must be installed by a qualified electrician.

This should be fitted between the electricity meter and the building consumer unit. The switch connects the building to either the mains supply or to a lead which can be plugged into the generator.

Most buildings now have an RCD built into the consumer unit. This is configured to operate from the mains supply with an earthed neutral, and not from a generator with a floating earth. To utilize this protection device, it is necessary to modify the generator so that it is configured in the same way as the mains supply. This is a simple modification for a qualified electrician, involving adding a link wire from the neutral terminal to the earth terminal. It is recommended to make this connection in the plug that is to be used to connect to the generator. This ensures that the generator is unmodified when it is disconnected from the house, and therefore remains safe.

The plug should be labeled “Do not connect to mains: Neutral-Earth link fitted”. The lead between the generator and the transfer switch is not protected by the RCD, it is therefore recommended to use a steel armored cable for this connection. Finally a local low-impedance earth spike needs to be installed.
