WhisperPower ‘one stop shop’ is unique: the company is able to supply generator systems with all the necessary installation parts. No more shopping around needed.

Generators (programmable rpm)

WhisperPower's Genverter© combines the latest diesel engine technology with a new way of producing electrical power. Instead of adding an alternator with fixed speed on the back of the fly-wheel, the company has designed a very compact permanent magnet alternator (PM), located just behind the engine. As a result, these systems are much smaller and lighter compared to traditional generators. Customer benefits: • The output voltage of the generator is not dependent on the RPM (revolutions per minute) of the generator. The generator RPM can be fixed to a position offering the optimal balance between RPM, output power, audible noise and vibration. In most cases the result is 2300 RPM. • The PM alternator utilizes the same cooling circuit as the main engine making the installation much more simple. • The output voltage / power of the PM can be used for various purposes including integration into DC systems. For example with WhisperPower's DC PowerCube concept or as an inverter based variable speed generator, the Basic range. • WhisperPower's Genverter ‘I’ versions are HYBRID generators: variable speed just as with the Basic version, but with an additional inverter / battery charger, the WPC Power Centre, capable of providing sine wave AC power to the various on board appliances. The battery is automatically charged by the WPC’s Power Centre.

Sinewave inverter / charger

When inverters are combined in one box together with a battery charger, and a shore - to - inverter transfer relay, then the term Combi’s is used. The WhisperPower’s combi's are compact, space saving, robust and extremely powerful. Three different versions are available: • Supreme Combi (light weight, switch-mode technology) • WP-Combi (with high surge and high efficient toroidal transformers) • WPC PowerCentre ‘system combi’. Our most advanced unit with multiple input / output, high peak power capabilty, power support mode and UPS function

Battery Chargers

The main function of a battery charger is to charge the battery when the charger is connected to shore power. WhisperPower’s battery chargers convert any AC voltage or frequency to a smooth 12, 24 or 48 VDC voltage. Using WhisperPower’s battery chargers ensure a FAST and COMPLETE charge of the battery. As a result, the life time of the battery is much longer. The company's range consists of low power HANDY series, the multiple output SUPREME series and our heavy duty, high output DC POWERCUBE series. WP Handy The WP Handy range is suitable for recreational and semi-professional use. Easy to install, it includes a detailed display and easy battery type programmer.

This range, designed for hard wiring, is available in two variations.

Sine wave inverters

WhisperPower’s sine wave inverters convert a 12 or 24 V battery voltage into high quality house hold electricity. Low power appliances such as vaccuum cleaners, computers, chargers for phones and tablets do not require a diesel or gasoline generator but can be operated by an inverter instead. On an inverter, any 230V / 50 Hz appliance can be used at any time, without the need of a running engine. WhisperPower inverters are often used in combination with DC BeltPower alternators, connected to the main engine. WhisperPower offers two variants: • WP-Sine series, these inverters are available in 400W, 1000W and 2000W (12VDC or 24VDC) • AC PowerCube, these high-power inverters are available in 7000W and 14000W (24VDC or 48VDC)

Isolation transformers

WhisperPower offers the WP-GI isolation transformer, for 2 purposes: • to protect the 120V or 230V AC-environment in mobile applications • in marine applications to protect the ship against galvanic corrosion which can damage or even destroy underwater metal parts of a boat and other metal parts in a marina. WhisperPower offers the WP-GI isolation transformer, which minimize galvanic corrosion of the vessel.

Isolation blockers

WhisperPower offers the WP-GI isolation blockers, for 2 purposes: • to protect the 120V or 230V AC-environment in mobile applications • in marine applications to protect the ship against galvanic corrosion which can damage or even destroy underwater metal parts of a boat and other metal parts in a marina.

The company's digital WP Logic network, based on CAN-Bus technology (SAE J 1939), can be supplied as a complete ‘Domotica’ digital switching system. The traditional analogue WhisperSwitch systems include automatic switching between various power sources and automatic circuit breakers. The following variants are available: • Whisper Switch • AC Transfer System Switch • Earth leakage protection

Batteries

Batteries are increasingly becoming the centre of independent power systems, whether it’s for vessels, vehicles or remote land based locations. Batteries are used in hybrid systems in cars and vessels, in combined fossil and renewable systems combining for example wind and solar power sources or for emergency backup systems. Batteries are the key to a better energy balance in any system, a key to lower operational costs and reduction of emissions. In a WhisperPower system the battery has a central role: it is the energy tank, dictating when power sources (battery charging devices) should start to refill “the tank”. The selection of the right battery capacity and technology determines the functionality and durability of such systems. WhisperPower has built up its expertise in this field as a supplier of premium batteries over the past 20 years.

Battery monitoring

Batteries are an important component of a grid independent power or emergency back up system. Precise monitoring helps to look after the battery and optimise life span. WhisperPower offers a wide variety of battery monitoring systems, starting with the small WBM to the extended WP PSCP (Power System Control Panel), incorporating integrated generator controls. The main features of our monitoring range are: • WhisperPower provides monitoring for 12, 24 or 48 VDC batteries • WhisperPower offers pre-scaling sets to enable high DC system read-out • Shunts up to any Ah capacity can be ordered • For its inverter systems WhisperPower supplies the BSI-500 interface enabling read-out of the entire DC system including the consumption of the inverter

Battery isolators

WBL Battery Links The WBL Battery Links are devices that automatically connect two battery banks if the voltage rises above a pre-set charge value for at least five seconds, allowing these battery banks to be charged simultaneously. To protect the battery when the voltage drops, the battery banks are isolated once again. Two models are available: • 120A/ max 180A • 160A/ max 480A WBI Battery Isolators WhisperPower's WBI battery Isolators are designed to charge 2 or more individual batteries or battery banks from one power source: a battery charger or a DC alternator. The WBI is an ideal solution to charge separate battery banks, when the output voltage of a charge device cannot be adjusted to compensate for a voltage drop which occurs when an ordinary battery isolator is being used. The WBI keeps the voltage at the correct charge level. Two models are available: • WBI 150-2 • WBI 150-3

Battery switches

DC Battery Switches - Compact Series 300A Designed for battery banks of 12, 24 or 48 VDC, manually operated COMPACT series DC Switches are the best choice to connect or disconnect DC consumers from the relevant battery bank. DC Battery Switches - HD Series 600A Quality Products engineered for the harsh marine environment and built to last. Robust and compact design.

All relevant information about the generator system is clearly indicated on this high resolution 7" TFT widescreen (16:9) display with LED backlight and full vector graphic capabilities. Suitable for operation with conventional or CAN-bus based communication protocols

Shore Power Connections

When yachts, vessels and vehicles are connected to shore power, generators can be switched off. Onboard batteries, charged from shore power via the onboard battery chargers, transfer AC power directly to AC appliances. WhisperPower is the one stop shop for top class AC connection components. WhisperPower offers a ‘link’ to a comfortable and pleasant stay on board of a vehicle or vessel. When connected to the public grid, the shore power is the energy source for on board equipment including the batteries. WP-ShoreConnect is a waterproof inlet, mounted on the outside of the boat. WP-ShoreConnect offers the full range needed for a safe & reliable shore connection. The product design is based on the international IEC 60309 standard for outdoor connections.
