CCGX crash and alternating device IDs

I have a rather complicated set-up(*).


Today my CCGX went through periods of rebooting continually. There is a single BMV connected to the CCGX. During the crashes, it seemed that the CCGX was assigning the BMV two different IDs (289 to start, and 288 to end). What would cause this?

(*) I have a 48V and a 24V system. They are connected by an MPPT (not connected to the CCGX).

There is a single CCGX

The 48V and 24V each have a MPPT connected to solar panels (each connected to the CCGX).

The 48V has a third-party BMS connected via CAN to the CCGX.

The 24V has a Victron BMV connected to the CCGX.

There is a Quattro connected to the CCGX.

There are two Oceanvolt motors connected via CAN to the CCGX.

Hi tylera,

if you update to v2.65 or later, that VRM instance number will not change again.

Possibles causes for the reboot could be CPU overload or memory exhausted. That would be visible on the diagnostics page on VRM, as the last boot reason.

Also, there is a Dbus roundtrip time number on that same page. Should be below approx 200ms. Lower even. If above, systems is (too) busy, and might eventually rebooted.

The only other reason for reboots that I can think of is loose wire or too low voltage in the power supply.

Btw are you sure the CCGX rebooted? One other option is that just that usb port enabled/disabled itself due to EMI issues. See manual and beads recommended, in that case.

If thats it, our repairs department could ship you a bag if needed.

Thanks for the response.


I repeatedly saw the blue start-up screen and took that as an indication of a reboot (followed by not having any data, followed by data collection and normal operation). I'm running v2.6, I'll talk to Oceanvolt as they are pesky about updates for some reason (I haven't learned yet).


Where is the diagnostics page on VRM? I don't see that.

@mvader (Victron Energy) can you help me with where to find the "diagnostics page on VRM"?

Thanks @Seb71, I hadn't seen that page before!
