i'm owner of a MultPlus 48/1600/20 and i use it to charge my DIY LiFePo4 power-storage. now i control its function by switching it On and Off with the “remote”-contact by a RaspberryPi. The RaspberryPi read the Input and Overload of my SMA-EnergyMeter and then switch the charging on, if there is more power, than i need in my house. but i find out, that i can change the charging current with Ve-Configure(windows) while the charger is loading the batteries. so i think it may be a useful function, to change the charging current depending on the overload of the PV-Equipment. I read the Documents about the protocol to talk over the MK3-adaptor, but i can't find the solution, how to set the parameter.
All the other open-source projects are made only to read and document the use of the parts.
i need such a sequence, which code i have to transfer to the MK3(FTDI), so i can set the parameter for charging current.
my main program is running in python(3) on the RaspberryPi.
thanks for help
