Probleme de charge via Orion DCDC


J'ai récemment remplacé mon parc servitude plomb sur mon voilier par une batterie lithium 200Ah. Un chargeur DC DC Orion 30A de Victron est branché entre la batterie moteur (plomb) et la servitude (lithium) pour assurer la charge de cette dernière aux bons voltages. Quand le moteur tourne, le régulateur charge la batterie moteur, ce qui est détecté par l'Orion (tension batterie moteur > tension Vstart) et enclenche la charge de la batterie lithium. Jusqu'ici tout fonctionne. En revenche, j'ai remarqué que l'Orion ne faisait rien quand le bateau était branché au quai (moteur éteint) et que le chargeur de quai rechargait la batterie moteur. J'imaginais naïvement que la charge de la batterie moteur serait détectée automatiquement par l'Orion et qu'il commencerait à charger la batterie lithium. Quelqu'un comprend-il pourquoi ce n'est pas le cas ?

Buck-Boost 50A/100A CAN-Bus communication

We would like to communicate with our Victron Buck-Boost Converter 100A, to read out some internal values. First off all we need any connection pin layout pf the RJ10/4PC4 vonnector, there is nothing in the manual. Does the protocol follow the VE.CAN or NMEA200 protocol?

Regards, Peter

What type of connector is used for the remote on a Victron Orion DC-DC Charger?

I need a replacement remote bridge for my Orion. Does anyone know what type of connector it uses or where can I source one?

Victron Energy Orion-TR 24|12-20 DC-DC Converter as start battery charger

I am connecting a Victron Energy Orion-TR 24|12-20 DC-DC Converter to my Multiplus 24/3000 trickle charger spade outlet to charge my 12 volt starter battery. I am planning to use relay 2 as a switch to turn the converter on and off. Is there anything I should be aware of or avoid in making this connection?

Orion 24/12 70amp charging my 12 lead acid


I have very large 24v lifepo4 house bank on my boat, and I also have 2x Orion 24/12 70a in parallell to give my boat 12v. Now I want to connect that (in a very safe way) to trickle charge my normal lead acid start batteries.
Can I just connect them directly, or should I make sure they're only trickle charge in some way? How? I'm thinking I should be able to charge them directly, and once they're are topped up, they will just stop taking more charge, or is this wrong and I will overcharge them and blow them up? (I'm not gonna connect them when empty, since that will charge too fast, as they are only 80ah each).

Orion 24/12 70 amp


I have a 24v Victron lithium setup and have 12v loads. I am using an Orion 24/12 70 dc converter and wondering if you need a battery protect or can use the BMS load disconnect to turn off the Orion directly.

Orion-Tr DC-DC Converter Isolated 12/12 18A can't set output voltage

Installed the converter in my travel trailer. Input connected to tow vehicle 7-pin connector and my dvm reading on the input to the converter i 14.2 volts with the vehicle running. Want to adjust the output voltage to 14.4 for my Lithium house batteries. When I connect my Digital voltmeter to the output, however, the reading jumps all around. No steady output voltage reading. No load on the converter, no battery connected to output. Is the unit defective or am I doing something wrong? Thanks for your help!

24/12 for starter battery top-up

Hi all,

I have a small fishing boat with the house load (12V at average load about 2-3A) supplied by the starter battery (conventional, not lithium). There is a separate 24V circuit (2 x 12V 100Ah lithium in series) to run the electric trolling motor. To reduce the risk of the starter battery charge getting run down by the house load, I'm planning to add a 24/12-9A Isolated Dc-Dc Converter to keep the starter battery topped up. In effect the house load will be supplied from the 24V system via the converter. I can protect the starter battery without the need for a dedicated 12V house battery.

Sketch of proposed setup below.


  1. Do I need the to fuse the input and output of the 24/12 converter? (am thinking only on output, since input is already fused)
  2. Does the converter need to be turned off before starting the outboard? (I assume not)
  3. Will the outboard alternator and the 24/12 converter play nicely with each other? (I assume yes)
  4. Optimum output voltage to set the converter output (I was thinking around "float" voltage i.e. 13-13.5V)

Thanks in advance.

Victron Orion 24/12 12V Power Feedback when isolated.

I have a 24V circuit charging a 12V battery which works fine. But If I isolate the 24V circuit power supply, the input side of the Orion (and the rest of the 24V circuit) becomes powered from the 12V battery. The 24V and 12V circuits have a common ground.

Is this behaviour normal? How do I prevent it?

Voltage level for remote On/off input on Orion-Tr 48/12


I have a 48V battery system which is charged with a SmartSolar 100/20 MPPT. A Orion-TR 48/12 is used to step-down to 12V.

I would like to use the "Load" output on the Smartsolar to control the Remote on/off on the Orion-Tr, because the "Load" output is only rated to 1A @48V.

However, the ratings of the remote on/off input on the Orion-TR are not specified anywhere.

Is the remote on/off input usable with a 48V signal?

Thank you!

Buck Boost cutoff for lithium batteries

I see this question has been asked many times but no clear answer.

What is the best way to set up a Buck boost to charge a lithium battery bank, but shut off charging to protect the batteries? Or does it need to shut off? What happens when the batteries reach the preset charge voltage of the Buck boost? Will it just keep charging at its full current?

Our setup is on a Ford Transit van, Buck Boost 50a charging a 824ah SOK battery bank, with Smartshunt and CCGX. We’ve set the charge voltage to SOK parameters, but I’m concerned about overcharging the batteries.

What is the easiest/best way to trigger the on/off relay on the Buck boost to stop charging when the batteries get to a certain voltage?

Orion DC DC Charger - when will it be networkable?

Hi All, I have a camper that runs solar on the roof, and via a Smart DC DC Orion 24/24 - 17 charger in my truck camper. Currently these are not networked as I am driving along which does cause them to sometimes be in different charging states.

Posts on here have asked the question but have not been updated recently - when will the Orion DC DC chargers join the Victron Networked family?

I am very keen to have all devices working on the same charging algorithm. Is there a workaround with the Victron Dongle?

Does anyone know when these will be networkable?

How to measure two DC Inputs On CCGX

I am looking to install a Victron system on my RV that will be using a third-party DC-DC charger to charge 48v house batteries from the vehicle's 12v alternator. If I were to connect this charger through a dedicated BMV battery monitor (with a second one for the system's DC loads), is there any way to have one show up as an "alternator" input on the CCGX display screen?

I know I could connect it through the BMV-700 and presumably just have the CCGX show it as power flowing from the "DC loads" box to the battery. My primary concern is ease-of-use for the end user, so I would greatly appreciate any way to configure thte CCGX for this display.

Orion-Tr 48/12-9A Has the hardware or firmware changed?

I bought an Orion-Tr 48/12-9A (SN: HQ2113GTR6C) along with a Victron Multiplus, Cerbo etc to create an initial prototype prior to going into production with it all on a product we will produce using them. The DC to DC Orion is to supply power to a 12.8V 22AH LiFePO4 battery to act as a back up for the comms systems if the main batteries get low/shutdown. The main batteries are a 48 volt system on LiFePO4 and hence the Orion.

I've been testing the Orion to do this for the last 4 months and it has worked perfectly, it recovers the over discharged LiFePO4 if that ever happens and recharges it to my trimmed voltage limit set on the Orion, current tails off to nothing from a steady 9A and it supports the loads while their is available main batteries.

However I then bought six more units (SN: HQ2126K3QQ9) for pre production of our systems and they are not working the same, if you play with connecting and disconnecting then reconnecting the output it does work but the current shoots up from the 9A it should be limited to, to up to 15 amps sometimes. If I fit a diode in line the problem almost cures where it prevents the DC to DC seeing the battery as it were so current flows normally, however it is still putting out more than 9A according to my DC clamp meter.

How do I get stock of the right DC to DC converters that were working perfectly?

I note the instructions say not to be used as a battery charger but your web information here shows use doing exactly that:Booklet-Off-Grid-System-EN.pdf (victronenergy.com)
