I am looking for advice on wiring up a victron smart shunt to victron inverter as I am not getting + Current when the bus is started and batteries should be getting charged via the alternator (shows over 28v but the current shows as a minus for the draw from the inverter).
I think i may have wired something incorrect (possibly the bus starter batteries to the leisure batteries)
Attached is an image of how I have wired this up
Hi @raymonddaf,
wiring diagram looks ok to me, provided that it's exactly wired like in the diagram and the shunt battery side is on the battery negative.
I'm not sure about your question regarding the minus current. That's what I would expect to see when the inverter is switched on (regardless of the alternator current because that current is not measured through the shunt).
And I think you can't charge both battery banks at the same time with your alternator. You would at least need a charging diode, Cyrix -ct or a DC-DC charger in between.
Your mistake is the negative wire between starter batteries to the leisure batteries.
This wire must be connected to the "load/charger" side of the shunt.
Or remove this wire and connect the "load/charger" side of the shunt to the chassis.
Hi Matthias,
Cheers for the reply.
So just so im correct all i need to do is:
1. Remove the wire indicated (from neg starter to neg leisure batteries)
2. Ground the circled wire.
So this will still keep my leisure batteries as 24v (2 x 12v)?
