What Is a Dual Fuel Generator?
Dual fuel generators have grown in popularity in the recent past thanks to their reliability and flexibility. But what are they?
These are generators that use two types of oil- often diesel and a natural gas such as propane or gasoline. They have bi-fuel engines that use the two types of fuel interchangeably.
Switching between the two fuels is done automatically and is based on the type of fuel that is the most efficient depending on the activity done.
These generators are ideal for people who need emergency backup power in their home in the event of power outage and those who want a generator that can provide power when they are in outdoor environment.
What To Look for in a Dual Fuel Generator?
To choose the dual fuel generator, there are two main factors you need to put into consideration;
Power and size of the generator
When shopping for the best propane generator, these are the two main important factors to consider. Most models come in large sizes, but that doesn’t mean you cannot find the best dual fuel portable generator that can power home appliances and items while you are in an outdoor environment.
You need to ensure that the generator you are getting has enough wattage to power the available appliances in your home or in an outdoor environment you are camping.
If you want to use the generator for off-site projects, you will probably have to consider portability as you will be carrying the machine from the job site.
Fuel storage capacity and temperature
This is another important factor to consider when buying a dual fuel generator. Often, gasoline is used in most generators because it is affordable. With gas, it doesn’t last long enough as heat makes it evaporate. That’s why most people prefer propane.
