What does dual fuel generators mean? How does dual fuel generator work?

Dual fuel generators utilize two different fuels together. These generators usually require diesel to start, due to its low ignition temperature. Dual fuel generators can use two fuels separately or mixed in different proportions.

The most crucial benefit of dual fuel generator is that it can be used in emergencies when only one fuel source is available. These versatile generators are gaining popularity in the US due to their reasonable price and convenience in terms of fuel consumption.

Fuel source:

The choice of fuel depends upon numerous factors, including the price of the generator and the cost of operation. It is essential to consider safety concerns and environmental conditions.

The most common fuels used in dual fuel generators are gasoline, diesel, liquid propane, and natural gas. Gas and diesel are available at local service stations, natural gas is usually used for cooking purposes, and you can use liquid propane in barbeque.

Difference between a Bi-fuel and Dual Fuel Generator:

Dual fuel generators can use two fuels interchangeably as their power source. Usually, gasoline and propane are the most commonly used fuel gases in dual fuel generators.

Bi-fuel generators can use two fuels together through automatic switching or mixing of ammunition. These are less popular and convenient than the dual fuel generators.

Convenience:

Having two fuel options means you can run your generator anywhere, anytime. Even in the days of natural disasters like storms and hurricanes, you will not need to worry about fuel. Propane is easy and safe to store in its storage tanks for extended periods. The fuel tanks can be refilled and exchanged when required.

Wattage:

Before selecting a dual fuel generator, you must be aware of your power requirements. Select a dual fuel generator with wattage matching your power requirements. The wattage in a given generator varies with a given fuel. Gasoline produces higher wattage than propane.

How it produces electricity:

A generator uses mechanical energy to move the electric charges present in the wires. The output current of the generator is created by the flow of electric charges. Modern generators is based on electromagnetic induction. When an electrical conductor is moved in a magnetic field, it produces a variance in voltage. It makes the charges to flow and generate electric current.

Is the propane generator better than gas? What are the disadvantages of propane?

Selecting the appropriate fuel for your generator depends on your situation and circumstances. Several factors determine the best fuel for your generator.

Is propane better than gas?

Propane is better than gas in many ways:

  • Availability: The functioning of the generator depends on the availability of fuel. Emergencies like floods and hurricanes should be kept in mind. Gasoline is readily available in everyday life, but its demand is increased during critical situations. Therefore propane is the only solution.
  • Storage: Gas is usually not stored due to its flammable properties. It also deteriorates if stored for prolonged periods. For using propane as generator fuel, plumbing is usually required. A permanent tank can store propane for indefinite periods safely.
  • Generator Run Time: The built-in fuel tank in the gas generators can save a few gallons of gas, which are enough to run a few simple household devices for a few hours. Constant refilling is required to run the generator for extended periods. The installed propane generators can store enough propane to run the generator for a few days without interruption. The size of a propane tank may range from 1 – 420 pounds (120 gallons) or more.
  • Gas produces more toxins and deposits more carbon in the generator engine, whereas propane is a clean-burning fuel and release fewer chemicals while burning.

Disadvantages of using propane:

  • Propane generators are difficult to manage and maintain.
  • Propane tank regulators can freeze in cold temperatures. Gasoline is more convenient in colder climates.
  • Propane generators produce fewer BTUs per gallon of fuel. Gas generators work more efficiently.
  • Propane using generator produces lesser wattages (at least 10% less than gasoline)
  • The generator run time is lower on propane.

What can a 12,000-watt generator power?

12,000 watts generators can smoothly run domestic fans, lights, computers, TV's, refrigerators, heaters, and other small home appliances. They can also power machines like MIG welder, sump pump, and air compressor. They require proper wiring with the electrical system of the home, to be installed by a professional electrician. Propane or natural gas give power to it.

There are two types of power requirements for all appliances.

  • The starting watts.
  • The running watts.

As a rule of thumb, devices start with taking greater power and then reduce their power consumption. For example, an average size air conditioner requires nearly 2200 starting watts, and this decreases up to 1500 running watts.

If your total wattage requirement is 7500 rated and 9500 starting watts, you should select the generator with 9500 rated and 12000 peak watts.

How to choose the best 12000-watt dual fuel generator?

Buying a 1200 watt generator is a significant investment, and you should do it sensibly. There are thousands of generators available in the market. To select the 12000 watt dual fuel generator, you must consider some essential points.

Fuel Capacity:

The size of the fuel tanks of a dual fuel generator determines the amount of fuel that you can store in the generator at once. This fuel capacity is a measure of a generator's ability to work continuously before requiring a refill.

Power Output:

The power output of generators is measured in Watts. In dual fuel generators, two types of output ratings determine its working power. The rated watts express the overall power output. The peak output represents the maximum available output of a given generator.

The estimated energy intake of the most common household electrical appliances is as follows:

  • Lights: 60 – 600 watts
  • Computers: 60 – 300 watts
  • Room Heater: 1500 watts
  • Refrigerator: 600 watts
  • Sump pump: 750 – 1500 watts
  • Window air conditioner: 750 – 1500 watts

Noise Level:

Generators create noise because they burn fuel inside a cylinder. It is impossible to get a noiseless machine, but one with less noise can be selected. The amount of sound produced by a generator is measured in dBA. If the dBA of a generator is higher, it will produce more noise.

Weight:

Make sure that you are not buying too heavy generators. Heavy machines are challenging to carry and move around if required.

Choice of Fuel:

Most of the consumers prefer dual fuel generators that can use gasoline and propane as their primary fuel. Most of the dual-fuel generators feature a single switch to select the desired fuel.

Battery-Operated:

The battery-operated generators are more comfortable to turn on. They just require to press a single switch to turn on. It is better to have a recoil or manual start option in case the batteries or switch might have some issues.

Warranty:

Most of the manufacturers offer products with long term warranty that is between 2 – 4 years. Buying generators with a higher warranty can save your money. If you purchase a generator without a warranty, you may waste your money on an unreliable product.

Devices with iron parts withstand daily wear and tear and are more durable.

Consider Safety First:

The generator should be compliant with the national safety standards of the United States. Ideally, the generators require EPA and CARB compliance for selling and purchase in all the 50 states.

Auto shut down:

Buy a device that features an automatic shutdown function when running low on oil or fuel. This feature prevents the engine from damage and increases the life of the generator.

Fuel Gauge:

Prefer a generator with a fuel gauge. The fuel gauge will enable you to check the remaining fuel instantly. This feature is helpful during long blackouts.

Conclusion

The best 12000 watt dual fuel generator should be reliable and durable. It should run for an extended time without fluctuation and have enough room for fuel gas storage. The gas conversion should be easy to handle. The 12000 watt generator should be compact and lightweight, supported by firm wheels and handles for easy portability.

Is it OK to leave the propane tank outside in winter?

The cold outside temperatures freeze the propane in the tanks just as they freeze streams and lakes. Though it is not dangerous to leave a propane tank outside in winters, it reduces the propane pressure and will not be used to run your appliances. You can prevent this freezing by using a more substantial capacity tank or by using insulated wraps. Propane tanks can not be stored indoors in any condition, not even in a garage or shed.

Can a natural gas generator run on propane?

Converting a natural gas generator into a propane generator requires a few complicated steps. Performing any one of them incorrectly may result in disaster. Running the generator on propane will reduce the efficiency of power generation. Propane is much cleaner and quieter than natural gas. It burns without producing noise and excessive carbon dioxide.

Can a dual fuel generator run on natural gas?
