frequently asked questions

What is an inverter generator?

The difference between an inverter and a standard generator is the type of electricity generated by the device. Like the standard generator, the inverter generator has an alternator. The difference is that it converts alternating current (AC) power to direct current (DC) power through a device, and then converts it back to alternating current through an inverter.

Is a dual fuel inverter generator worth it?

Power outages: When power outages occur due to natural emergencies or disasters, gasoline supplies are affected. People living in harsh climates know the value of having natural gas backed up at home. However, during a power outage, stored gasoline may spoil or be consumed rapidly. Having a second fuel option can give you more peace of mind. The stored propane keeps your generator running when the gas runs out, and the beauty of propane is that it has a very long shelf life (over eight years).

Construction sites: Many construction sites do not have grid power. On a job site like this, a generator can power your tools, especially when the main power source is interrupted. A dual-fuel generator goes even further, allowing you to run the machine on gasoline and propane. Remember that dual fuel inverters can only run tools with power requirements lower than the output power of the inverter.

FUN AND ENTERTAINMENT: Dual fuel inverters are also a great choice for fun activities such as RVs, camping, tailgating and beach parties. Running a dual fuel inverter on propane is a practical option for this type of activity. Not only does propane produce less noise, but its exhaust is also less harmful than gasoline.

Can an inverter generator run a refrigerator?

Most inverter generators have no problem running modern refrigerators, which only require up to 1,000 watts at startup. If you're looking to power the refrigerator in your RV or home, you'll want to look at at least the mid-range range (2,000 to 4,500 watts).

What is the difference between a generator and an inverter generator?

The main difference between these two types of generators is how they operate. When you run it, the inverter adjusts its power level to the equipment it's powering, so it's more efficient. With inverters, there's also less technical maintenance required - unlike traditional generators, they don't No special handling is required for standard maintenance. They can be more easily paired with other units for parallel functionality without the need for new transfer switch connections. They are generally quieter, lighter and more portable than your standard generator options.

This is not the case with conventional generators. They require a certain speed to provide power (usually 3,000 RPM) and maintain a steady current flow. After getting power from your favorite fuel (the most commonly used power source), the motor works with the alternator to produce a steady power output.

You will notice this if the engine speed of your conventional generator changes. Such fluctuations will cause fluctuations in the electrical output frequency.

Another major difference is portability. Inverter generators are smaller, lighter, and may even have wheels, making them easier to carry around. This is why portable inverter generators are so popular among campers.

What is a parallel connection?

Parallel connections allow you to connect two inverters of the same model and double the power output and sockets. This feature comes in handy when you have to run heavy machines that a single inverter can't manage. For example, you need to run a sound system at a 3000 watt outdoor party and you have a 2000 watt inverter. If a friend of yours also happens to have a 2000 watt inverter (same model), you can connect two units in parallel and get a 4000 watt output. This way you can run your speaker system and still have some power to run some other equipment.

How does an inverter generator work?

An inverter generator does not have a separate engine and generator; it combines the two parts into one machine, making it lighter and more compact. Inverters work by taking alternating current, breaking it down into direct current, and then rebuilding it into a controlled, stable, and high-quality alternating current.

In recent years, the appearance of inverter generators has made people more convenient and fast in terms of electricity demand. Many generator wholesale factories in China have also begun to promote the technology of inverter generators to the world.

If you are thinking about trying now, want to import Chinese inverter generator, or you have searched the internet for a long time but have not found a suitable inverter generator factory, you have come to the right place. The information below will assist in selecting the best unit, we have super quiet inverter generator, dual fuel inverter generator and various power inverter generator.

What is an inverter generator?

Simply put, the inverter generator converts the energy produced by fossil fuel-gasoline into electrical energy.

The ordinary generator has two main parts-the engine and the alternator. The engine consumes fuel, such as gasoline or propane, and turns the shaft. The alternator has two main components-the rotor and the stator. The engine shaft turns the rotor, thereby generating power in the stator. The power supply enters the control panel and is used to power any equipment you need-power tools, electrical appliances, etc.

However, the inverter generator does not have a separate engine and alternator; it combines these two parts into one machine, making it lighter and more compact. The working principle of the inverter is to obtain AC power, decompose it into DC power, and then rebuild it into a controlled, stable and high-quality AC power.

How does an inverter generator work?

The inverter generator generates electricity in a "pure sine wave" format (ie continuous smooth wave). Traditional generator technology provides power in the form of a chopped square wave.

The alternating current (AC) generated by the alternator is sent to the rectifier, which is a device that converts the alternating current into direct current (DC). Then, before sending the DC power to the control panel, the computer in the generator converts the DC power back to AC power. This is where the name "inverter" comes from.

The main advantages of inverter generators over traditional generators:

1. Pure sine wave

Inverter generators provide clean, pure power output, while conventional model generators have surges and spikes that can damage appliances and are not conducive to stable current output.

inverter generators provide clean and pure power output

The inverter generator can protect your Gadgets, such as mobile phones, laptops, etc., to prevent the product from overheating and overloading during charging. The traditional portable generator provides a higher output than the frequency converter, and transmits the generated electricity directly to the control panel through a voltage stabilizer or other protection device, but not necessarily a "clean up" the power source. However, the result of inverter technology is cleaner power delivery, which can be adjusted up and down according to the load to minimize total harmonic distortion (THD), this makes variable frequency generators very suitable for sensitive equipment.

In addition to being very suitable for charging your laptop or mobile phone, the inverter generator also be suitable for your household electricity. Because of its quietness, it will not disturb your neighbors or your travel.

2. Perfect portability

When users pack for a big weekend camping trip, lugging a bulky gasoline generator to the back of a van is a pain. This is no longer the case with BISON inverter generators, most of them are average sized and weigh around 50 to 80 pounds, which anyone can lift. They are smaller and lighter than ordinary generators, this means that it can be easily moved to where power is needed. In addition, fishing trips, outdoor adventures, and any other types of activities that require portable, reliable, stable and quiet power sources.

3. Very quiet

One of the main advantages of inverter generators is low noise, making them ideal for applications with decibel limits, such as farmers markets and campgrounds. Sound attenuation engineering makes BISON inverter generators ideal for neighborhood block parties, food trucks and sensitive building environments.

4. Better fuel efficiency

Compared with other generators, variable frequency generators have better fuel efficiency, allowing the engine to utilize fuel during peak periods and provide smooth service for long periods of time.

5. Parallel operation

This is difficult to do with many gasoline generators, users can connect two BISON inverter generators together with a parallel kit to increase the amount of power needed.

6. Green living

Compared to conventional generators, it produces less carbon emissions and is more fuel efficient, so it can meet local environmental quality requirements. 

Disadvantages of inverter generator

1. expensive

Due to the advanced technology, the cost of these inverters is higher than that of traditional equipment. While inverter generators are expensive, but they run longer, are quieter, and are more efficient.

2. low output

Although they provide steady power, they are not as powerful as traditional generators. If you need more power, you can connect two units.

Inverter generators are a very reliable source of energy that can meet the needs of various electrical equipment powered by generators.

different inverter generator types

When you are in the market for an inverter generator, you will find that there are many different types of generators to choose from. If you are confused, you can follow BISON to learn about the different types of inverter generators that can be adapted to various applications.

Below are the main inverter generator types

Explore inverter generator to match your project!

inverter generator types by usage scenarios

Inverter generator for work

Inverter generators with a maximum output of more than 5,000 watts are recommended on the job site.

It can run power tools and can be connected directly to the electrical panel. These generators are equipped with a safety transfer switch.

Since it is the heaviest and largest type of inverter generator, they have built-in wheels for easy transport around the job site.

household inverter generator

A medium-sized inverter generator with a maximum output of 3,500 watts is ideal for home backup power.

Can run basic household appliances: electric stove, air conditioner, cooler, radio and TV.

Safe to use on sensitive devices like laptops and mobile phones.

Inverter generator for outdoor use

BISON inverter generator with a maximum output of 2,000 watts is more than enough for camping and outdoor recreation.

2200 watt inverter generator can power campsite lights for safety, power portable electric stoves and charge mobile devices.

Very quiet and will not disturb nearby campers. Portable and can be easily put into the car. 

inverter generator types by fuel type

If we differentiate according to fuel type, inverter generators are simply divided into three types. The most common uses gasoline as the fuel, however, there are some options on the market that use propane or natural gas.

Choosing a inverter generator

The above are the main types of inverter generators, to make the best investment when working with inverter generator suppliers, please also consider the following factors:

power output

Do you want to sell to people who take their generator with them on the go, or as a backup generator in case of a power outage? Once you've determined what you're going to buy your generator for, you can determine how many watts you'll need. So you can choose the appropriate power according to the guide:

  • Light duty (tent camping, tailgating, etc.): 1,000 to 3,000 watts

  • Medium (RV camping, emergency home use, work site, etc.): 3,000 to 4,500 watts

  • Heavy Duty (powers the entire home, powers the welder, etc.): 4,500+ watts

If you're only using it to power a radio or a small refrigerator, a compact portable generator might be the way to go. If you want to keep things like your RV air conditioner running, you need a medium-sized inverter generator with slightly more power than a small generator.

dimensions and weight

Some shoppers will consider their physical size and weight. As the name suggests, hand-held inverter generators can be picked up with one hand and carried easily, as they are typically lightweight, around 40 to 50 pounds. The downside is that these units typically have a power output of 2,200 watts and below.

Wheeled units provide more power (3,000+ watts), but they are big and heavy. So it might be easier to use one of these units as a home generator. BISON's wheel kits are also sold separately so you can add them to your existing generator, or replace your old wheel kits, having a wheel kit will make transporting heavy duty inverter generators easier.

fuel type

Inverter generators typically use gasoline as the fuel source, and dual-fuel inverter generators can also run on propane. This is a great advantage as it will help you sell better, such as meeting power output requirements, local fuel availability and the type of fuel on hand.

fuel tank capacity

Inverter generators have a separate fuel tank with fuel capacity ranging from as little as 2 gallons to over 10 gallons. The larger the tank on the generator, the longer the power will last, but the size of the generator itself will also increase. For dual fuel inverter generators, since the propane gas is stored in the tank, which is connected to the generator by a hose, there is basically no significant change in the size of the generator.

starting method

The inverter generator has two ignition methods: electric start switch and recoil start:

  • Electric Start: Generators with electric start store extra power in an internal battery that automatically starts the device. Users can simply press a button. This way of starting is much easier than starting with recoil. But if the internal battery is dead, you won't be able to use electric start.

  • Recoil start: Recoil start is an old but reliable technique. This method of starting requires you to pull the recoil line quickly and steadily to start the engine. Although the generator may be pulled more than a few times when using the generator, however, there will be no situation where the electric start variable frequency generator cannot be started due to insufficient battery power due to too long storage time.

    recoill start inverter generator

  • Remote start: Portable inverter generator with wireless remote start includes a handy remote key to ensure quick and easy access to the inverter generator.

load sharing

Most of what BISON offers are inverter generators that support parallel use, also known as load sharing. Using BISON's connection kit, users can safely combine the power of two generators. Also, having two generators prevents one of them from failing and not being able to generate electricity.

noise level

The most notable difference between inverters and open generators is the amount of noise they produce. Open generators produce decibel levels well over 100 dB. Inverter generators are about half as noisy as open-frame models, typically in the 50 to 60 dB range. Inverter generators also use sensors to detect how much power they need to consume, throttling smaller loads and producing lower noise levels.

Refrigerator50 decibels
Normal voice60 decibels
Vacuum cleaner70 decibels
Hair dryer70 to 90 decibels
Motorcycle95 to 110 decibels


Last but not least, make sure the inverter generator is within your budget. Although you are free to choose some additional features offered by BISON, wholesale a few machines that will not exceed your budget is the most important consideration.
