Frequently Asked Questions

 

1. What is an inverter generator?

If you're looking to buy a portable generator, you might want to consider an inverter generator as new models with CO safety shut-off start to appear online and on vendor store shelves. Basically, inverter generators are more expensive than conventional portable generators, but they have distinct advantages.

Inverter generators electronically adjust the motor up and down to meet demand rather than always running at full tilt. The improved performance means you won't have to refill the gas tank as often. Inverter generators are generally very quiet. They also produce lower emissions.

 

2. Which is better? Inverter generator vs generator for regular use?

Conventional generators only generate AC power while inverter generators generate electricity in 3 phases (high-frequency alternating current into DC back to steady alternating current). The stable sine wave is what makes an inverter generator unique. It is considered clean power.

When comparing regular generator vs inverter generator, we easily notice a few obvious differences as follows:

  • The conventional generator will produce more power than the inverter generator. However, it won't save you fuel.

  • If you want to carry the generator everywhere, then the inverter generator will be a perfect choice. It is neat and easy to move.

  • Certainly, inverter generators will be quieter than conventional due to their capacity. 

3. How big an inverter generator do I need?

You can run your most important home appliances with generators ranging from 5,000 to 7,500 watts. These include things like good pumps, refrigerators and freezers, and lighting circuits. 

A generator with about 7500 watts running can run all of these devices at the same time. For RVs, a 3000 - 4000 watt generator would be ideal.

4. Is an inverter generator worth it?

The best inverter generator is more energy-efficient thanks to the way the final alternating current is generated. The motor of an inverter generator automatically adjusts to the load that a conventional portable generator cannot do. For smaller fuel tanks, inverter generators allow for greater fuel efficiency.

5. Why are inverter generators so quiet?

The main reason an inverter generator is so quiet is because of the technology it uses to produce clean electricity. Inverter generator motors are also generally smaller with lower output power, which is another noise reduction factor.


Final Words

Inverter generators are the perfect choice for camping trips or outdoor activities. We firmly believe that the best inverter generators will not let you down. Please tell us your choice and recommendation if you have any!
