Raffinesse auf See

Große Yachten bieten Luxus und Komfort jenseits der meisten Heime. Oder sogar Hotels. Sie werden sich in der voll ausgestatteten Küche wiederfinden, eine erstklassige Unterhaltungssuite genießen oder sich in einem anspruchsvollen Büro um das Geschäft kümmern. Victron verbindet das Niveau des Luxus mit modernster Energieausrüstung, die Ihnen monatelang volle Autonomie bietet.

Wie viel Energie benötigen Sie?

Nehmen wir an, Sie verbringen einen Teil des Jahres in Ihrem zweiten, schwebenden Zuhause. Die umfangreichen Vorräte an Bord bieten Ihnen die Freiheit, wochenlang vom Ufer weg zu bleiben und in Ihrer Lieblingsbucht zu ankern. Dank eines voll ausgestatteten Büros an Bord geht es wie gewohnt weiter, mit einer Aussicht, die nicht einmal Ihr Büro in Manhattan erreichen kann.

Was ist der Optimale Energieplan, der das alles möglich macht?

Verbrauch

Wie viel brauchen Sie?

Eine Luxusyacht ist bis zum Rand mit elektrischer Ausrüstung gefüllt. Kritische Geräte zum Segeln laufen normalerweise mit Gleichstrom, die größeren Geräte benötigen Wechselstrom. Generell ist die Klimaanlage der größte Stromverbraucher. Waschmaschinen, Trockner und Meerwasserentsalzungsanlagen sind ebenfalls große Stromverbraucher. Größere Yachten nutzen alle erdenkliche Elektronik, was den Verbrauch noch weiter in die Höhe treibt.

20 kWh bis zu 64 kWh/Tag oder noch mehr

“Normale" und “höhere" und praktisch unbegrenzte tägliche Verbrauchsprofile. Mehr erfahren

Speicherung & Umwandlung

Wie viel Energie soll gespeichert werden?

Die Speicherung von Energie in Batterien hilft, den Verbrauch des Generators zu reduzieren. Wenn Sie während der Nacht Batterien statt eines lauten (Haupt-)Generators benutzen, schlafen Sie ein und hören den Vögeln in der Lagune zu. Im Idealfall hat die Hausbatterie genug Kapazität, um die kritischen Nutzer des Bootes für mindestens 24 Stunden zu unterstützen.

Erzeugung

Woher kommt die Energie?

Die gewaltige Menge an Energie muss erzeugt werden. Das Netz auf einer großen Luxusyacht kombiniert typischerweise verschiedene Quellen, um den Bedarf zu decken. Das Rückgrat wird drei Phasen verwenden, um die größten Lasten abzudecken.

Im Yachthafen wird die Yacht an den dreiphasigen Landstrom angeschlossen. Die Motoren des Bootes können zumindest einen Teil der Energie während der Fahrt liefern. Oftmals benötigen sie die Unterstützung von (mehreren) Generatoren oder Batterien, um alles am Laufen zu halten. Solarmodule können nicht die gesamte benötigte Energie liefern, aber sie können helfen, Treibstoffkosten für die Generatoren zu sparen.

Große Yachten sind oft mit zwei Generatoren ausgestattet. Der Hauptgenerator deckt die gesamte Stromversorgung ab, die Sie für eine große Party benötigen. Ein kleinerer zweiter Generator (in Hybridkombination mit den Batterien) könnte mit weniger Personen an Bord verwendet werden, eine superleise Version könnte nachts die Klimaanlage betreiben, wenn es draußen heiß ist, oder die Fußbodenheizung, wenn es kalt ist.

Die Auswahl der richtigen Victron-Lösung für Ihre Yacht ist die Aufgabe eines Experten. Ihr Victron-Experte hilft Ihnen gerne, das Beste vom Besten an Bord zu bekommen.

Das komplette System

Ein genauerer Blick

Wie übersetzt sich das Energieprofil in ein System? Hier ist unsere Empfehlung für eine durchschnittlich große Yacht.

Hausbatterie:

AC Devices

Everything you would expect in a large home can also be found on a luxury home. All these devices need AC to run. Think of:

  • Entertainment suite
  • Television(s)
  • Office with computers, etc.
  • Phone chargers
  • Fridge and freezer
  • Coffeemaker
  • Breadmaker
  • Dishwasher
  • Microwave
  • Mixer
  • Wine cooler
  • Washing machine
  • Tumble dryer

BatteryProtect

Discharging a battery too far will damage it. Adding a Victron BatteryProtect disconnects the battery when the voltage drops below a pre-set level. No damage done.

There is more to a Victron BatteryProtect. Built-in shutdown delays ensure vital electronics aren’t disconnected in error, i.e. when starting an engine causes a short drop in voltage. It will also automatically reconnect everything when the battery is sufficiently recharged.

BatteryCombiner

The Cyrix BatteryCombiner is the only safe way to connect the house battery to the starter battery (to start your boat’s engines). With a BatteryCombiner you can charge the house battery from the alternator without running the risk of draining the starter battery (which always should be ready to go). When other sources of power are available (eg. shore/solar/generator power), the Cyrix BatteryCombiner will allow bi-directional charging from the house battery to the starter battery.

When the Voltages of the starter and house batteries are the same, use a Cyrix: its current rating should be equal or bigger than the current rating of the alternator. If the house battery is Lithium and the alternators Amperage is smaller than the house battery, or when the Voltages of the starter and house battery are different: use a DC-DC converter or Buck-Boost.

Battery Monitor

A battery monitor is like a "fuel gauge" for your battery. It records how much power is consumed and charged. The battery monitor calculates the state of charge, remaining capacity and time till empty. The battery voltage does not give an accurate indication of how full the battery is. A battery monitor does.

Victron battery monitors keep track of historical data, like the number of charging cycles, deepest discharge, highest voltage, lowest voltage and so on. It will alert you to critical conditions such as low voltage or low charge. The smart monitor can even shut down the entire power supply to avoid expensive battery damage.

Choosing a BMV:

  • Choose a BMV 700 battery monitor if you want to monitor the house battery and don’t need a Bluetooth connection.
  • Choose a BMV 702 battery monitor if you want to monitor both the house battery and the starter battery, and you don’t need a Bluetooth connection.
  • Choose a BMV 712 battery monitor if you want to monitor both the house battery and the starter battery via Bluetooth on a smartphone or tablet.

Boat engines

Large yachts are equipped with marine engines similar to those in commercial vessels. The engines are designed to run continuously, for weeks on end. They come with high-output alternators to charge the engine batteries, drive fuel pumps, etc. They are also intended to power DC equipment like the desalination plant, winches, navigation, refrigeration, etc.

Boat Network

Keeping grips on all the systems on board can be a hassle. The solution: tie everything together in a single boat network using NMEA communication standards. Your boat network can include navigation equipment, tank senders, battery monitoring and much more. The status information can trigger alarms and shutdowns, adding to the safety on board. The Cerbo GX now supports the NMEA2000 out protocol, allowing you to monitor your boat’s network of systems from wherever you are.

Cerbo GX

The Victron Cerbo GX is the communication-centre of your boat’s installation, allowing you to always have perfect control from wherever you are and maximises its performance. Simply connect through our Victron Remote Management (VRM) portal, or access directly, using the optional GX Touch 50 screen, a Multi Functional Display or our VictronConnect app thanks to its added Bluetooth capability.

The Victron Cerbo GX is an easy to use visual system. Instantly monitor the battery state of charge, power consumption, power harvest from PV, generator, and mains, or check tank levels and temperature measurements. Easily control the shore power input current limit, (auto)start/stop generator(s) or even set quiet periods to avoid starting the generator in the middle of the night. Change any setting to optimise the system, follow up on alerts, perform diagnostic checks and resolve challenges remotely. The Cerbo GX turns any power challenge into an effortless experience.

Boat Electronics

A luxury yacht has a lot of DC equipment on board. Most of these devices are needed to safely operate the ship. The battery should be big enough to support them even when the ship’s engines and generators aren’t running.

  • Boat control panel
  • Log/depth sounder
  • Chart-plotter
  • Navigation / GPS
  • Navtex
  • Auto pilot
  • All-band Radio
  • Satellite comms
  • Maritime traffic identification systems
  • Navigation lights
  • Pumps
  • Blowers
  • Interior lighting
  • Hifi

Generator

Large yachts are often equipped with two or more generators. The main generator (i.e. 50 kW) covers all the power you’ll need to throw a big party. A quiet, smaller generator (i.e. 8 kW) could be used with less people on board or power the air conditioning at night when it’s hot out there, or the floor’s heating when it’s cold.

Adding batteries and Victron’s PowerAssist creates a smart hybrid power concept. It comes with several advantages:

  • Longer generator free periods.
  • Reduced rating of the generator.
  • Reduces shore power requirement.
  • Uninterrupted AC power on board.
  • Increase redundancy and therefore safety.

Bigger yachts with large Lithium (house) battery banks can also have dedicated DC-DC generators to directly charge the batteries.

GX GSM Dongle

A GX GSM module will give you 3G internet connectivity to the on board systems. When the boat is in range of a 3G network, it will send data to the VRM website and you can monitor the boat from your smartphone. The GSM module adds tracking the boat, recording your trips and putting up a geo-fence around the boat. You will get an alert via mail when the boat travels outside the geo-fence area.

House battery

The house battery stores power for the boat’s electrical system. Large yachts come with large power demands and the house battery should have a very large capacity.

For a house battery you can choose from two types: lead-acid and lithium. There are various reasons to favour one over the other. Here are a few common ones:

  • Choose Lead-Acid when:
  • Use occasionally
  • Lower purchase cost
  • Weight and space are not an issue
  • Normal charging
  • Choose Lithium when:
  • Use daily
  • Lower cost per cycle
  • Weight and space considerations
  • Fast charging

House battery

The house battery stores power for the boat’s electrical system. Large yachts come with large power demands and the house battery should have a very large capacity.

For a house battery you can choose from two types: lead-acid and lithium. There are various reasons to favour one over the other. Here are a few common ones:

  • Normal charging
  • Choose Lithium when:

Isolation Transformer

An isolation transformer prevents electrolytic corrosion. The transformer is mounted directly behind the shore power connector on board. It blocks DC currents that might leak through the shore power earth terminal. These currents can cause corrosion to all metal parts under water, like the hull, propeller, shaft, etc. The isolation transformer should have the same power rating as the incoming shore power.

It’s a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore-side supply. It might therefore be tempting not to connect the ground conductor: this is however extremely dangerous because Ground Fault Current Interrupters will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.

The safe option is to use an isolation transformer for metal boats or boats with bigger systems, sized in line with how much Watts the boat will consume from shore power.

Inverter/Charger

A large yacht will take a three phase shore power supply. The large generator on board will also deliver three phases; it will run most of the day. A smaller second generator (in hybrid combination with the batteries) could be used with less people on board. a super silent version could power the air conditioning at night when it’s hot out there, or the floor’s heating when it’s cold. Without airconditioning, the inverter/charger can supply power from batteries during the night and act as a backup for the generator(s).

  • Victron inverter/chargers come with a handful of outstanding features:
  • PowerControl: automatically manage battery charging to prevent an overload of the generator or shore power.
  • PowerAssist: uses the batteries as a buffer to assist the generators or shore power during peak power demand.
  • Perfect power: even sensitive devices run flawlessly and uninterrupted on the pure sine wave power.
  • High peak-power: use heavy motorised equipment without overheating.
  • Optimize the use of a larger main generator and a smaller secondary generator.
  • Use the power stored in batteries to create a quiet generator free period.
  • Increase redundancy and safety.
  • Low self consumption.
  • Multiple Quattros can be joined to create a three phase supply upwards of 60kW (Victron can even size up to 180kVa, but that’s way too much for a Yacht).

Thanks to Victron’s PowerAssist, the generator doesn’t have to be sized for the maximum load. You can use a smaller generator which is cheaper to install, uses less fuel and produces less noise. Also, peak demand can be met by combining the generator with Victron Quattro inverter/chargers.

A three phase inverter/charger system always consists of three interconnected inverter/chargers. Throughout the boat you’ll find three phase and single phase loads. The three phases are split into several single and three phase groups. Each group powers a number of devices. There is a switchboard in the boat, like you’ll find in your home.

Lynx ion BMS

The Lynx Ion BMS is a dedicated battery management system (BMS) that protects lithium batteries against deep discharges, overcharging and high temperatures. When critical values are exceeded, the BMS acts immediately: loads are disconnected physically in case of a deep discharge and charging is stopped when there is a risk of overcharging. High temperatures trigger an immediate end to both charging and discharging.

The Lynx Ion BMS is tailored for the 24 or 48 Volt HE lithium batteries. It comes in two ratings of 400 and 1,000 Amps to fit even the biggest systems. Loads and charging power are disconnected automatically in case of deep discharges, overcharges and high temperatures. Battery monitoring is built into the The Lynx Ion BMS; no separate battery monitor is needed.

MFD GX Integration

The Marine MFD GX integration enables you to easily connect a Multi Functional Display (MFD) to the heart of your power system such as the Cerbo GX, or the GX enabled Multiplus-II GX. Once connected you can easily monitor and control your boat’s power system, right on your Glass Bridge. Now available on the industry’s best MFDs, such as Raymarine, Garmin, Simrad, B&G and Lowrance.

3 Phase Loads

Everything is bigger on large luxury yachts. DC or single phase AC often isn’t enough to run the powerful thrusters, winches, pumps and pressure-washers. They need three phase AC to quench their thirst for power.

Professional kitchens and catering equipment come with appliances that take three phase AC. The boat might also have a three phase electrical boiler to provide hot water to several bathrooms and taps at the same time.

Examples of three phase equipment:

  • Heavy windlass
  • Heavy pumps
  • Hydrophore
  • Deck winches
  • Bow thruster
  • Stern thruster
  • Boiler
  • Professional kitchen equipment
  • Desalination plant
  • Air conditioning

Orion-TR Smart DC/DC charger

The Orion-Tr Smart DC/DC charger is used in dual battery systems, where the (smart) alternator and the start battery are used to charge the service battery (of equal or different voltages). The Orion Tr-Smart charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries and can be parallel connected to increase the output current.

Charging lithium batteries from the alternator

Alternators cannot be connected directly to most lithium batteries. A lithium battery will draw more current than the alternator can supply, which may result in alternator damage. A Orion-Tr Smart DC/DC charger solves this problem: it acts as a current limiter between the alternator and the battery: the battery can be safely charged without blowing up the alternator.

Please check your manufacturer for the maximum charging current of your alternator and size the configuration of DC-DC converters accordingly (the current rating of the DC/DC charger has to be less than the alternator’s current rating, or programmed to deliver less Amps).

Starter Battery

The starter battery is needed to start your boat’s engines. These batteries are different from house batteries and engineered to deal with a large discharge current. The starter batteries should be ready to go. Always use a BatteryCombiner to connect the starter batteries to the rest of the electrical system; it prevents an accidental drain of power.

Solar panels

More and more yachts area equipped with solar panels. Although they will never be able to cater for all the power needed, they can reduce the running time of the generator and fuel costs. Victron offers a wide range of highly efficient solar panels that are just perfect for marine use.

Shore Power

Usually shore power is available in the marina; it is used to run large AC equipment on board and recharge the batteries. Larger boats need a three phase supply. Sometimes shore power can’t provide enough power to cater for the total AC load of the boat. It might also just be single phase.

Often shore power is limited in how much power you can draw, i.e. just 10 Amps. Berths with higher ratings might not always be available. Victron inverter/chargers allow you set a maximum shore power current. Now you can charge your batteries and turn on any equipment without blowing a fuse. Thanks to Victron’s PowerAssist, the generator and batteries can automatically bridge the gap between supply and demand.

Sometimes shore power is less than perfect. You might run into voltage drops if you’re at the far end of the harbour. There could also be power surges, which could harm sensitive equipment on board. Victron’s inverter/chargers smooth out these problems and turn bad power into perfect power.

Solar charger

A solar charger harvests the power from the solar panels to charge the house batteries. Solar chargers have the same charging cycles as a regular, fully automatic, battery charger.

In a marine environment, the performance of solar panels changes constantly. Victron’s solar controllers use ultra fast maximum power point tracking to squeeze every drop of power out of the panels.

GX Touch

The GX Touch 50 display allows you to have an instant overview of your system and adjust settings in the blink of an eye. Simply connected to the Cerbo GX with one cable, its super slim 5 inch waterproof design and its top-mountable setup bring a lot of flexibility when creating a crisp and clean dashboard.

VictronConnect

All Victron products on your boat can be monitored and controlled from the palm of your hand. Just connect the VictronConnect App via Bluetooth and you’ll have direct access to values like battery voltage and current. You can also turn devices on or off, as well as change their settings.
