Superior power systems
for recreational and commercial craft
air is needed for cooling, so the sets
can be stowed away in the smallest
of places. Almost all models are fitted
with an electronic governor which
results in an extremely stable output
voltage and frequency. All WhisperPower models are supplied with Digital
Diesel Controls (DDC) power system
management, offering easy to understand information on operational
status. Interfaces are available for bus connectivity including NMEA 2000.
WhisperPower is the leading European manufacturer
of “smart” power systems.
The comprehensive range of diesel generator systems, utilizing inverter
technology and advanced power management, has been used for over
15 years by many yacht builders, commercial shipbuilders, vehicle
manufacturers and various other markets throughout the world.
Six 1500 rpm models, three 3000 models and a new generation
of variable speed GENVERTER models coming up.
WhisperPower integrates marinized Mitsubshi and Kubota engines
to operate in the marine environment. For the one cylinder M-SC 3.5
a marinized industrial Kubota engine is used while the GENVERTER
one cylinder models operate with WhisperPower designed engines.
All standard WhisperPower products can be delivered immediately from
inventory and our flexible manufacturing techniques allow for a timely
fulfillment of customized units demands.
Main characteristics of WhisperPower systems:
Compact, electronically controlled, ease of operation. The systems are
supplied with metalic or polyester sound shield, ready to install, with all
connections pre-fabricated. WhisperPower exhaust kits, fuel kits, water
inlets kits and various other key installation components are supplied
as optional kits and are available from stock. The extended range of
generator sets includes models from 3.5 KW for basic comfort to 30 KW
“full comfort” power rating.
We make the product the way you want it:
• WhisperPower sets with dry exhaust. (for vessels operating in
shallow waters or inland waterways)
• WhisperPower sets with PTO (Power Take Off) for installation of
a hydraulic pump, mounted to the generator end to provide up
to 25KW of hydraulic power to operate hydraulic equipment.
• WhisperPower sets can be manufactured with isolated ground for use on aluminum vessels.
WhisperPower produces three main product series:
The Super Compact 3000 rpm range of diesel generators up to 10 KW,
the Super Quiet line of 1500 rpm sets from 5.7 kW up to 30 kW and the
new GENVERTER range of variable speed inverter integrated products.
The GV 4 Basic (3.8.kW) and 7i (7 kW) are now available for 230 V 50 Hz
output.
Technology used for the 3000 & 1500 RPM models: synchronous alternator technology, all single phase back ends are water cooled, hardly any
Complete installation kits
• We offer complete installation kits of the highest quality: non-flammable water exhaust separators and waterlocks (Delta exhaust parts/ ABYC compliant), rubber hoses, fuel kit with fuel/water separators, anti-siphon kits, starter battery kit, etc.
• We are able to supply our systems with specific certifications like Lloyds, GL or ABS.
• All our models are available for 60 Hz use as well.
