manual, and that he/she should carefully follow the instructions
contained herein. Both safety and durability depend very much
on the correct identification, installation and the correct
understanding of ratings, features, design, maintenance and
operation procedures.
The information, specifications, illustrations and statements
contained within this publication are given with our best
intentions and are believed to be correct at the time of going to
press.
All of the specifications, provisions and instructions contained
in this manual apply solely to standard versions of the standard
versions of the two and three cylinder genverters delivered by
WhisperPower.
This manual is valid for the following models:
For other models, especially Mitsubishi-based M-GV/2 and M-
GV/3 genverters, see other manuals available on our website:
www.whisperpower.com.
Our policy is one of continued development and we reserve the
right to amend any technical information without prior notice.
Whilst every effort is made to ensure the accuracy of the
particulars contained within this publication neither the
manufacturer nor the distributor or dealer in any circumstances
shall be held liable for any inaccuracy or for the consequences
thereof.
1.2 SERVICE AND MAINTENANCE
Regular service and maintenance should be carried out
according to the directions in this manual. For service and
maintenance, turn to the manufacturer or a dealer.
1.3 GUARANTEE
WhisperPower guarantees that this genverter has been built
according to the principles of good workmanship, according to
the specifications in this manual and according to European
Community safety regulations.
During production and prior to delivery, all of our genverters
are tested and inspected.
This genvertercorrect operation is subject to guarantee. The
period and conditions of this guarantee are laid down in the
general conditions of delivery as registered with the Chamber
of Commerce and Industries for the North of the Netherlands
number 01120025 and are available on request. The guarantee
period is two years, limited to 1000 running hours. Some
aspects of our guarantee scheme are given here in more detail.
Guarantee does not cover failures caused by misuse, neglect or
faulty installation.
Example 1: Faulty installation
Seawater entering the engine is the most common cause of
damage to combustion engines (both propulsion and generator
engines) in boats. The entry of water must be avoided under all
conditions. Be aware that the conditions in blue water sailing
can be extreme. Refer to the installation manual for
instructions but remember these are for guidance only as many
factors influence the installation of the genverter. The ultimate
responsibility will always be with the owner. If in doubt, ask!
Example 2: Misuse
Long term running with no load or too little load can cause the
exhaust to get choked with soot or carbon. Cleaning the
exhaust is not covered by guarantee.
Example 3: Neglect
Sometimes the seal of the raw water pump starts leaking.
Mostly this begins with a little drip and it slowly gets worse.
Regular visual inspection of the genverter is necessary to
prevent damage from occurring due to a leaking water pump.
When serious damage is discovered after weeks of neglect,
guarantee claims will not be honoured.
Example 4: Neglect
A WhisperPower genverter has an option for an auto start/stop
mode or interval mode. WhisperPower cannot be held
responsible for damage caused by the genverter running
unattended. Oil changes must be carried out according to the
maintenance schedule.
Guarantee means that faulty parts are repaired or replaced free
of charge. If necessary the whole genverter unit will be
exchanged. Labour necessary to complete repairs on board a
vessel by an authorized service engineer is covered, but is
limited to a reasonable number of hours and reasonable rates
in relation to the actual repair work that has to be done.
Travel expenses and travel hours are not covered, neither is the
labour required to take a genverter out of a vessel or for
reinstallation. There is no cover for labour needed to get access
Part no.

1.4 LIABILITY
WhisperPower does not accept responsibility for damage,
injuries or casualties which are the result of operation of the
genverter in specific conditions bringing dangers which could
not be foreseen, or could be avoided by additional measures.
WhisperPower does not accept liability for damage due to use
of the genverter, possible errors in the manuals and the results
thereof.
Automatic start/stop: WhisperPower cannot be

1.5 IDENTIFICATION
1.5.1 General
Before using this genverter it is very important to identify the
model correctly. To communicate for service or ordering parts it
is also essential to correctly identify the genverter. For the daily
operation of the genverter it is necessary that the operator
knows the correct specifications as well.
1.5.2 Identification plate
All required identification data are on the identification plate.
The identification plate also mentions some basic features of
the genverter.
SERIAL NUMBER: The identity of the genverter is given by the
serial number. Using this number, the manufacturer can trace
the specifications of the genverter.
POWER: The identification plate gives the maximum load in kW,
i.e. kVA calculated with power factor one. When calculating a
load one should always take into account the power factor or
cos phi of this load. The resulting load should not exceed the
nominal power as shown on the identification plate. Power is
rated at an ambient temperature of 25°C. For higher
temperatures the genverter has to be de-rated.
Figure 1: Identification plate
VOLTAGE: The Permanent Magnet Alternator (PMA) generates
a variable voltage between 250V and 400V. Depending on the
type of installation, this is converted by a DC PowerCube or an
AC Power Module for Genverter
FREQUENCY: The Permanent Magnet Alternator output
frequency is considerably higher than in in common alternating
current installation. The DC PowerCube and WP-PMG (Power
Module for Genverter), however, are designed to generate very
stable DC and AC outputs from the PMA output.
CURRENT: The maximum allowed current at the specified
voltage and power factor.
PHASE: The number of live wires running from the genverter.
WEIGHT: The net dry weight (approximately) in kg. This is
without fuel, oil, cooling liquid, packaging and external
installation equipment.
CE-MARKING: that the genverter is built
according to European Community safety regulations. This
includes the regulations regarding safety of pleasure craft,
electric safety and electric magnetic compatibility (EMC) and
other relevant directives. Under the Machinery Directive, the
genverter is an incomplete machine and can only comply after
installation; refer to the Declaration included in this manual.
Safety is also a matter of installation, utilization and operating
conditions. See also 2.1.
It is recommended to consult the manufacturer before
changing a factory setting. If the genverter involved is not new,
former users may have changed the settings. Check the settings
when there is any doubt.

2.1.4 Maintenance & repair
WARNING
When service has to be carried out while the
engine is running, be aware of moving parts.
If the genverter is switched off during
maintenance and/or repair activities, it should be
secured against unexpected and unintentional
switching on:
remove the DDC fuse from the local control
panel
remove the connections to the batteries
be sure that third parties cannot reverse the
measures taken.
Use original spare parts only. Always consult the manual before
carrying out maintenance.
2.1.5 Electrical safety
Warning signs indicate parts which could be live.
The alternator output (which is the inverter
input) can be as high as 400 Volt and is very
dangerous. The only way to get access to the high
voltage parts is with the help of tools. Never run
the genverter when there is access to these
parts. Touching these parts may result in
electrical shock which will result in severe
personal injury or loss of life.
Check all wiring at least once a year. Defects, such as loose
connections, burned cables, etc. must be repaired
immediately.
Do not work on the electrical system if it is still connected
to a current source. Only allow changes to your electrical
system to be made by qualified electricians.
Connections and protection must comply with local
standards.
2.1.6 Installation
WhisperPower genverters are not self-contained and have to be
properly installed. Installation involves proper ventilation, safe
electric connections, safe installation of the starting battery,
proper fitting of the cooling system and fuel pipes etc. In
enclosed areas, installation includes taking measures to outlet
exhaust fumes. Containing carbon monoxide, these are
extremely dangerous. Carbon monoxide (CO) is an invisible and
odourless gas. Inhalation produces headache, nausea or death.
Refer to the installation manual.
Do not use the genverter when the vessel is
inside a boat house or in other enclosed areas.
2.1.7 Operation
WhisperPower genverters have no external moving parts like
fans and V-belts. The fan of the radiator unit is covered by a
grid. The hot parts of the engine are covered by the sound
shield and therefore these genverters are very safe when the
sound shield is closed.
Nevertheless take note of the triangular signs on
the genverter indicating danger.
The genverter should be operated by authorized personnel
only.

GENERAL INFORMATION
M-GV/2, M-GV/3, M-GV/3+, M-GV 8, M-GV 10, M-GV 12 and M-GV 15  May 2018  EN 7
Be aware of hot parts and especially parts of the exhaust
system and the cooling system.
If the genverter is unsafe, fit danger notices and
disconnect the battery positive (+) lead so that it cannot be
started until the condition is corrected.
Do not attempt to operate the genverter with a known
unsafe condition. Disconnect the battery positive (+) lead
prior to attempting any repairs or cleaning inside the
enclosure.
Always consult the manual before carrying out
maintenance.
Do not change the settings without consulting the
manufacturer. Keep a record of setting changes in this
manual.
2.1.8 Fire and explosion
Fuels can be flammable. Proper handling limits
the risk of fire and explosion.
WARNING
Never use the Genverter in situations where
there is danger of gas or dust explosion or where
potentially flammable products are present!
Avoid refilling the fuel tank while the engine is running.
When oil or fuel is leaking do not use the Genverter.
Hydrogen gas generated by charging batteries is explosive.
Ensure proper ventilation. Do not smoke and do not allow
sparks, flames, or other sources of ignition around
batteries.
Keep a fire extinguisher on hand.
In case of fire, do not open the sound shield. To avoid
serious injury or death from fire, shut down engines,
generator sets and blowers. However, if you do open the
sound shield, immediately discharge the entire contents of
a portable fire extinguisher into the enclosure.
Poor electrical connections or using wiring which is not
suited for the rated currents can cause overheating and
possibly fire.
2.1.9 Dangerous substances
Fuels, oils, coolants, and battery electrolyte can be hazardous
to personnel if not handled properly. Do not swallow or have
skin contact with these liquids. Do not wear clothing that has
been contaminated by fuel or lubricating oil.
The gaskets used in the Genverter are free of asbestos.
However, gaskets containing asbestos can still be found. Avoid
inhaling particles of this material as this may result in fatal
diseases. Therefore it is a good habit to be careful with gaskets.
On no account allow 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 abnormally high
temperatures in excess of 315°C an extremely corrosive acid is
produced which cannot be removed from the skin. If signs of
decomposition of the material are evident, or if in doubt,
always wear heavy duty disposable gloves.
2.1.10 Warning regarding life support applications
The WhisperPower two and three cylinder Genverters are not
intended to be used as a component of any life support system
unless a specific written agreement pertaining to such intended
use is executed between the manufacturer and WhisperPower.
Such agreement will require the medical equipment
manufacturer either to contract additional reliability testing of
the Genverter and/or to commit to undertake such testing as a
part of the manufacturing process. In addition the medical
equipment manufacturer must agree to indemnify and not hold
WhisperPower responsible for any claims arising from the use
of the Genverter in the life support equipment.
2.2 TRANSPORT, LIFTING AND STORAGE
When lifting the Genverter avoid any risk of
personal injuries. In particular, do not stand
under the Genverter.
Use soft slings to avoid damage
The engine has a lifting eye which can be used to take the
Genverter out of the enclosure. It can also be used to lift
the complete Genverter including the enclosure.
After transporting the Genverter check for damage before
installation.
Long term storage can have detrimental effects on engine
and alternator. The engine should undergo an engine
preservation procedure (refer to the maintenance
chapter.)
Condensation may occur on alternator windings. To
minimize condensation, store the Genverter in a dry and
warm storage area.
While the battery is stored it should be recharged every 12
weeks.
2.3 FEATURES
2.3.1 General
The WhisperPower two and three cylinder genverters combine
2 and 3 cylinder engines with highly efficient Permanent
Magnet alternators. The voltages and frequencies produced,
however, require the genverter to be connected to a
WhisperPower DC PowerCube or Power Module producing
clean DC or AC output. This is an original concept, which is cost-
effective as wells as easy on installation.
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 enclosure. The output of the power from the
alternator will be between 300V-400Hz and 400V-500Hz,
depending on the engine speed. The engine speed is set to
strike a balance between fuel efficiency and comfort. All cables
and hoses are guided through the enclosure
