Nyd lyden af stilhed

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.

Hvor meget energi har du brug for på din sejltur?

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.

Forbrug

Hvor meget skal du bruge?

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.

1,2 - 2,4 kWh/dag

’Normalt’ og ’tungere’ energiforbrug.Læs mere

Eksempel 1

Mikroovnen bruger 1000 W på en time, men det er kun i 2 minutter om dagen.
1000 W/60 x 2 = 0,3 kWh/dag

Eksempel 2

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 & konvertering

Hvor meget energi bør opbevares?

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.

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?

Al energi skal dannes, før du kan bruge den. Victron lader dig kombinere en række muligheder. Du kan benytte energikilderne i marinaen. Det kan være begrænset til nogle få ampere, men det er plug-and-play. Mens du sejler kan du bruge en (ekstra) generator på bådens motor. Yachter, der er større end gennemsnittet, bruger generatorer se vores andet eksempel. Dog ødelægger støjen fornøjelsen af sejladsen. Endelig kan du også bruge solceller for at få energi gratis.

Komplet system

Tættere på

Hvordan kan denne energiprofil oversættes til et system? Her er vores anbefaling for en gennemsnitlig yacht.

Husbatteri:

AC devices

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:

  • Phone charger
  • Laptop
  • Television
  • Refrigerator
  • Microwave

Being able to plug-in these device saves you the trouble of finding a DC version.

Boat engines

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.

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. 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 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.

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 BMS.

See our bigger boat types to see a bigger Lithium system and BMS See more info on alternator charging Lithium (and not blow them up)

Boat Electronics

A sailing yacht is home to several electronic devices. These are all connected to the house battery. Think of:

  • Boat control panel
  • Log/depth sounder
  • Chart-plotter or GPS
  • Navtex
  • Auto pilot
  • VHF Radio
  • Navigation lights
  • Pumps
  • Windlass
  • Bow thruster
  • Fridge
  • Interior lighting
  • Music player

Cerbo GX

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.

Galvanic Isolator

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.

GX GSM Dongle

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.

House battery

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:

  • 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/Charger

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.

  • Victron inverter/chargers come with a handful of outstanding features:
  • PowerControl: automatically manage battery charging to prevent an overload of the generator or shore power.
  • PowerAssist: uses the battery as a buffer to assist the shore power during peak power demand.
  • Perfect power: even sensitive devices run flawlessly on the pure sine wave power.
  • High peak-power: use motorised equipment without overheating.
  • Low self consumption.

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.

Shore Power

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.

Solar charger

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

Solar panel

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

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 important starter battery from all other electrical circuits on board, so it cannot be accidentally drained of power.

VE.Direct Bluetooth Smart dongle

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.

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