Victron AC Current Sensor - Single Phase - Max 40A
Features
Measures the AC current of a PV inverter connected to a MultiPlus or Quattro
Calculates power (VA) and energy (kWh) from the inverter/charger's voltage reading
Shows solar production on the GX device and the VRM portal
Dip-switch power range: 1.5, 3, 5 or 7 kW (max input current 40A)
Wires to the TEMP-sense (or AUX) input of a MultiPlus or Quattro
Up to 9 sensors in one system; IP54
Where to use it
Visualising the solar yield of an AC-coupled PV inverter in a Victron MultiPlus or Quattro system, without a separate energy meter.
Pass one AC wire of the PV inverter through the sensor and wire it to the TEMP-sense or AUX input of the inverter/charger on the same phase. Set the dip switches to a range at or above the PV inverter's maximum power (for a 4kW inverter, use 5kW). Three-phase systems need one sensor per phase.
The MultiPlus or Quattro needs the newer control board (firmware starting with 26 or 27). Not to be confused with the MultiPlus-II current transformer (CTR110000500).
