          How Does an Inverter Generator Work?

          The mechanics of inverter generators are slightly more complicated than conventional portable generators. There are more parts involved in delivering the final electrical output.

          Many inverter generators also run on fossil fuels. In addition to the drawing power from the fuel tank, inverter generators also have a battery, alternator and inverter.

          The power from the engine is a high frequency AC current which is then converted into DC current by the alternator. That DC current is then converter back into AC current by the inverter.

          Like with conventional portable generators, inverter generators also have an output of 120 volts at 60 Hertz. However, because of the extra steps in the electricity production, the current of an inverter generator is much more stable.

          In other words, there is less harmonic distortion which is why inverter generators are said to produce ‘clean electricity’. The quality of electricity produced by inverter generators is comparable to the quality of electricity that you receive from the mains electrical supplier.

          The clean electricity is possible because of two factors. The first factor is that the initial AC current in an inverter generator is at a high frequency which gives more electrical energy.

          The second factor is the inversion of the DC current back into AC current. The mechanics of an inverter generator has more control over the AC frequency which lets it provide a very stable sine wave.

          The greater control over the electrical output makes inverter generators quite energy-efficient. It can adjust its voltage to what is exactly needed by the connected load while still maintaining an rpm of 3600.

          The stable current is also one of the main reasons why inverter generators are quite silent compared to conventional portable generators.


          Benefits of  Propane inverter Generators

          The advantages of inverter generators over conventional portable generators is that they are more quiet, are more compact and lightweight, more fuel efficient, are safe for sensitive electrical devices and are generally more environmentally friendly.

          Here are a few benefits of having a propane inverter generator compared to gasoline and diesel generators.


          1) Propane is easier to access during natural disasters

          Gasoline pumps need electricity to function, so if you are caught in a long-term power outage you may have trouble restocking your gasoline supply.

          This means that when using a gas-powered generator, you generally need to stock up on fuel in advance and store it somewhere at home.

          With a propane-powered generator you can relax knowing that you can still purchase fuel if you run out. It doesn’t require electricity to fill a tank of propane.

          Propane is also safer to store. Except in the coldest of environments, propane works well. If you are in an area where the temperature is below zero °F then gasoline might be a better option for you.

          For us, storing gas is an issue because we are so prone to wildfires and gas is highly flammable.

          For those reasons, if the main purpose of your generator is to be a power source during an emergency, then you should consider a portable propane generator or a dual-fuel generator that can run on propane.


          2) Propane generators can require less maintenance

          There are certain kinds of maintenance that you’ll have to conduct for gasoline and diesel generators that you won’t have to do for one that runs on propane.

          Gasoline and diesel leave carbon deposits in your engine and exhaust, which need to be cleaned from time to time. These fuels also leave residue in fuel lines and system parts, adding additional maintenance.

          Propane has none of these effects upon engines, making propane generators easier to maintain. Some of the best portable propane generators won’t require any fuel maintenance, other than ensuring your tank is adequately full.


          3) Propane has a longer shelf life

          You can only store gas for about 12 months, but you can store propane indefinitely. It will literally outlast the container holding it. So the only long-term concern is maintaining the tank. This allows you to stock up on it without worrying that it’s going to degrade and be useless when you need it.


          4) Propane is safer

          Propane is a “cleaning burning” fuel, which means that it produces a significantly lower amount of carbon monoxide and doesn’t act as a greenhouse gas like other fuel sources, specially gasoline.

          Releasing around 30 percent of the CO of a typical gas-powered generator, many people consider propane to be the best generator fuel around.

          While you still need to respect all rules and guidelines for ventilation, creating fewer emissions is a major advantage when you’re considering gas vs. propane generators.

          Also, propane is a better option as a power source because it is non-toxic and is released as a gas.

          So, when your tank is being filled there is no risk of spillage, especially with the hassle-free and safe hose and valve attachment that is used when connecting your propane tank to the propane source (a larger safe tank) during fill-ups.

          Gasoline is a different story. There is a risk of spillage and hassle associated with filling a gasoline tank, which doesn’t protect our environment at all.

          Propane’s high ignition point, 940 degrees Fahrenheit, makes it less of a fire hazard than gasoline, which ignites at 430 to 500 degrees Fahrenheit.


          5) You can run a propane generator 24/7 without even touching it

          Most gas-powered generators come with a predetermined tank size and depending on the efficiency of the unit, must be monitored often so as not to run out of fuel.

          With portable propane generators, you determine the tank size and those can range from 5-gallons to 1000 plus gallon tanks. This means that you can use the generator as needed without management.

          The best propane generators can operate for roughly eight to fifteen days when fully stocked with fuel.

          They often have smart features that shut them down if there is a problem with fuel delivery or if there is a systemic issue. You might not even notice your propane generator is running if you put it far from your house.


          Final verdict

          Your generator will become your best friend when you find you need it most. Whether it’s an emergency power outage during a large storm or a convenient luxury during a camping trip, the additional power can always go to good use.

          If you’re new to the world of electrical generators, don’t worry. We have listed a few great propane compatible systems that have only the highest ratings and quality materials. We have also equipped you with lots of information to help you along in your buying process.

          While there’s nothing wrong with using gas, propane does have many advantages that you may want to consider. It’s cheaper, it has a much longer shelf life, and it’s readily available during power outages.

          Think about the information we’ve given you to make the best buying decision for Best propane inverter generator.
