smartBMV showing wrong current

I have a smartbmv monitoring my house batteries. To charge them I have a smartsolar mppt 100/30. When the smartsolar is charging the batteries at 4.7a 13v, the smartbmv is showing 8.2a at 12.95v? I have no other chargers in the system. What could be wrong?

Could you have the wrong type of shunt selected?

Page 30 of the manual, 65. shunt current/ 66. shunt voltage.

Can you post a picture of the shunt + wiring?

The most common reason for displaying too much current is when people connect wires to the small screws on the Shunt, these screws are for connecting the circuit board, and nothing else may be connected there.

That's the reason for asking for pictures :)
