Dual Fuel Generator Buying Guide

Buying a dual fuel generator is not a cheap and easy task. Therefore, you must be absolutely mindful while buying one. Given below are a few things that you should consider before choosing the right dual fuel generator for yourself. 

Fuel Capacity

The fuel capacity of dual fuel generators has a wide range from 2 gallons to up to 10 gallons. If you are in requirement of longer run times, you should definitely opt for generators that have a high fuel tank capacity. However, in other cases, small tanks work too.

Since propane is stored in pressure canisters, you can use as much as you want of the fuel once you attach it to the hose. Therefore, if you do not generally require too much run time at one go, buying small generators is feasible.

Power Output

The peak power output of each generator is the one that it can provide at any given time. In this article, that number is provided for each generator. The huge range of energy outputs of dual fuel generators is from 1000 watts to 12000 watts. However, each generator produces different levels of energy when running on gasoline and when running on propane.

The amount of power you generally require is the defining factor of how much power output you will require. 

Size 

While buying a generator, you must always consider the size and weight of the machine. Since most heavy-duty generators are heavy and bulky, you must be sure that you have ample space and permanence to install them. 

If you require to move the generator that you have installed, you must always remember that a full tank makes heavy-duty generators almost impossible to move. This is an important factor to be taken into consideration. 

Noise Levels

The power of dual fuel generators is created by the internal combustion of propane and gasoline. This combustion often produces too much noise while operating. While no-noise functioning generators do not exist, the level of noise in some generators is significantly low.

You must always consider buying a generator that does not produce a lot of noise. Most generators fall under the noise level of 75 to 80dB. If the generator that you’re going to buy is louder than that, then you might face issues in the future. 

The noise of combustion is almost unbearable. However, you do not have to worry as much about sound if you are going to use propane as your primary fuel source. This is because, in comparison to gas, propane has a slightly silent performance.

Summing Up

Buying a generator can be a life-changing event. With the help of a generator, you will always have power-backup at your workplace or household. Since dual fuel generators do not confine the user to only one source of fuel, its usability is even higher. 

The availability of great generators is scarce in the market. However, choosing the right one should not be dependent on availability but on usability. The list of products and buying guide in this article should help you make the right choice for your power needs.
