Majhen čoln

Neizmeren užitek jadranja

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.

Optimalen energetski načrt

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.

Poraba

Koliko potrebuješ?

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.

0.6 - 1.2 kWh / dan

Primer 1

Luči bodo morda porabile 100 W na uro, vendar so prižgane le za 4 ure na dan.
100 W x 4ure = 0.4 kWh / dan

Primer 2

Hladilna torba porabi 50 W na uro, vendar je priključna cel dan (pravzaprav hladi ½ dneva).
50 W x 24ur/2 = 0,6 kWh / dan

Shranjevanje & conversion

Koliko energije je potrebno shraniti?

Motorja ne želite imeti prižganega ves čas. Prestrašil bo ribe. Rešitev je shranjevanje energije v (osrednji) akumulator, iz katerega pretvornik pretvori shranjeno energijo v 230V. Akumulator lahko spotoma napolnimo z 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.

x 2

Zmogljivost shranjevanja litijevega akumulatorja mora biti dvakrat večja od dnevne porabe električne energije.

x 4

Zaradi ± 50% manjše zmogljivosti praznjenja, mora biti zmogljivost shranjevanja svinčeno-kislinskega akumulatorja štiri krat večja od dnevne porabe električne energije.

Pretvorba

Pretvornik naj bo tako velik, da lahko neprekinjeno prenese povprečno obremenitev in mora ustrezati pričakovanemu toku konične moči obremenitve, pri čemer naši pretvorniki zelo dobro delujejo (v povprečju 2 x njihovega neprekinjenega toka).

Proizvodnja

Od kod prihaja energija?

Na voljo imate nekaj možnosti za proizvajanje energije, ki jo potrebujete za potovanje. Prvič, v pristanišču je električna energija z obrežja. Ali - če svoj čoln peljete domov na prikolici - ga priključite v garaži. Na vodi lahko uporabite alternator na motorju čolna.

Kako se profil električne energije prenese v sistem? Tukaj je naše priporočilo za povprečen majhen čoln.

Osrednji akumulator:

Obremenitev

AC devices

Devices you bring on board usually need an AC outlet. Think of:

  • Phone charger
  • Laptop
  • Drone batteries

Battery charger

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 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.

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. Built-in shutdown delays ensure vital electronics aren’t disconnected in error, i.e. when starting the engine causes a short drop in voltage.

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.

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 engines

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.

Boat Electronics

A small boat will have several electronic devices; they all run of the house battery. Think of:

  • Boat control panel
  • Log/depth sounder
  • Chart-plotter or GPS
  • VHF Radio
  • Navigation lights
  • Pump – Bilge, deck wash
  • Fridge
  • Interior lighting
  • Music player
  • Bait Tank – Recirculating
  • Electric Fishing Reels/winches

House battery

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:

  • 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

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.

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 starter battery from all other electrical circuits on board, so it cannot be accidentally drained of power, with a BatteryCombiner.

Shore Power

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.

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 indicators like battery voltage and current. You can also turn devices on or off, as well as change their settings.
