Where in the negative lead do I install currents shunts?
The SP PRO can allow 2 external current shunts. No current shunt is required to measure the SP PRO’s current. If a shunt is being used for a charging source eg, Solar, Wind or Hydro, the current shunt must be placed between the regulating device and the battery. If a current shunt is placed between the charge source and the regulating device, then the current reading may be incorrect.
