I have a question about synchronization of the SOC:
I have recently an new CCGX and connected to the Multiplus with VE bus cable. Also a BlueSolar 150/85 is connected with CANbus cable to the CCGX.
The SOC goes every day a little bit up when the sun shines. After one week the SOC is now till 35%. While the the battery (1000Ah) is in state of absortion or flowting. Is this correct or is there a possibility to synchronize this directly?
It is possibly a seting that is not quite right for you battery type. Absorption and float is usually voltage based (your battery manufacturere will have a datasheet for that info)- Also check your battery capacity setting.
What is measuring the state of charge? The Multi on VE Bus? This can be checked under system setup and battery monitor.
Hi @Pretender
Why don't u connect the BMV600 to the CCGX and use that for SOC? it is always more accurate.
Hi Daniël,
Thanks for your advise.
That was initially the intention. Turns out the VE direct cable doesn't fit the BMV600. The BMV600 has a different connector. Connecting a different cable is unfortunately not an option because the renovation of my house has been completed. The BMV is nearby the battery and the CCGX is 10 meter away in another room. That is why I want to read the SOC through the Multiplus.
