Shorted remote pins kills Orion 24/12-70?

My Orion 24/12-70 turns on/off via a simple 3-pin lighted switch — which were connected to left side remote pin, right side remote pin, and ground /truck chasis (which is needed for the tiny LED in the switch to light on). Not connected to any additional power source.

The LED in the switch stopped working and I attempted to replace with identical 3-pin lighted switch, and I must have inadvertently shorted one of the remote pins to ground. The Orion now will not turn on when I jumped the switch. And There’s no voltage from either of the remote on/off pins. Any ways to reset/salvage my 24/12-70?

TS400-25 Buck Boost minimum value for Output Current?

on my ts 400-25 it is not possible to set the maximum output current lower than 8A.

if i try to setup 1A or 7A, the program resets the value back to 8A after pressing "send all settings to converter" - same in pt 31 charge protection current limit, only 8A or higer possible.

what is the minimum current settable?

unit is new, 1 week old, the serial number is 3714

Buck Boost CAN Bus - is it ONLY used for temperature sensor input?

The Buck Boost has a CAN bus input. It is a single RJ45 connector. Is that purely for a CAN bus temperature sensor or can a Lynx Smart BMS control the device through this port?

Charging a 44.4v battery from a 67v battery with Orion DC-DC


I have a 2kwh 67v lithium battery which I want to use as an emergency backup to charge the main 44v battery that will run my pod drive.

At first glance it seems I could use

Orion-Tr DC-DC converters isolated

but then I noticed on the data sheet the following

Adjustable output voltage
Not intended for battery charging.

Please consider using an Orion-Tr Smart for battery charging.

There doesn’t seem to be an option that would cover that voltage in the Orion-Tr Smart range.

It seems that I can set the output outage to a suitable setting and even the nominal output voltage of 48.2 is perfect so is there any reason this is a bad idea or wouldn’t work for me ?

Again I stress it’s an emergency backup for a bit of extra range, I have several of these batteries I have no use for and I can fit 2 of them in a place on my small boat which is free and I have no further space for another 44v battery which is a much larger format.

Any advice appreciated.

Edit: I’ve since come across this page

PDF of dc-dc converter

Which seems to be the same product and states the following so no I’m really confused

Adjustable output voltage: can also be used as a battery charger

Victron 12

Hallo, ich habe einen Victron Energy Orion-Tr IP43 12/12-9Volt erworben.

Laut Handbuch kann man diesen verwenden um eine Batterie mit Erhaltungsladung zu laden.

Ich habe eine Starterbatterie und möchte, bei laufendem Motor, eine LiFePo4 Batterie vorsichtig laden, wenn die Spannung niedrig ist.Ich habe einen Ladebooster der versucht über 30A einzuspeisen.Das BMS der LiFePo4 schaltet dann aber ab.Es ist dem BMS zu viel.Mit meinem Solarladeregler funktioniert es, aber halt nur tagsüber. Nachts habe ich keine Möglichkeit.

Ich habe den Viktron angeschlossen den Ladeboooster abgeklemmt.An den Klemmen des Orion Tr habe ich an den Inputklemmen (bei laufendem Motor)14,2V an den Outputklemmen 12,8V. Es fließt aber kein Strom. Den Spannungs-Drehregler habe ich schon auf Maximum gedreht.

Meine Frage ist, ist der Spannungsunterschied bei diesen Spannungen zu niedrig und deshalb fließt kein Strom oder könnte es sein, dass die intelligente Lichtmaschine (Citroën Jumper Bj.2018) dies verhindert.

How to setup multiple chargers connecting simultaneously.


I have purchased the following devices and I am starting to setup the system on my Boat, where I have a Starter Battery and a House Battery:

  • Blue Power Charger 12 30 3
  • Smart solar MPPT 100 30
  • Orion-TR Smart 12 12 - 30
  • Smart Battery Protect 12/24 100
  • BMV-712 Smart
  • 2 x Victron 12V 175W Mono Solar Panels

My question relates to situation in which these devices will all be working at the same time.

The AC/DC and DC/DC Charger, will rarely do that, as I will either be on Shore Power or on Engine Power, but there could be very rare instances of the engines being run while on the dock for a few minutes when also still connected on Shore power.

My main concern is the MPPT Solar Charger running at the same time as the DC/DC Charger when under way and in daylight. But technically, if I am in the situation described above at the dock, all three chargers could be working at the same time, for some short period of time.

Can this damage the devices or the Battery? At present the Battery is a AGM 100Ah Deep Cycle but I will soon be replacing it with a LiFePO4.

Can someone please recommend the best way to setup this system? Am I better off switching manually things on off based on the usage? Or can I setup the devices parameters in such a way that they will automatically stop working at the right time based on the voltage produced by other devices?

I would appreciate some guidance and help.

Thank you in advance,

Orion IP67 DC DC Converter 12/24-50A Cables

Hello all thanks for your valuable forum information.

I have exhausted my searching and thought I would ask here, so please forgive me in advance.

I am in the process of installing a power solution on my boat to run a 24V trolling motor via a paralleled pair of 12V 100Ah lithium batteries, using an Orion IP67 12/24-50A DC DC converter to obtain the 24V to run the motor. The document only states the fuse size (120A) and the unit has M6 bolts for DC connections. I am unsure of the cable size that I require to connect the converter input side from the battery bank. I am running 2 AWG (35mm2) between the batteries and a shunt and would figure to continue 2 AWG to the converter (that's my question). When I use the Victron Tool Kit I'm not sure if I should be using 12V or 24V and 100A or 200A with the combined battery output and will the voltage drop be any issue with this size cable. The cable length would be no more than 1m from the bank to the converter. Thanks again.

Orion-TR 12/12-9A as charger output doesnt goes up until batterie ist disconnected (several hundred pieces)


i hope you can help me.

We bought several hundred Orion-TR 12/12-9A for a large project in order to be able to charge LiFePO4 batteries (Jubatec with BMS) (12.8V / 6AH) on the vehicle on-board network in a galvanically isolated manner.

The prototype with an Orion-TR12/12-9A, which was delivered in mid-2021, worked very well, but the devices from the final large delivery from late 2021-early 2022 only ramp up their output after applying the input voltage when the battery the output has been briefly disconnected even though the output LED is green. Apparently the device can no longer cope with the external voltage of the battery. The set output voltage of the Orion is irrelevant. We have noticed that the new shipment now has E4 10R-064720 approval, which the prototype device does not have. Maybe there is a connection here?

SN of one of the non-functioning devices: HQ2136QDPPQ.

Working prototype SN: HQ2107RLXXG.

The batteries have already been tested, that's not the reason.

We now have several hundred Orion-TR12/12-9A, which are not suitable for their purpose.

Anyone an idea? Victron support?

Autarker Wohnwagen mit Victron Smart BatteryProtect 12V/24V-65A und Victron Orion-Tr 12/12-9A

Hallo Victron Community,

ich möchte mit den beiden Victron Komponenten Victron Smart BatteryProtect 12V/24V-65A und Victron Orion-Tr 12/12-9A inklusive einer 100 Ah LiFePo4 eine „Autark-Konfiguration“ in meinem Wohnwagen realisieren – siehe Foto

Die 100 Ah LiFePo4 Batterie soll bei der Fahrt über die Lima das Zugfahrzeugs geladen werden, der Smart BatteryProtect soll eine Entladung der Batterie des Zugfahrzeugs im angekoppelten Zustand verhindern.


Nachdem alles installiert und verkabelt wurde, ist mir beim Smart BatteryProtect aufgefallen, dass dieser weder am Ein- noch am Ausgang die Spannung anzeigt, welche vom Fahrzeug mit ca. 15 Volt über das 13-polige Kabel der AHK kommt. Komischerweise werden die 15 Volt aber in der Victron App angezeigt und auch am Eingang des Victron Orion-Tr kommen offenbar auch 15 Volt an – siehe Fotos.

Die Ladespannung habe ich für den LiFePo4 Akku auf ca. 14,4 Volt über den Potentiometer am Victron Orion-Tr 12/12-9A eingestellt.

Könnt ihr mir sagen, warum am Ein- und Ausgang des Smart BatteryProtect nur ca. 11,7 Volt gemessen werden können?

Habe ich vielleicht etwas falsch konfiguriert? Die blaue LED am Smart BatteryProtect blinkt, wenn die AHK angeschlossen ist.







Für Eure Hilfe bedanke ich mich im Voraus.

Orion TR Smart and Euro 6 Engines

Hi the collective hive of information.

I am in the middle of commissioning an Orion TR Smart 12/12-30A on a VW T6 Camper van. The system doesn't seem to be triggering that often, and even after a couple of hours driving the Lithium batteries are not full.

All default settings have been used, but the start battery is regularly at 12.3-12.5v.

Are the default settings too aggressive, do they need to be dropped. If so any recomendations. I have done various searches and running second battery charging with Euro 6 engines seems to be a dark art with little information about what a good set of settings should be.

My instincts as opposed to science or knowledge is to:

Drop Input Voltage Lockout to be 12.1v / 12.3v. After starting the engine and idling the starter battery is regularly at 12.2v, so restarting shouldn't be an issue at 12.1v.

Setting Start Voltage to 13.2v

Setting Delayed start to 12.8v

Setting shutdown voltage to 12.7v

Any guidance, are these values too low?

Many Thanks

No more stored Ah with Lynx shunt

Hi, I changed from the bmv 712 to the Lynx Shunt. Now I have the problem, that the Lynx Shunt is not counting or showing the ah charged to the battery as the bmv and I guess the smart shunt does. It only shows the drawn ah from the battery, but not vice versa. Why is that dear Victron? Why can the shunt not show the ah charged to the battery? Is there any was to find out the charged ah to the battery? Thanks

Orion-Tr Smart DC/DC control and grounding clarification


I am building a 24V setup very similar to the victron van install (https://community.victronenergy.com/articles/15035/victron-vw-van-electrics-install-schematic-drawing.html) on a old Mercedes Benz truck (no smart alternator).

Instead of the Buck Boost, I will use the new Orion-Tr Smart 24/24-17A (400W) Isolated DC-DC charger behind a Battery Protect.

My negative bus bar and the enclosure of the MultiPlus are grounded to the chassis using 4mm2 wire.

The manual of the Orion-Tr Smart (https://www.victronenergy.com/upload/documents/Manual-Orion-Tr-Smart-Charger-Isolated-EN-NL-FR-DE-ES-SE-IT.pdf) states on page 4:

"Remote on-off
Use the remote function to enable and disable the converter remotely with the remote on/off connector or using the
VictronConnect app. Typical use cases include a user operated
hard wired switch and automatic control by for example a Battery
Management System. If the minus of the service battery is not at
the same potential as the minus of the alternator or starter battery
an isolated remote on/off cable between the BMS and the on/off
port is required, see chapter 4.4 for details.

This should not be the case in a vehicle, but the on page 10, Figure 4:


there is an isolated remote on/off cable shown.

So here are my questions:

  • Is it correct to ground the negative bus bar and the enclosure of the MultiPlus to the vehicle?
  • Is it necessary to also ground the enclosures of the MPPT, the Orion etc. in such a setup?
  • Basically, I want to use the automatic "engine running" detection mechanism of the Orion-Tr to enable it. In case the VE.Bus BMS triggers the charge disconnect, the BatteryProtect on the charge side disconnects the Orion-Tr to protect the batteries. The question now is, if I also need to deactivate the Orion-Tr to protect it from beeing damaged, like with a MPPT? How would I do this? I have a "Non inverting remote on-off cable, ASS030550200" in my hands. It does not look like the one used in the diagram, it only has three cables (red, black, yellow).

Proper way to charge 12V bank from 48V bank ?

Hi Forum. This boat has 48V battery bank with some 12V loads that draw more than 30A. I was thinking of a Victron DC-DC converter, but doesn't it make more sense to use a DC battery charger to ensure that an absorption charge happens when necessary ? I'm curious what others recommend or do in such a situation ?

Orion Tr 12/12-9 will not start charging.

Dear all.

I have just installed my Orion in my caravan. My intension was to charge the caravan battery from my car while driving.

Input comes from the car, and output is connected to the caravan battery. Remote is jumped.
The converter is set to an output of 14,4 unloaded as per the manual.

When i hook up the car the ON/OFF led is lit. No current flows to the battery.

The only way i can start the Orion is to disconnect the and reconnect the caravan battery while the car is connected..

Can someone please tell me what I'm doing wrong?

Thank's in advance.
