Store lystbåde giver luksus og komfort ud over de fleste hjem. Eller endda hoteller. Du finder dig selv på tur i fuldt udstyrede køkkener, nyder en underholdningsrum i topklasse og tager dig af arbejdet i et sofistikeret kontor. Victron matcher niveauet af luksus med det nyeste energiudstyr, der giver dig fuld selvstændighed i flere måneder.
Lad os antage, at du bruger en del af året i dit andet, flydende hjem. Den store forsyning om bord giver dig friheden til at blive væk fra kysterne i flere uger, så du kan lægge til i din yndlingsbugt. Takket være et fuldt udstyret kontor om bord, kan du som sædvanligt arbejde med en udsigt selv ikke dit kontor på Manhattan kan matche.
Hvad er denOptimale energiplan, der gør det hele muligt?
En luksusyacht er fyldt til bristepunktet med elektrisk udstyr. Kritisk udstyr til sejlads kører typisk på jævnstrøm, mens større udstyr kræver vekselstrøm. Generelt er air conditioning den største forbruger af energi. Vaskemaskiner, tørretumblere og afsaltningsanlæg er også store forbrugere af energi. Større yachter bruger al den form for elektronik, som du kan forestille dig, hvilket øger forbruget yderligere.

Opbevaring af energi i batterier hjælper med at spare på generatorbrug. At benytte batterier i stedet for en støjende (hoved)generator i løbet af natten lader dig falde i søvn til lyden af fuglene i lagunen. Ideelt har et husbatteri en stor nok kapacitet til at støtte kritiske brugere på båden i mindst 24 timer.
Den massive mængde energi skal dog dannes. Netværket på en stor luksusyacht kombinerer typisk forskellige kilder for at møde efterspørgslen. Rygsøjlen udgøres af tre faser, der leverer til de største belastninger.
I marinaen vil yachten være koblet til en trefaset energikilde på kysten. Bådens motor kan give mindst en del af energien, mens der sejles. Ofte har de brug hjælp fra generatorhjælp (eventuelt hjælp fra flere generatorer) eller batterier, der holder alt kørende. Solceller kan ikke dannes al den energi, der er behov for, men de kan hjælpe med at holde omkostningerne fra generatorerne nede.
Store yachter er ofte udstyret med to generatorer. Hovedgeneratoren dækker al den energi, du skal bruge for at holde en stor fest. En mindre, sekundær generator (i hybridkombination med batterierne) kan bruges, hvis der er færre personer om bord, en super-stille version kan forsyne air condition om aftenen, når det er varmt udenfor eller gulvvarmen, når det er koldt.
At vælge den rigtige Victron-løsning til din yacht er en eksperts opgave. Din Victron Professional hjælper dig med glæde med at få det bedste af det bedste ombord.
Hvordan kan denne energiprofil oversættes til et robust system?
Alt hvad du kan forvente dig i et stort hjem og også i et luksushjem. Alle disse enheder skal bruge AC strøm til at fungere. Tænk på:
For dyb afladning af et batteri vil beskadige det. Når der tilføjes en Victron BatteryProtect kobles batteriet fra når spændingen falder under et forudindstillet niveau. Der sker ingen skade.
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.
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.
Når spændingerne på starter- og husbatterierne er ens, brug en Cyrix: dens spændingsværdi skal være lig med eller større end den nuværende værdi på generatoren. Hvis husbatteriet er Lithium og generatorens strømstyrke er mindre en husbatteriet eller når spændingerne på starter- og husbatteriet er forskellige: brug en DC-DC converter eller Buck-Boost.
Battery management systems take excellent care of Lithium batteries, protecting the individual cells of LiFePO4 batteries against over voltage, under voltage and over temperature and will shut down or reduce charging (VE.Bus products only) or disconnect the loads when this occurs.
Victron Energy offers several BMS options, in general the VE.Bus BMS and smallBMS signal separate devices to disconnect the charging (Inverter/Chargers, Cyrix-Li, DC-DC chargers) or disconnect the loads (BatteryProtect, Inverter/Charger), the modular Lynx distribution system features the Lynx BMS and other modules for more control over the DC busbar. For vehicles and boats all-in-one functionalities are available in the Smart BMS versions for Victron Lithium batteries, but also include current limiting to protect the alternator from overheating and BatteryProtect-like functionality to shut down the loads when pre-set critical battery conditions are met.
Victron Energy also offers full flexibility when it comes to selecting a third-party off-grid battery bank (and their BMS) of choice. A large number of well supported Lithium battery manufacturers can be easily integrated through the use of a mandatory GX-device. This flexibility enables our customers to perfectly match their off-grid needs for their unique power situation. When working with unsupported brands, a Victron Energy Battery Monitor is required to pass on accurate state of charge readings to the wider system.

En batterimonitor er som en "måler på brændstoffet" for dit batteri. Den registrerer, hvor meget strøm der forbruges og oplades. Batterimonitoren beregner ladetilstanden, resterende kapacitet og tid til opladning. Batterispændingen giver ikke en nøjagtig indikation af, hvor fyldt batteriet er (især ikke under belastning). En batterimonitor gør.
Victron Energy batterimonitorer holder styr på historiske data, såsom antallet af opladningscyklusser, dybeste afladning, højeste spænding, laveste spænding og meget mere. Den vil advare dig om kritiske forhold såsom lav spænding eller lav opladning - og kan endda lukke for hele strømforsyningen for at undgå dyre skader af batteri eller starte en generator.
Victron tilbyder batterimonitorer med eller uden display, Smart-versioner giver dig mulighed for at spore de detaljerede data og justere indstillinger i vores gratis VictronConnect-app.
De fleste lithiumsystemer kræver et batteristyringssystem, som kan give batterioplysninger til det større system. På denne rute kan en batterimonitor blive overflødig. Se batteristyringssystemet for at få flere oplysninger Se alle vores batterimonitorer
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.
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.
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.
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.
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:
Bigger yachts with large Lithium (house) battery banks can also have dedicated DC-DC generators to directly charge the batteries.
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.
Et GX 4G-modul tilføjer mobil internetforbindelse til dit Victron Energy-system. Når dit system er inden for rækkevidde af et 4G-netværk, sender det data til VRM-webstedet, og du kan overvåge systemet fra din smartphone. Modulet tilføjer GPS-sporing, registrerer dine ture og opsætter et geo-hegn omkring installationen. Du får en advarsel via mail, når systemet kører uden for geo-hegnområdet.
Victron Energy tilbyder flere 4G moduler og GlobalLink 520-modemet, som fungerer uden månedlige gebyrer eller abonnementer, i de første fem år og flere 4G-moduler. Se vores 4G modems Se vores GlobalLink 520
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:

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.
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).
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.
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.
The Victron integration between our GX range and several leading Multi Functional Display manufacturer brands enables you to easily connect an MDF 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.
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:
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).
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.
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.
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.
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.
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.
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.

Lynx Smart BMS er et dedikeret batteristyringssystem til Victron Lithium Smart Batterier (til andre batterier end Victron, se nedenfor). Der er flere BMS-er tilgængelige til vores Smart Lithium-batterier, og Lynx Smart er den mest funktionsrige og komplette mulighed. Dens hovedfunktioner er:
Det dedikerede system til batteristyring (BMS) beskytter lithiumbatterier mod dybe afladninger, overopladning og høje temperaturer. Når kritiske værdier overskrides, tager BMS handling med det samme: belastninger afbrydes fysisk i tilfælde af en dyb afladning, og opladningen stoppes, når der er risiko for overopladning. Høje temperaturer udløser øjeblikkelig afslutning på både opladning og afladning.
Overvågning af batteri er indbygget i Lynx Smart BMS; ingen separat batterimonitor er nødvendig. Med Bluetooth kan batterierne overvåges med VictronConnect, når de er sluttet til en GX-enhed, også med VRM, vores fjernstyringsløsning.
Dette produkt er en del af det modulære Lynx busbar-system, der også leverer Lynx-fordeleren, som er en modulær DC-busbar, der indeholder 4 DC-sikringer og overvåger deres status i VictronConnect og VRM og andre DC forbindelser til at håndtere fordeling, sikring, batteriovervågning og/eller styring af Lithium batterier.
Lynx busbar systemet kan også bruges til DC-fordeling og overvågning af andre batterier end Victron Lithium batterier. I det tilfælde udskiftes Lynx Smart BMS med Lynx Shunt VE.Can til overvågning af et andet batteri. Se alle Lynx-moduler
The Lynx Distributor is a modular DC busbar, with locations for four DC fuses. It will monitor the status of each fuse, and indicate its condition with a LED on the front. When connected to a Lynx Smart BMS or Lynx Shunt, the status of the fuses will be visible in VictronConnect and VRM (when the Lynx Smart BMS is connected to a GX-device).
Multiple Lynx Distributors can be used to connect all the DC-loads and charge sources on one side of the BMS, on the other side, a Lynx Power In (without fuses) or another Lynx Distributor (with fuses) can be used to connect the battery bank to the modular busbar.
