USR generators are specially designed to be compact, quiet and powerful, saving up to 30% in weight and
space! They are ideal for superyacht owners looking for a nighttime generator with low operating sound
levels and vibrations. These generators are characterized by their fuel-efficient, innovative and environmentally
friendly inverter technology. Generators using parallel inverters can be paralleled and synchronized without any
additional cables.

The speed of the diesel engine is adjusted according to the user's changing power demands, while the output
voltage of the inverter remains constant at all times. Variable speed control greatly reduces exhaust emissions and fuel consumption compared to conventional fixed speed generators. The maximum engine speed is 3000 RPM. The electrical load is supplied with a constant output voltage of 230 V / 50 Hz or 400 V / 50 Hz via an inverter.
