Hello,
I urgently need help as my MPPT is going to blow my Batteries.
My MPPT is set to BMS controlled = NO.
How can this be changed? I've asked the shop I've bought it and they checked internally with some Victron colleagues and all refer me to this forum
Is there a way, even it means to send the MPPT to Victron.
But actually I hope that a setting in a commen menu (Cerbo GX) can be set back back.
Many thanks in advance.
This may not be a satisfactory answer, but here is how I solve the problem: Restarting the GX device usually causes the MPPT to return to be BMS controlled.
FWIW: If your system is set up correctly (i.e. the correct voltage limits for absorption and float are also set in the MPPT), error #67 cannot "blow" your batteries.
Hi Stefanie,
I really hope that it is that easy. I am going to restart (reboot, power off?) the GX device this evening.
I've already tried to remove/delete the MPPT from GX device but this did not help.
Settings of Absorption&Float were setup according to Batrium manual.
Once my battery reaches full state, they are currently drifting away. The BMS tells then to stop charging or get in reduced charging (1A). Both values are currently not passed to the MPPT and therfore it is charging on full power which my BMS can not handle in time and there shuts down the connection to the batteries (as it should do). But I'd like to prevent to force the BMS disconnecting instead limit charging power.
Keeping you updated if it worked.
Many thanks and regards
Joerg
Hi Joerg,
Batrium BMS is not supported by Victron. And when I google for DVCC along with Batrium and GX devices, there are many reports that this does not work as it should.
So maybe it would be a good idea if you direct your question to Batrium, since they are responsible for making their BMS compatible with the GX firmware?
I am using ESS and as I do not feed in to grid yet, I need to control the maximum output of the MPPT. Later on I hope the Multiplus 2 will use the excess power of the MPPT to feed in to grid (but this needs a lot of paper in Germany).

Yesterday I turned off and on the GX device and MPPT is now back on BMS controlled! AWESOME. So easy but so undocumented and in so many other threads not explained. Anyways this is now working, I am way more relaxed now.
On the other hand I did not enable DVCC as I understood that ESS is doing this instead. After some searching I found that ESS and DVCC can work in parallel so I've activated it. Once the sun is back so that I have enough power to recharge my batteries to full, I'll investigate how the system performs now.
