Where is the full resolution version of this diagram? It shows Arco Zeus integration.

Can someone please provide a pointer to the location on Victron's site of the full resolution version of this diagram (attached)? I've hunted by various means and can't find it. It shows an Arco Zeus alternator regulator integrated into a Victron battery storage system.

I will ask a separate question about how the battery voltage sensing wires from the Arco Zeus need to be connected to the Victron system. I'm hearing that holes should be drilled into the Smart Shunt?? No thanks!

Hi John. Yep, the link is the same. :-)

So now to figure out how the Zeus' battery voltage sense wires need to be connected. My system has a Smart Shunt, a Smart BMS CL 12-100 and a Cerbo. I'm thinking that connecting the battery voltage sense wires to the positive and negative bus bars should work, but Andre Cormier (who worked on the design of the Zeus?) prefers to drill holes in the Smart Shunt! Yikes! I won't be doing that. This is where he offers this advice. Look at 12:25 in the video. It should start there.

@Valden

'Busbars' might be a bit far away. You could try with tabs on the Smartshunt terminals..

Yes, in some installations the bus bars could be some distance away, but in mine they're right next to the Smart Shunt. Cable distances are short too.

I notice in the diagram that the battery sense cables are connected to the 'bus bars', which in this setup are the Lynx Distributors. My system has simple bus bars and a Smart BMS CL 12-100. As for the Allowed To Charge (ATC) cable, I'm looking to see how it can be connected to the BMS.

@Valden in the pdf the shunt shown is bare, not a SmartShunt. Looks to be used by the zeus to monitor/control alternator current. The Victron side of the system uses the Lynx Smart BMS to monitor current.


Plenty of bare 500A-50mV shunts on ebay.

Yes, the shunt drawn next to the 24V alternator is an 'alternator shunt', not a Smart Shunt. This diagram doesn't have a Smart Shunt. As you say, it's using the Lynx Smart BMS to monitor current.

I'm presently reading the manual for the Lynx Smart BMS to find clues on how either the Cerbo or Smart BMS CL 12-100 in my existing system could be used to provide an Allowed To Charge signal to the Arco Zeus. A relay control from the Cerbo could be the solution ... . I don't have a Lynx Smart BMS.

I'll also be looking at the Arco Zeus to see what it needs for a valid Allowed To Charge voltage and whether it's adjustable/programmable.
