More and more people are switching to the use of renewable sources of energy such as solar. Unfortunately, this energy is not always reliable or sufficient, considering most solar panels have an efficiency of less than 50%. Besides this, changes in weather patterns make it necessary for one to have a backup plan on the days when there is inadequate sunlight to meet the energy demands of one’s household. Unprecedented power cuts also make it necessary for those on the grid to have an alternative in case of emergencies. If you are off grid, you need not give up the use of modern appliances, especially when you get to choose which fuel to use with the dual fuel generator.
Dual fuel generators are popular because of their versatility. This type of generators allows you to use two different sources of fuel. Should you fail to get one type of fuel, you can easily switch to the other without worrying about the impact of the change. Gasoline is easily available but propane gas is a cleaner, cheaper, and quieter option.
It can be a little overwhelming investing in a generator, especially if you are buying one for the first time. You will probably spend most of your time looking at the different optionsvand wondering what makes them all different if they serve the same purpose. Before investing in a dual fuel generator, it is important to consider the cost, availability of fuel it uses, the sound produced, and more importantly, the fuel efficiency of the generator.

Dual fuel generator for home and garden
Our lives have become so dependent on electricity. Should there be a power outage, everything comes to a standstill. Fortunately, if you have the best dual fuel generator, you will not be worried about your food going bad, especially if it takes longer to have the electricity restored. When buying a dual fuel generator for your home and garden, there are several things you need to consider.
If you will be using the dual fuel generator for your home and garden, it is important to consider the portability of the generator. If, for example, you need to use it on your lawn mower, how big is the space you will be mowing? It will be frustrating if you fail to get to the far end of your lawn because the generator was too heavy or the cord too short. Fortunately, some dual generators come with a wheeled cart which makes them easier to maneuver.
It is also important to consider how powerful your lawn mower is. Some lawn mowers run on lower watts while others need a more powerful source of energy. Your dual fuel generator and lawn mower need to complement each other if they are to work effectively and efficiently. The same goes for any other appliances you plan to run.
If the distance between your home and that of your neighbor is fairly small, you may need to consider the noise produced by the generator when making your purchase.
You also need to consider the appliances the dual fuel generator will need to power if you are off the grid or should you experience a power outage. The size of the engine, as well as the running time of the generator when filled with fuel, should be considered. Some dual fuel generators have one engine while others have two. This will help you plan better, especially if you need to run the generator often and for long hours.
If you love the outdoors and are investing in a dual fuel generator invertor, you need to consider its portability and efficiency. This should be in terms of output and number of hours it can run before it needs to be recharged.
Advantages of dual fuel generators
Dual generators allow you to make a choice on the source of fuel to use. Don’t you just love it when you are given the power to choose? Being able to make the choice on the type of fuel to use based on availability, how environmentally friendly it is and the cost is not only your right, but your pleasure as well.
Generators come in different sizes with different power outputs. You get to choose one which is most suitable for your space and need.
Dual generators reduce fuel storage, which is a hazard. They are cost effective as you can get the best from both fuel types used.
Preparation of the premises for the installation of the dual fuel generator
As you consider the best fuel generator to buy, it is important to also look at where the generator will be stored. This will likely be its permanent space, especially if it is heavy. You need a spot that is far enough to keep the noise away, depending on the type of generator you purchase, yet close enough to power your home. The surface should be flat and level.
If you are investing in a heavy dual fuel generator because you need a powerful one, you need to be certain the area where it will be kept will be able to sustain the weight exerted on it.
It also needs to be kept far away from the kitchen and other areas where fires are likely to occur. The fuels used are highly inflammable.
The storage area should be well ventilated. Avoid storing a generator in an enclosed room as this may cause overheating of the generator, which can be disastrous. Dual fuel generators produce heat as they run. Adequate ventilation allows for cooling as it runs. If you intend to store it in your garage or any other storage facility, ensure there are vents that allow the exhaust to have an outlet.
Invest in plug-in surge suppressors. This will protect your equipment and appliances from any voltage fluctuations especially during the switchover from electricity to generator power.
Models of dual fuel generators
Different models of generators have specifications which meet a particular need. It is important to consider what appliances the dual fuel generator will be expected to power before investing in one.

The range of capacities/dimensions/weight
The power of the dual fuel generators varies between 3100watts and 10,000watts. It is important to note that when looking at the output of the best dual fuel generators, you will receive two output numbers, running, and peak. It is vital for you to consider the lower output as the higher one is usually the starting output. Relying on the upper limit is deceptive and you will be disappointed when you are unable to power your appliances because you relied on the wrong output. For example, the Champion 3400watt dual generator has a starting output of 3400 watts and running output of 3100 watts.
The weight of the dual fuel generators varies. For example, DuroMax XP12000EH weighs 269lb while Sportsman GEN4000DF weighs 94lb. Heavier dual fuel generators tend to have more powerful engines. The dimensions are also bigger, as a bigger engine needs more space.
Dual fuel generators Vs Tri-fuel generators
Dual fuel generators are designed to use two types of fuels, usually gasoline and propane. You, therefore, get to make a choice on which gas you prefer using due to efficiency, availability, and preference. Tri-fuel generators, on the other hand, have the same benefits as dual fuel when it comes to choosing which fuel to use, only instead of choosing between two types of fuel, you get to make a choice between three. In most cases, with a tri-fuel generator, you will be choosing to use gasoline, propane, or natural gas.

With a 50% load, this generator can run for up to 10 hours.
Dual fuel generators maintenance
Whether you use your dual fuel generator regularly or for emergencies, it is important to carry out regular maintenance. This will ensure your generator serves you for a long time.
Stock up on oils and filters. Most new generators need to have the first oil change after running a total of 25 hours. After this, the next oil change needs to be after 50 or 60 hours. Since you never know if there will be an emergency which will necesitate the use of the generator for longer hours, it is best to have the oils and filters in storage.
Always make sure the fuel valve is shut off.
The fuel tank also needs to be empty while in storage to reduce risks. If you use an LPG cylinder as a source of fuel, ensure it is securely kept away when servicing the generator. Ensure the spark plug wire is disconnected. When refilling the generator with fuel, ensure the generator has cooled to minimize risks. You also need to have adequate lighting when refilling to ensure it does not spill over.
Always check the fuel level before you switch on the generator. This way, you can refill the fuel before using, instead of waiting for it to cool before refilling at a time when you will probably need the generator to keep running.
If you run your generator frequently, it is important to pour out stale fuel after some time. This will prevent the buildup of gummy substances throughout. Do not forget to clean out the carburetor as well.
When looking for a dual fuel generator or even possibly a tri-fuel generator, it is important to consider the product reviews. This way you will invest in the best dual fuel generator which will suit your needs. Always consider the wattage of your home appliances.
A Sportsman 4000watt dual fuel generator is more powerful than the Sportsman 2000watt one. Getting it right will save you money and keep you happy for you will have a generator you can rely on.
