I always had inaccuracy in my systems between the current the REC-BMS shunt shows and the Multiplus2 DC current, although inbetween there are no loads or other systems. So i bought i victron smart shunt to check it in more detail. Now the shunt shows that the battery delivers 47Amps, but the Multiplus means, that 48,4A arrives. If you switch on in VRM the DC Loads, than it shows the missing 1,4Amps coming/going from/to anywhere which does not exist. So what is here wrong??
The battery delivers 47A, a not existing DC generator delivers 1,8A and the DC current sense of the Multi measures the 48,8A althoug only 47A exist.
I always see those differences between BMS current and MP current and it looks like it could be a source of relevant inaccuracies?
Can someone explain this? This is just a test system without grid meter installed. Values from "grid" are the AC-Out measurement from the MP2.
