A shunt is simply a very low and very precise resistor placed in series between the source and the load. Usually looks like a thick wire. When current flows through it, a small voltage drop is generated, which can be measured with a simple voltmeter. The trouble is selecting the right size shunt value so that you can get a good reading, yet small enough not to suck up too much of your voltage. And then there is the power dissipation factor. I wouldn't want to drop more than 0.1v at 200A. Even at 0.1v and 200A, the shunt would have to be rated for at least 20w.
BTW: Eagletree does make an add-on sensor that measures up to 300A, but isn't explicitly said to be compatible with the micro e-logger. IIRC, it is for the other recorder unit.

Brian,
It is BNB Products, I typed BNP. Here is the link:

I have to admit, I was a little scared trying my Schulze 18.97KWF. Good thing it only thermaled. I reset it and it is working fine.
