4.4 kVA Generator

Where to buy
Website Header Marine
Silent, compact & light weight

Based on an indirect water-cooled diesel engine, fits into any space

Adjustable or variable speed

Up to 4.4 kVA (3.5 kW), 230 VAC, 1 ph, 50 Hz (60Hz)

Premium inverter technology

Highest output quality & strong peak power

The little power house

The WhisperPower 4.4 kVA generator is the smallest, quietest and most powerful in its class. Thanks to the electronic PMG inverter output, it provides ideal power quality for all comfort appliances such as washing machines, small air conditioners, electrical cooking hob, battery chargers and inverter/charger combinations.

Unique engine
Our marine 4.4 kVA generator is equipped with a modern diesel engine developed by WhisperPower to generate electricity smoothly. The engine is cooled by a heat exchanger designed for indirect water cooling. The circulating water pump is driven by a PTO (no belt). This WhisperPower engine runs between 2400 and 3600 rpm.

Unique Genverter Technology

Our 4.4 kVA generator is a combination of a diesel engine with integrated alternator and inverter, therefore the name Genverter. The main feature of this technology is the combination of output quality and surge power capability. Within a specific window of the rotating speed of the diesel engine, PMG provides the right quality of power to run electrical equipment such as tools, compressors, washing machines, air conditioners, electric cooking devices and various other AC equipment.

Ready to install
Our 4.4 kVA generator comes with all the fittings needed to connect the generator to the fuel tank, hoses to connect the engine to the cooling system, cables to connect the starter engine to the starter battery and wires to connect the generator to the 230 V on-board power system. Learn more about the Piccolo via WhisperTV.

Why inverter technology

Equipment such as air conditioners and electric motors are often controlled electronically to improve efficiency and performance. Conventional generators may not be able to operate these appliances. Our 4.4 kVA generator model is equipped with a PMG module (Power Module Genverter©) to ensure that voltage and frequency are kept perfectly within the rotating speed range to keep everything running without interruption. The surge power is generated by the PMG to increase the inductive load.

Shareef Quote4

Shareef Sourour, Marina Yachts Dubai

“The last 3 years I have delivered more than 25 boats with a WhisperPower 4.4 kVA generator, to operate a 16,000 BTU and a 10,000 Dometic Airconditioning unit, fitted with a soft start. They all have worked perfectly until today and are still running”

“This is a great product, there is no equivalent generator product available in the market”

Vibration Free1

Quiet & vibration free

Vibration is just as annoying as an overly loud diesel engine. A combination of customized shock mounts and sound enclosure make for an ultra-quiet and virtually vibration free construction. All parts needed to be serviced are located on one side of the Genverter. Effective mounting of the engine within the enclosure result in an audible noise level of less than 55 dBA and virtually no vibration.
