Hello,
i have an issue with my Victron Setup (Smart Lithium Battery, VE.Bus BMS,Multicontrol, Multiplus 800/35, Smartprotect, Smartshunt, Mppt, Orion 12/12).
The BMS doesn't disconnect loads when the Battery is empty (under 2.8 volt). And the multiplus doesn't charge when pre-alarm is enable, but will charge when battery is under 2.8 volt.
Multiplus is running BMS assistant.
Here are all things that are happening:
3.1 Volts:
- Smart Lithium Battery (in App): pre-alarm undervoltage
- VE.Bus BMS: red LED und blue LED are on. "Multiplus enable" led is on.
- Smartprotect Charge is deactivated
-Multiplus Inverter is activated, Multiplus doesn't charge (you hear the clicking sound, Multicontrol shows "bulk charging" but no current is flowing)
- Smartprotect Loads are activated
2.8 Volts:
- Smart Lithium Battery (in App): discharged deactivated
- VE.Bus BMS: blue LED is on. "Multiplus enable" led is on.
- Smartprotect Charge is activated
-Multiplus Inverter is activated, Multiplus is charging
- Smartprotect Loads are activated
Can anybody tell me what is wrong?
Best Regards
