FAQ

Are dual fuel inverter generators worth it?

Given all the benefits of a dual fuel inverter generator, we can say that it is worth buying one.
In the event of a power outage, it gives you access to a stable and reliable power source.

But now you might be wondering: doesn’t a regular alternator offer the same benefits as a dual inverter alternator?
Well, here are the features of the dual inverter generator that make it a wise and well-deserved purchase.

Unlike a standard alternator, a dual fuel inverter alternator has the following advantages:

– It has a smaller size so that it will take up less storage space.
– It is lighter in weight, so it is easier to transport from one place to another.
– It produces a lower noise level.

An ordinary alternator can produce electricity, but not without power fluctuations.
A dual inverter generator can take DC power and convert it to high-frequency AC power.

A dual inverter alternator can eliminate power fluctuations by performing this process.
Another advantage of a dual inverter alternator over a standard generator is adjusting the operating speed as needed.

A standard alternator will run steadily at the same speed level.
Although this is considered a reliable feature, the inability to adjust the operating speed also comes with its disadvantages:

– the production of an excessively high noise level
– the consumption of a large amount of combustible
An inverter alternator can adjust its operating speed according to the requirements to which it is subjected.

This feature gives the dual fuel inverter alternator the following benefits:
– producing a lower noise level
– consuming less combustible

Who makes the most reliable dual fuel generator?

If you are looking for a company that produces a reliable dual fuel generator, Westinghouse is the perfect choice for you.
The name Westinghouse is a well-known name in producing dual alternators.

This excellent company produces alternators that have very high operating power.
Also, the alternators produced by this company have a very long running time.

This fact is due to the large capacity of the tank installed in these generators.
Most dual fuel alternators also have a very long warranty period.

Which dual fuel generator is best?

If you want to buy the best dual fuel alternator on the market, you need to buy the Westinghouse WGen9500DF generator.

This alternator has several features that place it at the top of the best alternators on the market.
One of these features is the engine installed inside the alternator.

This engine is a 457CC 4-stroke engine.
Thanks to this engine with an impressive capacity, the generator can provide a running power of 9500 W when powered by gasoline.

And the maximum power it offers while running on gasoline can reach 12500 W.
The performance of this alternator remains almost the same when powered by propane.

The generator can deliver a running power of 8500 W during the propane engine supply.
And the maximum power level offered when running on the same type of combustible can reach a value of 11200 W.

This dual alternator also has a large filling tank installed inside it.
You can put up to 6.6 gallons of combustible in it.
The generator can deliver 12 hours of non-stop operation with just one entire tank supply.

This long period of operation makes this alternator the ideal solution for any outdoor tent party.
The company that makes this dual fuel generator also offers a 3-year warranty.

How do dual fuel portable generators work?

Most portable dual generators manufactured today come with a switch included in their structure.

It is possible to switch from one type of combustible to another within the alternator with this switch.
Although a generator can come with this option included, it does not mean that you have to use it.

You can use only one fuel type to power a portable dual alternator.
If you use a specific type of combustible to power your portable dual generator and it runs out, don’t worry.

You can quickly use the switch and switch the generator supply to the other type of fuel.
You can do this quickly to prevent the generator from shutting down suddenly due to lack of combustible.

Some portable generators have the advantage that they can be activated immediately when a power outage occurs.
One feature that makes these dual fuel portable generators a popular choice is their flexibility.
Have you run out of combustible to power your portable generator?

No problem.

You can always use a different combustible type to perform the generator refueling process.
This way, you can make sure that you never run out of safe and reliable power.

In the following, we will show you the ideal method by which you can start a dual generator and how to handle it.

To be clear, we will go over how to use the dual fuel generator when using two different types of combustible:

  • gasoline
  • LPG (liquefied petroleum gas)

For best performance, follow these steps:

How to start and use a dual fuel generator?

  1. Place the dual fuel generator on a flat ground surface.

  2. Make sure that any electrical charge is disconnected from the generator.

    It is dangerous to turn on or off a generator while an electrical load is connected.
    Therefore, it is recommended that any electrical load be removed before operating the generator.

  3. Release the fuel.

    Turn the fuel valve to the “on” position if you use gasoline as combustible.
    Then move the choke lever to the “100% choke” position.

    If you use LPG as fuel, open the combustible cylinder knob.
    Then turn the LPG valve to the “on” position.

  4. Push the battery switch to the “on” position.

  5. Push the ignition switch to the “on” position.

  6. Perform the electrical start process.

    If you use LPG as a combustible, you will need to move the choke lever to the “75% choke” position.
    No matter what type of fuel you use, you will need to press the ignition switch while in the “start” position.

    Hold the switch in this position until the engine starts.

    Once the engine has started, release the switch.
    If the engine fails to start, wait at least 10 seconds before starting it again.

    If you use LPG as a combustible, move the choke lever to the “run” position once the engine has started.
    Try to move the lever slowly for at least 2-5 seconds.

  7. Start the engine.

    If you use LPG as fuel, move the choke lever to the “100% choke” position.
    No matter what type of combustible you use, pull the starter cable slowly until you feel a level of resistance.
    As soon as you feel a resistance level, pull the starter cable quickly.

    If you use LPG as fuel, pull the starter cord once or twice while the choke lever is in the “100% choke” position.
    Once you feel a few pulses of combustion inside the generator, that means the engine has started.

    You now need to move the choke lever to the “run” position no matter what type of combustible you use.
    As before, try to make this move within 2-5 seconds.
