TECHNICAL INFORMATION
3.1
Parts and relevant functions
The W-GV4 Scalino Genverter is a very advanced high tech
variable speed power supply system. It combines new
technologies from various fields such as engine technology,
Permanent Magnet alternator technology and inverter
technology.
3.1.1
Engine
The engine used in the Genverter is developed by
WhisperPower and manufactured exclusively for
WhisperPower. The concept is unique as the engine is fully
cooled by oil. The same oil that is used for lubrication is also
used for cooling. However the lubrication circuit is separate
from the cooling circuit that has its own pump.
As the cylinder and cylinder head are surrounded by oil the
noise of the engine itself is extremely low. The oil cooling
makes it possible to apply the engine in an almost fully enclosed
canopy, what makes the Genverter even more silent. The oil is
cooled by a relatively small heat exchanger.
One could use the hot oil for generating heat (CHP Combined
Heat Power generation). For this application additional
information can be provided by WhisperPower.
Further details can be found in 3.2.
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 94% or higher
because of the very high tech super magnets that are used. 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
includes a fan that circulates air to cool the windings.
Further technical data on the design of the alternator can be
found in drawings and diagrams in this manual.
3.1.3
Engine Control Unit and DDC
Depending on the Scalino system, the engine control is either
incorporated in the WP-PMG or it is part of an optional DDC
control box.
3.1.3.1 WP-PMG Power Module Genverter
Through the WP-PMG Power Module Genverter, the user can
control and operate the GV4 Scalino.
Figure 1: WP-PMG control panel
By pushing the START button on the PMG control panel (refer
to Figure 1) for two seconds, the control system is activated and
will start the engine automatically. Pushing the STOP button
(again hold two seconds) will stop the engine and the electrical
system will be deactivated.
The PMG control panel also displays information such as output
voltage, AC load and engine diagnostics.
For remote control the WP-PMG Power Module Genverter is
supplied with a remote panel, which combines the start and
stop buttons into a single button. Its operation is basically the
same, though.

In addition, the WP-PMG incorporates an extended status
interface input/output module featuring enable/disable,
start/stop, fire shutdown and WhisperConnect CANbus for
advanced diagnostics. These features are explained in the WP-
PMG owner’s manual.
