Product Details
The Victron AC Current Sensor (SKU CSE000100000) is a precision external sensor designed to measure single-phase AC current, apparent power (VA), and energy in PV or hybrid systems. It is ideal for use with Victron Multi and Quattro inverter/chargers, allowing you to monitor the AC input or output reliably.
This sensor connects via two measurement wires that can be attached to either the AUX input or the temperature-sense input of the Multi or Quattro unit, making installation straightforward. Once in place, it calculates real-time energy data and transmits this to a GX control device, enabling remote monitoring via the VRM Portal.
A handy DIP-switch lets you select one of four power ranges (1.5 kW, 3 kW, 5 kW, or 7 kW), so you can match the sensor’s scale to your system’s size. The maximum current rating is 40 A, giving it enough headroom for many domestic and commercial inverters.
Built for real-world installations, the sensor has an IP54 protection rating, making it reasonably resistant to dust and moisture in semi-protected environments. Its operating power range makes it suitable for both small off-grid systems and larger grid-tied solar installations.
Victron backs this sensor with a five-year warranty, reassuring trade customers that their investment is protected. With this sensor, you gain precise insight into your system’s AC performance, improve energy management, and enable data-driven control through the GX interface and VRM.

Performance Specifications
- Maximum Input Current: 40 A
- Configurable Power Ranges: 1.5 kW, 3 kW, 5 kW, 7 kW (Selectable via onboard dipswitches)
- Max Measured Current:1.5 kW range: 8 A3 kW range: 16 A5 kW range: 25 A7 kW range: 30.5 A
- Power Step Size (230V AC): Approx. 9W to 35W (Depending on range)
- Power Step Size (120V AC): Approx. 4.5W to 17.5W (Depending on range)
- Maximum Number of Sensors: Up to 9 sensors in one system
- Protection Category: IP54
Hardware Requirements
- Microprocessor Compatibility: The Multi or Quattro inverter/charger must have a new microprocessor (firmware version starting with 26 or 27). Control boards with firmware starting with 19 or 20 are incompatible.
- Input Connection: Connects to either the TEMP-sense input or the AUX-input of a Multi or Quattro. (Note: All TEMP-sense inputs are suitable, but only specific AUX-inputs are compatible based on hardware revision).
- Communication: The Multi or Quattro must be connected to the VE.Bus port of a GX device (readout will not work via VE.Can interface).
Installation & Configuration
- Setup: Pull one of the AC wires of the PV inverter through the sensor.
- Dipswitch Configuration: Set the power range equal to or higher than the maximum expected PV power (e.g., use the 5kW setting for a 4kW installation).
- Software Requirement: Requires the "AC Current sensor" assistant to be configured via VEConfigure3.
- Multi-Phase Systems: For multi-phase installations, one sensor is required for each phase of the PV inverter and must be wired to the corresponding phase of the Multi or Quattro.
Compatibility NoteThis AC Current sensor (CSE000100000) is a specific accessory for PV yield visualization and should not be confused with the 100A:50mA Current Transformer (part number CTR110000500) used for other MultiPlus-II functions.
