There are three types of load : resistive, reactive and electronic.
Regardless of the type of load connected, a good quality electricity supply improves the performance and reliability of the connected equipment . In particular, electronic loads, if powered by poor quality generators, are subject to failures . To stabilize the output voltage and frequency, current generators can adopt three types of solutions: with Capacitor or Inductive type, with AVR card, and with Inverter.
It is the simplest and most popular solution in the field of industry. It is characterized by high reliability and is mainly suitable for resistive loads
Inverter generators provide high quality energy that is not dependent on the engine speed. The inverter generators allow the construction of compact generators with alternators of half the size compared to traditional systems and are ideal for powering highly sensitive and sophisticated electronic equipment . The inverter generators are able to supply high quality energy for both reactive and electronic loads and guarantee the best performance and maximum life of the appliances. Other benefits linked to the use of inverters are: reduced noise, lower weight and fuel savings.
It is an automatic voltage and frequency regulation device that minimizes fluctuations due to load variations. AVR technology significantly improves the performance and durability of reactive load equipment .
It is a Honda patented technology that, compared to the standard inverter system , uses a simplified system capable of providing higher quality electricity than systems with AVR cards. In fact, in this system the production of electricity is not directly linked to the engine speed.
Knowing the difference between kilowatts (kW) and kilo Volt Ampere (kVA) is useful to establish in greater detail the field of application of the current generator. To explain it in simple words, these are two units of measurement used to indicate:
In DC circuits the kVA are equal to kW since the voltage and current do not go out of phase. On the other hand, in AC circuits the voltage and current could be out of phase. This phase shift, called Power Factor or Cos-fi, depends on the type of load to be powered and tends more to 1 the more the load is of the resistive type (such as light bulbs, toasters, stoves, etc.). For reactive loads (electric motors, pressure washers, welders, etc.), on the other hand, the power factor can also assume values much lower than unity, such as 0.8, 0.7 or even 0.6 .
Assuming having to feed an active power of 10kW if the user is resistive, with a cos-fi power factor equal to 0.9, a 13kVA generator is more than sufficient as 13 * 0.9 = 11 , 7 kW margin of 1,7kW on the maximum power.
Assuming instead a 10kW user consisting of an electric motor or an industrial machinery that uses many electric motors with a power factor of 0.7, the 13 kVA generator will no longer be sufficient as 13 * 0.7 = 9.1kW. In this case, a current generator of at least 16 kVA will be needed as 16 * 0.7 = 11.2kW
calculate the necessary power, in addition to taking into account the cos-fi power factor of the type of equipment that will be powered, if the load is reactive, such as electric motors, you must pay attention to the inrush current of which need to boot.
For a simple and quick calculation of the power of the generating set required, the following formula can be used:
Power Required = P x K x 1.25

Diesel , petrol or gas generating sets , on the market there are generators for every type of fuel. Usually gasoline generators are the most used because they require less maintenance as well as being lighter and quieter . On the plus side, diesel generators have longevity lasting longer than petrol. Generally, diesel generators are chosen for high displacements and high electrical power required. The least common, and forever valid alternatives, are LPG or methane gas generators depending on the case.
Obviously, when the generator is to be used in "quiet" areas , where minimal noise pollution is required, the choice indicated is certainly directed towards silenced generators . Pay attention is the method of declaration of the producers that often and willingly can vary considerably.
Mainly some use the actual acoustic power at 1 meter away, others the acoustic power at 7 meters, and still others even at 7m with the generator at 70% load. It is therefore immediately clear that the declared values must be "taken with a grain of salt" .
Acoustic power is measured in dB , for reference here are some examples :
Inverse law of distance
Doubling the distance from a sound source the drop in dB is equal to 6 , halving the distance there is an increase in sound pressure of about 6 dB. In summary, moving away of another 7 meters from the generator, its noise drops by approximately 6dB .
Electric generators supplied complete with battery for electric starter with key for a quick, simple and comfortable start. Keep in mind that batteries to last over time must be kept charged periodically to ensure their duration over time. If you will use the generator once a year the batteries will not be a good choice for the life of the battery. Obviously all electric start generators, if only the semi-professional and professional ones, include recoil starters.
What is the ATS electrical panel. This is a switch that allows the power generator to start automatically in the event of a power failure. It is precisely a device for emergencies.
The differential switch, better known as "Salva Vita" is precisely a safety switch that automatically opens the circuit, interrupting the flow of electric current following its detection of any difference in electrical currents in input and output to the electrical system in case of leakage.
Almost all power generators over 50Kg can be supplied with a transport trolley. Some are equipped with small wheels included as standard (especially the silenced ones) or with a practical hook for cranes and lifters in general.
