Mood On  Before Buying  Dual Fuel Generator

When choosing your dual fuel generator to power either your home or your job, it’s important to understand what you’re looking at. This is why we have gathered together the best information for you to make your decision.

Regardless of affordability or capability, there are a few main points to consider. Let’s take a look at what makes a dual fuel generator the best.

Power Ratio

Power is always the most important aspect when dealing with a generator of any kind. The last thing you want is a weak generator that can’t power all your necessities. The first thing to think about when buying a new generator is how much wattage your stuff requires. Are you just running some tools? Or are you using it to power your entire house? Is it just a backup for necessities or do you want the generator to power everything for long durations?

The best thing we can recommend is that you make a full list of all the tools, appliances, and other electrical things that you need to run when your power isn’t working. This will give you a full breakdown of the wattage required. And using this list, you can find a dual fuel generator that is suitable for your needs.

You also want to pay attention to what the wattage output is depending on if you’re running the generator with gas or propane. Sometimes propane runs at 10% less power. This means you definitely want a little extra overall power so that there is some leftover regardless if you use gas or propane.

With atypical dual fuel generator that outputs at least 4000 Watts, you should be able to run the essential appliances in a small setup or in an RV. However, if you have a larger household or a big job site that requires massive amounts of power, you don’t want anything smaller than a 10,000-Watt generator. This will give you an uninterrupted power supply. And if you’re really willing to fork out some cash, you can get a giant generator with a maximum of beyond 12,000 Watts.

Control Panel

Any good generator is going to come with a quality control panel. It is absolutely critical that you can monitor the status of your generator. You need to be able to constantly see the fuel level, the runtime, the wattage, and what the maintenance intervals are.

This is all going to be viewed by you through the control panel. And any good generator is going to have indicator lights, LED displays, and maximum information for you. You want an intuitive control panel so that you don’t end up running out of power by accident.

Another thing to consider is if the generator has its control panel integrated with other protection systems. For example, having a low oil shutdown is critical to protect your generator in case the fuel level becomes dangerously low. This will automatically shut off the generator so that you don’t burn through the last of your oil without meaning to.

There are a few other things to consider, such as overload protection, circuit breaker, a voltmeter, easy manual operation, and of course overheating protection. It’s also great if you have a few different ways that you can start your generator. For example, using a pull recoil or an electric start. Some models even come equipped with a remote start, so you don’t have to go outside to start your generator.


A lot of people miss this – but don’t!Receptacles are super important. Never overlook or miss the number of receptacles on your generator. Almost every model is going to come with a few standard 120V outlets, and this is sufficient for almost every household appliance. But if you need more, you definitely want to double check.

If you own a business, if you are using heavy-duty industrial tools, or if you have an RV, you are probably going to need at least one 240V outlet or even an automotive 12V DC terminal for your vehicle. Always check what kind of outlets you’re going to need and then make sure they are included in your dual fuel generator.

As a final note, another thing that’s going to be important is the sound your generator makes. This is for a few reasons. But overall, you don’t want a loud generator. You don’t want to bother the neighbors, you don’t want to give away the fact that you have power in an emergency situation, and you don’t want to be the annoying person on the job site with a screeching generator.

The best thing we can suggest is to get a quiet generator that outputs less than 65 decibels. Anything over 65 decibels is going to get noisy and annoying.This is something you have to think about more with a dual fuel generator than with a gas generator.

Another thing to keep in mind before we close out is that dual fuel generators are indeed more expensive than generators that only use gasoline. This is why gas generators are so much more popular. However, if you do choose a dual fuel unit that is reasonably quiet, you will be much happier knowing that you have more efficient power options and a more reliable source of power when things go wrong.
