So, if you are interested in having information that helps you make a good purchase, you should read the following guide to buy the best electric generator on the market.
engine and power
If you want to buy a cheap electric generator, there are many alternatives available on the market, but before making a hasty decision, you need to know that price is not the most important thing in these devices. For this reason, the recommendation is that the engine and power be taken into account, since it will be these components that will lead to its operation being optimized and of adequate performance.
The motor is usually very important, because it will generate the mechanical energy that will be transformed into electrical energy. You can find 2 and 4 stroke engines. In addition, they also vary depending on the revolutions per minute that they can generate and the final power in kilowatts that they will be able to maintain, that is, their capacity. Therefore, according to the needs, a type of motor must be selected.
Type and autonomy
When choosing, it is important to make a comparison of electric generators that includes the type of fuel that moves the mechanism, as well as its consumption and autonomy.
Although there are many mechanisms available, six types can be identified, which are the most commercial. Among them are electric generators with fuel engines, either gasoline or diesel, with tanks that vary according to size and can have autonomies of between 6 and 10 hours. In general, these models have adequate performance and are versatile.
In addition, there are gas, electromechanical, thermal, photovoltaic electric generators, which convert sunlight into electrical energy with solar panels, as well as electrochemical generators, which include those integrated by rechargeable batteries or accumulators of electrical energy and solve before situations that require low power consumption.
In each of the cases, the autonomy can be greater or less. Likewise, the level of consumption may vary according to the mode selected (if this option is incorporated), so some proposals allow it to be adjusted and reduced.
Connection mode and technology
According to the connection mode available, as well as its technology and starting method, different models of electric generators are distinguished. Also, knowing these specs could give you an estimate of how much one costs.
Due to their connection, the so-called power plants can be divided into single-phase and three-phase. Each of these alternatives has different ways of operating and power levels. In the case of single-phase, they are single-phase with a current ranging from 220 to 230V. For triphasic, they are three phases and three alternating currents, which work with 380 volts.
In relation to starting, they can be manual or automatic, while, due to their technology, traditional generators and inverters can be distinguished, which provide considerable savings and adequate system stability. For this reason, they tend to be more expensive, since they also incorporate details that allow better operation and enjoy their advantages, through less noisy systems, small sizes and voltage stability.
Design and protection
Another important feature when making an intelligent purchase decision is to analyze the design based on the needs. These kits are usually heavy and large, but there are some of compact sizes and relatively light weights that can be taken on camping trips. Similarly, certain designs incorporate handles and wheels that facilitate portability and movement, while others include practical structures.
In addition, it is necessary to study the type of protection, since it is convenient that the model to be selected is safe and is enabled with voltage regulation and systems against overload, overvoltage, overheating, underload, short circuits and more.
Frequently asked questions
Q1: How to use an electric generator?
The equipment must be on a flat, stable and ventilated surface. Likewise, the tanks for fuel and oil must be verified, as well as the connections of the devices that will be attached to the generator.
The next thing (it can vary according to the model) is to connect the switch and the fuel tap. If it is manual, it will be necessary to pull the cable. If it is an electric start, it is only enough to activate the mechanism. To finish, it is necessary to close the connections and place the switch in the off option. It is necessary to remember that while the equipment is in use, it must have enough fuel in the tank.
Q2: How to make a homemade electric generator?
To make an electric generator you need a square piece of wood, a skewer stick, a large paddle, 2 CDs and an electric motor. In addition, you must have a ruler, marker, compass, scissors, cutter and elastic band.
A circumference must be made on the cardboard, cut out and glued to the center of a CD, with silicone. To continue, the other CD must be attached to the circumference. Then, you will have to pierce the central part of the CD with the skewer stick and create a rectangular wooden base, which will be where the pulley will go.
Likewise, 5 trapezoids must be drawn, with a height that prevents the pulley from rubbing against the base. These should be glued two by two with silicone and pierce the center of the upper part with the stick.
The process continues by inserting the skewer stick into the center of the CD and fixing it with silicone. Now, you have to glue the trapezoid to the cardboard base and place the rubber band, as well as the pulley made with CDs. In addition, it is necessary to place the other trapezoid at a distance of 3 fingers.
At this point, the skewer stick needs to be cut, and the remaining material will serve as the crank. The palette should also be cut so that it does not rub against the base and open 2 holes. Place a piece of stick in the hole with silicone and insert the crank.
To finish, glue the motor to the base and fit the belt around the pulley and motor. Open the terminals of the LEDs and connect the negative to the positive, as well as the motor cables in the points for connection. It only remains to stick the LEDs on the base and verify that it works.
Q3: How to wind an electric generator?
The winding of modern generators is complex, hence the recommendation is to leave the task to professionals. However, if you want to try it, you have to remove the entire cable, coil by coil (the number of coils varies according to the model) and note the position of each of them. In addition, a new wire must be purchased to replace it and the gauge, as well as the type, will depend on the one that was removed.
The complex part of the process is mounting the new wire, since it must follow a rigorous pattern. Indeed, it is not just about winding, but a specific number of turns must be given and in a certain way, to comply with the values of the established diameters.
Q4: What oil does an electric generator use?
In general, the oils used by these teams are for 4-stroke engines. In addition, it is recommended to use low viscosity type 10W oils. Many brands have specific lubricants for generators and garden machinery can also be used.
Q5: How to convert an electric motor into a generator?
It is possible to do this conversion, but it will not be very efficient in terms of performance and power. These procedures, for the most part, are inconvenient as alternative energy sources, because they require advanced engineering knowledge, so there are certain studies, but few examples that can certify their use as active energy.
Q6: How to repair a gasoline electric generator?
In order to repair a gasoline electric generator, it is first necessary to identify where the fault comes from. If the model is new, it is probably still under warranty, so it is recommended to contact the seller.
If the product has been in use for some time and you do not have knowledge, you should take it to an authorized center of the brand or contact a technician who is in charge of checking the mechanics. This is advised, because the failure can be simple or more complex, such as the replacement of parts that will lead to the opening of its mechanics.
Q7: What maintenance does an electric generator require?
The maintenance will depend on the frequency of use which, if high, will make it necessary to take the generator to a technical service center. In the case of regular maintenance, many of these models require the use of oil and fuel to be able to work, so it is necessary to be attentive to the level of both consumables.
