Hello,
I am new here. Sorry for my English, I am a french DIY.
Configuration :
.Multiplus2 24V/5000VA (ESS mode)
. Victron lead carbon batteries 24v 320Ah
. Cerbo GX
. BMV
. Battery balancer
. Victron battery fuse and breaker
I noticed when the discharge current is over 100A, the low battery led is blinking even with a 100% SOC.
I extracted the datas from VRM and do not see anything wrong. There is a slight difference of voltage between BMV and Multi and I know where it comes from (improvement ongoing with NH00 breaker)
For example, for 124A discharge peak, I have Multi at 23,48V and BMV at 23,46V. It is far from limits in Veconfigure Inverter tab DC lows 18,6/21,8/21,8
On the other hand when setting the ESS I got a pop-up with cut off limits-current : 0,005C - 24V / 0,25C - 23,3V / 0,7C - 22,8V /2C - 22,4V.
When reading the datas I got low voltage warning at 24,7V for 0,24C and 23,48V for 0,39C. Still far from cut-off limits.
In the cerbo gx, I disabled notifications for “warnings”.
I limited the inverted power to avoid possible shutdowns.
I do not understand what is going wrong.
Maybe, I am worry for nothing and I should not consider this blinking led.
Thanks in advance to anyone who can help me to sort this out.
Best Regards,
