摩托游艇堪称设计杰作。 在游艇的有限空间里,实现了家的舒适感。 不论去向何方,您都渴望享受来之不易的极端奢华。 Victron提供智能电网,能够应对您航海过程中遇到的任何挑战。 因此您可以悠闲地躺在甲板的椅子上。
不论是携全家前往海岛欢度周末,或是停留在一个美丽的海湾长达一周,您都可以尽情地享受假期。 这意味着最佳电力方案会因游艇和船主需求而异。 无论您制定了哪种航行计划,Victron几乎都能为您的用电需求提供保障。下面我们以“普通” 摩托游艇为例,向您介绍“正常”和“较大”电力情况。
让我们看看您的最佳电力方案,让您可以自由使用电器。
如果没有电气设备,摩托游艇就不可能完整。 游艇运行的大部分设备利用直流电,大型(家用)电器利用交流电。 这能增加多少电力?不要只看瓦数。 微波炉的功率为1000瓦,但只用4分钟。 冰箱/冰柜组合的功率只有100瓦,但一天24小时都在运行。
为了让您清楚明白,根据“正常”用电和“较大”用电,我们简述了两个系统示例。
微波炉的功率为1000瓦,但只用4分钟。
1000瓦/ 60 x 4 = 0.67千瓦时/天
冰箱/冰柜组合的功率为84瓦,但一整天都在运行(通常制冷时间为半天)。
84瓦x 24小时/2 = 1千瓦时/天
摩托游艇需要完善的电力存储,并转换为230V。利用发动机给电池组发电意味着,您在远离岸边抛锚过夜时,无需打开嘈杂的发电机。由于您可能会原地逗留几天,深循环电池应该有足够的电量。根据经验,我们计算的结果是,没有岸电/发动机/发电机/太阳能,船上电力可维持48小时。
锂电池的强大容量应该是每日用电量的两倍。
由于± 50%的较小放电容量,铅酸电池的存储容量应为每日用电量的四倍。
逆变器应能连续处理平均负载,并与预期的峰值电流相匹配,我们的逆变器处理得非常好(平均为其连续电流的两倍)。
正常和较大 以千瓦时计算的电力情况,基于每日用电情况,应与发电量保持平衡。
以安时计算的蓄电电池,利用铅酸电池,容量翻倍。
How do the system design considerations translate into a robust system?
Everything you would expect in a home can also be found on a motor cruiser. All these devices need AC to run. Think of:
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 DC-DC converter or Buck-Boost.
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 SystemsDischarging 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.
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
Keeping grips on all the systems on board can be a hassle. The solution: tie everything together in a single boat network using NMEA communication standards. Your boat network can include navigation equipment, tank senders, battery monitoring and much more. The status information can trigger alarms and shutdowns, adding to the safety on board. The Cerbo GX now supports the NMEA2000 out protocol, allowing you to monitor your boat’s network of systems from wherever you are.
Motor cruisers have one or two diesel engines to get from harbour to horizon. The engines are designed to run continuously, for days on end. They also come with high-output 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 motor cruiser 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.
A motor cruiser is packed with dozens of electrical devices. These are all connected to the house battery. Think of:
The Buck-Boost converter is used in dual battery systems, where the (smart) alternator and the start battery are used to charge the service battery (of equal or different voltages). The Buck-boost can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries.
Charging lithium batteries from the alternator
Alternators cannot be connected directly to most lithium batteries. A lithium battery will draw more current than the alternator can supply, which may result in alternator damage. A Buck-Boost DC/DC converter solves this problem: it acts as a current limiter between the alternator and the battery.
How to select a Buck-Boost? The current rating of the DC/DC converter has to be less than the alternator’s current rating. For example: pair a 50 Amps converter with a 60 Amps alternator. In the software the ideal throughput can be defined.
When the charging capacity exceeds the limits of the Buck-Boost, consider working with DC-DC generator(s) sized to the capacity of the battery bank.
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.
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.
The generator provides energy when shore power is not available and the boat’s engines aren’t running (or can’t supply enough power to meet the demand). The generator is usually supplemented with a inverter/charger and a battery bank. The batteries act as a backup and allow for quiet periods at night.
Thanks to Victron’s PowerAssist, the generator doesn’t have to be sized for the maximum load. You can use a smaller generator which is cheaper to install, uses less fuel and produces less noise. The inverter automatically bridges the potential gap between supply and demand with support of the battery bank.
A GX 4G module will add mobile internet connectivity to your Victron Energy system. When your system is in range of a 4G network, it will send data to the VRM website and you can monitor the system from your smartphone. The module adds GPS tracking, recording your trips and putting up a geo-fence around the installation. You will get an alert via mail when the system travels outside the geo-fence area.
Victron Energy offers multiple 4G modules and the Global Link 520 modem, which operates without any monthly fees or subscriptions, for the first five years and several 4G modules. See our 4G Modems See our Global Link 520
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.
The Victron Energy Cerbo GX is the communication-centre of your systems installation, allowing you to always have perfect control from wherever you are and maximises its performance. The optional GX Touch 50 is a companion to the Cerbo GX, it’s five inch touch screen display gives an instant overview of your system and allows you to adjust settings in the blink of an eye.

The house battery stores power for the boat’s electrical system. Motor cruisers typically have large power demands 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:

On motor cruisers you’ll need an intelligent inverter/charger that automatically switches between various sources to cater for all power needs.
In the marina shore power will be used to feed the boat’s AC grid and charge the batteries. When no shore power is available, the batteries will power both the DC and the AC grid. Power can be drawn from the boat’s engines while sailing. If the power demand gets too high or the batteries get low, the generator will kick in to power the load and charge the batteries.
Thanks to PowerAssist, the generator doesn’t have to be sized for the maximum load. You can use a smaller generator which is cheaper to install, uses less fuel and produces less noise.
If you don’t have a generator on board, a Multiplus is all you need. With a generator on board a Quattro is the better choice.
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 motor cruiser. If your boat’s system is based on 12 Volts, select a 12 Volts unit instead. If you have dissimilar battery banks, consider charging them using a DC-DC converter, or have it power several dissimilar appliances with a different voltage than the house battery.
Generally speaking, a 3 kVA unit will be big enough, unless the power consumption is higher than average. For example: when you have an air conditioner on board. If this is the case, choose a 5 kVA unit.
The Victron integration between our GX range and several leading Multi Functional Display manufacturer brands enables you to easily connect an MDF to the heart of your power system such as the Cerbo GX, or the GX enabled MultiPlus-II GX. Once connected you can easily monitor and control your boat’s power system, right on your Glass Bridge.
Usually shore power is available in the marina; it is used to run large AC equipment on board and recharge the batteries. Larger boats need a three phase supply. Sometimes shore power can’t provide enough power to cater for the total AC load of the boat. It might also just be single phase.
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. Thanks to Victron’s PowerAssist, the generator and batteries can automatically bridge the gap between supply and demand.
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 panels won’t be able to cover all the power needed, but they can reduce the running time of the generator and fuel costs.
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.
See our Solar Calculator to size the solar panels and select a MPPT chargerSolar panels won’t be able to cover all the power needed, but they can reduce the running time of the generator and fuel costs. Victron offers a wide range of highly efficient solar panels that are just perfect for marine use.
The starter battery is needed to start your boat’s engines. These batteries are different from house batteries and engineered to deal with a large discharge current. The starter batteries should be ready to go. Always use a BatteryCombiner to connect the starter batteries to the rest of the electrical system; it prevents an accidental drain of power.
The GX Touch 50 display allows you to have an instant overview of your system and adjust settings in the blink of an eye. Simply connected to the Cerbo GX with one cable, its super slim 5 inch waterproof design and its top-mountable setup bring a lot of flexibility when creating a crisp and clean dashboard.
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.
See what the VictronConnect app can doThe Lynx Distributor is a modular DC busbar, with locations for four DC fuses. It will monitor the status of each fuse, and indicate its condition with a LED on the front. When connected to a Lynx Smart BMS or Lynx Shunt, the status of the fuses will be visible in VictronConnect and VRM (when the Lynx Smart BMS is connected to a GX-device).
Multiple Lynx Distributors can be used to connect all the DC-loads and charge sources on one side of the BMS, on the other side, a Lynx Power In (without fuses) or another Lynx Distributor (with fuses) can be used to connect the battery bank to the modular busbar.

This product is part of the modular Lynx busbar system that also provides the Lynx Smart BMS, a dedicated Battery Management System for Victron Lithium Smart Batteries (for non Victron Lithium batteries, use the Lynx Shunt).
See all Lynx modulesMonitor and manage your Victron Energy systems from anywhere and catch potential issues early by setting alerts and alarms. With VRM you are always in perfect control from wherever you are.
VRM works with a GX-device such as the Cerbo GX with internet connection, the GlobalLink 520 or GSM LTE 4-g for smaller systems.
Monitor the battery state of charge, power consumption, power harvest from solar, generator and mains in real-time. Optimise the energy harvest and usage with history graphs and detailed analytical reports. Catch potential issues early by setting alerts and follow up on alarms to prevent definitive system failure.
Easily control the shore power input current limit, switch on the inverter, (auto)start/stop generators or even set quiet periods to avoid starting the generator in the middle of the night. With VRM you can change any setting, follow up on alarms, perform diagnostic checks and resolve challenges from wherever you are.
See all our GX-devicesThe Lynx Smart BMS is a dedicated Battery Management System for Victron Lithium Smart Batteries (for non Victron Lithium batteries, see below). There are multiple BMS-es available for our Smart Lithium series of batteries, and the Lynx Smart is the most feature rich and complete option. Its main features are:
The dedicated battery management system (BMS) protects Victron Lithium Smart batteries against deep discharges, overcharging and high temperatures. 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.
Battery monitoring is built into the Lynx Smart BMS; no separate battery monitor is needed. With Bluetooth the battery bank can be monitored with VictronConnect, when connected to a GX-device, also with VRM, our remote monitoring solution.
This product is part of the modular Lynx busbar system that also provides the Lynx Distributor which is a modular DC busbar containing 4 DC fuses and monitors their status in VictronConnect and VRM and other DC connections to handle distribution, fusing, battery monitoring and/or Lithium battery management.
The Lynx busbar system can also be used for DC distribution and monitoring of non-Victron Lithium batteries. In that case, replace the Lynx Smart BMS with the Lynx Shunt VE.Can for monitoring of any other battery. See all Lynx modules
