For a small problem, which is undergoing construction and finish will be enough model for 6 kilowatts, larger cottage require the acquisition of the device up to 15 kilowatts. Number of People generator phase, to work a little bit to understand the types of generators, pay attention to the issue of the number of its phases. And this is one of the most important criteria for choosing an independent source of electricity. When using the on-site single-phase electrical wiring and the generator need to buy single-phase. But the three-phase model require compliance with conditions of approximate equality of power to all consumers at different phases. This difference should not exceed 20-25%, while the three-phase generator will work properly. Synchronous and asynchronous generators that question rarely pay attention, however, it is quite important when using highly sensitive to the voltage drop apparatus.
If any in the house there, the answer is unequivocal: we must take asynchronous generator, which supports voltage with high accuracy. For emergency power and lighting villas, building sites, as well as the refrigeration units should be fine synchronous generators. Except They allow you to connect devices and equipment with the reactive power up to 65% of the nominal value, which is asynchronous model can not provide: their limit 30%. Types of motor generator main question of this paragraph can be formulated simpler: diesel, gasoline or gas? The answer depends largely on operating conditions. Affordable and effective option is to gasoline running, usually on gasoline Ai92. It is relatively inexpensive, compact, is quiet, and fuel for it is quite accessible anywhere in the country.
