Inverter generator 7HP 3,5KW

Professional inverter power generator equipped with a combustion engine with a capacity of 212cc and a power of 7 HP. The generator's alternator has copper windings, allowing it to generate momentary maximum power of 3500W. The continuous power that the generator can handle is 3200W for one 230V socket, in case of using two sockets, the output power is divided between the two sockets.

Inverter generators operate on slightly different principles than traditional frame generators. The main and most significant difference is a much more advanced technology, known as a smoothed sine wave. One of the most important components of the generator is the inverter converter; it is responsible for initiating the production of high-quality, clean electricity, which is then converted into direct current in subsequent stages. It is thanks to the inverter and automatic voltage regulation (AVR) that it performs exceptionally well when powering devices sensitive to voltage changes. The fuel tank with a capacity of 12 liters allows uninterrupted operation (at half load) for about 9 hours.

Product Characteristics:

• Constructed using high-quality components and materials


• The inverter converter, in combination with a high-quality automatic voltage regulator (AVR), maintains a constant voltage, allowing the generator to be used as an emergency power source for all household appliances, even those sensitive to minor voltage changes such as computers, televisions, refrigerators, stoves, lighting, etc.


• A 7 HP engine allows for a maximum power output of 3500W and a continuous power of 3200W


• The alternator has copper windings


• At half load, the device can operate for 9 hours on a single fuel tank


• 2 x 230V sockets


• Manual start assisted by an electronic ignition system


• The device operates quietly, thanks to a properly selected muffler and very good damping (96 dB)


• The 12-liter fuel tank is equipped with a fuel level indicator
