My application is a boat - I would like to have the Orion XS use power from the running alternator to charge the lithium battery bank. I’m using the multiplus and it’s works fine. I’ve been turning the charging on and off with the app (until I’m confident the charging is working ) - then I’ll expe…

Can you show us your battery settings? And are you saying the Engine shutdown detection is switched off? 16v seems high and in your photo it’s showing 11.9v from your alternator.

That’s what baffles me - why the Orion is putting out 16v. Here are the Orion settings Also yesterday while underway for 7 hours engines and alternator running) the lithium bank went for 48% to 18%. I was hoping the Orion would keep the lithium charged while we are running. [Image.png]

Hi @Tjcruiser You have enabled VE.Smart networking on the OrionXS. What are the other devices on the VE.Smart network? And are they connected to the battery to which the output of the Orion XS is connected? Kind regards, Thiemo van Engelen

The only other smart networking device is the victron smart shunt.

Thank you Luda. I did indeed have the ground from the multiplus and the Orion XS disconnected - I was troubleshooting an ac gfci issue and forgot to reconnect the grounds. They are connected now

Thank you Ludo Looks like you are right, I did not have the ground connected to the lithium batteries (receiving the alternator charge). Can you tell me if I need the shunt between the two batteries ? As shown in one of the pictures ? Thanks, Tom ▶ (attachments)
