Yate a vela

Disfrute del sonido del silencio

Aprovechar la energía del viento hace de la navegación una experiencia inolvidable Solo querrá oír el viento soplar y las olas romper. ¿Pero cuál es la mejor forma de alimentar los sistemas electrónicos de a bordo cuando el motor y el generador están apagados? Victron combina el almacenamiento de energía y la generación solar para proporcionarle la energía que necesita. En completo silencio.

¿Cuánta energía necesita para su viaje?

Ya esté navegando durante el fin de semana o planeando un viaje alrededor del mundo, es muy probable que la misma solución de Victron le sirva para las dos cosas. El nivel de comodidad es lo que realmente determina la solución a bordo óptima para usted. Con Victron puede alimentar cualquier plan, pero a modo de ejemplo hemos ilustrado un perfil energético ‘normal’ y otro ‘superior’ para un velero ‘medio’.

Echemos un vistazo a su plan de Energía Óptima.

Autoconsumo

¿Cuánto necesita?

Los veleros modernos tienen un montón de equipos eléctricos. La mayoría de los elementos necesarios para operar el barco necesitan CC y los aparatos (domésticos) más grandes necesitan CA. Para estimar el consumo de energía, a menudo solo se suman los vatios. Pero el tiempo es igual de importante. Un microondas puede necesitar 1000 vatios, pero solo durante 2 minutos. Un refrigerador puede necesitar tan solo 50 vatios, pero está encendido las 24 horas del día.

A modo de orientación hemos diseñado dos ejemplos de sistema en función del uso ‘normal’ y ‘superior’.

1,2 - 2,4 kWh / día

Consumo de energía 'normal' y 'superior'Leer más

Ejemplo 1:

El microondas utiliza 1000 W por hora, pero solo está encendido 2 minutos al día.
1000 W / 60 x 2 = 0,03 kWh / 2 minutos

Ejemplo 2:

El refrigerador utiliza 50 W por hora pero funciona durante todo el día (normalmente refrigerando la mitad del día)
50 W x 24 h/2 = 0,6 kWh/día

Almacenamientoy conversión

¿Cuánta energía debe almacenarse?

Almacenar energía le permite vivir de la energía del puerto en altamar o le permite usar por la noche la energía solar almacenada durante el día. El inversor pasará la energía almacenada a 230 V. En los veleros, los intervalos entre cada recarga de las baterías son más largos, de modo que se debe contar con una amplia capacidad. Como regla general, hacemos los cálculos considerando 48 horas a bordo sin suministro de energía del puerto/motor/generador/solar. Multiplique el consumo diario de energía por días para tener aún mayor independencia.

x 2

La capacidad de almacenamiento de una batería de litio debería ser el doble del consumo diario de energía.

x 4

Debido a su capacidad de descarga un ± 50% inferior, la capacidad de almacenamiento de una batería de ácido y plomo debería ser cuatro veces el consumo diario de energía.

Conversión

El inversor debería estar dimensionado para manejar la carga media de forma continua y ajustarse a la corriente de potencia pico de las cargas, algo que nuestros inversores manejan muy bien (de media, 2 veces su corriente continua).

Producción

¿De dónde viene la energía?

Toda la energía debe generarse antes de que pueda usarla. Victron le permite combinar diferentes opciones. Primero está la alimentación del puerto. Puede estar limitado a unos pocos amperios, pero es “enchufar y usar”. Mientras navega, puede usar un alternador (adicional) en el motor del barco. Los veleros más grandes que la media usan generadores consulte nuestro otro ejemplo. Sin embargo, el ruido arruina el placer de navegar. Por último, puede usar paneles solares para obtener energía de forma gratuita.

Sistema completo

Un examen más detallado

¿Como se traduce el perfil energético en un sistema? Esta es nuestra recomendación para un velero medio.

Batería auxiliar:

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.
