The little power house
The WhisperPower Genverter© Piccolo 4 is the smallest, quietest and most powerful of its kind. Thanks to the electronic PMG inverter output, it delivers the ideal power quality for all your comfort equipment such as a washing machine, small air conditioning system, electrical cooking hob, battery chargers and inverter/charger combinations.
All Piccolo 4 models are fitted with a modern diesel engine designed by WhisperPower, entirely for the purpose of generating power the smooth way. The engine is cooled by a heat exchanger designed for indirect water-cooling. The circulation water pump is driven by a PTO (no belt). This WhisperPower engine operates between 2400 and 3600 rpm.

Unique Genverter Technology
The Piccolo generator is a combination of a diesel engine with integrated alternator and an inverter, hence the name Genverter. Key feature of this technology is the quality of the output combined with the surge power capability. Within a certain window of the rotating speed of the diesel engine, the PMG delivers the correct power quality to operate comfort equipment, such as washing machines, air-conditioning, electrical cooking devices and various other AC appliances.
Ready to install
The Piccolo 4 diesel generator comes complete with all the fittings needed to connect the generator to the fuel tank, hoses needed to connect the engine to the cooling system, cables to connect the starter engine to the starter battery and electrical wiring to connect the Piccolo to the 120 V on-board power system.

Why inverter technology
Devices such as air conditioning units and electric motors are often controlled by electronics to improve the efficiency and performance. Traditional generators may fail to operate these appliances. All Piccolo models are equipped with a PMG module (Power Module Genverter©) to ensure that the voltage and frequency within the rotating speed range remain perfect so that all the equipment continues to run without interruption. Surge power is generated by the PMG to start up inductive loads.

“After replacing two other generators in my previous boat, I’m delighted with the variable speed nature of the Piccolo 4 installed in my new Arcona 465 Carbon. Because it’s been paired with a lithium battery system, I can constantly keep my air conditioning on and only start the generator when I need to charge. Weight is also significant since I use the boat for long-distance offshore racing.”
“The Piccolo efficiently delivers 3.5 kW and only weighs 150 lbs. The noise and vibrations are minimal too. I’m very pleased all around.”

Quiet & vibration free
Vibrations are just as irritating as an over noisy diesel engine. The customized shock mounts, combined with the sound enclosure, result in a super silent and virtually vibration free set-up. All parts needed to be serviced are located at one side of the Genverter. The effective engine mounting inside the enclosure result in a audible noise level of less than 55 dBA and virtually no vibration
