Which generator do I need for work

A generator is an indispensable tool for working in many cases-but how to choose the most suitable generator? The complete guide is before you.
We live in the electric age-there is no working site today that does not depend on electricity. But what to do when working on a site that does not have a regular power supply?

One solution is beyond battery-powered tools, but this solution has limitations – for example, it is not always possible to find the necessary tool in a battery version. The second solution is of course work with the help of a generator –

A mobile device that generates electricity in the standard that is acceptable in the Home Power Grid, and allows working with “ordinary” tools anywhere and time. Proper selection of the generator will optimize the work,

Save glitches and headaches and avoid wasting time. And time, as you know, is worth money. A lot of money.

But how to choose the appropriate generator? Read on > >
1. Power – the higher the generator, the larger and more expensive it will be, but on the other hand, too weak a generator will limit you in work or will not allow you to work at all.

That is why it is important to understand what power you need. Consider with what tools you work in parallel usually,

And connect their declared suppliers (the power is registered on the device as a number with the letter W at the end – the average power for a fumigator, for example, is about 800 watts).

The amount you received multiplied by 1.5 to give a little “sapphire”, and also because at the beginning of the operation, for a short moment, electric tools consume power higher than their declared power.

Tools with a compressor – compressor or refrigerators, for example, consume especially high power when starting, so if you have such a tool the power of the generator should be at least 3 times the power of the tool with the compressor.

See the table attached to the multiplication ratio for different types of tools.

2. Diesel or gasoline-in light generators, with a power of 2-3 kilowatts (1 kW = 1000W ), usually you will find only generators that have a gasoline engine, so there is no deliberation.

Diesel engines begin to appear in more powerful generators-they are slightly heavier than gasoline-powered and more expensive generators, but more resistant to prolonged work.

That is why the choice should be in accordance with the intended use and therefore if it is a generator that will work whole days from morning to evening, day after day, it is recommended to choose a diesel generator.

For occasional and short works, you can settle for a gasoline generator.

3. Ordinary generator, stabilized AVR or inverter – sorry for the Chinese, but this technical matter has an important meaning. The generator generates electricity by rotating the coil inside a magnetic field.

The result is the so-called” alternating current”, as in the household outlet, when the frequency of the current depends on the speed of rotation of the coil inside the magnet (determined by the speed of rotation of the motor) and the height of the voltage depends on many factors.

That is why an ordinary generator will generate electricity at a voltage and frequency that are not completely constant.

It’s okay if you want to turn on a filament lamp, for example, but not if you want to turn on more sophisticated devices that are sensitive to the stability of the voltage and frequency.

That is why ordinary generators, not stabilized, become rare today, and usually appear only at the lowest price levels.

And still – if you plan to operate a power tool with a generator, it is important to make sure that it is stabilized. There are two methods of stabilization – AVR and inverter. Catalog generator stabilizer AVR.

The first method involves an electronic component that the electricity produced by the generator passes through it, and it “cuts” the voltage to the correct value in the event that a higher voltage is received.

Thus, it protects the devices connected to the generator from too high voltage, which can damage them. But this component can not stabilize the frequency of the alternating current-a matter that may harm sensitive electronic devices.

This problem is precisely solved by the inverter-it is a digital module that converts the alternating current produced by the generator into a direct current (like the one that provides a battery),

Then converts it back to alternating current – at precise voltage and frequency, without deviations.

The result is the so-called” pure sine ” or pure sin-check the devices that you plan to operate with the help of the generator and check whether they require it.

Today more and more devices are sensitive to the”quality of electricity” they receive.

The inverter generator is more expensive, naturally, but today the gap compared to the AVR generator is getting smaller, so even if at the moment you do not need the stability of the voltage provided by the inverter, it is worth considering investing in one.

4. Electric or manual-electric starter, as in a car, is of course more convenient but requires an accumulator and a starter. These items cool the generator and add to its weight.

That’s why when choosing a generator, you need to take into account the pros and cons of each type of starter and choose the type of starter that is more suitable for the nature of your use.

If you use the generator rarely, it may be worth giving up the starter and accumulator (whose life may be shortened due to its long storage – and of course it costs money to replace it).

The same is true if you are forced to carry the generator to a relatively large distance during work. On the other hand, if during an average working day you start and bleed the generator many times,

The advantage of the electric starter is obvious. It is important to note that in some generators that have an electric starter, there is a manual backup, so there is nothing to fear of”getting stuck” with a generator that does not start due to an empty or malfunctioning battery.

5. Traditionally generators with engines made by American, Italian, German or Japanese companies are considered the most high-quality, but today there are quite a few Chinese manufacturers that produce engines of quite good quality.

However, it is important to remember that high – quality engines cost money, even when they are made in China-a very low price is a suspicious sign.

6. A generator is a tool that requires regular maintenance and repairs, so when buying a generator it is especially important to choose a generator “with dad and mom”, one that is imported by an old company and sells a quality service set that has proven itself. A generator that is disabled because of a lack of spare parts can cost you in lost working days. After buying, be sure to take care of the generator according to the manufacturer’s instructions, to keep it in optimal working condition for years.
