I have an MPPT 150/70 to charge a 220 Ah 48V battery bank and also a Quattro 48/5000 inverter with a temperature sensor. This sensor is actually wired on negative battery terminal.
Now I'm adding a BMV712 500A 50mV shunt on the negative battery terminal.
Question: where temperature sensor should be wired now ?
- always on the negative battery terminal ?
- or on the "Load and Charger" shunt terminal ?
If the sensor is "electrically isolated" it can be wired on the battery terminal, if it is not, it must be wired on the "load and chanrger shunt terminal to get the same potential than before (without the shunt.)
