The first is to estimate the mini-power plants. To do this, calculate the total power electrical devices that will be connected to the installation. (There is a special technique that takes into account factors including electrical appliances. It is similar to that used in the calculation of power system from a centralized source of electricity.) It should be taken into account: for mini-power station is better if its capacity is 20% higher than the estimated total. (The above diagram shows the capabilities of various household appliances and tools, allowing to assess the needs power generators.) If the consumer does not intend to limit power consumption during operation of an independent source, and plans to use all the benefits of civilization, the task easier – as a starting point for calculating the electrical power is taken, a dedicated provider of centralized energy to electrical installation. In the case of three-phase circuit electrical wiring and, accordingly, with a three-phase mini-power plants it is important to observe the approximate equality of the electric power consumers in the different phases (the difference should not exceed 20-25%) to avoid the 'phase imbalance. " Range of generator sets in the Russian market is very broad, and the consumer is free to select from a virtually unlimited range of capacities – from tenths of kVA to several CF-A.
Thus, we can to satisfy any request, regardless of the extent of energy a country house. Another important criterion – the type of powertrain. In favor of a gasoline engine shows its low cost.
