Is Dual Fuel Generator Worth It?
A dual-fuel generator assures that you will have electricity no matter what happens outside. Natural calamities such as hurricanes and earthquakes can cause gasoline supplies to be disrupted. If you rely on that one form of fuel, you may be limited to what you have at home but the dual fuel option will save your life because it has the second choice to select.
Dual Fuel Vs Single Fuel Generator
Dual-fuel and single-fuel generators work similarly, but they differ in the kind and number of fuels that may be used to power the machines. Natural gas, diesel, gasoline, liquid propane gas, and solar energy can all be used in these systems.
A dual power generator may switch between multiple fuel kinds automatically to extend its runtime, whereas single fuel generators can only utilize one fuel type. The switchover occurs based on fuel availability and the most efficient fuel source at the moment.
What To Look for When Buying A Dual Fuel Generator?
There are several aspects to consider while shopping for a dual-fuel portable generator.
You may perhaps have explored a few alternatives. However, while selecting a dual-fuel generator, you must properly investigate its qualities and weigh its significance about your application.
There is a good probability that some features provided in a particular product will not be required in your circumstance. This detailed shopping guidance is provided to avoid such a scenario.
You may learn about each of the qualities in detail here and select which ones you require the most in your dual-fuel generator. For an appropriate decision, make sure you read the buying guide carefully. There are several aspects to consider while shopping for a dual-fuel portable generator.
1. Fuel Capacity
Dual fuel generators feature specialized fuel tanks to store fuel since they are fueled by gasoline and propane. Each gasoline tank has its unique capacity, thus they are not all the same. This capacity is expressed in gallons. A 10-gallon tank, for example, can only carry 10 gallons of fuel at a time.
Having a large-capacity tank will benefit you in a variety of ways. You won’t have to bother about recharging the generator every now and then if you have a large fuel tank, and you’ll be able to enjoy uninterrupted power output. Remember that huge gasoline tanks are only available as a premium option.
2. Rated and Peak Output
When purchasing a generator for backup power, you must consider the power available at the generator’s output. On each dual fuel generator, there are two separate output ratings: rated and peak output. However, these figures differ for gasoline and propane. As a result, each generator will produce four distinct output values.
This can be perplexing, but don’t be concerned. When purchasing a generator, if you simply examine the peak capacity for both fuels, you will automatically receive a greater operating watts output. For example, if you select a high peak value for gasoline, you will also receive a higher peak value for propane as well as greater running watts.
3. Generator Size
This is an important consideration if you want to move the generator around for different purposes. If you are contemplating a heavy-duty generator, make sure you evaluate the size and weight of the generator.
Heavy-duty generators are often larger and heavier than low-powered generators. As a result, transporting a heavy-duty dual-fuel generator, especially while the fuel tank is full, might be difficult. On the other hand, if the generator is small in size, you will observe that the power capacity and fuel capacity are both reduced.
4. Noise Levels
Internal combustion of gasoline or propane powers dual-fuel power generators. Because this combustion is a continuous process, generators emit a large quantity of noise when they are in operation. It is impossible to locate a fuel generator that runs completely silently. You can, however, use a dual-fuel generator with a reduced noise rating.
If the generator is creating too much noise, it might cause a lot of disruption, which can harm your application. As a result, you should always look for a generator with a lower noise rating. Also, bear in mind that if you use propane as your primary fuel, you won’t have to worry about noise levels as much because propane runs quietly.
5. Engine Efficiency
Each dual-fuel generator contains an engine that utilizes gasoline or propane to create energy. While various power output numbers may appear identical, fuel consumption will vary due to engine efficiency. Engine efficiency essentially shows how effectively fuel may be spent to generate energy.
If the engine is inefficient, you will run out of gasoline quickly. You will also be exposed to a large number of hazardous exhaust gases as a result of faulty fuel combustion. As a result, even if you choose a low-power engine, be sure it is economical in terms of fuel consumption.
