Hello!
Is this the best way to connect smartshunt to my boat?
I dont know if I can run bowthruster and anchorwinch trough the shunt?
I think it will be too much? Bowthruster is like 250a fuse, and anchorwinch 125a.
The engine has two positive outputs thats why there are two lines, it will feed the start battery to its full then feed the consumer bank.
You seem worried that a 500A SmartShunt is too small? You can buy the shunt in bigger sizes, but cost more. But bear in mind that 500A @ 12V nominal is 6000W, and you'd need a lot of battery to do that for long. And monstrous wires.
If you bypass the shunt with anything, then it can't monitor the battery and becomes just an ammeter for the circuit it's on.
That diagram 3.4.1 would technically be ok as the positives aren't connected anywhere, and the negatives just a common ground link. In theory no current would flow, but I wouldn't do it that way.
Hi John!
Yes, I thought the 1000a haden't come out yet, but i can see now that i have.
I am a little worried because the bowthruster is fused at 300a and anchorwinch at 150a, so i will go for the bigger shunt and i don't need to care and worry anymore. =)
Thanks för you time!
Not good. Check Victron site, they have many diagrams with examples.
I have looked a lot.. =)
Maybe this is better?
They have one pic with - to startbattery before shunt, and one after.. confusing!
In most cases the bow thruster and anchor winch will be supplied from the engine cranking bank due to the high current draw. The cranking batteries will have a higher CCA rating and are therefore better suited to this application. These two items are also generally only used when the engines are in operation.
The shunt would most likely be installed on your auxiliary bank and therefor not required to measure the current flow of these two devices.
Hope that helps.
