Hello,
I have started building a diy battery unit for the Growatt SPH 10000 high voltage system together with the DIY bms system from Stuart.
The controller and modules work but now I have some challenges.
These are the shunt and the canbus protocol.
Shunt:
The shunt can have a maximum of 85 volts while a high voltage system can go up to over 400 V.
At first I thought to solve this with a voltage divider but now I doubt this.
Canbus:
The canbus protocol seems to match the experimental Pylontech force protocol,
which is only sent once by the BMS?
Hopefully there are people who can give me some good hints.
B.v.d.
Leodien.
