Hi all,
I,m trying to figure out how to use 2 bmv,s on my boat system.
I have 2 seperate circuits, one for start battery and one for accesoires.
I would like to know both soc,s so i have 2 bmv,s . The start battery gets default charged by the alternator, the accesoire battery gets loaded by the default solar panel. (default because in between is a cyrix.
Placing the shunts is troubling me, how do I place the shunt. The starter circuit has some devices which are grouded by the metallic shell of the boat, like starter engine, and dynamo, but of course also uses a negative cable. . The accesoire circuit does nog have this and therefore a minus cable is used only to power electronics inverters etc. However i,m confused If I connect both shunts of both bmv,s together to the metallic frame that the readings won`t be correct.
I,ve created a scheme, maybe that can clarify the situation.
