Good morning.
Has anyone managed to get the Cerbo GX MK2 to recognize a UPOWER LiFePO4 UE-48LI3750I battery system via Ve-CAN?
In principle, the batteries come with their specific connection cable for Victron.
All connected to a Victron MultiPlus II 48/3000/35-32.
Should I disable the battery monitor on the Multi or not?
Any help would be appreciated. Thank you.
Buenos días.

Todo conectado a un victron MultiPlus II 48/3000/35-32.
¿Debo desactivar el monitor de batería del multi o no?
Toda ayuda será bienvenida. Gracias
This looks like the same BMS card that Pylontech uses, so should work …
Yes the battery monitor in the multi can be disabled once coms are established. Can data rate will need to be 500kbit/s
Thanks for replying.
I’ll try it. I thought it was 250 Kbps.
It seems to have recognized the battery system for a few seconds, then appears as disconnected.
I see a Dyness battery monitor, which disconnected almost immediately.
I’ll try what you’re telling me.
Hello, good morning.
I thought that with proper communication between the battery system’s BMS, the low battery voltage alarm would be resolved. Error 276 VE.Bus System [276] Low battery: Alarm.
But the problem persists, even though the voltage values seem to be within normal limits. I’ve browsed several forum threads, and it seems like a fairly common problem, and from what I’ve read, they don’t seem to have found a solution.
Any suggestions for the problem?
On the other hand, now that the BMS battery system is recognized, I’m thinking of removing the ESS assistant from the Victron MultiPlus II. Do you think it might be a good idea?
Hola, buenos días.
Pensé que con una comunicación adecuada entre el BMS del sistema de batería, la alarma de bajo voltaje de batería se resolvería. Error 276 VE.Bus System [276] Low battery: Alarm.
Pero el problema persiste, aunque los valores de voltaje parecen estar dentro de los límites normales. He consultado varios hilos del foro y parece un problema bastante común. Por lo que he leído, no parecen haber encontrado una solución.
¿Alguna sugerencia para solucionar el problema?
Por otro lado, ahora que se reconoce al sistema de baterías por BMS, estoy pensando en eliminar el asistente ESS del victron MultiPlus II.¿Crees que podría ser buena idea?
VE-Bus system means that the alarm is being raised by the inverter(s).
Use a Mk3 and Ve configure to check that the inverter voltage settings are consistent with the battery voltages.
Greetings, MikeD.
Thanks for replying.
After checking the MK3 USB several times, as you mentioned, I decided, using Victron Config 3, to remove the ESS wizard from the Victron MultiPlus II and leave the battery BMS as an external control, and everything seems to be back to normal.
Some low battery voltage or high discharge current notifications still appear, but only when the battery is discharging. They are momentary and disappear after a few seconds.
It seems there was some conflict between the two systems.
I’ll continue monitoring the system and comment on its progress.
