Victron AC Current Sensor:
The AC Current sensor is a simple external current sensor used to measure AC Current, Power (VA) and calculate the energy of a PV Inverter connected to the AC input or output of a Multi or Quattro. These values can then be displayed and sent to the VRM website by the Color Control. The two measurement wires can be connected to the AUX and/or temperature sense input of a Multi or Quattro.
