Inverter gasoline generators differ in the types of engines. They use two- and four-stroke engines. A mixture of gasoline and technical oil is used as fuel. MTBF in two-stroke engines is within 500 hours. Accordingly, such an inverter gasoline generator is useful only in the country, where it is necessary to provide lighting, including several bulbs or when going out into the countryside. Therefore, these types of power plants are not widespread.
Four-stroke generators gasoline invertor DDE
European and American manufacturers are focused on the release of power plants with four-stroke engines. These are gasoline invertor DDE generators belonging to the class "professional". The camshaft is in their lower position, and the duration of operation is in the range of 8 hours for one day. Automation is designed to stop the engine when reducing the amount of technical oil. These are durable power plants. According to the passport data, they provide uptime between 3000-4000 hours.
Continuous operation time and fuel tank capacity
These values are interrelated. The fuel consumption and the capacity of the tank in which it is stored determines how long the inverter gas generator will not be interrupted, but will continue to generate electricity. When discussing this characteristic, it should be recalled that refueling the fuel tank in working condition is unacceptable. If you spill a little oil or gasoline, the risk of fire becomes too high.
In those situations where the need for continuous continuous operation of the power plant is very high, it is recommended to install an additional or backup fuel tank. But here it should be noted that the total daily duration of work cannot exceed 8 hours for most models, and 10 hours for some. Based on this mode, the calculation for the frequency of oil changes is 50 hours. If the inverter gasoline generator is operated only once or twice a week, and only 2 hours, then the oil filter and oil must be replaced every 150 hours. Given the national characteristics of our market, these standards should not be adhered to. In order for the machines to work long and well, it is better to change the filter and oil earlier than the period specified in the instructions and carefully select the oil. And another filter should be attached to the reserve fuel tank, which will separate water and impurities from gasoline.
Transition from 220 to 380 V
Choosing an inverter gasoline generator for a country house or production with single-phase consumption, a single-phase power station should be preferred. However, based on the fact that their power is limited to 30 kW, this may not be enough.
If there is equipment requiring three-phase current, then you need to buy the appropriate power station, but in order to equalize the load, you need to make a separation of power into three lines. This is very important because three-phase generators have a high sensitivity to phase imbalance. But if the power consumption of the equipment is small, then it is better to give preference to a single-phase station having a system combining the phases. Then the generator will operate in 220 V mode, and if necessary will go to 380 V.
