Dual Fuel Generators – Disadvantages They Come with
Although there are numerous benefits that come with a dual fuel generator, you will often have a few drawbacks too. For example, one of the drawbacks happens when the unit is running on propane. If you use propane, then it will have a slightly lower power input.
Also, another disadvantage of dual fuel generators is the fact that they can be a little heavier. When you’re using them on propane, they have to stay connected with a propane tank, which makes them much heavier. This makes them a little less portable, which can be quite annoying when you need to transport the unit.
Some units can also be a little loud. Of course, it depends on the brand and multiple other factors, but if you purchase a cheaply made product, you risk having to deal with a lot of noise, which isn’t too pleasant. That’s why you need to look for one that will not produce a lot of noise and is more of a high-quality quiet portable generator.
The gasoline usage of the unit can bring a little disadvantage as well. Basically, if you want to store your generator without using it for a whole month, then you need to run the tank dry if using it with gasoline. This fuel, especially ethanol E10, tends to dry the air a lot, becoming more corrosive to brass, aluminum, and others. It’s not the best thing in humid climates, so make sure you run the tank dry if you have plans of storing the machine for a month.
Differences Between Conventional and Inverter Dual Fuel Generators
If you’re looking for something to provide you with power during an outage, then you probably already searched for options. Most likely, you stumbled upon two options: conventional generators and inverter generators. As such, you most likely asked yourself what differences there are between the two. You’re not to blame, after all, since the goal is finding the most suitable option.
Well, here are a few differences between conventional and inverter dual fuel generators:
A top-rated inverter generator will normally be less noisy compared to a conventional generator. This is because inverters come with built-in special mufflers, as well as sound-dampening technology. This helps them operate more quietly in general. Compared to these, conventional generators tend to be a little noisier, due to the heavy load, which causes the engine to throttle up.
Unlike inverter generators, conventional ones are often the more pocket-friendly option. When you need a lot of power, conventional generators will be much more affordable. Due to working on newer technology and having a lot of advantages, inverter units will be pricier.
In every state, there are specific regulations when it comes to the accepted amount of greenhouse gas emissions from a generator. Depending on where you use the unit, some regulations can be quite strict. Inverter generators thankfully don’t produce a lot of greenhouse emissions. They are more environmentally friendly. Conventional generators that have fewer greenhouse emissions are a little harder to find.
In terms of portability, both conventional and inverter generators can be portable. However, among the two, conventional ones can be less portable, due to the fuel tank. Because they have a large fuel tank, they will be harder to move around, as they are bigger and heavier overall. For portability, you will notice that these units often have handles and wheels. As for inverter generators, they are much smaller and have less weight as they don’t have huge engines. Because most models have less than 100 pounds, they are easier to carry around.
It’s known that inverter generators are a little less powerful than conventional generators. As such, they have a limited maximum output. In general, they have a rating between 1,000 and 4,000 watts. On the other hand, conventional generators can generate way more power, going from 500 watts to up to 50,000 watts and even higher, depending on the model. They are much better in this regard if you need more power.
Another difference between these types of generators comes with the current they produce. For instance, conventional generators will usually have a messier sine wave, as they only produce AC electricity. They are suitable to use for most electrical appliances. However, they tend to cause harmonic distortion, which can be harmful if you have sensitive devices that you use with it. Conversely, inverter generators will produce electricity in 3 phases, respectively high-frequency AC to DC and back to a stable AC. The cool thing with these is that there is less harmonic distortion, making them safer to use with multiple appliances, even more sensitive ones.
To make up for the lower power output they come with, inverter generators will usually allow parallel connections. This makes two separate inverter generators of the same model able to be connected, so they can offer a double amount of power. As conventional ones are less portable and more powerful, they do not offer a parallel connection.
What You Should Keep in Mind when Purchasing a Dual Fuel Generator
When you’re looking for a dual fuel generator, there should be a few features to keep in mind, particularly if you don’t want to end up with the wrong model. Well, let’s take a look at the features you should consider.
Needs and Intention
Before starting your hunt for the best dual fuel generator, you have to establish why you need one in the first place. List all the reasons that you would use the generator for, no matter what they are. Is it for situations when you’re left without electricity during an outage, or you’re planning to use them for camping or outdoor activities? You have to look at all of these and determine whether you should purchase a unit like this or not.
Power and Size
When looking for such a generator, you cannot overlook the size. In general, dual fuel generators will be larger, mostly because of the fuel tank. In any case, large models are probably the best ones anyway. At the same time, it doesn’t mean you cannot find one that is smaller yet still has amazing features.
When you look for a generator like this, consider the weight, portability and total wattage. These are more important, with generators of any size.
The runtime is a very important consideration, especially if you want to ensure you will get enough power throughout the entire outage you are possibly dealing with. Well, runtimes depend on the amount of fuel in the tank, so the tank size will affect the runtime as well. Most good models have a runtime of up to 10 hours if you use enough fuel. It goes for both gasoline and propane. Therefore, make sure you look for a model that has a long enough runtime so it doesn’t stop when you need it the most.
The cool thing with a lot of dual-fuel generators is the fact that they come with control panels. This will allow for easier control while the unit operates, making sure you get the best performance. In addition, control panels will sometimes offer you a way to see the amount of fuel in the tank and some other things, so you know what settings to make according to that. Therefore, you should consider a dual fuel generator that has a control panel.
Another important consideration is the noise level of the unit. It’s ideal to look for one that is quiet. While it may be hard due to the engine and overall operation of the machine, you should be able to find one that’s less noisy than the average generator. Check customer reviews to find out how it performs in the noise department.
Automatic Controls and Safety
Since safety should always come first, you need to consider this aspect. Basically, a lot of these generators tend to produce fumes, and because of that, you need enough space and an open location to run the generator. It shouldn’t be kept inside a garage or your house, because the fumes can even be fatal.
In addition, you should look for a generator with a cutoff switch. This will make it stop working in case you forget to check the oil. So, if there’s low oil or it overheats, the unit should automatically shut off.
Weight and Portability
Most of these units are very heavy and less portable. Even if they have wheels and handles, a big tank will make them harder to move. Depending on how often you need to transport the product, you must consider the weight and portability. Look for a less heavy one if you need to use it for camping or other activities away from home.
As the name suggests, there are 2 types of fuel for dual fuel generators. You can use gasoline or propane, but which one should you pick? Well, it all depends on which one is the most convenient option for you. Gas can be a good option if you need to run multiple appliances at once. But it can be risky in case of spillages, and it has a limited shelf life as well. Propane, on the other hand, is cheaper and cleaner too, but it’s nonrenewable and doesn’t perform well in cold weather.
Therefore, consider all pros and cons before settling for a type of fuel. Also, if you’re looking for something more eco-friendly, you can always go for the best solar generator.
Dual Fuel Generators FAQ
Let’s take a look at some commonly asked questions about these units.
- Are dual fuel generators safe for things such as computers or other sensitive electronics?
