At få båden af traileren og sejle ud på vandet er ren magi. Uanset om du skal af sted på en fisketur, wakeboarding eller øhop i et par dage, er en sejltur lig med frihed. Du vil have den samme følelse, når det kommer til energi. Friheden til at oplade din telefon og afspille din yndlingsmusik uanset hvor du er. Victrons smarte energiløsning leverer den frihed til enhver lille båd.
Forestil dig, at du tager en ven med at fiske i weekenden. Påhængsmotoren fører din lille båd ud på midten af søen. Dagens fangst vil også være aftensmaden, før I slår lejr for natten på en lille ø.
Lad os overveje den Optimale energiplan, der hjælper dig med at nyde turen i komfort.
Selv en lille båd afhænger af elektrisk udstyr. Båden kommer med udstyr, som er afhængigt af jævnstrøm, men hvis du ønsker at have mulighed for at oplade din telefon eller bærbare, og det kræver vekselstrøm. Alt, der er elektrisk, kræver en vis mængde Watt. At lægge Watt sammen er dog kun halvdelen. Tid er også vigtigt. Du har måske 100 Watt i lys på båden, men de er kun tændt i en begrænset periode. En lille køleboks tager op til 50 Watt, men den kører hele tiden.
Som inspiration har vi fremhævet 2 systemeksempler baseret på ’normal’ og ’tungere’ brug.
Lysene bruger måske 100 W/time, men bruges kun 4 timer om dagen.
100 W x 4 timer = 0,4 kWh/dag
Køleboksen bruger 50 W/time, men den er tændt hele dagen (og køler det mest af dagen)
50 W x 24 timer/2 = 0,6 kWh/dag
Du ønsker ikke at lade motoren være tændt hele tiden. Det vil skræmme fiskene væk. Løsningen er at opbevare energi i et (hus)batteri, hvor inverteren så konverterer den opbevarede energi til 230 V. Batteriet kan på turen oplades med strøm fra kysten og fra en generator. Hvis du planlægger efter, at turen skal vare nogle dage, så skal du som tommelfingerregel være sikker på, at dit batteri har kapacitet nok til at støtte dig i op til 48 timer.
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?
Devices you bring on board usually need an AC outlet. Think of:
As the name suggests: the battery charger recharges the boat’s battery when plugged into shore power. At the same time the Victron battery chargers will also power the boat’s electrics.
All Victron battery chargers operate automatically. You can safely keep them connected to the battery all the time, even when the boat is not in use. Waterproof chargers are also available.
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.
BatteryProtect-funktionen afbryder batteriet fra enheder, der ikke er væsentlige, før det er helt afladet (hvilket kan beskadige batteriet), eller før det har utilstrækkelig strøm tilbage til at starte motoren.
Der er mere ved en Victron Energy BatteryProtect. Indbyggede forsinkelser til nedlukning sikrer, at vital elektronik ikke afbrydes ved en fejl, det vil sige at når en motor startes, forårsager det et kort spændingsfald. Den vil også automatisk tilslutte alt igen, når batteriet er tilstrækkeligt opladet.
BatteryProtect har en fjernbetjening, så den kan tændes/slukkes via en BMS eller switch. Den smarte version kan programmeres via VictronConnect appen.
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.

Small motor boats rely on their engine to get the job done. Their engine comes with an alternator to charge the engine batteries, drive fuel pumps, etc.
Once the starter batteries are recharged, the engines can also recharge the house battery and power the boats electronics. When the engine is used the majority of the day, there will always be enough energy generation to compensate the daily consumption. However, when the boat isn’t used over time, batteries might run dead eventually. Our battery chargers take excellent care of your batteries when in the harbour or garage.
A small boat will have several electronic devices; they all run of the house battery. Think of:
Battery chargers recharge batteries (DC) when plugged into shore power (AC).
At the same time the Victron Energy battery chargers can also power devices directly.
All Victron Energy battery chargers are developed for professional duty. Our advanced multi step charging algorithms get the best out of your battery, giving the battery the power it needs, maintaining its health, ensuring better performance... and a longer life.
Smart models work with VictronConnect, so you can check the status and configure all settings of your battery charger remotely via Bluetooth. Chargers with different waterproof ratings (IP rating) are also available. Our wide range of models makes it easy to select the right charger, saving you the cost of having to buy a larger one.

The house battery supplies power to your boat’s electrical system. Choose a battery with a generous capacity as there might be long intervals between re-charges. Sometimes the starter battery doubles up as the house battery. If you opt for this set-up, make sure the battery is well protected against discharge. It will be hard to start the boat when the battery is flat.
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 inverter creates AC power from a DC source. It lets you use devices on board that need a regular AC outlet.
The inverter needs to be big enough to handle the maximum AC load you want to bring on board. If the load exceeds 375 VA, you might consider a combined inverter/charger instead. Models start at 500 VA.
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 starter battery from all other electrical circuits on board, so it cannot be accidentally drained of power, with a BatteryCombiner.
Either in the marina or back home you’ll hook the boats charger up to shore power to recharge the battery. Shore power can also be used for maintenance and to run large AC loads.
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 indicators like battery voltage and current. You can also turn devices on or off, as well as change their settings.
