Buyer’s Guide to Portable Dual Fuel Generators.

Since now you are quite acquainted with the various generators in the market, you might be facing a dilemma on which one to choose. You will surely have some options in your mind, but how do you settle for the right one?

Hence, we bring to you our detailed buying guide that outlines all the parameters you must consider and all the properties you must study for accurate purchase. 

1. Outline your power needs:

Any generator purchased is based on how much power you wish to extract. If you wish to utilize a generator to power your entire house, you need to purchase a high-powered model that produces at least 5,000 Watt. However, for lesser requirements, like powering only a few appliances, a smaller model along with a low power rating, i.e. preferably a 2000 Watt generator is more feasible.

2. Know the exact generator size you require:

Your generator size comes into play if you have to move it around. So keep in mind to choose a generator after thoroughly reviewing your power requirements as its size and weight form an important criterion. 

Heavy-duty generators can be tedious to be carried around as compared to the smaller models. Meanwhile, a compact-sized generator exhibits a lower power and low fuel capacity, Hence, it is easily portable.  

3. Fuel capacity should be taken into account:

Dual fuel generators, as the name suggests function with efficient fuel tanks to house fuel. These generators are usually run by gasoline and propane. The fuel tanks are distinct and have their storage capacity, which is measured in gallons. These large fuel talks are available with premium options. 

It is always advised to purchase a tank that can store a high quantity of fuel to reap the benefits in several ways. Re-filling the tank is a repetitive task, but with high capacity tanks, you have to do it fewer times. You also don’t run out of power when you need it the most, owing to a large quantity of fuel in these tanks. 

4. Pay attention to rated and peak output. 

While you buy the generator for power cut crisis, you must carefully view the two different output ratings that accompany every portable dual fuel generator. This is also known as peak and rated output. However, with the two gases, i.e. gasoline and propane, the values vary. Hence, you will notice four values for the power output on each generator. 

At the start, this may seem confusing but here is a trick you need to know. You have to only pay attention to the peak capacity for both fuels while purchasing a generator. It works relatively and you end up getting a higher running value. 

To gain more perspective let’s say, in generator type A, if you choose for a high peak value for propane, you automatically achieve a higher peak value for gasoline as well as a higher running watts output. 

5. Keep a check on the noise level. 

Dual fuel power generators work on the principle of internal combustion of gasoline or propane. This combustion is an ongoing process, and hence, there is quite some noise produced when the generator is running. While you cannot find a generator that is devoid of noise, you can look for a portable dual fuel generator with a lower noise value. 

Having a low noise rated generator is important as this disturbing noise can affect your applications and also give you a hard time, when in operation. It is recommended to utilize propane as your primary fuel among the two. This is because propane undergoes silent combustion. 

6. Engine efficiency is important. 

In every portable dual fuel generator, there exists an engine that combusts propane or gasoline to produce energy. You have to realize that the fuel consumption might vary, unlike power output values. This is credited to the efficiency of the generator’s engine that determines how productively each fuel can be utilized to generate the output. Hence whether it is a low power engine or a high-power engine, you have to ensure efficiency in regards to fuel consumption

Engine efficiency is important due to two main reasons. One, without it your fuel will be exhausted very quickly. Second, an inefficient engine produces a large number of harmful exhaust gases due to improper combustion. Thus, engine efficiency allows you to save up money on fuel and save yourself from inhaling harmful exhausts. 

Frequently asked questions

Here are some frequently asked questions that might have occurred to you as well. Have a look.

Q1. Which fuel is better suited to be as a primary fuel: gasoline or propane? 

Answer: While both the fuels have their merits and demerits, propane is comparatively cheaper and combusts silently. It has a higher shelf life and is easier to get, even during emergencies. However, gasoline is otherwise widely available and burns with greater efficiency, even in lower temperatures.  

Q2. Can I connect the portable generator to my home? 

Answer: It is highly dangerous to directly connect your generator to any electrical system due to the risk of electrocution and equipment damage. Hence, you must install a transfer switch by a professional electrician to prevent any damage. 

Q3. Why is changing oil better than refilling oil in the portable generator?

Answer: It is recommended to change the entire amount of oil instead of refilling it at regular intervals. This increases the efficiency life of the engine and prevents damage to the components as the engine oil gets destroyed over time due to the heat from the engine. You can treat it as a similar case of the oil boiling in a pan that cannot be re-used beyond a certain point.

Q4. Why does the generator need to be grounded?

Answer: The grounding of portable generators is an important safety measure to avoid all possible risks of electrocution. To achieve this, a copper rod is driven into the ground and copper wire is attached from this rod to the frame of the generator. You have to follow the entire grounding instructions specific to your particular generator. This will protect you from the threat of electrical shocks. 

Q5. Is it okay to run or vent out a generator in an indoor area or a garage that has an open door? 

Answer: The primary rule of operating a generator is running it in an open area with a high amount of airflow and ventilation. If you run a portable generator indoors, it can prove fatal or result in respiratory problems due to the inhalation of carbon monoxide and other harmful gases that are exhausted.  

Q6. What do I do, if I am not using my generator for a long period? 

If you plan to not utilize your generator for a certain period, follow basic storage precautions. These include draining the fuel tank, adding a fuel stabilizer, and cleansing the carburettor.
