Truck

On the road again.
As comfortable as possible.

When you just can't wait to get on the road again,
seeing things that you may never see again,
you need life on board to be as comfortable as possible.

Who can resist a fresh coffee break or a warm meal served right from your cabin? No wonder there's increased demand of power electronics on board that can power complete ‘kitchen' extensions. Once you are back on the road again, you'll want it all without the hassle. This is why our wide range of user-friendly products are built for the road with professional quality that is driven by 45 years of innovation and problem solving.

So, who can't wait to get on the road, again?

Designed to provide hassle free power.

Built for the road.

Whatever makes your life onboard more comfortable. From charging your laptop to powering a complete mobile kitchen, Victron Energy modular system components allow you to build a complete system, exactly to your specifications and budget. For now, let's assume we're designing a comfortable life on the road, with an onboard microwave (900W) a coffee machine (1000W) laptop charger (80W) and 24V 40W drawer refrigerator.

Daily energy consumption AC

890Wh

Daily energy consumption DC

  • 01

    哪款逆变器(尺寸)是经济高效的解决方案?

    对于那些并非必须有岸上充电的系统来说,为专业用途而开发的Phoenix系列逆变器堪称理想的高性价比解决方案。Pure Sine Wave技术可为电脑等敏感的电子设备充电,高峰值额定功率支持重型工具启动时产生的大电流,因此您可以为任何负载供电,而不会出现任何问题。广泛的Phoenix系列逆变器包含很多型号,因此能够轻松高效地与合适的逆变器匹配,从而满足系统的(峰值)功率要求。
    Inverters convert 24V DC power into 230V AC power. Inverters should be sized to handle the average AC load continuously and should match the expected peak power current of the simultaneous AC loads. See all our inverter/chargers

    The professionals' choice

    Phoenix 24/1200 VE.Direct inverter: the expected 900W continuous power need of the microwave is no match for the 1200VA rated continuous power of the inverter, enough to power a laptop and the coffee machine at the same time (the microwave and coffee machine are not to be used at the same time in this case, to save money on bigger models). This model is large enough to compensate the inverters temperature derating at higher (cabin) temperatures in the summer. The trucks electronics are based on 24V, it is recommended to keep the service battery and inverter at 24V too.
    1. With the optional VE.Direct to Bluetooth Smart dongle, the Phoenix VE.Direct inverter can be configured and monitored with the free VictronConnect App.
    2. Systems with a significantly higher daily energy consumption, or that rely on less ‘engine time' may not be able to rely completely on charging by the engines alternator and may therefore require (overnight) shore power charging, especially when using lead-acid service batteries, where a full charge takes more time than using lithium batteries. This is where the Multiplus Inverter/Charger combination can be a better choice.
  • 02

    Can you use the starter battery for AC power or what service battery do you need?

    The daily power profile of this truck cannot be taken from the starter battery without the risk of running it empty, this is why an additional service battery is required. Victron Energy offers multiple options for the service battery, but the main choice is between lead-acid and lithium which mainly depends on the expectations of the performance, cost-per-cycle and physical aspects (size/weight). The choice in battery technology also leads to different consequences for the other system components that are directly attached to (or manage) the batteries.

    In general, use lithium when the daily power demand is extremely intense, when superfast charging is essential or when there are weight or space limitations. Lithium also has a lower cost per cycle. Lead-acid has a lower up-front cost and is perfect for regular, less demanding power profiles and when weight and space are not an issue. The above probably cuts 45 years of battery development know how a bit short, for more info check our deep dive.

    Victron Energy offers exceptional quality batteries with high performance characteristics that are thoroughly tested. Our datasheets offer a fair picture of the performance and expected life cycles, meaning no investment surprises along the way. Our wide range of batteries
    Choices, choices... Lithium or lead-acid?

    The professionals' choice

    2x 12 Volt Deep Cycle AGM 165Ah. As there are no space or weight restrictions aboard this truck and the loads aren't extremely demanding or used the whole day, day to day, two in series connected 12 Volt Deep Cycle AGM 165Ah batteries can weigh in to power the loads with ease. Lithium would be a better alternative when there are also demanding consumers that are intensely used, but with the higher upfront costs of the battery and the related components, this is not the cheapest option.

    As a rule of thumb for sizing the batteries, we calculate with 2x the daily energy consumption for lead-acid batteries because of their 50% safe discharge capacity and keep roughly 20% in reserve for Lithium batteries. Select the nearest model from our range and round up the amps to be sure.
  • 03

    Safely combining service batteries with (smart) alternators and starter batteries

    Master all the challenges that come your way by combining (smart) alternators, starter and service batteries (lithium or lead-acid) with our wide range of DC-DC chargers, battery combiners or Smart BMS products. Our solutions are specially designed for vehicles and make sure both lead-acid and lithium service batteries can be properly charged, without damaging the smart alternator or the batteries.
    The right solution primarily depends on the combination of your alternator(s) (smart or conventional) and service battery type (lead-acid or lithium), amongst other factors.

    The professionals' choice

    Cyrix-ct 12/24-230. This truck doesn't have a variable voltage (smart) alternator so the Cyrix is a perfect option. This heavy duty relay intelligent battery combiner will prioritize starter battery charging and when it's full, it's relay will allow the 24V service battery to be charged with the charge current that is naturally drawn from the battery bank, up to a max of 230A, which is more than enough. The Cyrix is sized to be larger than the alternators’ maximum output.
    When the truck does have a (variable voltage) smart alternator, a DC-DC charger or in case of Lithium a (Smart) BMS device might be the right option, see datasheets for more info.
  • 04

    Do you need shore power to charge the service battery?

    Although it is unlikely that this particular setup needs shore power, due to the number of daily driving hours of the truck, it's better to be prepared for the worst-case scenario, like being able to charge the starter battery in an emergency.

    The professionals' choice

    Blue Smart IP22 Charger 12/30 (3). A built in Blue Smart IP22 Charger provides a 30 Amps charge current per hour, charging a completely empty battery overnight. The second charge output will also take good care of the starter battery.

How do the system design considerations translate into a robust system?

装载

AC devices (single phase)

Every ‘household’ appliance or ‘heavy duty tool’ you would expect at home or at work can also be found in independent energy systems. All these devices need an Alternating Current (230V or 110V) to run.

Some of these devices such as computers can be sensitive to the quality of the inverted power (bad shore- or generator AC-input power can influence this quality negatively). Motor driven or heat generating equipment may require a high start-up current. All our inverters produce a pure sine wave, even when the AC input quality is less good, ensuring that sensitive loads can be powered and enjoy a peak-power of generally 2x of the inverters rated capacity to power even the heaviest of loads, or basically any load, problem free.

Examples of AC-devices:

  • Heavy duty tools such as a drilling machine or a jigsaw
  • Computers
  • Phone chargers
  • Fridge and freezer
  • Lights
  • Coffee machine
  • Microwave
  • or basically any AC powered device you can think of.

Alternators

Vehicles and boats are equipped with engine(s) that generate the power to move, but also generate electrical energy through alternators. Alternators generate electrical energy with a direct current (DC) from mechanical energy, which is used to store the energy in the battery bank or power DC-equipment directly.

Small engines usually have small alternators, larger engines usually have larger alternators, sometimes they are even equipped with (extra) high-output alternators to increase the output. Vehicles, especially with Euro 4/5 engines, may come with smart (variable voltage) alternators, controlling the output based on vehicle operating conditions. This renders it unsuccessful at charging a secondary battery system to a usable level. Lithium service batteries may put a heavy load on the engine’s alternator, which probably needs to be protected from overheating or early wear.

Whatever your engine’s alternator, or service battery type, Victron Energy offers a wide range of solutions to safely connect any alternator to any battery bank, without damaging the smart alternator or batteries. Please check our datasheets for more information. Also, check your manufacturer's documentation to see what output your alternator can provide. With Lithium service banks and conventional or smart alternators we recommend to calculate with 50% the alternator output spec, to not overload the alternator.

See all our DC-DC chargers See all our Battery Combiners See all our (Smart) BMS options

Battery Combiners

Battery Combiners are used to safely connect the starter battery and service battery in parallel.
The Battery Combiner will allow the service battery to be charged when the engine is running (at a pre-set voltage). The service battery will be disconnected from the starter battery when the voltage decreases below a float level, preventing it from being drained by loads running off the service battery. Victron Energy offers multiple models and sizes of Battery Combiners, it depends on your type of system which is best to select.

Emergency start: in case of start battery failure, some battery combiners allow the engine to be started from the service battery, see datasheets for more info. Project-Id-Version: PO 2834 v1 Report-Msgid-Bugs-To: PO-Revision-Date: Last-Translator: Language-Team: Language: zh_CN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plural-Forms: nplurals=1; plural=0; X-Generator: Poedit 1.7.1

As an alternative to using Battery Combiners, other options may include more control and configuration options, especially to protect non-regulated alternators from overheating and Lithium batteries from excessive (dis)charging. For combining lead-acid batteries, DC-DC chargers can be considered. For Lithium service batteries options include DC-DC chargers, special Lithium Battery Combiners (which can be connected to a BMS) or all-in-one Smart BMS products.

See all our Battery Combiners See our DC-DC chargers See our (smart) BMS options

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

VE.Direct Bluetooth Smart dongle

The VE.Direct to Bluetooth Smart dongle allows you to monitor compatible devices through the free VictronConnect app through a local Bluetooth connection, with information such as battery status, solar panel power and more.

The dongle is able to read data from all products with a VE.Direct port, such as the BMV-70x series battery monitors, Phoenix Inverters with VE.Direct port, MPPT Solar Charge Controllers.

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.

See all our chargers

DC Electronics

DC-equipment is designed to work directly with the power coming out of the battery bank (Direct Current). Especially vehicles and boats can have (a lot of) DC equipment on board (such as control panels, lights, navigation equipment, auto pilot, depth sounders, etc).

Some smaller off-grid systems can solely run on DC, with 12V lights, TV’s or fridges. Larger systems may combine AC and DC consumers.

In any case, it is important to protect the battery against excessive discharge, for this Victron offers the ‘BatteryProtect’.

Inverters

Inverters convert DC power from the batteries to AC power, safely powering any kind of appliance or heavy duty tools with 230V (or 110V in other markets).

All Victron Energy inverters are developed for professional duty and enjoy a reputation of extreme resilience, even in the most demanding conditions. The built-in Pure Sine Wave technology safely powers sensitive electronics such as computers, their high peak power rating allows high start-up currents from heavy duty tools, so you can power any load, problem free. Their high efficiency and ultra low self consumption ensure the stored energy can be used to efficiently power the consumers, instead of having to calculate with wide margins to compensate for energy losses.

Larger models can power industrial appliances and virtually unlimited power can be provided by Parallel or 3-phase operation. Other models come with built-in chargers (Inverter/chargers) which can be used when charging from shore- or generator AC sources is essential. Whatever you need, our wide range makes it easy to select the right inverter for your application, saving you the cost of having to buy a larger one.

See all our inverters See all our inverter/chargers

Service Batteries

The service battery stores power for the system's consumers, providing autonomous power especially for moments when input power sources aren’t (fully) available.

Victron Energy offers several battery technologies, all designed for professional performance, reliability and long service life in the most demanding environments. They come with a 2 year worldwide warranty and our datasheets offer a fair picture of the performance and expected life cycles, meaning no investment surprises along the way.

While there are multiple technologies to choose between, the main choice is between lead-acid and lithium which mainly depends on the expectations of the performance, cost-per-cycle and physical aspects (size/weight).

  • 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

Shore Power

Shore power is used to recharge the batteries and/or run large AC equipment.
Sometimes shore power is less than perfect. You might run into voltage drops, or there could also be power surges, which could harm sensitive equipment on board. Victron Energy inverters smooth out these problems and turn bad power into perfect power.

Often shore power is limited in how much power you can draw, i.e. just 10 Amps, without any higher rated points available. Victron Energy inverter/chargers allow you to set a maximum shore power current and still turn on higher rated equipment without blowing a fuse: thanks to Victron Energy PowerAssist, power from the batteries is added seamlessly to the AC input, automatically bridging the gap between supply and demand.

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.

See all our Battery Monitors

Starter Batteries

Starter batteries are needed to start your engine(s). These batteries are engineered to deal with a large discharge current and enjoy a different technology compared to service batteries. To avoid accidental draining of the starter battery, it should always be isolated from the service batteries. Victron Energy offers multiple solutions for different system types.

Victron Energy offers several Battery Combiners. More comprehensive ways to safely connect the starter- and service battery are also available, including connecting a Battery Combiner to a BMS, all-in-one Smart BMS products or DC-DC chargers. These options may offer more control and configuration options, especially to protect non-regulated alternators from overheating and Lithium batteries from excessive (dis)charging.

See all our Battery Combiners See all our DC-DC chargers See all our (Smart) BMS options

VictronConnect

All Victron Energy smart products 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 the performance data of your system. You can also easily change settings, turn devices on or off and much more.

Non-smart devices with a VE.Direct port can also become smart, through the use of the VE.Direct Bluetooth Smart dongle

It is also possible to monitor and control your system remotely. VictronConnect-Remote functionality enables Victron products with a VE.Direct interface to be accessed remotely through a GX product, via the VRM online portal. This powerful feature allows full product configuration and monitoring from practically anywhere in the world using the VictronConnect app. The user interface experience is just like the products were connected locally using Bluetooth or a wired VE.Direct to USB interface.
