Output voltage
Rated voltage at the generator output.
—
230 V(1 phase). Standard voltage of a regular household outlet. It is widely used in everyday life, and among specialized equipment there are many 230 V devices; the only exception is powerful equipment (mostly from 4 - 5 kW), for which this voltage is no longer enough. It is 230-volt generators that are worth paying attention to, in particular, for those who are looking for a device for emergency power supply to a residential premises or small office.
—
400 V(3 phases). Generators capable of delivering three-phase power at 400 V. This power is rarely used in everyday life, but it may be required for heavy equipment and other similar loads. Generators with a voltage of 400 V are generally more powerful, heavier, more expensive and more power-hungry than 230-V generators. Most of them are equipped not only with three-phase, but also with single-phase sockets; however, it is worth specifically looking for such a unit only if the presence of three-phase power is essential.
Sockets 230 V
The number of 230 V sockets provided in the design of the generator, as well as the type of connectors used in such sockets.
The type of connector in this case is indicated by the maximum current that is allowed for the outlet — for example, "2 pcs at 16 A". The most popular options for 220-volt outlets are
16 A,
32 A and 63 A. We emphasize that the amperes in this designation are not the actual current that the generator can produce, but the outlet's own limitation; the actual value of the current strength is usually noticeably lower. Simply put, if, for example, the generator has a 32 A socket, the output current on it will not reach 32 A; and the specific number of amperes will depend on the rated and maximum power of the unit (see above). So, if for our example we take a rated power of 5 kW and a maximum of 6 kW, then such a generator can deliver less than 5 kW / 230 V = 22.7 A nominally and 6 kW / 230 V = 27 to a 230 V socket, 3 And at the peak. And if the power has to be divided between several outlets, then it, accordingly, will be even less.
As for specific types of connectors, the higher the current allowed for the outlet, the higher the requirements for its reliability and quality of protection. Thus, usually, smaller power plugs can be connected to higher power sockets (directly or through an adapter), but not vice versa. And if there are several sockets, by their type it is pos
...sible to estimate with a certain certainty the distribution of the entire power of the generator between them: between two identical sockets, this power is usually divided equally, and more power is allocated to the socket for a larger number of amperes. However, specific details on this matter should be clarified in each case separately; also consider 400 V sockets, if available (see below).Sockets 400 V

The type of connector in this case is indicated by the maximum power that is allowed for the socket - for example, "2 pcs for 16 A". The most popular options for 400V include
16A and
32A, although other socket types are also found. We emphasize that the amperes in this designation are not the actual power that the generator can produce, but the outlet's own limitation; the actual value of the power strength is usually noticeably lower. Simply put, if, for example, the generator has a 32 A socket, the output power on it will not reach 32 A; and the specific number of amperes will depend on the rated and maximum power of the unit (see above). So, if for our example we take a rated power of 7 kW and a maximum of 8 kW, then such a generator can give out no more than 7 kW / 400 V = 18.42 A nominally and 8 kW / 230 V = 21 to a 400 V socket, 05 And at the peak. In practice, these values will be even less, since three-phase devices are almost always supplemented with single-phase sockets, and the power will have to be divided between different types of sockets. The specifics of power distribution in each case should be clarified separately.
As for specific types of connectors, the higher the power allowed for the outlet, the higher the requirements for its reliability an
