Lille Båd

Få mere nydelse ud af din sejltur.

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.

Den optimale energiplan

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.

Forbrug

Hvor meget skal du bruge?

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.

0,6 - 1,2 kWh/dag

’Normal’ og ’tungere’ daglige forbrugsprofiler. Læs mere

Eksempel 1

Lysene bruger måske 100 W/time, men bruges kun 4 timer om dagen.
100 W x 4 timer = 0,4 kWh/dag

Eksempel 2

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

Opbevaring & konvertering

Hvor meget energi bør opbevares?

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 230V. 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.

x 2

Opbevaringskapaciteten på et Lithium-batteri bør være to gange det daglige energiforbrug.

x 4

Grundet dens mindre afladningskapacitet, bør opbevaringskapaciteten af en blybatteri være fire gange højere end det daglige energiforbrug.

Konvertering

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).

Dannelse

Hvor kommer energien fra?

Du har nogle muligheder for at generere den energi, du skal bruge på turen. Du kan benytte energikilderne i marinaen. Eller - hvis du tager din båd med hjem på en trailer - kan du koble den til i garagen. Ude på vandet kan du bruge generatoren på bådens motor.

Komplet system

Tættere på

Hvordan kan denne energiprofil oversættes til et system? Her er vores anbefaling til en gennemsnitlig, lille båd.

Husbatteri:

Indlæsning

AC devices

Devices you bring on board usually need an AC outlet. Think of:

  • Phone charger
  • Laptop
  • Drone batteries

Battery charger

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 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.

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 Orion or Buck-Boost.

BatteryProtect

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. Built-in shutdown delays ensure vital electronics aren’t disconnected in error, i.e. when starting the engine causes a short drop in voltage.

BMS 12/200

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.

Boat engines

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.

Boat Electronics

A small boat will have several electronic devices; they all run of the house battery. Think of:

  • Boat control panel
  • Log/depth sounder
  • Chart-plotter or GPS
  • VHF Radio
  • Navigation lights
  • Pump – Bilge, deck wash
  • Fridge
  • Interior lighting
  • Music player
  • Bait Tank – Recirculating
  • Electric Fishing Reels/winches

House battery

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:

  • 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

Inverter

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.

Starter Battery

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.

Shore Power

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.

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 indicators like battery voltage and current. You can also turn devices on or off, as well as change their settings.
