Comparison Hyundai HHY10050FE vs Konner&Sohnen KS 10000E G

The type of fuel that the generator's engine runs on.

— Gasoline. One of the main types of fuel for internal combustion engines. Gasoline generators are usually cheaper than diesel generators, all other things being equal, but they are more expensive to run due to the higher price of gasoline; in addition, they usually have a shorter resource than diesel ones. Therefore, it is believed that gasoline generators are well suited primarily as a backup power source in case of a power outage.

— Diesel. Diesel generators are usually more expensive than their gasoline counterparts; on the other hand, diesel fuel is cheaper than gasoline, so the increased cost may well pay off with regular use. In addition, diesel generators have a longer resource and a larger power range than gasoline ones. This allows them to be used as both backup and main power sources, including at rather "energy-intensive" objects.

— Gas. The advantages of gas-fired generators are relatively low noise levels and low emissions. On the other hand, the use of gas as a fuel is associated with certain difficulties: it is necessary to connect to a gas pipeline or regularly replace special cylinders, the fuel system is especially sensitive to leaks, etc. Therefore, there are relatively few such models produced, and most of them are stationary high power generators, in which the mentioned disa...dvantages are covered by the advantages.

- Gasoline / gas. Models capable of using both types of fuel indicated. This gives the user the opportunity to choose the option that best suits a particular situation, and also reduces the likelihood of being left without fuel at the most inopportune moment; on the other hand, such models are more expensive than single-fuel ones. The technical features of gasoline and gas are described in detail above.

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.

The operating power of the engine installed in the generator. Traditionally stated in horsepower; 1 HP approximately equal to 735 watts.

First of all, the rated power of the generator directly depends on this indicator (see above): in principle, it cannot be higher than the engine power, moreover, part of the engine power is spent on heat, friction and other losses. And the smaller the difference between these capacities, the higher the efficiency of the generator and the more economical it is. However high efficiency affects the cost, but this difference can pay off with regular use due to fuel savings.

Fuel consumption of a petrol or diesel generator when operating at half power, and for combined models when using petrol (see “Fuel”).

Fuel consumption usually increases with load. However, generator efficiency is not always linear - fuel consumption may vary disproportionately with different loads. In this case, the approximate amount of fuel consumed by the generator when operating at half power (50% of the rated power) is given. Knowing the fuel consumption and tank capacity, you can at least estimate how long one fill-up will last.

The noise level produced by the generator when operating in normal mode. 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. Thus, even the "quietest" units produce < 70 dB - this is the volume of a 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 the power: for example, among units of 80 dB and more, there are both heavy and relatively low-power models.

The total weight of the unit - usually excluding fuel; the weight on full tank can be easily determined knowing the tank capacity.

In general, more powerful generators are inevitably heavier, but models with similar characteristics can differ significantly in weight. When assessing these differences and generally choosing an option based on weight, it is worth considering the specifics of the generator's use. So, if the device is often to 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 special attention to this parameter - or even the opposite: choose a heavier (and, as a rule, more advanced and functional) option.

Regarding specific figures, it is worth noting that modern generators are generally quite massive. Thus, a small weight for such equipment is considered not only < 20 kg, but even 20-30 kg ; many units weigh 150-200 kg, or even more, and the weight of stationary industrial models is measured in tons.
