Midnite Solar MNSHUNT, a brass 50mVDC/500A current shunt with an insulated base
MidNite Solar MNSHUNT
A shunt is necessary in order to measure Amps and Amp-hours with a battery monitor. A shunt is an accurate, very low resistance resistor which is placed “in line” with the wire carrying the current to be measured. It is usually placed in the negative wire from the battery bank, such that all the current going into the battery (charging) or out (discharging) must pass through it.
It reads 0.1 mV per Amp and is constructed out of brass with insulated base. The 50mV / 500A shunt includes taptite mounting screws and has two 8-32 tapped holes on one end to attach a bus bar. This is the industry standard shunt, calibrated with an accuracy of +/- 0.25%.
