Help with install of Victron Energy Battery Monitor BMV-712 Smart

Thanks Paul. Does below look OK to you?:

Yes there is both a bow thruster and windlass

It's a split charge diode, the input is connected to the input terminal of the Argo. it's possibly there to charge a battery at the bow for the windlass or bow thruster ?

If it is and i was the OP, i'd replace it, and the Argo, with a 3 output Argofet, neater, tidier and less voltage drop.

Yes, all correct.

Not wanting to cause any confusion, but if you are making some new cables up, you could turn the right hand battery the other way around and short the cables that link + to + and - to -. It's only a cosmetic thing, though, so don't worry if it's too much hassle.

Thanks Paul, really appreciate it.
Is there any particular kind of busbar you'd recommend?

If the windlass and thruster have a battery at the bow, you'll most likely find that the cable from the diode (the black, finned box, beneath the Argo) goes to it, to charge it. As a future project i'd look to replace the diode and the Argo with a 3 way Victron Argofet. It will be tidier and the Argofet has much less voltage drop than the older style diode splitters. It's a very simple job, remove both devices and the short cable that connects the input of the Argo to the input of the diode. Fit the Argofet, connect the cable that was connected to the Argo input to the Argofet input (this is the cable from the alternator. The remaining three cables go to the three outputs of the Argofet.

You have a few heavy cables there, so i'd use something like this: Busbar, Black Power Distribution Point, 210 Amp, 1 Post

Brilliant, thank you. Going to measure up tomorrow and then order wiring and busbar etc. Once I have the BMV installed next up is 2x170 watt semi flexible solar panels and a Victron MPP!
