Dual Fuel Generator Selection Guide
Now that we have introduced you to the seven best dual fuel generators, how do you go about choosing the right one for your needs? This buying guide is going to summarize some important factors to consider before you choose a dual fuel generator.
i. Your power needs
The kind of generator you want is going to be determined by the amount of power that you need. Check your appliance and decide what kind of dual generator is going to fit you. If you only have some essential tools, then probably you don’t need a lot of power. You will, however, need a high-power generator if you intend to use your generator for your entire household power needs.
Portability is an important consideration, especially if you intend to use your generator for outdoor events. Some generators will have integrated mobility kits while in others, they come as accessories meaning you have to mount them later on. Check their functionality to ensure that they are sturdy enough to handle the weight and that they can work on all terrains. The handles should have soft grips for comfort and easier storage.
iii. Noise Level
Noise and sound, in general, is measured in a unit called decibels (dB). The higher the number, the louder the unit is. Generators are generally noisy machines, but some models operate at a much quieter level. A dual fuel generator with 60 dB or below is considered to be a perfect choice for campers or use in close quarters.
iv. Ignition Types
Duel fuel generators will have different starting systems for both gasoline and propane. For gasoline, most models have an old recoil system, but some are ignited electrically. Propane, on the other hand, is always ignited electrically with a turn of a key. So when a calamity comes knocking, all you have to do is to choose the fuel that you prefer or that is available and ignite the system.
v. Monitors and Indicators
It is crucial for any generator to provide the correct information about oils levels, fuel levels, and the overall status of the unit. Most dual fuel generators have integrated various monitoring styles, which includes LED screens and indicator lights. The indicator lights help to monitor engine oil level, engine overload, and generator readiness all at once.
LED screens, on the other hand, will do the same thing but will do so more precisely. Also, they will display the number of work hours, which will help you decide when to carry out detailed maintenance.
vi. Safety considerations
Since this is basically a personal mini electric power station, you will want to be sure that several safety systems have been put in place before you use your generator. A good model should have overheating protection, overload protection, and a low oil shutoff mechanism. All these systems will keep you safe and keep your generator running smoothly.
Dual fuel generators have been the favorite portable generators for a reason. They save you in many unforeseen situations, making them a great invention of all times. They are value packs, convenient, durable, and change your life for the better. Also, these generators can be a long term investment for your home or RVs.
The fact that they are both gas powered and propane powered generators makes them very adaptable and flexible. They are also portable, providing the fastest way to get back into action in the event of a power outage. You only need to wheel it out, power it, and you have got an alternate power source.
There you have it! Great insights on the best dual fuel generators. This is a valuable investment, so take your time to consider all factors before deciding on the dual generator that matches your requirements.
