I have a multiplus 2 GX and want to make a regulation in my home control system in Ess mode 3 via modbus tcp.
There is a connection and I can read all parameters on mb228.
According to the address list I can determine at address 37 whether my
battery charges from the grid or discharges to the grid.
Now it turns out that whatever I send to it (positive, negative or null), my battery is charged every time.
I have already found various things on the forum but I can’t figure out what is going wrong.
