BMV-712 Smart - Load Side

Hello I recently purchased the BMV-712 Smart. My setup is I have a mppt / one lithium lifepo4 / one inverter / charger. My question is what do I connect to the load side of the shunt? My apologies if this has been asked and answered. After reading some other questions and answers I'm I to connect the negative cables from the mppt / inverter / and dc panel to the LOAD side? Thank you

On the battery side is only the battery and on the other side is everything else.
(Also there should only be the shunt connected to the neg of the battery, nothing else)

Yes, that's correct.
If this installation is on a car or boat and you have a connection to the chassis, this connection also have to be on the "Load" side of the shunt.

Thank you - installation is on a van conversion - So I am to connect my ground also to the load side?

As I wrote already, to the only thing connected to minus of the battery is the shunt everything else is on the "Load" side.
