AC Current sensor - single phase - max 40A

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 Note:
This 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.
