Starter type
Method of starting the electric generator engine. To start the internal combustion engine (petrol or diesel, see "Fuel"), it is necessary to turn the engine shaft in any case; this can be done in two ways:
—
Manual. With this method of starting, the initial impulse is transmitted to the engine manually - usually the user needs to pull hard on the cable that spins a special flywheel. The simplest in design and cheapest method of starting, from additional equipment it requires only the cable itself with a flywheel. On the other hand, it may require the user to apply significant muscular effort and is poorly suited for high-power units.
—
Electric starter. With this type of start, the engine shaft is rotated by a special electric motor, which is called a starter; the starter is powered by its own battery. This option for starting the generator power unit is the easiest for the user and requires a minimum of effort. Depending on the implementation of the electric starter, it is usually enough to turn the key in the ignition switch, press a button, turn the handle or rotate a special drum, etc. The power of modern starters is sufficient even for heavy engines, where manual starting is difficult or impossible. Also note that an electric starter is required by definition to use the ATS autostart (see "Features"). On the other hand, additional equipment affects the weight and cost of the unit,
...and sometimes quite noticeably. Therefore, such starting systems are used mainly where they cannot be avoided - in the aforementioned heavy equipment, as well as generators with ATS.Fuel consumption (50% load)
Fuel consumption of a petrol or diesel generator when operating at half power, and for combined models when using petrol (see “Fuel”).
Fuel consumption usually increases with load. However, generator efficiency is not always linear - fuel consumption may vary disproportionately with different loads. In this case, the approximate amount of fuel consumed by the generator when operating at half power (50% of the rated power) is given. Knowing the fuel consumption and tank capacity, you can at least estimate how long one fill-up will last.
Noise level
The noise level produced by the generator when operating in normal mode. The less noise the unit makes, the more comfortable it is to use, the closer it can be placed to people, but the higher its price, all other things being equal.
It is also worth considering that generators with internal combustion engines are, in principle, quite noisy equipment. Thus, even the "quietest" units produce
< 70 dB - this is the volume of a conversation in tones from medium to high. Accordingly, it is recommended to install the device remotely from the place of use. At the same time, we note that the noise level is not directly related to the power: for example, among units of 80 dB and more, there are both heavy and relatively low-power models.
