Question on installing Victron smart shunt + inverter etc

I am buying a new travel trailer that comes with a 200W solar panel and MPPT charge controller (along with the 30A 120v system and 12v system). In addition, I am planning to add a whole trailer 3000w inverter (with auto transfer switch). I don't exactly know how everything is wired in the trailer. I understand that to install the shunt the battery negative is on one side and the load negative is on the other side. The load side would include the negative to the inverter and the negative to the house converter and solar charge controller. Can I wire every negative lead directly to the shunt, or should I use a bus bar?

Yes you can, but if you have to stack more than a few lugs on the system side of the shunt, a bus bar may be more practical.

Thanks. I think it will be three at most, and maybe two. And actually there might already be a bus bar in the trailer. I'll have to wait and see when I get it, but I'm trying to get parts ahead of delivery in May.

You may find stacking lugs on the shunt hard.

I found dealing with thick wires with strong batteries much harder to manipulate than the smaller 10 AWG wires.

I ended up using two 8 stud busbars on my power distribution. I wish I had one more
