Inverter technology:
The generator produces electricity with constant frequency and voltage, thanks to an electronic converter that separates the input voltage from the output voltage. It uses a permanent magnet generator and regulates the engine speed according to the load, reducing consumption and noise, especially with medium-low loads. This system guarantees reliable power quality for sensitive equipment such as computers and medical instruments.

Silenced generator:
The silenced design makes the generator suitable for campsites, caravans, homes, flat buildings and other situations where noise-free electricity is required.

Main applications:
Ideal for powering sensitive electronic equipment, such as computers, medical devices and measuring instruments, which are sensitive to voltage and frequency fluctuations.

The generator is not designed to be incorporated into a photovoltaic or solar panel system for energy production, nor for recharging or maintaining batteries in such systems or other types of systems of any kind; such use may seriously damage the generator.

WARNING: all power generators such as this one, belonging to one of the lowest product levels of the PROFESSIONAL level (reference to the product level rating scale used on this website) must not be operated for more than 3-4 hours continuously, in order not to compromise the medium to long-term life of the alternator and other components due to overheating or wear. The same applies if the generator is used daily or frequently. In all these cases, we recommend choosing generators classified as at least PROFESSIONAL on the product level scale used on this website.

INDICATOR LIGHTS:

- RIGHT LIGHT : Oil warning system. Designed to prevent damage to the engine caused by insufficient oil. Before the oil level can drop below the safety limit, the red oil warning light comes on and the oil warning system will automatically shut down the engine. * Warning: the engine is supplied without oil

- CENTRE LIGHT: Power supply. Lights up after the power switch is turned on. Under normal conditions, only this green light should be on.

- LEFT LIGHT: Overload warning. If the generator is overloaded, or if there is a malfunction or short circuit in a connected appliance, this red overload warning light will come on. After a few seconds, the power supply will be interrupted and the green light will go out.
In this case, switch off the engine and find out the cause of the overload

The generator is equipped with a trolley and wheels for easy transport. It is also equipped with rubber feet for maximum stability.

As regards the power required for your intended use, here is a handy table to help you navigate between consumption, peak coefficients and watts.

The best criterion is to first identify the tools that need to be powered by the generator and then perform a simple calculation, as explained below, to determine the power that the generator must be able to deliver.

Power required = Consumption of the object X Peak load factor

The starting coefficient is a fundamental characteristic of any electrical device that indicates how much the consumption of the device increases during start-up and is therefore used to determine exactly how many WATTS are required to start it.

Example: Air compressor (1500 Watts) X Coefficient (2) = 3000 Watts Therefore, choose a generator with a power in WATTS equal to or greater than the result obtained (*)

Check the consumption of your appliance in the user and maintenance manual or on the label attached to it

PLEASE NOTE: the table is purely indicative. Using the above formula, you can easily calculate the power that a generator must deliver to connect and operate certain products and therefore identify the most appropriate model for your needs: And remember that in order to operate electronic equipment (computers, televisions and all equipment with an electronic board), you must purchase a power generator equipped with an 'inverter' (which stabilises the power output).

• This inverter generator is equipped with an ELECTRONIC BOARD to stabilise the current supplied, generating an almost perfect wave.
  This makes it particularly suitable for certain applications, but unsuitable for others.
  Some examples of FIELDS OF APPLICATION: power supply for all types of electronic equipment (as they are equipped with electronic boards and therefore require a very stable current to avoid the risk of damaging these boards), household appliances, kitchen and domestic equipment and appliances, lights and lamps; in conclusion, they are specifically designed for strictly domestic use, or for holiday and leisure use (in motorhomes, boats, etc.)

  Some examples of FIELDS OF NON-APPLICATION: construction equipment, workshop equipment, DIY equipment, welding machines, equipment of any kind equipped with brush motors (which, in case of brush wear, can cause power surges to return to the generator, which can damage the generator's electronic board); basically, for all of this list of equipment typically used for work, construction or crafts, an inverter generator is too delicate and therefore unsuitable. It is therefore necessary to opt for a classic generator, not with an inverter board, but equipped with a classic alternator with a heavy stator and rotor, which are more suitable for powering this equipment.

  Please also note that inverter generators are designed for NON-PROFESSIONAL use and are therefore only suitable for occasional (infrequent) use. Operating sessions should not exceed 3–4 hours continuously (which would cause the alternator to overheat or wear out). If you need a generator for frequent use (e.g. once a week), you should choose another type of generator specifically designed for frequent use, more precisely a PROFESSIONAL or, better still, INDUSTRIAL generator.

  The inverter generator is not designed to be connected to a photovoltaic or solar panel system for energy production, nor for charging or maintaining batteries for these systems or other types of systems of any other nature; this use may seriously damage the generator, both in the alternator, motor and electrical parts; all photovoltaic systems require a generator for INDUSTRIAL use (and not domestic use such as this one), specifically designed and manufactured for this purpose. NO WARRANTY IS PROVIDED on power generators used in a photovoltaic system, as this constitutes IMPROPER USE OF THE EQUIPMENT.
