inverter generator wholesale guide

China BISON is a professional inverter generator factory&supplier. Wholesale 2021 best inverter generator at the competitive price. Before purchasing a variable frequency generator wholesale, the following factors must be considered:


Inverter generators have a wide power range. According to your usage scenario, you can choose the appropriate generator wattage. The correct wattage will meet the needs of a specific population, ensure adequate power supply, and you can sell better.

  • If the application is camping or in an RV and needs to be moved around a lot, it may be beneficial to find a portable inverter generator that is easy to handle, although this type of inverter generator tends to have a small power output. Also, you need to pay attention to the weight of the generator and whether it has handles or wheels or something.
  • If you need a lot of electricity to support important machines and appliances in your home. Most large inverter generators have a maximum power of 7,000 watts and can cover critical equipment until power is restored. If you want more than that, then you may want to opt for a traditional generator.

noise level

Inverter generators are known for being quieter than traditional generators. The inverter generator produces 58 decibels to 62 decibels of sound at full rated output. Due to the compact design, the inverter uses a smaller motor, which reduces noise levels. Another noise reduction feature is the ability to operate at different output levels. BISON inverter generators are loudest at full load, but not all jobs require that much power. A quieter experience when maintained at the output level of a smaller job. In addition, the body shell also takes most of the credit for reducing the sound. The inverter is made of insulating sound-dampening material that absorbs the noise generated by the generator, making it an ideal power source for camping or residential areas.


It is worth noting that inverter generators generally consume less fuel than other types of generators. So you can use them for a long time without having to refill the tank as often. You can choose between gasoline, diesel and propane depending on your needs. Gasoline is the cheapest and most flammable type of fuel. For this reason, it cannot be used in enclosed spaces or areas with fire hazards. Propane, on the other hand, is not flammable, which means it can be used in any environment without worrying about anything. Diesel is very clean and can be used safely in any environment. Generator capacity is measured in gallons per hour (GPH). This means that if your generator has a GPH capacity of 1 gallon, it will be able to run for an hour before running out of fuel.

Stable power

First and foremost, inverter generators provide the most stable power output of any generator, thanks to its inverter technology. Unlike conventional generators, the inverter generates more than 300 sine waves per revolution of the engine. This three-phase alternating current is converted to direct current and then converted back to 120 volts/60 hertz alternating current (or other volts and hertz). This means you get consistent, regulated "clean" power without surges. So you can power even the most sensitive electronic devices such as computers, TVs and other devices with microprocessors.


Ensure that the inverter has safety functions such as surge voltage protection, low oil shutdown, and overload protection. In addition to these features, GFCIs and covered sockets allow users to use the machine safely.

Precautions to be considered when using generators:

  • Children are forbidden to operate.

  • Pay attention to electricity safety.

  • Avoid using it indoors or in enclosed spaces. Remember, every internal combustion engine produces carbon monoxide.

  • Dispose of fuel safely.

Inverter generators are suitable for demanding precision electronic instruments, computers, lamps, UPS, LEDs and other equipment. In addition, large-scale RVs, engineering vehicles, TV OB trucks and other outdoor operation vehicles are inseparable from inverter generators. Consider buying a technologically advanced generator?
