At fange al kraften fra vinden gør sejlads til en uforglemmeligt oplevelse. Det eneste, du kan høre, er lyden af viden, der blæser og bølgerne, der bryder. Men hvad er den bedste måde at forsyne elektronik om bord, mens motoren og generatoren er slukkede? Victron kombinerer energiopbevaring og dannelse fra solceller for at skabe den energi, du har brug for. I absolut stilhed.
Uanset om du sejler væk for en weekend eller planlægger en tur rundt om jorden, så er der store chancer for, at den samme Victron-løsning vil passe til begge ture. Det er i virkeligheden niveauet af komfort, der afgør din optimale løsning om bord. Med Victron kan du sejle gennem stort set alle planer, men som et eksempel har vi illustreret ’normal’ og ’tungere’ energiprofiler i en 'gennemsnitlig’ yacht nedenfor.
Lad os kaste et blik på din Optimale energiplan.
En moderne yacht er fyldt med elektrisk udstyr. Oftest kan båden klares sig med jævnstrøm i sin normale drifts, mens større (husholdnings) udstyr bruger vekselstrøm. Når det kommer til at estimere energiforbrug, lægger man blot Watt sammen. Tiden er dog ligeså vigtig. En mikroovn bruger måske 1000 Watt, men kun i 2 minutter. Et køleskab bruger måske så lidt som 50 Watt, men det er tændt 24 timer i døgnet.
Som inspiration har vi fremhævet 2 systemeksempler baseret på ’normal’ og ’tungere’ brug.
Mikroovnen bruger 1000 W på en time, men det er kun i 2 minutter om dagen.
1000 W/60 x 2 = 0,03 kWh/2 minutter
Køleskabet bruger 50 W/time, men er tændt hele dagen (og køler faktisk hele dagen).
50 W x 24 timer/2 = 0,6 kWh/dag
Opbevaring af energi tillader dig at leve af energi fra kysten, eller giver dig muligheden for at bruge den solenergi, du har høstet om dagen, i løbet af natten. Inverteren vil konvertere opbevaret energi til 230 V. Yachter oplever typisk lange intervaller mellem batteriopladninger, så dit husbatteri bør have en generøs kapacitet. Som tommelfingerregel regner vi altid med 48 timer om bord uden energi fra kysten/motoren/generator/solceller. Gang dit daglige energiforbrug med dage for en endnu større uafhængighed.
Opbevaringskapaciteten på et Lithium-batteri bør være to gange det daglige energiforbrug.
Grundet dens mindre afladningskapacitet, bør opbevaringskapaciteten af en blybatteri være fire gange højere end det daglige energiforbrug.
Inverteren bør være stor nok til at håndtere den gennemsnitlige belastning kontinuerligt, og den bør matche den forventede peak-spænding, hvilket vores inverterer håndterer fint (gennemsnitligt 2 x deres kontinuerlige spænding).
Normal og tungere energiprofiler i kWh baseret på det daglige energiforbrug, hvilket bør være i balance med dannelsen.
Opbevaringsbatterier i Ah, dobbelt så stor en kapacitet ved hjælp af blybatterier.
Hvordan kan denne energiprofil oversættes til et robust system?
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
You’ll want to bring small devices on board for your trip. Or use household appliances like a microwave. These usually run of an AC outlet. Think of:
Being able to plug-in these device saves you the trouble of finding a DC version.
Sailing yachts have one or two diesel engines (Catamarans) to get from harbour to horizon. The engines come with alternators to charge the engine batteries, drive fuel pumps, etc.
Once the starter batteries are recharged, the engines can also power the boat electrics and recharge the house battery. On bigger yachts you’ll find power hungry DC equipment such as anchor windlasses and bow thrusters. The engines have to be running before you can use them.
Discharging your battery too far will damage it. Adding a Victron BatteryProtect will disconnect the boat’s electronics when the battery voltage drops below a pre-set level. It will also automatically reconnect everything when the battery is sufficiently recharged.
There is more to a Victron BatteryProtect. The built-in shutdown delay ensures that vital electronics aren’t disconnected in error, i.e. when starting the engine causes a short drop in battery voltage.
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
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 Orion or Buck-Boost.
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 BMS 12/200 is a dedicated battery management system (BMS) that protects Victron Smart 12,8V LFP batteries against deep discharges, overcharging and high temperatures with up to 200 Amps maximum DC current. 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.
This is the only BMS that can be directly connected to an alternator, protecting them from overload/overheating. This works with a combination of an AB fuse (rated in accordance with the expected max load current of the alternator) and an internal programmable input (which limits the input current electronically to 80% of the AB fuse).
Please check your manufacturer for the maximum charging current of your alternator and size AB fuses of the BMS 12/200 accordingly, see manual.
When different Lithium batteries & higher voltages are used, other solutions are needed, such as the VE.bus BMS and Lynx Ion BMS.

A sailing yacht is home to several electronic devices. These are all connected to the house battery. Think of:
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.
DC-DC konvertere, eller batteri-til-batteri opladere (konvertere med indbyggede ladealgoritmer) bruges i dobbeltbatteri systemer, hvor den (smarte) generator og startbatteriet er kombineret med servicebatteriet (på lige fod eller forskellige spændinger) for at oplade den. De kan også bruges til at oplade applikationer, der har dedikerede batterier (for eksempel bovpropel), eller til at forsyne applikationer med en anden spænding end servicebatteri-banken.
De fleste DC-DC opladere kan anvendes i 12 V eller 24 V systemer, og alle er velegnede til både blysyre- og lithiumbatterier. Nogle DC-DC opladermodeller kan parallelkobles for at øge udgangsstrømmen. DC-DC opladere er en perfekt og sikker løsning til at oplade Lithium batteri banker fra smarte generatorer (og blysyre-batterier for den sags skyld).
Opladning af lithiumbatterier fra generatoren
De fleste generatorer kan ikke tilsluttes direkte til lithiumbatterier. Et lithiumbatteri vil trække mere strøm, end generatoren kan levere, hvilket kan resultere i permanent skade på generatoren. For ikke at beskadige generatoren er strømbegrænsning en af mulighederne for at forblive inden for generatorens sikre zone.
Victron tilbyder flere løsninger til at løse det her problem, hvoraf en af dem er DC-DC-konverterne:
The Victron GX GSM is a 3G cellular modem that enables GX devices with mobile internet for the system and connection to the VRM Portal, allowing you to monitor your system from remote. 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.
Victron Energy Cerbo GX er kommunikationscentret for din systeminstallation, der giver dig mulighed for altid at have fuld kontrol, uanset hvor du er, og maksimerer dens ydeevne. Den valgfrie GX Touch 50 er en ledsager til Cerbo GX, dens fem tommer touchskærm giver et øjeblikkeligt overblik over dit system og giver dig mulighed for at justere indstillinger på et øjeblik.
Overvåg øjeblikkeligt batteriets opladningstilstand, energiforbrug, energiudvinding fra PV, generator og hovedledning, eller kontroller tankniveauer og temperaturmålinger. Styr nemt strømgrænsen for landstrøm, (auto)start/stop generator(er) eller indstil endda stille perioder for at undgå at starte generatoren midt om natten. Skift enhver indstilling for at optimere systemet, følge op på advarsler, udføre diagnostiske kontroller og løse udfordringer eksternt med den gratis Victron fjernstyringsportal (VRM).

Du skal blot oprette forbindelse via vores portal for Victron fjernadministration (VRM), eller få adgang direkte ved hjælp af GX Touch 50, en MFD eller vores VictronConnect-app takket være den ekstra Bluetooth-funktion.
A galvanic isolator prevents electrolytic corrosion. The isolator 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 galvanic isolator 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 a Galvanic Isolator for non-metal smaller boats, or use an isolation transformer for metal boats or boats with bigger systems.
The house battery stores power for the boat’s electrical system. Sailing yachts typically have long intervals between battery recharges and the house battery should have a generous 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:

The inverter/charger is the heart of the system. In the marina, it charges the batteries from shore power. While sailing it inverts the energy from the boat’s battery into AC power for household devices. The switch from charging to inverting and from inverting to charging is seamless.
For this power profile we would recommend:
We would recommend our Multiplus-II inverter/charger. If you have a generator on board you’ll need a Quattro inverter/charger, which has an extra input (shore power and generator).
We strongly recommend 24 Volts for new boats. The higher voltage is simply a better choice when it comes to meeting the power demands of a modern sailing yacht. If your boat’s system is based on 12 Volts, select a 12 Volts unit instead.
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.
In the marina, the boat will be connected to shore power. Shore power recharges the batteries. It can also be used for maintenance and to run large AC loads.
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.
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- also called MPPT controller, harvests the power from the solar panels to charge the house battery. Solar chargers have the same charging cycles as our regular, fully automatic, battery chargers. When your boat is moored without shore spower, solar power is a great way to keep the batteries charged.
In a marine environment, the performance of solar panels changes constantly. Victron’s solar controllers use ultra fast maximum power point tracking to squeeze up to 30% more power out of your panels.
The rating of the solar charger is defined by the size of the solar panel. For solar panels of less than 150W or less, choose a 75/10 charger. If your solar panel produces between 150 and 220W, pick a 75/15 instead.
See our Solar Calculator to size the solar panels and select a MPPT charger
More and more sailing yachts area equipped with solar panels. After all, they extend the autonomy range without the noise of a diesel engine and… for free. Victron offers a wide range of small, highly efficient, solar panels that are just perfect for boats.
See our Solar Calculator to size the solar panels
The starter battery is needed to start your boat’s engine. These batteries are different from house batteries and engineered to deal with a large discharge current. The starter battery should always be ready to go. It’s best to isolate the important starter battery from all other electrical circuits on board, so it cannot be accidentally drained of power.
The Bluetooth dongle enables you to use the VictronConnect app with VE.Direct enabled devices (without Bluetooth built-in). With the app you can have real-time insight and full control, and you can access all VE.Direct enabled devices such as the smaller VE.Direct inverters, the BMV 70x series battery monitors or MPPT solar controllers.
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.
