Hi everyone ,
I would like to know why is the VE.bus SOC differ to that of system overview ? which one should I used .
asked
VE.bus SOC vs System overview SOC on VRM data report
Do you have another source of SOC information in the system?
For example a Victron BMV or an managed lithium battery with a CANbus connection?
Generally speaking, you should use the System State of Charge, as it will select the one of highest priority automatically (or be overridden via the menu setting within the GX device).
Hi Guy ,
I do not have any external sensor that gives me the SOC .All the infor i get is directly from the VRM data report. My problem is that the System overview information does not have all power flow information for DC or AC side of the inverter / charger. And, I am not sure where the sensors for monitoring are positioned.
ACTUALLY , I THOUGHT THAT THE INFORMATION REPORTED BY VRM DATA REPORT UNDER SYSTEM OVERVIEW IS JUST INFORMATION FROM THE VE.BUS THAT HAS BEEN AVERAGED OVER FOR THE PURPOSE OF REPORTING . MY LOGIC IS THAT ALL SENSOR THAT ACQUIRE INFORMATION( CURRENT AND VOLTAGE) FOR MPPT CHARGER AND MULTI ARE UNDER VE.BUS .
Below is a schematic diagram of the system with indications of where I THINK THE SENSORS ARE LOCATED TO MONITOR THE POWER FLOWS .NB: THE GRID TIE INVERTER ON THE AC SIDE OF THE MULTIPLUS IS THE SMA SUNNY BOY 4000TL
