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).\u003c\/p\u003e\n\u003cp\u003eBy 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.\u003c\/p\u003e\n\u003ch3\u003eEngineered for Accuracy and Long-Term Reliability\u003c\/h3\u003e\n\u003cp\u003eAt the core of the sensor is a precision \u003cstrong\u003etoroidal current transformer\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003cp\u003eOnboard 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.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNon-invasive toroidal sensor measures up to 40 A AC without breaking the circuit\u003c\/li\u003e\n\u003cli\u003eConfigurable power ranges via DIP switches for precise scaling (1.5 kW, 3 kW, 5 kW, 7 kW)\u003c\/li\u003e\n\u003cli\u003eIP54 potted enclosure resists moisture, dust, and vibration for long service life\u003c\/li\u003e\n\u003cli\u003eSimple two-wire connection to AUX or temperature input on Multi\/Quattro units\u003c\/li\u003e\n\u003cli\u003eEnables solar production data on GX devices and remote monitoring through VRM\u003c\/li\u003e\n\u003cli\u003eSupports up to nine sensors in a single system for comprehensive multi-point monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSeamless Integration with Victron Ecosystems\u003c\/h3\u003e\n\u003cp\u003eInstallation 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMonitoring AC-coupled solar production in residential and commercial Victron systems\u003c\/li\u003e\n\u003cli\u003eRetrofitting existing Multi\/Quattro installations with cost-effective energy metering\u003c\/li\u003e\n\u003cli\u003eMarine and mobile setups where space and reliability are critical\u003c\/li\u003e\n\u003cli\u003eOff-grid systems requiring detailed energy accounting for battery charging and load management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTake Control of Your Energy Data\u003c\/h3\u003e\n\u003cp\u003eEquip your Victron system with the \u003cstrong\u003e40A Single Phase AC Current Sensor\u003c\/strong\u003e and unlock the full potential of your solar investment.
