How To Choose A Dual Fuel Generators?

You need to know about the generators to get the right generator. There are many generators in the market and online stores, you need to understand the common terminologies and everything before you buy one.

If you don’t know anything, then you will end up buying something useless. So, before buying a product, you should know about the features and functions.

But, if you are new, and you don’t know anything about the generators, then don’t worry because we are going to tell you everything in detail. This buyer’s guide will help you get the best dual fuel generator that you need. We will discuss the terminologies and features and try to explain everything in detail. Let’s start.

Fuel

The common fuel in most dual fuel generators is propane and gasoline. The gasoline is expensive as compared to propane, but it provides more BTUs per unit of volume. For gasoline, there is a tank in the generator, you need to check the capacity of the fuel tank.

A large tank provides more run-time of the generator. You will find tanks usually in the range of 3-9 gallons or more depending on the generator.

Propane is excellent, you can connect the tank to your generator. You can store propane for a longer time as compared to gasoline. Further, it does not harm the internal engine.

In most generators, it is very easy to switch between propane and gasoline. There is usually a switch to switch the fuel. In some generators, you can switch the fuel in running condition without interrupting any work.

Peak Watts and Running Watts

These are the two important terms that you need to know about the generator. These will give you an idea of how much load the generator can bear. Peak watts of a generator are the power that the generator can supply to devices when they start.

At the start, some appliances like motor and other things take more power and after a few seconds, the consumption power drops, and they consume the rated power. So, such appliances need extra power at the start.

Therefore, the peak watts are always mentioned that tell how much surge power the generator can supply. Peak watts are often called surge watts.

Running watts is the power that a generator can supply continuously to appliances. We told you, after some time the appliance consumes the rated power only, so you can see whether the generator can supply that running power or not. Running power is also termed as rated power. Running watts of a generator is always less than the peak watts.

For example, you need to run a few appliances and they are rated as 3,000 watts. But at the start, the appliances require 3,200 watts. So, you need such a generator that has running watts more than 3,000 watts and peak watts more than 3,200 watts. If any of them is lower than the required, the generator will not power the appliances. Therefore, it is necessary to know these two powers so you can have an idea of how much power you will get to run your appliances.

Power Produced in Gasoline and Propane

In dual fuel generators that use propane and gasoline, the power provided by gasoline is more than the power you get on propane. If a generator has peak watts 3,000 watts and running watts 2,800 watts on gasoline, then on propane, it will provide fewer peak watts and running watts. The difference can be of a few hundred watts. Make sure to check that as well.

Outlets and Receptacles

There are different types of outlets present in generators. You find AC outlets of 120V in most generators, but some generators also have 120V/240V outlets. The outlets can be of different types such as duplex outlets, twist lock outlets, RV ready outlets, 12V DC outlets, etc.

If you want to use the generator with RV, make sure it has an RV ready outlet and it has enough wattage to power your RV. Some generators also have 12V DC terminals to charge batteries. In inverter generators, you will find USB ports as well.

Noise Level

You cannot find a generator without a noise. Generators produce noise and you cannot eliminate it. But you can select a generator that has low noise. Generators usually have noise levels from 59dB to 76dB. The noise level also depends on the power that the generator is producing. You can search for generators that have lower dB values. You can see the following table to understand the intensity of the noise.

Noise In DBExamples
60Noise of normal conversation
65Piano Practice
70Noisy restaurant/Hair dryer
75Alarm clock /Dishwasher
80Vacuum cleaner/busy residential road

From the table, you can get an idea of the noise level. The noise level also depends on the distance. If the distance between you and the generator is more, then the noise will be low. The noise level above 85dB is dangerous and it can harm your ears. You need to have ear protection above 85dB.

Running Time

The running time of the generator depends on the capacity of the fuel tank, the load connected to the generator and some other factors. Manufacturers mention the number of hours that the generator can work on the full fuel tank when a certain load is connected.

For example, a generator can work 10 hours on a full tank of gasoline at 50% of the load. Therefore, this time will decrease when you connect more load. At a load of less than 50%, you can use this generator for more time. Running time is usually defined at 25% or 50% of the load.

Before you buy a generator, you should check the running time. It will give you an idea of whether you can use such a generator for long power outages/camping or not.

Safety Features

To keep your generator safe and sound, there should be some safety features. You will find circuit breakers in all generators because it is essential. There are different circuit breakers for AC and DC. In case of any problem, the circuit is interrupted by these circuit breakers. Further, they are visible so you can reset them easily.

Low oil indication is also an excellent safety feature. In the case of low oil, wear and tear occur inside the engine. So, it is necessary to keep an eye on the oil. Therefore, there is an indicator light in most generators that alarms in case of low oil. In some generator, there is a low oil shut off that turns off the generator automatically.

Starting Mechanism

The starting mechanism of the generator should be easy. We recommend getting such a generator that has an electric starting mechanism. You just need to push the button and the generator will start automatically. Anyone can start the generator without applying force.

There should be a recoil starter as well to start the generator if the electric start button is not working.

Warranty

Usually, you will find a 1 to 3-year warranty with the generators. Some companies also offer an extended warranty, you can choose if you need it. With the warranty, you also need technical support through call. So, make sure the manufacturer offers call support.
