Ok, got the RS232 working now.
I use the pin layout as described by HighTechlab.
The driver (I use win10) is the most important piece here to make it working, also make sure you have a software that will use RS232.
I use PbmsTools HS1.0.6 (but it also works with other PbmsTools versions)
I also have the communication between the inverter and battery working.
But even I have the BMS communication running, the inverter does not stop discharging the battery until the battery goes around SOC 5%.
I can see that when I change the Pack OV Alarm to e.g 52.50V, the inverter receive this information and will use 52.50V to charge the battery.
So it looks like I have to tweak these BMS parameters in the battery??
MY QUESTION is: is there an explanation of all these parameters and how the inverter react on these? (inverter like Axpert MAX II 10kw)
For example I would like to know which parameter (in the battery) I can set to stop charging at around 80% SOC. (is it Pack OV Alarm?)
Which parameters will stop the inverter discharging the battery around 20% SOC? (is it Pack UV Alarm?)
thanks in advance!
