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?
The daily energy consumption is calculated by adding up the sum of all consumers X how much time they will be used in a day. Add all the Watts of the simultaneously used consumers to calculate the required peak power.
Find below some of the main design considerations explained, click on the questions for our engineers' recommendations.
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.
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.
How do the system design considerations translate into a robust system?
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:
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 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.
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.
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.
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.
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-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 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
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).
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.
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.
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
