Precision AC Current Monitoring for Victron Energy Systems
Enhance Solar Visibility with the Victron 40A Single Phase Current Sensor
The Victron 40A Single Phase AC Current Sensor provides a reliable, non-invasive method for measuring AC current in your Victron Energy installation. Designed to integrate seamlessly with compatible Multi and Quattro inverter/chargers, this sensor enables accurate monitoring of AC-coupled PV inverter output, delivering critical data on apparent power (VA) and energy production (kWh).
By connecting to the AUX or temperature sense input, the sensor eliminates the need for complex external metering hardware. It empowers system owners to visualise solar yield directly on a GX device and via the VRM Portal, ensuring complete oversight of energy flows without additional communication modules.
Engineered for Accuracy and Long-Term Reliability
At the core of the sensor is a precision toroidal current transformer, which clamps around a single AC conductor for isolated, safe measurement up to 40 A. The fully potted enclosure (IP54) protects internal electronics from moisture, dust, and vibration, making it suitable for installation in equipment rooms, marine environments, and outdoor enclosures where conditions can be demanding.
Onboard DIP switches allow straightforward configuration of the power range (1.5 kW to 7 kW at 230 V AC), matching the sensor to the expected PV inverter output. This flexibility ensures optimal resolution and accuracy across a variety of system sizes, from small residential setups to larger off-grid applications.
Key Features
- Non-invasive toroidal sensor measures up to 40 A AC without breaking the circuit
- Configurable power ranges via DIP switches for precise scaling (1.5 kW, 3 kW, 5 kW, 7 kW)
- IP54 potted enclosure resists moisture, dust, and vibration for long service life
- Simple two-wire connection to AUX or temperature input on Multi/Quattro units
- Enables solar production data on GX devices and remote monitoring through VRM
- Supports up to nine sensors in a single system for comprehensive multi-point monitoring
Seamless Integration with Victron Ecosystems
Installation is straightforward: pass one AC wire from the PV inverter through the sensor’s aperture, connect the screw terminal output to the inverter/charger, and configure the assistant in VEConfigure. The sensor draws no external power and introduces negligible burden on the measured circuit. For three-phase systems, one sensor per phase is required, and all can be aggregated in the GX device for a unified view of total solar production.
This sensor is particularly valuable in AC-coupled systems where a PV inverter feeds into the AC input or output of a Multi or Quattro. Without it, the inverter/charger cannot distinguish between grid import and local solar generation, leading to incomplete energy data. By adding the current sensor, you gain full transparency into how much energy your solar array is contributing, enabling better energy management and system optimisation.
Applications
- Monitoring AC-coupled solar production in residential and commercial Victron systems
- Retrofitting existing Multi/Quattro installations with cost-effective energy metering
- Marine and mobile setups where space and reliability are critical
- Off-grid systems requiring detailed energy accounting for battery charging and load management

WARRANTY
Victron Energy Limited Warranty Policy
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.
During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like: • Reverse of battery polarity. • Inadequate connection. • Mechanical shock or deformation. • Contact with liquid or oxidation by condensation. • Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...). • Breakage or damage due to lightning. • Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening. • For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.
