6. Introduction WhisperPower
Founded July 2007 by Roel ter Heide, MD of Victron Energy (1983), founder of Mastervolt (1991), Mastervolt Gensets BV (1998). The Sun Factory (2000), and Hybrid Power Systems (2010).
WhisperPower is the spin - off from the Generator division of Mastervolt which was founded in 1998
14 Mio EUR sales in the first 18 months
Growth ambition: 20 Mio sales in 2015 6

7. Introduction WhisperPower
Over diesel generators sold since 1998
From 3 kVA – 25 kVA, low and high rpm
System approach – all installation components from one supplier
Various markets: marine, mobile, domestic, defence
Since 1st July direct involvement in global marine markets – Mastervolt stops selling fixed rpm gensets 7

8. Anticipating market trends
Over the past 20 years boat sizes increased
Electrical: From 12 V battery based systems to high kVA 230 V/50 Hz AC systems
Technical installations became more and more complicated in order to meet customer need for comfort: entertainment, comfort during mooring, anchorage and navigation
With size, boat prices increased substantially 8

9. Anticipating market trends
Power systems have grown in kW size over the years
Price/ performance /size / weight / audible noise level and “ silent time” critical
Interfacing of components with Bus systems
System design in such a way shore power can be used in an optimal way
Global infra structure to support the systems 9

10. Demand in the market is changing
Marine industry has challenges:
Boat owners have higher demand
More adequate service, higher quality, better infrastructure (marinas), more cost effective approach/ lower prices
Environmental: audible noise, emissions, exhaust gasses, soot, more efficient hull design, building materials must be durable, etc.
“ Making boating more fun” – but keeping new norms and values in mind 10

11. The new way of yachting experience
Yachts are used more and more as floating hotels
Owners want to navigate the vessel with family – preferably without crew
All comfort from home has to be available
Short and long range use
Systems have to work properly, silently and clean
We see new initiatives: navette style/ house boats, steel yachts for European waterways 11

12. “Blue hull, green soul”
Also in the Super Yacht industry: trends are Greener and Cleaner.
Hull design, building material wood FSC approved, low emission engines, exhaust filters for generators etc.
Latest launch: Azimut Magellano 50 Ft (Hull design by Bill Dixon, exterior Cor de Rover)
Less fuel consumption, optional Hybrid 2 x 50 kW propulsion, low emission main engines, etc. 12

13. WhisperPower’s contribution
We still need diesel power for propulsion and power – solar/ wind/ fuel cell power is not realistic now
We can improve the energy balance by using the generated energy in a better way
Our new Genverter/ GPX hybrid generator and our new Hybrid systems are good examples of how we can improve 13

14. More integration HYBRID GENERATOR (5 KVA) COMBINING:
Sine wave inverter (for silent AC power)
Shore “booster” – power support at low A
Diesel generator (VST = Variable speed)
Source selection: AC power/ Shore/ genset/inverter
Shore connection  battery charging 14

15. Hybrid Generator (5 kVA)
Sine wave inverter provides AC power from 24VDC, inverter power 2kW Continuous, 4kW peak
Permanent Magnet alternator integrated with fly wheel: compact and high efficient
Intelligent power management system controls: variable engine speed
Switch mode battery charger with 3-stage charge characteristic
1-Cylinder WhisperPower diesel engine 15

17. INNOVATIONS Variable Speed technology (VST)
Permanent magnet technology
Flywheel alternator
Power electronics /inverter technology
Microprocessor control and power management
Oil cooled engine
Energy storage: The SERVICE BATTERY is the key element of an on-board system. 17

18. Hybrid Generator Advantages
Lower fuel consumption
Lower CO2 emissions
Lower exhaust emissions
Silent mode
Lower noise when running
Shorter running time
Longer lifetime
High peak power
Smaller dimensions 18

19. Hybrid Generator (5 kVA)
Available in 2011 as Mastervolt GPX 5 kVA/ for global marine markets,
As GENVERTER 5i for global non-marine markets through WhisperPower distribution. 19

20. Hybrid Power and Propulsion
Further integration  cost effective reduction of components and longer “ silent” time with reduced generator running hours
Lower kVA rating of generator  batteries will provide surge power (peak shaving)
Variable periods of “silent navigation”
Battery operates vital functions: maneuvering, hydraulics etc.
More freedom of interior design
Less environmental pollution
Access to natural parks 20

31. ADVANTAGES OF THIS SYSTEM
Zero- emission navigation for several hours
No generator(s) needed during sailing
Over 16 hours of silent mode, no generators even when Aircon is on
Variable speed generator starts when batteries require recharge or high loads are switched on
Genverter generator will adapt RPM to load pattern – low noise level at low rpm
Regaining energy when sailing 31

32. Other system variations
Full hybrid (serial configuration)
Diesel- electric with battery mode
Optimal freedom when configuring the interior
Diesel (s) are used for propulsion AND power generation
Peak shaving  batteries 32

33. Capital investment for such systems
At least 2 x times traditional price level
But much smarter functionality  silent mode “ hotel periods” and zero emission navigation
Shore power amperage not a real issue / power support / peak shaving from the battery
Strong reduction of wear and tear/ maintenance costs
The real “Power of Green” 33
