Thank you very much 
i will Check this. 
OK I was afraid of that problem. However, if I buy a new CCGX will the processor been updated to handle the new upcoming firmware updates?
The CCGX has not been updated, any unit you found for sale would be old stock or second hand. Consider a Cerbo GX or Ekrano GX. The Cerbo GX can be matched with a Touch 50 screen that has an adaptor to fit into a hole vacated by a CCGX, although the Cerbo GX design is around 5 years old now.
I updated my previous message: it’s a Cerbo GX which is loosing the connection to the BMS (#67) when updating to V3.60
@h4i5j6 you have a systems with mods. (I saw you mentioned jkbms, and maybe you have more).
From Victron side, we’re not supporting those, and also no interested in investigating for quality or bug fixing purposes. I hope you understand.
Two possibilities / recommendations:
-
disable the mods, see what happens then. Per v3.60 there is a button for that in the menu, see Settings → General → Modifications
-
check CPU usage.
Thanks, Matthijs
ps @h4i5j6 , I couldn’t help my self 
and checked if I could find your system on VRM. And wow that’s a cool one! It must be one of the largest systems in terms of number of connected devices that I’ve ever seen:
- 6 batteries
- 4 mppts
- 7 tanks
- 1 grid meter
- 11 temperature senders
- 1 alternator
- 2 individual VE.Bus systems
I’m not surprised if that Cerbo is hitting its CPU limits. And recommend to upgrade to an Ekrano GX, it will be much better suited to handle the related load.
Hope this helps,
All the best! Matthijs
…thx! Uninstalled GuiMods etc. which are not in use anymore. No more mods, but using SignalK for bringing any vessel related information incl. N2k to multiple Android tablets, 24" touchscreens, TVs.
Tomorrow two 10k/48V Quattros and another energy meter will be integrated, another Multi RS is installed but offline waiting for parallel firmware (we tested having one in inverter/charger mode and the second in charge only, a ATS is keeping A/C devided), two alternators on two Safiery ScottyAI 24/48V 3kW DC/DC converters (not visible but connected via Ve.Can) plus two 230V/18kW Onan Generators.
Ekrano: no need for displaying Victron data-only at the engine room.
So on top of all that you also have Signal-K ? Cool!
Then really I recommend to go to an Ekrano GX. Not for its display, but because it has at least twice the CPU power as the Cerbo GX has, and perhaps even more.
(Cerbo is dual core, Ekrano is quad core).
It really has much more CPU power than the Cerbo.

Now that I have reverted to version V3.55, I’m still experiencing issues. Everything functions correctly throughout the day, but as soon as the PV panels catch the first daylight, I receive messages that various BMS connections are not found. As a result, the Quattro shuts down due to a presumed low battery voltage. A minute later, the connections are restored and everything starts up again.
Unfortunately, by then my drinking water preparation system is disrupted, all my smart lighting as well, and all computers restart, etc. This is not a sustainable situation.
It seems that something from the update to version V3.60 may still be lingering somewhere, because everything was working fine before that update.
Is it possible to reset the CCGX to factory settings and then reinstall version V3.55 from that point?
I am asking these questions because there is no space for a Cerbo or Ekrano in the current layout. This means that many modifications will be necessary. This will be an expensive operation that will not provide me with any additional benefits.
Thanks in advance for any help
@BobU It is documented in the manual. https://www.victronenergy.com/upload/documents/CCGX/140558-CCGX__Venus_GX__Cerbo_GX__Cerbo-S_GX_Manual-pdf-en.pdf
I downgraded to V3.55 and the system runs into the same circle of #67 loosing BMS at least as soon as one of 4 MPPTs kicks in.
(VRM Alarmprotocoll: not more than 2 failures during nighttime, lot off starting daylight)
My conclusion is,
1.) once updating to V3.60 downgrading doesn’t set the CerboGX to its previous status. Reminder: no issues like #67 before first time updating to V3.60,
2.) MPPTs are involved
So, what to do now?
(Ekrano is not an option as there are 3 inputs for tank sensors instead of 4 at the CerboGX, no display is needed, limited space for installation)
Thank you for your suggestion. However this is the procedure that I followed already. You can go one step back in firmware version.
In Victron professional there is a change log for the firmware versions, but this only describes an update from 2018 when the step from version 1 to version 2 was made. It doesn’t contain a full history of firmware versions.
So I’m at the same sutiation as user h4i5j6
What to do now?
To be absolutely sure, did you go through the factory reset procedure in Section 17.
I have already invested a lot of time and communication in the areas of Victron together with SignalK, KIP, YachtDevices, and connection to marine installations.
A simple procedure in the sense of backup followed by a factory reset and importing the backup is not possible here. I estimate it’ll be a 3-5 day job.
I am happy to help you narrow down the bugs conc. V3.60, but please without “go back to the start and begin again.”
Hi both
@BobU : I’ve checked your system, now running v3.55, in more detail. I’ve been able to make one change, that I expect to help prevent the inverter to briefly switch off.
A few notes:
- I checked the CPU load on VRM, up to 6 months back. And it has always been on the edge, sometimes over the edge. For example on Feb. 12th this year, also Error code #67 No BMS.
- The CCGX is rebooting because its out of memory; And the same thing has been happening in the past as well. April 25th, May 6th, May 29th. and more dates.
- Here is a graph of dbus round trip time, the base level is 60 to 200ms, already high.
-
That CCGX has been at or over its limits as far as I can see in the past using VRM, and still is today while running v3.55.
-
For a 100% stable system, the recommendation remains to update that hardware. Sorry. We might find an improvement or solution in the coming weeks - but similarly also might not.
But for now, you could also wait and see a bit; we might find further improvements, like the fix that I did manually, and incorporate them into a v3.56 for example.
By the way, while looking into this I accidentally caused a reboot of your CCGX. Which by the looks of it didn’t cause the inverters to shut down. But if it did - then mijn excuses!
@h4i5j6, see mail I’ve sent.
Have a good evening.

Could building your own Cerbo using a Raspberry Pi be an option?
I could—with reluctance—see a Raspi5 exclusively for SignalK on the distant horizon, at the earliest in 2026.
However, a third-party product should never replace the original Victron products. Let everyone do what they are supposed to do, what they are good at and what is their responsibility – assuming that Victron itself manages and supports all Victron devices.
Believing that individual solutions can be better or more sophisticated may be valid in the short term, but in the long term and from a safety perspective, this seems to me to be short-sighted.
Keep in mind that we are not talking about a “residential installation”; the system is located on a transoceanic motor yacht, and Cerbo, together with SK and Yacht Devices, provides the complete instrumentation based on NMEA2000.

Thank you again…
I did overlook this chapter. Sorry for misinforming you.
At this moment I’ve disabled all the equipment that is causing the system to trip. So for the moment I’m safe..
We have guests in our holiday home at the moment so I need to postpone the exercise of going back to factory settings for a while, but will do it as soon as possible.
Fingers crossed…
Absolutely! I don’t allow auto update on any of my devices: phone, computer; tablet; any equipment.
Hi @BobU ,
I recommend to wait a bit: we might come out with some improvements that will significantly reduce the risk of the No BMS errors / inverter shutdowns on heavily loaded systems.
And in general, having seen your system in more detail: I don’t think a factory reset is going to make any difference.
Will keep you posted, Matthijs
Ps. Noted with regards to the guests. I’ll not touch the system.
