Victron has only 5 m original VE.Can to CAN-bus BMS type A Cable.
How to do by myself this cable ? I need 10 m.

Hello
No one can tell me what variant of the drive it sells.
It is somehow easy to find out which version VE.CAN I have after unpacking (For easy return to the seller)
Picture on drive:
BMS.CAN = only Battery
VE.CAN = full Can port
Aditional information from datasheet:

My new lynx shunt with ve.can ports is sitting a foot away from my phoenix inverters with their ve.bus ports and quite obviously they cannot communicate with each other. The inverters are connected to a CCGX panel about 50 feet away obviously via ve.bus, and the CCGX's ve.can port is connected to a N2K adatper to feed my main data backbone. I would rather not pull another 50 feet of cable through this boat to bring the shunt's ve.can port up to the CCGX. What are some viable alternatives? The goal is to see the shunt on the CCGX and for the shunt data, along with (already working) inverter data to be forwarded to the N2K bus through the adapter from ve.can
Add a Venus GX (or Cerbo GX) near the inverters and shunt and connect both ve.can and ve.bus to the Venus - will the Venus/Cerbo forward all the data between both networks so the CCGX will see it all?
Add another ve.can-N2K adapter on the shunt's ve.can port - will the CCGX see the shunt data on N2K and bring it in as ve.can?
Save up a lot of money, buy the entire Victron company outright, and put them to work making all their products network compatible without the use of a different unique adapter for every device?
Thanks

Have set up comms between US3000Cs and EasySolar II with no issues. Trying to get working on an EasySolar I, which only has a VE.can input, no BMScan. Have wired up my own Type A BMScan cable from batteries to inverter, checked and is all okay.
From what I could gather it is still possible to use the VEcan port as a BMS can, but I’m having no luck getting the batteries to show up on the CCGX device list.
Hopefully someone can shine some light on this for me.

Hello,
TLD;R - I would like for a piece of mind and health of a LiFePO batteries implement a charging strategy similar to e.g. Tesla cars: Charge only to specified SoC, let's say 80%.
My current setup includes:
among other components.
In current setup, if I understand it correctly, REC BMS is periodically sending a frames on CAN Bus
advertising current SOC (among other things), and effectively controls MPPT to slow charging
when SOC reaches 98% and stop charging when SOC is equal 100%. This is a behavior
I can observe on both Cerbo GX and VRM portal.
I would like to stop charging at 80%, both for extending battery life, and for pice of mind,
that when boat is unattended, some fluke in SOC calculation would make MPPT overcharge
batteries. Is it possible?
Thanks,

Hello everyone,
could you please tell me if the BMS-CAN connection can be used as a VE.CAN connection?
The system I have in mind has 2 MPPT VE.CAN, 1 MultiPlus and Pylontech Force L2 which needs type-A cable.
Many thanks,
Mike

Hi everybody,
I have installed a "dummy" BMS over CAN (for testing) and when I remove the device I get an error67 wich makes sense as the CAN comunication is interupted. I'm using the 2-chanel CAN hat from Waveshare.
How can I remove all the CAN devices without getting those errors?
Thanks for your support!

I have a Smart Solar 150/100-Tr VE.Can connected by VE.Can to a MG Energy Master LV (With 2 x 200Ah HE batteries) and a Color Control GX. There is also a Multiplus 24/3000/70-16 connected by VE.Bus on the same system.
I'm having an occasional 'Error 67 - BMS connection lost' from the Smart Solar but I have unfortunately been unable to pinpoint what exactly is causing the issue. It never happens when the solar is isolated but randomly when solar is generating. It does not automatically recover unless I clear the issue by isolating our solar panels and reconnecting. Is this a known issue with Smart Solar VE.Can variants? Details are below. Many thanks!

Meine Anlage besteht aktuell aus
1x EasySolar 2 mit GX
2x MultiPlus 2
je 5000/48
Als Batterie sind derzeit 4 Pylontech US3000C im Einsatz.
Nun habe ich zwei weitere MPPT 250/70 ve.Can geordert und wollte diese in Betrieb nehmen.
Leider ohne Erfolg, da ich keinen ve.Can Anschluss am EasySolar habe.
Wie kann ich trotz des EasySolars2 GX einen ve.Can bekommen?
Gibt es hier seitens Victron eine Lösung?
Durch recherchen bin auf auf "Victron VE.Bus to VE.Can interface" gestoßen.
Leider weiß ich allerdings nicht, ob das Interface funktioniert am EasySolar2 GX, oder benötige ich einen Cerbo z.B um die beiden weiteren MPPT ve.Can in Betrieb zunehmen.
Vielen Dank, für eure Hilfen

Hey Everyone, I am currently working with the lynx shunt 1000, and am trying to get the actual current. I have been referencing the can registry, but I have not been able to get a message that does not return the dreaded 8000 error code. Any suggestions?
Thanks so much!

We want to add a SmartSolar MPPT RS 450|100 to an existing very early model Inverter RS Smart Solar 48/6000 and naturally use the same VE.CAN Network. Can this be done?

Hello,
I have an Multi RS Solar and the Cerbo GX device. The manual says that I have to use an cabel from the Multi RS Solar VE.Can port to the Cerbo VE.Can port. Witch cabel typ I have to buy? I Don't mean the cabel from the Cerbo VE.Can to the BMS (I have it already)... Many thanks for your answers. Thorsten

Is there any value in a ferrite choke/sleeve on a CAN bus cable?
CAN uses a differential signal as I understand it.
So is it a good/bad/indifferent idea?
I have been having some weird BMS issues, which probably is just the BMS but I wanted to exhaust all avenues.

I'm planning on an install with the following VE.Can devcies: Cerbo GX and Lynx Smart BMS. I am also planning on installing a Fischer Panda generator, and would like to use the J1939 connection method so I can log data from the generator as well as do automatic start/stop. Last, but not least I would like to have the Victron data on the N2K network to display on the chartplotter.
What would the best way to accomplish this? Reading the VE.CAN to NMEA2000 documentation, it appears that it would be best to have a VE.CAN to N2K cable for each device, but should I do that with the generator as well?
Alternatively, maybe it would be easier to keep a separate VE.Can network with just Cerbo GX, Lynx Smart Shunt, and FP generator and then install a Raspberry Pi w/ N2K and SignalK and pull the Victron data over MQQT?

When I try to configure programmable relay assistant in Multi II to close relay, using SOC level settings, seems that assistant doesn´t use SOC coming from CerboGX using BMS-CAN.
I read post with same issue https://community.victronenergy.com/questions/65651/does-the-soc-assistant-condition-on-the-programmab.html , and tried to use same recommendation , that seemed worked in that case, so I selected "enable battery monitor", because the post says that doing so, SOC will be coming from external meter (in that case BMV) and not from internal SOC calculation, as all internal data will be replaced by the data coming from external control.
Well, I tried to replicate the solution indicated in post and it simply doesn´t work. The only difference I see is that in post SOC was coming from BMV, and inmy case SOC is coming from BMS. But cannot figure out why this could be the difference for my Assistant fails to take true SOC.
Any help to understand how to use SOC coming from BMS in a Multi II assistant ?
Note: Assistant and connections work fine and activate Relay when using other conditions. The problem is where SOC is coming from.
