Comparison Konner&Sohnen Basic KS 6000D vs Hyundai DHY6500L

Model name of the engine installed in the generator. Knowing this name, you can, if necessary, find detailed data on the engine and clarify how it meets your requirements. In addition, model data may be needed for some specific tasks, including maintenance and repair.

Note that modern generators are often equipped with branded engines from famous manufacturers: Honda, John Deere, Mitsubishi, Volvo, etc. Such engines are more expensive than similar units from little-known brands, but this is offset by higher quality and/or solid warranty conditions , and in many cases, the ease of finding spare parts and additional documentation (such as manuals for special maintenance and minor repairs).

The working volume of the engine in a gasoline or diesel generator (see "Fuel"). Theoretically, more volume usually means more power, but in fact, everything is not so clear. Firstly, the specific power strongly depends on the type of fuel, and in gasoline units, also on the type of internal combustion engine (see above). Secondly, similar engines of the same power can have different volumes, and there is a practical point here: with the same power, a larger engine consumes more fuel, but by itself it can cost less.

Fuel consumption of a gasoline or diesel generator, and for combined models — when using gasoline (see "Fuel").

A more powerful engine inevitably means more fuel consumption; however, models with the same engine power may differ in this indicator. In such cases, it is worth considering that a model with a lower flow rate usually costs more, but this difference can quickly pay off, especially with regular use. In addition, knowing the fuel consumption and tank volume, you can determine how long one refueling will last; at the same time, in inverter models at partial load, the actual operating time may be noticeably higher than the theoretical one, see "Alternator" for details.

The volume of the fuel tank installed in the generator.

Knowing the fuel consumption (see above) and the capacity of the tank, you can calculate the operating time on one gas station (if it is not indicated in the specifications). However, a more capacious tank is also more bulky. Therefore, manufacturers choose tanks based on the general level and "voracity" of the generator — in order to provide an acceptable operating time without a significant increase in size and weight. So in general, this parameter is more of a reference than practically significant.

As for the numbers, in low-power models, tanks are installed for 5 – 10 liters, or even less ; in heavy professional equipment, this figure can exceed 50 liters.

The time during which the generator is guaranteed to operate without interruption.

This parameter is indicated exclusively for liquid fuel models with a built-in tank, and according to the simplest formula: tank capacity divided by fuel consumption. However, in some models, data may be provided for a certain load level (which is specified in the notes); at a higher or lower load, the operating time will be shorter or longer, respectively. As for specific numbers, in most modern generators the operating time is up to 8 hours - this is quite enough for backup power and occasional use. More reputable models are capable of working for 8 – 12 hours, and an indicator of 13 hours and above is typical mainly for professional solutions.

We also note that, theoretically, many generators can be refueled without shutting down, but in practice it is better to take breaks and not exceed the stated time of continuous operation - this will avoid overheating and increased wear.

Existence in the generator of an output with a direct current and voltage of 12 V. The main function of this output is to charge car batteries, as well as power devices originally intended for cars (recall, 12 V is the standard voltage of on-board networks in cars).

The following types of 12-volt outputs are found in generators:

- Terminals. Terminals are used to connect wires directly without using any plugs. This connection is the most reliable.

- Socket. Socket outlet for a plug with two flat pins, designed to connect 12-volt consumers. Holes in sockets come in different layouts, which you need to pay attention to.

- Cigarette lighter. The so-called "car socket", which in many cars is combined with a cigarette lighter socket (hence the name). Such connectors are used to power various automotive devices and accessories.

The noise level produced by the generator during normal operation. The less noise the unit makes, the more comfortable it is to use, the closer it can be placed to people, but the higher its price, all other things being equal.

It is also worth considering that generators with internal combustion engines are, in principle, quite noisy equipment. So, even the “quiest” units produce up to 70 dB - this is the volume of conversation in tones from medium to high. Accordingly, it is recommended to install the device remotely from the place of use. At the same time, we note that the noise level is not directly related to power: for example, among units with 80 dB or more, there are both heavy and relatively low-power models.

Sound pressure level in decibels at a distance of 7 m between the noise source and the ear of the equipment operator. Since people do not work in the immediate vicinity of the generator, the parameter will be useful for estimating the noise level at a distance. For example, current European Union regulations require that the sound power of generating sets with a power of more than 2 kW does not exceed 97 dB — at a distance of 7 m, the noise from the generator engine will correspond to a sound pressure of about 72 dB.

The total weight of the unit - as a rule, excluding fuel; The full fill weight can be easily determined by knowing the tank capacity.

In general, more powerful generators inevitably turn out to be heavier, but models with similar characteristics can differ noticeably in weight. When assessing these differences and generally choosing an option based on weight, it is worth taking into account the specific application of the generator. So, if the device will often be moved from place to place - for example, when used “on the road” - it may be worth paying attention to lighter units that are more convenient to transport. However, it is worth considering that the downside of a lightweight design is often an increased cost or a reduced degree of protection. But for stationary use, you can not pay much attention to this parameter - or even the opposite: choose a heavier (and, as a rule, more advanced and functional) option.

Regarding specific numbers, it is worth noting that modern generators in general are quite massive. So, a small weight for such equipment is considered not only up to 20 kg, but even 20 – 30 kg ; Many units weigh 150–200 kg, or even more, and the weight of stationary industrial models is already measured in tons.
