Portable inverter generator buying guide

Now, you may have decided on buying the best inverter generator as a portable power source. However, which is the perfect choice for your needs? You can find inverter generators in a range of designs and models. We have guided you on how to purchase the right inverter generator.

Wattage

Wattage is one of the most important factors for buying inverter generators. The higher wattage ratings indicate the production of more power. The generators with higher wattage ratings may be costlier. Based on your purpose of using the inverter generator, you need to choose the product. 

The light-duty ones have 2000 to 3000 wattage ratings, and they are best for tailgating and camping. You may also use them for operating blenders and charging mobiles. Moreover, a 3000W inverter generator is ideal for RVs, small air conditioners, and boats.

When you have chosen the medium-duty ones, the wattage varies between 3000W and 4500W. They have the potential to operate industrial systems at the job sites. What’s more, you can buy them for your emergency home use. 

The heavy-duty ones have wattage ratings of more than 4500W. To operate all appliances of your home, you can invest in these inverter generators.

Thus, you have to identify your needs to buy an inverter generator.

Capacity

The fuel tank size is one of the important factors to purchase inverter generators. The tank can hold 1.0- 3.0 gallons of fuel. However, the best inverters are available with an Eco Mode switch that relies on the load-sensing mechanism. It adjusts the engine speed automatically to generate the power for your electrical gadgets. While connecting devices, the speed will have an increase. Thus, after the disconnection, the speed will slow down.  

Portability

The open frame inverter generators have a compact design enclosed in a case. The size can range from 2 to 3 cubic feet. The lightweight models are below 75 pounds, and you may carry it anywhere by gripping the handle. The larger units have wheels to ensure portability.

Noise level

The inverter generator works quietly to add power to your devices. Still, you have to check out the noise rating while buying portable models. Manufacturers measure the decibel from 23feet away. When the inverter generator produces more than 60dB sound, it may be slightly louder.

Additional features of the inverter generator

You can look for some other user-friendly features of the inverter generator-

  • Low-oil indicator- There is an alert system warning you about the fuel tank’s low oil level.
  • Hour meter and fuel meter- The LED display shows the hour meter, while the fuel gauge helps check the fuel level.
  • CO guard- While there is a high accumulation of CO gas around the inverter generator, the guard will shut down the system automatically. It is one of the safety features found in the best quality inverter generators.
  • Wireless remote start- You can start and stop the system from a site 300 feet away from the generator.
