How to choose the right gasoline inverter generator for domestic needs?

Inverter-type gasoline generators differ in engine types. They use two- and four-stroke motors. A mixture of gasoline and technical oil is used as fuel. The value of time between failures in two-stroke engines is within 500 hours. Accordingly, such a gasoline inverter generator is useful only in the country, where it is necessary to provide lighting that includes several light bulbs or when going out into nature. Therefore, these types of power plants are not widely used.

Four-stroke gasoline inverter generators DDE

European and American manufacturers aim to produce power plants with four-stroke engines. These are gasoline inverter DDE generators belonging to the "professional" class. Their camshaft is in the lower position, and the duration of work is in the range of 8 hours for one day. Automation is designed to stop the engine when the amount of technical oil decreases. These are solid powerhouses. According to passportdata, they provide 3000-4000 hours of trouble-free operation.

Continuous run time and fuel tank capacity

These quantities are interconnected. It depends on the fuel consumption and the capacity of the tank in which it is stored, how long the gasoline inverter generator will not be interrupted, but will continue to generate electricity. When discussing this characteristic, it should be recalled that it is unacceptable to refuel a fuel tank in working condition. If you spill a little oil or gasoline, the risk of fire becomes too high.

In those situations where the need for long-term continuous operation of the power plant is very high, it is recommended to install an additional or reserve fuel tank. But here it should be taken into account 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 change is 50 hours. If the gasoline inverter generator is operated only once or twice a week, and only for 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 followed. 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 choose the oil. And a filter should be attached to the reserve fuel tank, which will separate water and impurities from gasoline.

Transition from 220 to 380 V

When choosing a gasoline inverter generator for a country house or production with single-phase consumption, a single-phase power plant should be preferred. True, based on the fact that their power is limited to 30 kW, this may not be enough.

If there is equipment that requires a three-phase current, then you need to buy an appropriate power station, but in order to even out the load, you need to divide the power into three lines. This is very important because three-phase generators are highly sensitive to phase imbalances. But if the power consumption of the equipment is small, then it is better to give preference to a single-phase station that has a system that combines the phases. Then the generator will operate in 220 V mode, and, if necessary, will go to 380 V mode.
