Correct Shunts for FN-DC

Postby svsimple on Tue Mar 05, 2019 4:30 pm

It is my understanding the FN-DC does NOT ship with any shunts, is this correct?

The data sheet says to use 500A/50mV shunts. Would something like this be correct?

It says it is for digital meters... not sure if this matters or not.

I saw Outback has some shunts as well, with an included bus bar. Where I'm going to mount these I cannot have the bus bar protruding out. Does anyone know if these are removable?

Thanks!

The Blue Sea shunt should work fine.

svsimple, the picture that you posted should work. As long as it has that 1mV to 10 amp ratio. Even the smaller shunt 100A/10mv should work. This one is usually for the FM60/80 charge controllers.

The bus bar is attached via two screws so it is easy to remove or flip around etc. If you have a single FX type inverter the shunt can mount directly on the chassis with the FW-SHUNT250 product. The shunt screws in place of the ground lug and then there is a flat bus bar with a slight step that goes from the right side shunt terminal to the FX negative terminal.
