Victron Shunt Description: A shunt is added to a system to measure current flow. This is needed for system monitoring or to calculate the battery state of charge. A shunt is a resistive element. When current passes through it a small voltage drop will occur over the shunt. If the current is small the voltage will be low, and if the current is large the voltage will be higher. If the current flow reverses, the voltage drop will change polarity. The voltage of the shunt is an indication of the amount of current and the direction of the current. This information can be used to find out how much current runs into a system or for battery state of charger calculation. A shunt has a current and a voltage rating, for example, 500 A, 50 mV. This means that if 500 A current passes through the shunt, there will be a 50 mV (= 0.05 V) voltage drop over the shunt. The shunt needs to be rated to the maximum DC current that will flow into the combined consumers in the system
