W-GV4 Scalino outdoor — April 2017 — EN
Hydrogen gas possibly generated by batteries being
charged is explosive. Ensure proper ventilation. Do
not smoke or allow sparks, flames, or other sources of
ignition around batteries.
Keep a fire extinguisher on hand.
2.1.9
Chemicals
Fuels, oils, coolants, and battery electrolyte can be
hazardous if not treated properly. Do not swallow or
have skin contact with these liquids. Do not wear
clothing that has been contaminated by fuel or
lubricating oil.
On no account allow any unprotected skin to come
into contact with the injector spray as the fuel may
enter the blood stream with fatal results.
Engines may be fitted with seals or O-rings
manufactured from "Viton" or similar material. When
exposed to abnormal high temperatures in excess of
400°C an extremely corrosive acid is produced which
cannot be removed from the skin. If signs of
decomposition are evident, or if in doubt, always
wear disposable heavy duty gloves.
2.2
Transport, lifting and storage
When lifting the Genverter avoid any risk of personal injuries,
do not stand under the Genverter.
Use soft slings to avoid damage
On the engine is a lifting hoist eye which can be used
to take the Genverter out of the capsule. It can also
be used to lift the complete Genverter including the
capsule.
After transporting the Genverter check for damage
before installation.
Long term storage can have detrimental effects on
engine and alternator. The engine should be put
through an engine preservation procedure. (Refer to
the maintenance chapter).
The alternator windings tend to condense. To
minimize condensation, store the Genverter in a dry
and warm storage area.
Follow the battery manufacturer’s instructions when
storing the battery.

Features
2.3.1
General
The WhisperPower Genverter combines a small oil cooled
diesel engine, a Permanent Magnet alternator and an Inverter,
making variable speed possible. Variable speed means that the
engine will operate in a specific rpm window without affecting
the 50Hz/60Hz output frequency of the inverter.
The benefit is that the inverter is supplying a stable 230V and
50Hz or 60Hz output while the engine is running as efficiently as
possible. This result in smooth running, reduced vibration,
excellent combustion and substantial fuel savings.
The W-GV4 can be installed with an optional variable speed
control. A stepper motor is installed on the speed throttle of
the engine. The speed is regulated by a signal from the WP-
PMG.
When little power is needed the engine runs at low (2500) rpm,
speeding up to 3600 rpm when a high output is required.
Because of the variable speed the unit operates much more
economically (less fuel consumption). The life time is much
longer than for generators running constantly at high speed and
the noise level is much lower while running at low speed.
2.3.2
Construction
The Genverter incorporates a diesel engine which has a
permanent magnet alternator in the flywheel. The engine is
mounted on a steel base frame and mounted securely on a
double set of anti-vibration mounting pads in a sound
attenuated canopy. The output of the power from the
alternator will be from zero up to 3 phase 250V-400Hz and
400V-500Hz, depending on the engine speed. The separate
Power Module Genverter WP-PMG will invert this output to
230V/50Hz.
2.3.3
Engine Control Unit
The engine control unit incorporated in the Power Module
Genverter is based on microprocessor technology. For detailed
information of the engine control unit refer to the user’s
manual of the WP-PMG.
If DC output is required, the Genverter is installed in
conjunction with a DC PowerCube and engine control is
provided by an external digital diesel control box (DDC). This
takes care of engine operation monitoring and control (refer to
Digital Diesel Control user’s manual for DDC specifications and
possibilities).
The remote control panel including cable comes as standard
with the Genverter.
