You can buy a terminal post (12v planet keep them) or you can simply use a stainless nut and bolt, suitably secured in place. If it suits you, you can connect all of those connections on the left battery negative to a terminal post and run a single cable from the terminal post to the busbar, if you choose to do this, i'd make the link cable from the same cable as used on the batteries. All negatives on the left hand battery must go to the busbar. Best practice would be to mount the busbar where convenient, a cable must go between the busbar and the shunt, you must connect the battery end of the shunt to the battery bank, this should be the negative on the right hand battery.The notes on your picture are correct, not that there is only a single negative busbar. The negative connection from the charger also goes to the busbar, as will any other negatives.
The engine battery and engine negatives connect to the busbar, as per my schematic in post #2. You then need to move the cable from the other negative terminal of the domestic bank to the shunt, as you have noted in the picture. In the last picture, the cable marked for investigation needs to go to the busbar, you then need a cable from the busbar to the shunt "load" terminal and another cable from the shunt "battery" terminal to the terminal of the battery, where this cable came from. Using the Sterling monitor in this way will not affect the Victron one. You could, if you wanted, leave the engine battery shunt and continue to use the Sterling monitor for the engine battery alone, it may save having to find a way to hide the hole that would be left by removing the Sterling display. The Sterling shunts are fitted to the positive circuits, so just remove them and connect all of the cables that are fitted to them directly to the batteries. Where should I put the BMV? Is it just a case of replacing the existing shunt? I have yet to trace all wires as they go into the interior of the boat - I'm planning to do this in the next few weeks. I believe these are connected to the Sterling Battery Monitor currently installed (I want to replace to the BMV to access the smart functionality like 'remaining time'). There are two separate shunts fitted to one of the Vartas batteries and one to the Numax. I have also included the connection to the start battery also (Numax 12v 70ah). The Varta house batteries are wired in parallel. Please find a summary of the current set-up and wiring diagram (work in progress) below - thank you for your help! However, I've already hit the limit of my current understanding and was hoping for advice from the forum. We're trying to start with the installation of a Victron Energy Battery Monitor (BMV-712 Smart).

We have an Ampair wind generator and 2x Varta 12v 180 Amphour house batteries currently and will be assessing their health also.

As part of this we are planning to install solar panels and an improved battery monitoring system. Having bought our boat a year or so ago, I'm now trying to get to grips with the electrics.
