I am just a bit confused. I am in the process of installing the 712 and I have factory solar. Do I need to be concerned about the factory solar or do I simply connect the shunt to the negative coming in from the battery and then from the other end of the shunt to the bus bar?

Will the accurately measure the net charging?

I believe factory solar connects to buss bar not battery, yes? To get correct measurements all neg connections must be on load side of shunt so that means on buss bar. One neg to shunt from battery and one connection to buss bar from load side of shunt

I am installing roof solar and Victron MPPT controller will connect to buss bar so 712 will measure all

The discussion we were having was about the RJ12 wire to connect the Victron shunt to the victron monitor. The Airstream pre-wire and connectors for that is 8-strand/8-pin RJ45. The Victron uses 6-strand/6-pin RJ12 (which is the cable they provide). To use the Airstream prewire, you need to change the RJ45 connector to an RJ12 Connector on both ends, at the shunt, and at the monitor. Using adapters, like Garfield is going too try (if they work), or doing what I described to use the connectors on the cable that Victron provided.

As for your shunt and factory solar, the solar should not impact your shunt installation. The negative solar controller wire can stay on the negative bus (likely that's where it is) and the shunt just needs to interrupt your negative battery cable as you described. If you have factory inverter, that one of course needs to be interupted by the shunt as well.

@pcskier

to clarify the solar +ve and -ve leads both go into a solar controller.
The output of the solar contractile has the -ve going to ground.
it is NOT connected to the solar panel -ve

if the solar controler -ve lead goes to the shunt side with all the other loads, then the shunt can include/see solar power.

if it goes to the battery -ve then the shunt will not see any solar power

Correct. The neg output from the controller needs to be on the load side of the shunt...so it can go their directly, or it can go to the neg bus if it's already there, since there is then a jumper from the neg bus to the load side of the shunt. I'm presuming that factory solar puts the neg controller wire on the bus. That might not be correct though.
