For what purposes did you need a diesel generator in St. Petersburg? You must confidently and clearly answer this question in order to choose the most optimal option for yourself.
Autonomous or reserve unit you need?
Autonomous generator is needed during the absence of other power sources.
If the electric supply comes from the industrial network, and the purchase of the generator is just a preventive measure from possible disconnects, then you will need a backup source.
We determine with power
Firstly, its value will depend on the power. Choosing a power source by power close to all connected electrical appliances is likely that an increase in their number will lead to overloading the generator apparatus. But too high power will also not be the right solution, as it can negatively affect the engine during its operation. The most optimal and recommended option may be a load of 35-75% of the rated power.
We clarify the place of operation
If you purchase a generator for autonomous use, then it should assume work in the open air, and the temperature spread is allowed from -50C to +50C. When buying a backup option, the installation is located in the room or a special block container, with temperature modes from +5C to +50C.
The duration of the power source
A significant duration of the diesel generator can be achieved in two ways. The first – the volume of consumable fuel tanks increases, and the second is automatic supply of oil and diesel to fuel tanks, from storage via fuel wires.
Autonomous diesel installations are not designed for a long time: sources that have a power of 30 kW operate, as a rule, no more than 8 hours. Stations with the least capacities have a one -time period of use 4 hours. But this type of generators allows you to install a fuel tank, a much larger volume, which will allow it to work without a stop of about 24 hours.
Reserve electric generators can work continuously without maintenance for a whole day. True, it should be clarified that it is possible to extend the time of its functioning using additional equipment, the installation of which, intends to increase the period of operation to 240 hours. Such an improvement will cost a penny, but it always justifies itself in economically in a short time.
Uninterrupted power supply
This indicator is related only to reserve power sources. The short -term absence of stress for most of them does not pose any danger. For example, if you switch power sources from one to another, then this will not lead to a breakdown of the mechanism, or to the accident, or to any other unpleasant consequences.
If you are concerned about the fact of possible breakdowns, then buy a reserve power source complete with the UPS, but keep in mind that this block will cost many times more expensive than the generator itself. Therefore, in such cases, you must have a weighty technical and economic justification of such an acquisition.
Types of alleged loads
Before buying a diesel power source, you must immediately decide on which types of electrical equipment he will have to work. The load can be industrial and household. Industrial includes power or motor activity, and household is mainly responsible for lighting functions.
If you answered all questions as accurately as possible, you can profitably and choose the right generator you need.
