Purchase of a electricity generator
What do you have to consider when buying a electricity generator? Which systems are used?
How do you choose a electricity generator?
A electricity generator is a machine that can produce in electrical current. These devices are very useful for those who are often in places where there is no electricity or the lack of energy is switched off the electricity. A camping vacation, organizing a trade fair, working on places where there is no electricity, or a simple winter service are activities that would be difficult without this device, if not impossible. In many cases, the devices are used to use on construction sites and out There are different types of generators that differ in relation to the fuel used for energy generation, the supplied performance, the speed of rotation, frequency stability and the noise level. So how do you select the power generator that is most suitable for your needs? You have to know first What service is required for the operation, and the preferred Fuel choose.
How can you avoid choosing the wrong generator?
If we choose a model that has too low performance compared to the maximum absorption capacity of the devices or tools that we want to operate, it will not be able to deliver the required electrical output.
Selecting the right performance is very important.
On the contrary, if we buy a generator with a high performance compared to our need, we will also neglect the ratio between electricity consumption and performance in addition to the excessive acquisition costs, since we have operating costs for the generator that is much higher than the required service that could be covered by a properly dimensioned generator.
Have you ever started a scooter after being in the garage for a long time? Does he start the first time, not?
The same happens with a generator with a petrol engine that has been in the basement for a long time and has not been used for a long time.
The starting difficulties can be attributed to the starting properties of the engine and the fuel, which worsen slightly over time.
It is recommended to only choose generators with a diesel engine.
Inverters, voltage controllers, speed controllers
In an earlier article we talked about power units with converter technology and speed control, i.e. about stabilized aggregates.
One of the special features that distinguishes an apartment from other electrical consumers is the presence of numerous sensitive consumers, just think of television appliances, consoles, kitchen machines, etc., all of which are very sensitive to voltage fluctuations.
A electricity generator, as you can buy it for CHF 199.- in the hardware store, to use for the power supply of electrical and electronic devices that may be worth 30 times as much as it is a bit like the safety of an expensive Harley Davidson entrust a thin, miserable nylon tire.
Inverter generators are a good solution in terms of electricity quality, the variable engine speed, the good fuel consumption and the tolerable noise, but they are equipped with petrol engines so that I exclude them for the reasons mentioned at the beginning, and they are also relatively expensive if you are for decides something reliable.
Power generation units with a diesel engine with 3000 revolutions per minute are ideal if you have little space available, but such engines are not electronically adjustable, with some exceptions, so that they are not ideal for direct care.
A power generator with a diesel engine with 1500 revolutions per minute would be the perfect solution, for the following reasons:
- It can run for days without any problems.
- It is quieter than the generator with an engine with 3000 revolutions per minute.
- It can be equipped with an electronic speed controller.
- It has a greater relocation and therefore reacts better to the stress. (Nobody ever says that
- It usually costs more, but is also worth a lot more.
- It is sold by experts so that you (usually) receive excellent customer service.
The performance
How do you find the power generator that meets your needs?
For the Home use are portable power generators with one Power of 1 to 3 kW usually sufficient. For construction sites, on which the absorption is important, generators become From 10 kW to over 25 kW needed. For the current generators, the performance decreases with increasing height: the generator loses 9 % of its performance every 1000 meters. A generator reaches its maximum efficiency when it 80% which nominal output stated in the technical data in KW is operated: If my devices collect 2 kW together, a 2.5 kW generator is required to cover the above-mentioned need with 80% of its maximum performance.
Inrush: What is it and how is it calculated?
The insertion current is the current strength that is required to start the tool connected to the generator. Specifically, the switch -on stream is a power tip that the generator has to create the moment he is supposed to start our devices. In order to determine whether a generator has the required starting performance, you can use a simple formula: absorption of the top performance specified on the type sign of the power tool Multibled by example: Electrical drill 1200 watt times coefficient 2 = 2400 watts the required generator performance.
Definition of the nominal output
This is the performance that the generator can continuously submit over a long period of time. It does not guarantee maximum efficiency, since this is only specified in 80 % of the nominal output (see above).
Definition of maximum or top performance
This is the maximum performance that the generator can give for a short time. It differs from the top performance in that the former is a technical feature of each individual generator, while the latter depends on the tool connected to the generator and represents the performance that is necessary to start the tool itself. It is good practice that manufacturers specify the two types of performance. If only one service is specified in a flat rate without specifying whether it is the nominal power or the maximum performance, the user is inevitably misled. It is advisable to rate the only specified service as a maximum service.
Example: electrical drill 1200 watt times coefficient 2 = 2400 watts the required generator performance.

This is the performance that the generator can continuously give over a long period of time. It does not guarantee maximum efficiency, since this is only specified in 80 % of the nominal output (see above).
The electrical absorption of electric tools: let's look at an example together
The difference between the KVA and KW of a generator can be expressed in kilowatts (KW) or Kilovolt (KVA). Knowledge of the difference between watts (W) and VoltaMere (VA) is useful to determine the; application area; of the electricity generator more precisely. The unit of measurement for electrical performance. The KW is 1000 watts. The KW measures the "real power" of the generator. Definition of VoltaMere The voltampere measures the "electrical sham performance". The KVA is 1000 voltampers, which results from the physical laws and is explained in detail.
Noise level
Most conventional devices are very loud and therefore also problematic from a legal point of view. Due to the excessive noise pollution in the cities, regulations were issued that prohibit the exceeding of a certain noise threshold for the human ear. Choosing a low -noise machine is the best option to avoid health problems and unpleasant recall actions. An example of this is the Hyundai generator, which is equipped with cladding and acoustic panels that significantly reduce the intensity of the noise during operation.

For Ohm's consumers, the power of the power generator should be about 25 % higher. For a TV with 300 W, 375 W should be planned. Inductive consumers often need four times as much start -up current. A 500 W pump should be connected to a 2,000 W power generator.
Of course, these are guidelines. That is why we first show you a table of ordinary consumers that you usually use - even when camping.
Which electricity generator would be appropriate to the performance also depends on very different factors.
Differentiation between ohmic and inductive consumers
In order to be able to estimate the necessary performance of the power generator, you should Differentiation between ohmic and inductive (capacitive) consumers know.
- Ohmsche consumer are those devices that convert electricity into heat or light. Typical examples from this device category are light bulbs, electrical radiators or simple kettle. In order to be on the safe side and not let the generator run to maximum performance, we should plan around 25 % reserve for this device class.
- Inductive consumers are devices that have to drive an electric motor. Hence the Start -up current As part of the switch -on current, which is necessary for the start of the built -in engine, many times higher than the permanent performance (Nominal current). In general, modern inductive consumers need three to four times their continuous performance at the start. In older devices in this class (about a 20 year old refrigerator), this can even be six to eight times as high.
- With large engines of a water cleaning system, it can even be ten times.
