The Best Dual Fuel Generator Options – best portable generators of 2022
A review of the best dual-fuel gas-to-gas generators – All about building, tools and products for the home
Dual-fuel generators, also called hybrids, can run on two fuels, usually gasoline and propane sometimes natural gas. Having both options provides more flexibility in terms of operating costs and storage.
What are dual-fuel generators and which one is best to buy
Gasoline is the standard type of fuel for generators, but it has certain drawbacks – it’s more expensive. Propane is often cheaper, which lowers operating costs, it can be stored indefinitely, and it even reduces noise levels.
For some, a longer total run time is already enough to buy a dual-fuel generator. Depending on the model, you can seamlessly switch between fuel supplies, which greatly increases the amount of time you can keep the generator running before you need to turn it off for refueling.
Here are the ten best hybrid generators, ranging from lower output inverters to more powerful models. Which one meets your power needs?

Pros and cons
Types of generators.Advantage and their difference.
A generator is a type of device that generates electricity or converts one type of energy into another. A generator is designed to provide autonomous electricity.
There are several kinds of generators and each of them works on a different kind of fuel, and they all have their differences and their advantages.
The gasoline generator
The gasoline generator (so-called mini power station) is a small unit used to generate electricity. It is used when there is a need for electricity. The work is based on the conversion of fuel energy into electricity. It is used for supplying electricity to objects that do not have a connection to the central power grid. If necessary it can be used in facilities where the central power supply is frequently and for long periods. Type models are designed with comfort and compactness in mind, if necessary, the delivery of the unit in the right place the location will not be very difficult, since the gasoline generator is not heavyweight it is not difficult to move from object to object.
Mini power plant (gasoline generator) is widely used in such facilities as an agricultural farm, construction sites. To provide electricity to a private home with an unstable supply of electricity, a garden plot without connection to the mains, garage, street market stall, you’ll need a not large portable unit with a working capacity of 5 – 6 kW, which will provide the work of the refrigerator, cash register and lighting. Quite often began to use and when traveling on vacation in auto camping (vacation in a tent), in this form of recreation of his work allows the fan to work, a small refrigerator and is even possible to watch TV.
Before you buy a gasoline generator it is important to determine how much power you need and for what purpose you will use this unit. There are two types of electric generators: two-stroke and four-stroke.
A two-stroke gasoline generator
A two-stroke gasoline generator is not a large capacity unit designed for use in domestic conditions, its comfortable model will not take up much space. But this power is not enough to provide electricity to your entire country house and all the appliances that you want to use or to use in the work of the small carpentry workshop. For these purposes, you will not circumvent the Four-stroke Generator – this model of power station will suit you completely as it has a capacity above 6.5 kW and will provide you with stable operation of the power grid.
You will not need any special engineering knowledge to start using such equipment. It has a simple design and is easy to use. Refueling the engine will not be a big problem, and gasoline for its uninterrupted operation is always on sale.
The price of the generator, working on gasoline is not high, an inexpensive unit, which can afford to buy, everyone who wants to buy a similar technique.
And yet it is worth recalling that it is important for what purposes you will use a particular type of gasoline generator. If you want to use the generator as the main electric power supply. Then it is better and more convenient for you to buy a diesel generator.
A diesel generator is also designed for constant electric power generation. This unit has a high level of operation, while it is bulky and heavy. Such a generator should be installed where it will work long, much and almost continuously. The type of such a generator is capable of working in an autonomous mode, producing electricity.
The purchase of a diesel generator is necessary for those, who own a small shop for the production of any products, it is also useful in a carpentry workshop, a sawmill, at construction sites, where all the construction tools that need to be connected to electricity will be running on this generator. In general, such equipment is needed wherever there is no connection to the electricity grid. It is very convenient to transport it to any place.
To work such a unit in the room, you need to have a separate angle with good ventilation output, because the generator needs the supply of cold air and diversion of hot air flow, which will come from the running apparatus, as well as ventilation is needed to ventilate the exhaust gases.
Diesel generators, as well as gasoline generators have their power.It is important to determine how much power you need electricity, and for what purpose you will use this unit. With not a high output of electricity you need a single-phase, it is for household networks, where the load is not great, the output gives 220W. But for production purposes, you will need a three-phase power source. They have a cooling system, it helps them to work uninterruptedly for a long time.
The capacity of standard generators with output of 5-6 kW is enough for a residential house with average energy consumption. Country cottages with electric heating, autonomous water supply and pumping sewage need a power plant with a capacity of 10-12 kW and more.
What is better to buy a gasoline or diesel generator?
The gasoline engine is designed for 2500-3000 thousand motor-hours. As for the diesel engine, its resource is much higher, while it consumes less fuel. Diesel generators have a number of advantages – economy, durability, cheaper and safer fuel.
Conclusion: When using a 1 kW gasoline generator, you can turn on the TV, lights and refrigerator. It is better not to clean the house with a vacuum cleaner, because the starting power of this device is at least 2.4 kW (1 600 W x cos φ 1.5 = 2 400 W)
General placement recommendations Some general recommendations include placing the standby generator where the prevailing wind will carry the exhaust away from the house. at least 2 meters away from openings such as windows, vents and doorways.
3 kW generator = lamp + kettle + refrigerator + TV + pump
Reference table for calculating generator power.
Appliance Power, Watt
Hair dryer 450 – 2000
Cooler 150 – 600
Circular saw 1800 – 2100
Electric kettle 1000 – 2000
Categorically not allowed
Connect the generator through an ordinary household socket with a plug and plug wire and disconnect the input circuit breaker.
Do not connect the generator through a switchboard using a circuit breaker switch.
What’s better with a gasoline or diesel generator?
It has been proven by experience that under equal operating conditions and an average load of 75%, a diesel generator consumes 30% less fuel. This feature is the main factor that gradually erases the difference in the cost of gasoline and diesel power plants
Diesel generators do not need a large amount of fuel, they are economical.
They run for a long time.
