Getting electricity for lighting or for the use of power tools with best generator in places. Where there is no access to the grid or where power cuts are frequent. With the inverter models you can also power any electronic equipment, such as computers, tablets, televisions, or the usual household appliances.
Investing in best generator becomes a real nightmare when thousands of unknown parameters, complicated mathematical formulas, infinite types and models, even advanced engineering notions! Sometimes, due to the exaggerated number of variables that manufacturers establish. That’s happens with selecting a best generator, a classic among complex tools. And is that bad advice can end with our investment directly in the garbage, either by recommending us insufficient information for our needs or instruments too powerful.
So in this article we will talk about electric generators in a clear, simple way and with specially emphasis on what is really crucial when getting the services of a generator: what functions are intended.
Why we use best electric generator?
Whenever you need electricity without alternative to the grid, you will need a best generator. Having one at home, especially in rural areas, is a good investment. Here are some of their uses:
- Handle power tools on rural farms and areas away from villages.
- Install a lighting system in country houses or building sites.
- allow lighting or use tools in homes in works without electrical connection.
- Support your home’s emergency power supply in the event of blackouts or breakdowns.
- Provide the necessary energy in a campsite.
How best generator works?
Its operation is based on the obtaining of electrical energy from another energy:
- Mechanical energy: with gasoline, diesel or gas engine generators.
- Starting with photo voltaic solar energy: with solar generators.
What are its parts?
The motor: single phase or three phase, 2 or 4 stroke
It provides the strength and power for the alternator to turn and make its function. There are generators with diesel or gasoline engine, and 2 or 4 stroke. The best powerful generator or groups usually have 1,500 revolutions per minute (r.p.m.) and those of sporadic or moderate use of 3,000 to 3,600 r.p.m.
- 2-stroke engines are the least powerful and noisy. They work with gasoline and oil mixture.
- 4-stroke engines, also known as OHV, operate on gasoline or diesel and have greater power. There are 3,000 r.p.m. And 1,500 r.p.m.
- Single-phase: its power is small; Serve for lighting and common uses, as they provide a single-phase current similar to that of the 220 volt mains. They are larger and noisy than three-phase and need an external starting element as they cannot start alone.
- Three-phase: they are smaller than the previous ones in relation to the powers that can generate, greater than the single-phase. They do not require additional booting mechanisms and can be used with more powerful machinery. They are less noisy and vibrate less than single-phase.
The cooling system
To prevent overheating of the engine when it has been operating for several hours, it must be keep cold. The process can be:
- By air: a large fan carries cool air to the engine.
- For water or oil: a radiator system with fluids that are cooled by means of a smaller fan.
Chassis or frame: muffle the noise
The structure that supports the engine and all equipment. The ground support must have supports protected with rubber, to cushion the movement and produce less noise.
Deposit: more or less auto system
You have models with tank for plastic or metal fuel. Also of greater or smaller size, with more or less autonomy of use, therefore.
What type of Generator do I need?
Regardless of how your engine is – diesel or gasoline – generators can be conventional or inverter.
They are used for use with portable electric tools, such as drills, concrete mixers, irrigation pumps, etc. If you are going to use it for the feeding of a certain number of light bulbs, choose a conventional best generator, suitable to the power you need. It is always recommended that you have a good automatic voltage regulation (AVR).
Suitable if you want to connect electronic equipment, such as computers, video, air conditioning, television … as they offer a stabilized power guarantee similar to at least that of conventional electric current. The inverse technology avoids voltage deviations above 1%. This will not cause damage to the equipment with sudden changes of voltage. These generators are smaller, weigh less, produce less noise and consume less fuel, since the best generator itself regulates its power according to the needs to which it is subjected to each apparatus.
Photovoltaic generators produce electricity free thanks to its inexhaustible source of energy: the sun. They are completely independent, ecological and do not produce noises. Their price is higher but you have to keep in mind that they will not require later hydrocarbons purchases, nor will they need maintenance.
How to choose best generators for home
Without a doubt, the main question that we must resolve before considering a best generator. Whether to buy an electric or other else. And it is also the stage that creates more confusion among those who want to buy a best generator. There are many websites that try to offer us an absolute solution in this respect, but the only truth is that there is no universal machine. Before acquiring a best electric generator, each person must analyze their own needs
Here are the main factors that influence the performance of a best generator during its different uses.
It is the main indicator in which we must look. It refers to the total power in watts that a best generator is capable of supplying. For a generator set to work properly, its output power must be equal to the sum of all electrical appliances (appliances, tools or light bulbs) that we are going to connect at the same time. For example, if we are going to connect a 500 watt radiator and five 100 watt light bulbs, we will need an electric generator of at least 1000 watts of power.
Maximum power vs nominal power: another important section when taking into account the powers of our electrical appliances is the maximum power and the nominal power. All appliances that work with some type of motor or compressor (inductive), such as washing machines, refrigerators or drills, need extra power to start. It is important that we take into account that this type of maximum power multiplies by three to the usual power of the device, and that if we do not add it to the total power count our electric generator will not be able to support it. Following the example above, if we use at the same time the 500 W radiator, 3 100 W bulbs and a 350 W drill, it will be necessary to have a best generator set up to 2000 watts.
Generating set depending on the signal dispersion
The signal dispersion is the percentage by which the continuity of the electrical current generated by the generating sets can vary. This indicator is important if we are going to connect devices with electronic boards, such as televisions, computers or other appliances that require constant voltage and little fluctuation. There are generators with automatic voltage regulators included (AVR), although the best machines for feeding sensitive electronic devices are Inverter generators.
Diesel, gasoline or gas generators?
The type of fuel that feeds our electric generators is also a factor to take into account, since it depends on important aspects such as noise, working time supported or price. There is not one fuel type better than another, as both have positive and negative parts, but we have compiled the main advantages and disadvantages of gasoline and diesel generators to make your choice easier depending on our needs.
Gasoline generator set
Appropriate if used occasionally. They are quieter, and give us the option to choose between 2 strokes, ideal for lighting, or 4, suitable for supplying larger appliances. However this type of generators consume more fuel and are design for short periods of work.
Diesel electric generator
If many hours are to be used, the option is diesel, especially if they are also used for many days in a row. Diesel engines have a lower attire, lower consumption, are more durable and less maintenance, but generate more noise and more fumes. The storage of diesel fuel is not a problem.
can be operate with supply gas, for static locations, or with a gas cylinder, allowing mobility. Their great advantage is that they do not make noise and are very safe.
Another basic aspect when choosing our best generator are the revolutions capable of developing. Mainly, the generators that we find in the market are divided into generators that work between 3000 and 1500 revolutions per minute. The former are very economical devices for occasional work that do not require large periods of continuous work.
For their part, the 1500 rpm generators are able to operate without pause for complete days without resentment. This is an advantage when we need a generator at full performance for long periods of time, but are also machines that require greater economic outlay.
Once we have broken down the main characteristics that we need to know about the purchase of an electric generator, we will analyze the most outstanding tools in the market for current generators.
The most basic and most important function that an best electric generator should be able to carry out. When electric blackouts besiege our home or when we want to enjoy decent lighting in a country house far from the electricity grid, it becomes necessary a best generator that can provide us with a reliable point of light. Fortunately, the generator sets for lighting are the most economical and affordable on the market.
We have made a selection of the best electric generators for your home, with different powers depending on the use you need to give it. Follow these steps to know which generator to choose:
- A) Identify how much power you need. Before buying a best generator it is necessary to evaluate the power requirement and check the power of all the devices you want to connect at the same time to the generator. It is important to determine the starting power of each appliance, which will always be equal to or greater than the working power.
To establish how much power you need, you must have all the starting powers of the devices.
- B) Identify what power quality you need. The choice of the regulation technology is really important so that your electronic equipment is not damaged.
The AVR is a system of automatic voltage regulation. The quality of the energy generated, allows to connect to the generator set the majority of electronic devices.
The INVERTER technology uses a microprocessor that regulates the output of energy to be stable and constant. The INVERTER technology is able to adjust the engine speed depending on the power required, thus reducing fuel consumption, pollutant and noise emissions. Thanks to its lightness and compact design, it offers great ease and versatility of use. Generators equip with INVERTER technology are design to supply power to all electronic equipment with sensitive components.
- C) Location of use and emission of noise. The sound emission level will depend very much on where the generator is to be used (construction site, residential area or traveling sales post …). The unit of measurement is dB (a). For example, for a traveling stall, a soundproof generator would be the best option for the comfort of both workers and customers.
According to all of the above of best generator, we ask ourselves the following factors:
Fuel: May be Gasoline or Diesel. Diesel fuel is more economical, if I only want a small Generator, it will suffice with one of Gasoline. Diesel generators are best generator that can work continuously, for days, months. Gasoline generally only work 4 ~ 6 Hrs.
Fixed or Portable: If it is fixed is because you need the continuous service or what is called Prime Power, they are Generating Sets in general with a very large Electricity Charge in KVA, as for example of 17 KVA. Or they can be used in Stand By mode if there are sporadic cuts, you can feed a large number of devices. Important the fixed ones usually have the transfer switch to power the electrical grid of the place, without this device cannot connect the Generator directly to the house. If they are portable they are devices of small loads like of 1000 W, 3500 W, among others. Ideal for carrying in the hand, or even a little bigger but with wheels and still portable
2T or 4T: 2-stroke generators are noisier but consume less fuel, give more autonomy, are more economical. The 4-stroke times are quieter but more expensive, however they have a longer lifespan.
Inverter or AVR Technology: This is a very important feature, since this technology allows a generator to behave in a stable and non-fluctuating way, fluctuations in voltage or voltage can damage your devices.
What do our references with great brand support so that you can invest yours?
This best generator costs only a few hundred dollars. And for that price you cannot get more. It produces 3300 watts of power performance. That amount of energy should be enough for most uses. With 3300 watts you can power most of you appliances. There is the best lightest generator, weighing just under 100 pounds which is gasoline from the generator power by the 4 gallon fuel tank. With the fuel tank can run for a maximum of 8 hours, which is good, given the amount of energy it produces.

Power, fundamental aspects
To calculate the power you need you have to take into account the sum of the powers of all the devices that you intend to use at the same time. But you must differentiate between:
- Resistances: such as bulbs, toaster, iron, heaters, etc., which is indicate the each element.
- Inductive powers: such as that needed by devices with spinning motors, such as washing machines, pumps, refrigerators, portable electric tools, etc. In this case, the calculation must be different, since these machines when starting need more power than during their operation. There are tools that need at the time of starting up to 4 times the nominal power of use.
What is frequency?
You will see that in the best generator sets the manufacturer indicates a frequency of operation in Hertz (Hz). The electrical impulses generated by the alternator is of 50 Hz.
The origin of the electric frequencies Why 50 and 60 Hz?
Although it may now seem that there has always been a single frequency for the transportation of electrical energy, in each of the two main zones of influence: 50 Hz for Europe and 60 Hz for the United States, this has not been the case. We will take a tour of the history of the frequencies that have been used.
In 1891, the engineers at Westinghouse, Pittsburgh, agreed and made the final decision to consider 60 Hz as the frequency of the future, and during that same year, the engineers of Allgemeine Elektrizitats Gesellschaft (AEG) in Berlin selected the 50 Hz.
Since the beginning of the times of electricity used not as fun, but as a safe method of lighting houses, walks or as a method to power electric motors in factories and produce a mechanical movement that freed us from the expensive And very inefficient mechanical transmission systems: using axles, connecting rods, pulleys and gears that were being used in those years of industrial revolution, the frequencies used have changed from 40 and 53 Hz in Europe and from 133 + 1/3 and 125 Hz in the US At 50 and 60 Hz respectively.

Alternator: electricity is produced here
It is the part of the machine in charge of transforming the mechanical energy into electrical energy of alternating current. It is able to feed, according to its power, the same equipment and tools as with the power of the electric network.
How are the calculations done?
- Make a list of all the elements you are going to use and add their real power to use. Look at the consumption plate of each item or appliance. It also has the necessary power for starting, which is often referred to as a “starting peak”.
- If you have machinery that expresses your horsepower on steamboats (HP), you should keep in mind that 1 HP equals 736 W (W).
- Add 20% more of the power that has resulted, so you foresee future uses that you do not contemplate now. In this way, you guarantee a longer period of use and do not force the generator to the maximum.
- Calculate the hours that will be working. If it is sporadic and never more than 8 hours in a row, it will cost you one of 3,000 r.p.m. (revolutions per minute). If you are going to be working many hours and you are continuously interested in a 1,500 r.p.m.
Where to place a best generator?
Keep in mind that, because it is a motorized machine, it has to be in a place with natural ventilation, without humidity and easy access.
We advise that both gas oil and gasoline stores in approved drums and never more than 30 liters.
A best generator need routines maintenance that will extend their service life and guarantee of their performance.
- on first use, let it run without connecting it to electrical or mechanical equipment for a long time. Then you can use it to its maximum power.
- Change the oil when recommended by the manufacturer and always with the proper oil. Normally a first change must be made after the first 40 or 60 hours of use; then the change can be made after longer periods of time, between 100 and 150 hours. If you use it very little, you should change the oil every 4 or 6 months, even if you have not reached the number of hours of operation.
- Check the condition of the air filter. Clean it every so often.
- Change the gasoline and diesel filters when recommended by the manufacturer.
Starting of best generator
- Fill oil to the proper level recommended by the manufacturer. You must set the type of oil indicated in the instructions.
- Open the fuel cock and refill with the required amount. Do not confuse yourself with fuel, diesel or gasoline; if the gasoline is mixed with oil (in 2-stroke engines), make the appropriate ratio.
- The generator is an electric starter, check that it has the battery connected.
- Go for manual starting, pull the rope several times, with power but with a short movement, until the engine starts.
- If the engine is very cold or has not been used for a long time, open the starter and then close it as you reach the correct temperature.
Let’s round up!
Both of these cheap generators are good. One would expect they are bad because they are cheap. But there is nothing wrong with them. Yes Durostar DS4000S is a bit heavy and not so portable, but if we consider the fact that it gets over 3000 watts for a few hundred dollars, it is well worth it. Anyway, there are wheels that you can attach to it so you can move anywhere with you. If you want quieter cheap generator, then WEN is right for you. It is small, CARB and EPA compatible, and spark arrester makes it safe for camping. Getting one of these best camping generator will be a good investment.
