3 TECHNICAL INFORMATION
3.1
EXPLANATION OF FUNCTIONAL PARTS
The WhisperPower two and three cylinder Genverters are highly
advanced systems. They combine new technologies from various
fields such as engine technology, PM alternator technology and,
in the PowerCubes and Power Modules, inverter technology.
3.1.1
Control system
The engine is monitored and controlled by microprocessors in
the Digital Diesel Control system (DDC). The standard electrical
engine control system is 12 Volt negative earth. Non-earth return
(ungrounded) is available as option. Check your identification
data to determine which system is being used. Either system is
of the "energize to run" type: it stops when the 12 V DC voltage
is taken away. Highly advanced, the DDC controls the engine and
also operates as a management system to control the engine in
combination with the PowerCube.
3.1.2
AC Permanent Magnet Alternator
The Three Phase Permanent Magnet Alternator is incorporated
in the flywheel and has a very high efficiency of at least 94%. The
output of the power from the alternator will be between 250V-
300Hz and 400V-500Hz, depending on the engine speed. As the
efficiency is very high, little cooling is needed. The alternator and
the engine use the same cooling system.
3.1.3
Engine
The Genverter has a Kubota engine fine-tuned by WhisperPower.
The engine has indirect injection and was designed to meet the
highest emission standards. The cooling system can be used for
CHP (Combined Heat and Power production). Contact
WhisperPower for additional information.
Further details are in the data sheet in 3.2.
3.1.4
Starter battery charging
The engine is equipped with a 12.5A (two-cylinder version) or
40A (three-cylinder version) alternator for charging the starter
battery. The voltage is regulated at ±14.4V.
3.1.5
Alarms and shut-down
In the event of malfunctioning this will be indicated by the failure
light, details will be shown on the display and the engine will be
shut down. Two parameters are being monitored: oil pressure
and oil temperature.
All alarm switches are closed when no malfunction occur. A
contact is cut in the event of an alarm. This means that the
Genverter will not work when the alarm switches are broken or
when there is a loose wire. The system therefore is intrinsically
safe. The panel will display details about the alarm.
3.1.6
Control
The Genverter can be operated by push buttons on the panel on
the unit or on the remote control. Pushing the START button will
activate the control system and will start the engine
automatically. Pushing the STOP button will stop the engine and
the electrical system will be deactivated. When using the
Genverter in an automatic mode the engine will start when
power is demanded, e.g. because of low batteries or another

"event" that triggers the starting operation. Various automatic
modes are available through the remote control panel. Refer to
the DDC Operating manual for more information.

3.1.7
Remote control panel
The remote control panel is used to make the various settings. It
also displays parameters such as Voltage, Hz, Amps, and many
others (refer to the DDC manual for details).
The connection between the remote control panel and the
Genverter control unit is made using plug-in connectors. A 10 m
communication cable is in the standard supply. If necessary, a
longer or shorter cable can be supplied. Multiple remote control
units can be put in parallel by using the connectors on the back
of the units (refer to installation instructions).
