Hi,
I bought a boot and found only one charger that is conneted to batterie 2 (consumer). The batterie 1 (starter) is connected to the engine. The cetrix is managing them.
That is fine and the engine is charging both.
I added two shunts to improve the monitoing of the batteries.
I am also thinking adding a 2nd chager, as the batteries are of different typs (agm and lead acid) and have different capacites.
First question:
Does ist make sence or will the cetrix interfear with the chargers and the shunts?
If it makes sense, AI suggests the following wiring:
For a Victron system with two batteries (agm, ead acid), two Smart IP chargers, two shunts, and a Cyrix coupler, correct wiring is crucial for accurate data.
Basic principle of the wiring diagram
Battery connection (negative side):
Each battery gets its own SmartShunt.
Connect the negative terminal of Battery 1 exclusively to the “Battery” side of Shunt 1.
Connect the negative terminal of Battery 2 exclusively to the “Battery” side of Shunt 2.
All loads and chargers (negative) are connected to the “Load” side of their respective shunts.
Connect the “Load” sides of both shunts via a common negative busbar to create a common reference potential.
Charging systems:
Connect charger 1 to battery 1 and charger 2 to battery 2 (positive to battery positive, negative to the “Load” side of the corresponding shunt).
The Cyrix-ct is connected between the positive terminals of both batteries. It automatically connects the banks in parallel as soon as a charging voltage is present on one side, and disconnects them during discharge to protect the starter battery.
Any comments on this?
Thanks
