Hello everyone. I have a system composed of the following elements:
1 Venus GX (Firmware 2.33)
1 Multiplus II 48/3000/35-32 (Firmware 456)
1 BMV-712 Smart (Firmware 4.03)
1 Smart Solar Charger MPPT 100/20 48V (Firmware 1.46)
4 Battery 105Ah in series, 48V
The battery is being monitored by the BMV:
Settings → System setup → Battery monitor → BMV-712.
I have two operation problems:
1) During discharge without grid (off-grid), with a C4 rate, it did not respect the configuration of the cut-off value of the state of charge that was SOC = 50% in the BMV. In repeated tests the cut-off voltage value was around 47.40V.
2) During recharge, the process does not respect the values set in the VEconfig3,
As shown in the image below:
The bulk stage was started with SOC = 95% instead of 80% and the load current was 5A instead of 10A.
In the following link: https://www.victronenergy.com/live/ccgx:start#battery_state_of_charge_soc say
“Note that the Battery Monitor setting in VEConfigure3 is irrelevant. For systems like this, changing this setting will have no effect on the charge - or any other parameters - in this type of system.”
In this case, when using the BMV, how can I configure the parameters for the loading stages?
