Liten båt

Få optimal glede av seilasen

Få båten av hengeren og få den på vannet er ren magi. Enten du skal fiske, stå på seilbrett eller øyhopping i noen dager, er seiling frihet. Du vil ha den samme følelsen når det gjelder kraft. Frihet til å lade telefonen din og spille favorittmusikken din uansett hvor du er. Victrons smarte energiløsning gir deg frihet selv i en liten båt.

Den Optimale energiplanen

Se for deg at du tar med en venn for å fiske i helgen. Påhengsmotoren tar den lille båten din til midten av innsjøen. Dagens fangst blir middagen du lager før du slår leir for natten på en liten øy.

La oss vurdere Optimal energiplan som hjelper deg med å glede deg over turen.

Forbruk

Hvor mye trenger du?

Selv en liten båt er avhengig av elektrisk utstyr. Alt montert i båten vil kjøre på likestrøm, men du trenger en stikkontakt til å lade en telefon eller en bærbar PC. Alt elektrisk bruker en viss mengde watt. Å legge sammen watt gir ikke hele bildet. Tid er like viktig. Du har kanskje 100 watt med lys ombord, men de er på på bare i en begrenset periode. En liten kjøleboks tar 50 watt, men kjører hele tiden.

For å inspirere har vi skissert 2 systemeksempler basert på “normal” og “tyngre” bruk.

0,6 - 1,2 kWh / dag

“Normale” og “tyngre” daglige forbruksprofiler. Les mer

Eksempel 1

Lysene bruker kanskje 100 W i timen, men brukes bare 4 timer om dagen.
100 W x 4 timer = 0,4 kWh / dag

Eksempel 2

Kjøleboksen bruker 50 W i timen, men er på hele dagen (faktisk avkjøling & frac12; av dagen)
50W x 24 timer/2 = 0,6 kWh / dag

Lagring & konvertering

Hvor mye energi skal lagres?

Du ønsker ikke å kjøre motoren hele tiden. Den vil skremme vekk fisken. Løsningen er å lagre energi i et (husholdnings) batteri, hvor omformeren konverterer lagret strøm til 230 V. Batteriet kan lades med landstrøm og fra generatoren underveis. Hvis du planlegger turer på kort varsel, må du sørge for at batteriet har nok kapasitet til å støtte deg i 48 timer som en tommelfingerregel.

x 2

Lagringskapasiteten til et litiumbatteri skal være to ganger det daglige strømforbruket.

x 4

På grunn av sin 50% mindre utladningskapasitet, bør lagringskapasiteten til et syrebatteri være fire ganger det daglige strømforbruket.

Omdannelse

Omformeren bør dimensjoneres for å håndtere gjennomsnittsbelastningen kontinuerlig og skal samsvare med den forventede maksimale effekten til lasten, noe som våre omformere takler veldig bra (i gjennomsnitt 2 x deres kontinuerlige strømstyrke).

Generasjon

Hvor kommer kraften fra?

Du har et par alternativer for å generere strømmen du trenger for turen. For det første er det landstrøm i marinaen. Eller - hvis du tar båten hjem på henger - kobler du den til i garasjen. Ute på sjøen kan du bruke dynamoen på båtens motor.

Husholdningsbatteri

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 Management Systems

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.

See all our Battery Management Systems

Battery Monitors

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 (especially not under load). A battery monitor does.

Victron Energy 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 and can even shut down the entire power supply to avoid expensive battery damage, or start a generator.

Victron offers battery monitors with or without display, Smart versions allow you to track the detailed data and adjust settings in our free VictronConnect app.

Most Lithium systems require a Battery Management System, which can feed battery information to the wider system. In this route a Battery Monitor might become redundant. See Battery Management System for more information. See all our Battery Monitors

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

The BatteryProtect disconnects the battery from non-essential loads before it is below a pre-set level (a complete discharge would damage the battery) or before it has insufficient power left to crank an engine.

There is more to a Victron Energy 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 BatteryProtect has a remote switch, so it can be turned on/off via a BMS or switch. The smart version is programmable via the VictronConnect app.

See our range of BatteryProtect models

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

Chargers

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.

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.
