Help with installing a 600amp meter without a shunt??

Hi, hope you can help.
We have a bank of 8x150 amp 12V dc battery’s connected to an inverter. We would like to put in place an amp meter that will read up to 600amp dc battery side.
To do this, we realize a shunt would have to be fitted & an amp meter taken from this for the display.
I would prefer not to use a shunt as it’s just another joint in an area of heavy electrical loads.
I have seen that a shunt could be done away with & a coil/transformer that is like a round donought put in place of the shunt.
The problem is that they seem to take readings from (lets say) 100-600amp & not from 0-600amp. Is there a way around this to enable readings from 0-600amp using this coil type of sensor?

Many thanks.

Chris.

i am not sure, the device the the wire pass through is called hall effect current sensor
try searching google of these type of devices
good luck

The doughnut shaped coil/transformer is called a CT (current transformer).

0-600A is a big range to be covered with one sensor. You will do good to have two sensors one for the lower range say, 0 - 150A and the other for the rest of it.

Eh !!! Just a basic doubt.
Is a transformer able to measure DC currents? I don't think so.
