Pravi magični trenutek je spraviti čoln s prikolice in se pognati v vodo. Ne glede, ali greste na ribolov, deskanje na vodi ali na kratka potovanja z otoka na otok za nekaj dni, jadranje pomeni svobodo. Enako želite občutiti, ko gre za električno energijo. Svoboda, ko polnite svoj telefon in ko predvajate svojo najljubšo pesem, kjerkoli se nahajate. Victronova pametna energetska rešitev zagotavlja to svobodo za vsak majhen čoln.
Predstavljajte si, da gresta čez vikend na ribolov s prijateljem. Izvenkrmni motor popelje vaš majhen čoln na sredino jezera. Ulov dneva bo večerja, ki jo boste pripravili, preden boste za eno noč kampirali na majhnem otoku.
Razmislite o optimalnem energetskem načrtu , ki vam bo pri potovanju pomagal uživati v udobju.
Celo pri majhnem čolnu se moramo zanašati na električno opremo. Vse, kar je opremljeno v čolnu bo delovalo na enosmerni tok, vendar pa boste želeli imeti za polnjenje telefona ali prenosnika izmenični tok. Za polnjenje vseh električnih stvari potrebujemo določeno količino vatov. Če dodamo vse vate, smo le na pol poti. Čas je prav tako pomemben. Na krovu boste morda porabili 100 vatov za luči, vendar so omejeni le za nekaj časa. Majhna hladilna torba bo porabila 50 vatov, vendar bo priklopljena ves čas.
Za inspirativne namene smo opisali 2 sistemska primera na osnovi ‘normalne’ in ‘težje’ uporabe.

Luči bodo morda porabile 100 W na uro, vendar so prižgane le za 4 ure na dan.
100 W x 4 ure = 0,4 kWh / dan
Hladilna torba porabi 50 W na uro, vendar je priključna cel dan (pravzaprav hladi ½ dneva).
50 W x 24 ur/2 = 0,6 kWh / dan
Motorja ne želite imeti prižganega ves čas. Prestrašil bo ribe. Rešitev je shranjevanje energije v (osrednji) akumulator, iz katerega inverter pretvori shranjeno energijo v 230 V. Akumulator lahko spotoma napolnimo z električno energijo z obrežja in alternatorja. Če se na potovanje odpravljate zadnje dni, se prepričajte, da bo imel akumulator načeloma dovolj zmogljivosti, da vzdrži 48 ur.
Zmogljivost shranjevanja litijevega akumulatorja mora biti dvakrat večja od dnevne porabe električne energije.
Zaradi ±50 % manjše zmogljivosti praznjenja, mora biti zmogljivost shranjevanja svinčeno-kislinskega akumulatorja štiri krat večja od dnevne porabe električne energije.
Inverter naj bo tako velik, da lahko neprekinjeno prenese povprečno obremenitev in mora ustrezati pričakovanemu toku konične moči obremenitve, pri čemer naši inverterji zelo dobro delujejo (v povprečju 2 x njihovega neprekinjenega toka).

Kako se vidik električne energije prenese v sistem?
Devices you bring on board usually need an AC outlet. Think of:
As the name suggests: the battery charger recharges the boat’s battery when plugged into shore power. At the same time the Victron battery chargers will also power the boat’s electrics.
All Victron battery chargers operate automatically. You can safely keep them connected to the battery all the time, even when the boat is not in use. Waterproof chargers are also available.
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.

Monitor akumulatorja je kot "merilec goriva" za vaš akumulator. Zapisuje, koliko električne energije se porabi in napolni. Monitor akumulatorja izračuna stanje napolnjenosti, preostalo zasedenost in čas do praznjenja. Napetost akumulatorja ne daje točne navedbe o tem, kako poln je akumulator (še posebej ne pod obremenitvijo). Monitor akumulatorja to daje.
Monitorji akumulatorjev Victron Energy spremljajo pretekle podatke, kot je število ciklov polnjenja, najgloblje praznjenje, najvišja napetost, najnižja napetost in tako dalje. Opozoril vas bo na kritične pogoje, kot so nizka napetost ali nizka napolnjenost in lahko celo izklopi celotno oskrbo z električno energijo, da bi se izognili dragim poškodbam akumulatorja ali zagonu generatorja.
Victron nudi monitorje za akumulator z ali brez zaslona, različice Smart omogočajo spremljanje podrobnih podatkov in prilagajanje nastavitev v naši brezplačni aplikaciji VictronConnect.
Večina litijevih sistemov potrebuje sistem za upravljanje akumulatorjev, ki lahko dovaja informacije o akumulatorju širšemu sistemu. Na tej poti lahko postane monitor akumulatorja odvečen. Za več informacij si oglejte sistem za upravljanje akumulatorjev. Oglejte si vse naše monitorje akumulatorja
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.
Zaščita akumulatorja Battery Protect odklopi nebistvene obremenitve z akumulatorja preden je pod vnaprej nastavljeno ravnijo (popolna izpraznitev bi poškodovala akumulator) ali preden se toliko izprazni, da ne more več zagnati motorja.
Tu lahko izveste še več o zaščiti akumulatorja BatteryProtect Victron Energy. Vgrajene zakasnitve izklopa zagotavljajo, da se ključna elektronika ne izklopi pomotoma, tj. ko zagon motorja povzroči kratek padec napetosti. Prav tako bo samodejno znova povezala vse, ko bo akumulator dovolj napolnjen.
Zaščita akumulatorja BatteryProtect ima daljinsko stikalo, zato se lahko vklopi/izklopi prek BMS ali stikala. Pametna različica je programirljiva prek aplikacije VictronConnect.
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.

Small motor boats rely on their engine to get the job done. Their engine comes with an alternator to charge the engine batteries, drive fuel pumps, etc.
Once the starter batteries are recharged, the engines can also recharge the house battery and power the boats electronics. When the engine is used the majority of the day, there will always be enough energy generation to compensate the daily consumption. However, when the boat isn’t used over time, batteries might run dead eventually. Our battery chargers take excellent care of your batteries when in the harbour or garage.
A small boat will have several electronic devices; they all run of the house battery. Think of:
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.

The house battery supplies power to your boat’s electrical system. Choose a battery with a generous capacity as there might be long intervals between re-charges. Sometimes the starter battery doubles up as the house battery. If you opt for this set-up, make sure the battery is well protected against discharge. It will be hard to start the boat when the battery is flat.
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:

An inverter creates AC power from a DC source. It lets you use devices on board that need a regular AC outlet.
The inverter needs to be big enough to handle the maximum AC load you want to bring on board. If the load exceeds 375 VA, you might consider a combined inverter/charger instead. Models start at 500 VA.
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 starter battery from all other electrical circuits on board, so it cannot be accidentally drained of power, with a BatteryCombiner.
Either in the marina or back home you’ll hook the boats charger up to shore power to recharge the battery. Shore power can also be used for maintenance and to run large AC loads.
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 indicators like battery voltage and current. You can also turn devices on or off, as well as change their settings.
