negative from solar and wind in relation to Bmv 702 battery monitor

Hi

I have purchased a BMV702 battery monitor and two mppt100/30solar controllers. My question is should the negative wires from the solar controllers and wind controller go to the BMV shunt or directly to the battery negative.

The negative wires from all charge sources and loads go to the shunt terminal labelled "Load and Charger"

The one and only cable the should connect to the negative battery terminal is the one that goes to the shunt terminal labelled "Battery Only"

The BMV will be unable to sense the current of anything connected directly to the battery negative terminal.
