question

I have "BMS Controlled" switched off. If it is connected to the CCGX then it will be controlling the MPPT chargers. They will say "Networked" and "ESS".

Also the LED on the MPPT flashes briefly every few seconds to signify it is being controlled externally.

You can also see more about Error 67 here:

This seems to be an unanswered question,

I have a similar Problem, Easy Solar 5000/48 with 10 BYD BOx 10, intermittently shows error 067, , all connections as recommended checked, and the only way to resolve it has been to reboot the Color GX under Settings , General, but its annoying and repetitive, all software, etc updated and reset to Defaults and reprogrammed done also,

I am having the same issue in 2022

Any news here?

Same issue here after starting an ESS setup.

Maybe flash firmware to latest?

MP2 5000/48 is 14 months old/in use

Same problem for ages with a REC BMS and 2 x MPPTs using VE.direct via USB.

I just got the answer that my Raspi environment is not officially supported, but seems I am not the only one. Over the course of a day I am getting 5-10x Error #67, system deactivates itself and cannot recover alone. I am losing lots of electric energy due to this problem :(

All FWs are up-to-date, update to the latest did not resolve the issue.

Hi, I have same problem. After restart cerbo everithink is ok.

Similar problem with this config:
Port1, Remote Panel: BMS-V2 <=VE-Bus=> CerboGX <=VE-Direct> SmartSolar 150-35
Port2, MultiPlus: BMS-V2 <=VE-Bus=> MultiPlus 1600/24

All firmwares are up-to-date.
All cables have been controlled multiple times.

The problem is mega easy to produce :

1/ turn OFF MultiPlus

2/ As soon as the sun is present, the error #67 appears on MPPT after a few minutes

Would Victron please think of it?

It's getting boring to reset the BMS connection each time...

Additional info : each time the MultiPlus is turned OFF, the EventLog says "Change VE.Bus mode from 'On' to 'Off'"... looks like a function call is wrong ;)

This is obviously not related to a "not supported" REC-BMS like in my case nor to a Raspberry used instead of Cerbo.

If you google for Victron error #67 there are so many people reporting it, I am really wondering, why Victron is not looking into it.

It seems to be deep in the software if all possible "setups" are affected.

I am using Victron Venus / Raspberry / REC-BMS combination now 10 months, everything is on the latest FW but this error occurs every day. Really annoying!

Like said in my original post: buying a cheap USB hub and plugging both MPPTs (VE.direct -> USB) into the hub and only using one USB port from the Raspberry was my final solution to prevent error #67 in combination with a REC-BMS.

How can I eliminate this problem?
I reset the MPPT to factory settings and reconfigured it, it didn't help...
I exchanged battery modules between each other (pylontech) so the master is a different BMS, it didn't help...
I tried setting the alarm rules, it didn't help...
Why does the {multiplus} VE.BUS System [276] report that it has a low battery? Is it possible to set somewhere what should be taken as a low battery?
Paradoxically, this started happening to me when I switched from offgrid to ESS.
I've already gotten used to the ESS that I shouldn't take the information about sending energy to the grid "seriously" :P (it shows well at high power - otherwise it's just informative) :)
Why does BULK sometimes light up on MPII when the system is charged ? I don't quite understand this...
It sends alarms about every 3 hours...

What else can I do to make it stop annoying (besides going back to offgrid)

Good day, I need assistance with Error #67, My system setup is as follow; 3 x MultiPlus-II 48/8000/110-100 in 3 phase configuration Firmware 502 . 2 x SmartSolar MPPT VE.Can 250/85 rev2 Firmware V3.13, Cerbo GX Firmware V3.13. I have 6 x 5.12kWh Revov batteries connected. I have ESS installed on the system.

This system worked for about 6 to 8 months without any error of this sort. I now have this error at random times, I get Error 67, with low battery Alarm and the system sometimes also switches off. I have checked the VE.CAN and VE.BUS cables but everything seems to be in order, I have read all of the posts on this topic but I dont have a solution to this.

Hi, is there any updates on this. I see people recently are still having this error. I have a system installation system has functioned well since it was commissioned at the beginning of 2023. The Error #67 error only appeared in late 2023, again yesterday and now three times today and is shutting down the system each time.

Followed all available instructions to resolve the issue -

Updated all firmwares, factory reset cerbo, adjusted settings. Followed steps outlined by Mathias here - Does GX firmware 2.80 have a bug with respect to MPPT connection to BMS? - Victron Community (victronenergy.com)

System Equipment:

• 3 x Quattro 8kVA 3-phase – FW494
• 3 x 250/100 SmartSolar – FW v3.14
• Cerbo GX - FW 3.13
• 18 x Pylontech US2000 Batteries + Hub

Any help or suggestion ASAP would be great!

Try this as you may be getting a ground loop occurring, and thus the data uart ports are getting overloaded and shuting down.

Setup a earth bus bar. And run a earth wire to all quattros and all mppt units and any other ve direct or ve.bus or ve.can units.

Then run one wire from the earth bus bar to the negative bus bar.

Basically trying to get all components to have the same ground potential.

This is not saying it will fix it but it's worth a try

An update to the solution we found to our version of this error. We found the Victron community thread that is in German, explaining that replacing the cerbo solved the issue. One week after replacing the cerbo, the issue has not been present and system has been stable.

We suspect there are Cerbos with some kind of error than can't be fixed with firmware updates or any of the solutions discussed above. I hope this helps others that find themselves in this situation.

Bitte um Hilfe, Error Code #67 & Low Battery Alarm / trotz geladener Batterie - Victron Community (victronenergy.com)

Hi , strangely after running without any problem for 2 years, I started having this problem of Error Code 67, Although the cerbo clearly sees the batteries and the multiplus are running fine , both MPPT chargers which are on the can-bus are giving this error. I wonder if this is related to the latest firmware update of Cerbo , 3.22 which was on the 27th February ...

My grounding system is fine, all devices are grounded to the same bus and also the negative of the battery.

Looking for solution and help urgently

Best Regards

I solved this issue last month.

To simulate the problem:

Disconnect all mppt´s and repower CERBO.

When connecting a mppt, the cerbo immediately goes into error 67 (BMS connection lost)

Solucion: Replace CERBO
