{"product_id":"victron-ac-current-sensor-single-phase-max-40a","title":"Victron AC Current sensor - single phase - max 40A","description":"\u003cp\u003eThe Victron AC Current Sensor (CSE000100000) is a compact, non-invasive split-core current sensor designed to measure the AC output of a single-phase PV inverter connected to the AC input or output of a Victron Multi or Quattro inverter\/charger. By passing one AC conductor of the PV inverter through the sensor core, it measures AC current and — combined with the voltage measurement already available inside the Multi or Quattro — calculates apparent power in VA and energy production in kWh, making PV inverter yield visible on any connected Victron GX device and the VRM remote monitoring portal.\u003c\/p\u003e\n\u003cp\u003eThe sensor connects via two measurement wires to either the AUX input or the TEMP-sense input of a compatible Multi or Quattro. It is configurable for four power ranges — 1.5 kW, 3 kW, 5 kW, and 7 kW — via onboard DIP switches, with the selected range determining the maximum measurable current (up to 30.5A) and the maximum input current (up to 40A). Up to nine AC Current Sensors can be installed in a single system, enabling multi-phase and multi-inverter installations to be fully monitored from a single GX device.\u003c\/p\u003e\n\u003cp\u003eThe AC Current Sensor is one of several options for visualising PV inverter solar yield within a Victron system — alongside solutions such as direct Modbus TCP communication with supported PV inverter brands. It is an ideal choice for AC-coupled systems where the PV inverter does not support direct network communication with the Victron GX device, or where a simple, hardware-based yield measurement is preferred over a network-based integration.\u003c\/p\u003e\n\u003cp\u003eNote that this sensor (CSE000100000) is a general-purpose AC current sensor for Multi and Quattro and should not be confused with the dedicated Current Transformer 100A:50mA accessory for MultiPlus-II (part number CTR110000500), which is a separate and distinct product.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eFeature\u003c\/h5\u003e\n\u003ch4\u003eNon-Invasive Split-Core Current Measurement\u003c\/h4\u003e\n\u003cp\u003eThe split-core design allows a single AC conductor of the PV inverter to be passed through the sensor aperture without cutting or modifying the cable — enabling installation on existing wiring without interrupting the AC circuit or requiring any rewiring.\u003c\/p\u003e\n\u003ch4\u003eApparent Power (VA) and Energy (kWh) Calculation\u003c\/h4\u003e\n\u003cp\u003eBy combining the sensor's AC current measurement with the voltage measurement already available inside the connected Multi or Quattro, the system calculates apparent power in VA and cumulative energy production in kWh — providing a complete picture of PV inverter yield without additional meters or external devices.\u003c\/p\u003e\n\u003ch4\u003eVisible on GX Device and VRM Portal\u003c\/h4\u003e\n\u003cp\u003eAll measurements from the AC Current Sensor are displayed directly on any connected Victron GX device — including the Cerbo GX, Ekrano GX, and Color Control GX — and are logged and accessible remotely through the VRM portal, providing live and historical solar yield visibility from anywhere.\u003c\/p\u003e\n\u003ch4\u003eFour Configurable Power Ranges via DIP Switch\u003c\/h4\u003e\n\u003cp\u003eThe sensor is configurable for four power ranges via onboard DIP switches: 1.5 kW, 3 kW, 5 kW, and 7 kW. The selected range should be equal to or higher than the maximum expected PV inverter output power — for example, a 4 kW installation should be set to the 5 kW range. Each range determines the measurement resolution and maximum input current rating.\u003c\/p\u003e\n\u003ch4\u003eUp to Nine Sensors per System\u003c\/h4\u003e\n\u003cp\u003eA maximum of nine AC Current Sensors can be installed in a single Victron system — enabling full yield monitoring across multi-phase installations and systems with multiple PV inverters, each sensor connected to the AUX or TEMP-sense input of the Multi or Quattro on the corresponding phase.\u003c\/p\u003e\n\u003ch4\u003eConnects to AUX or TEMP-Sense Input\u003c\/h4\u003e\n\u003cp\u003eThe two measurement wires connect to either the AUX input or the TEMP-sense input of a compatible Multi or Quattro. Note that not all Multi and Quattro models support the AUX input for this sensor — the TEMP-sense input is compatible across all models. The Multi or Quattro must use a control board with a firmware version starting with 26 or 27 (not 19 or 20) for compatibility.\u003c\/p\u003e\n\u003ch4\u003eIP54 Weather Protection\u003c\/h4\u003e\n\u003cp\u003eRated IP54 for protection against dust ingress and water splashing from any direction, the AC Current Sensor is suitable for installation in electrical enclosures and compartments that may be subject to occasional moisture exposure in marine, RV, and off-grid applications.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"product-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Type\u003c\/td\u003e\n\u003ctd\u003eAC current (single phase)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Input Current\u003c\/td\u003e\n\u003ctd\u003e40A (at 7 kW range, DIP switches 1, 2, 3 ON)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Ranges (DIP switch selectable)\u003c\/td\u003e\n\u003ctd\u003e1.5 kW \/ 3 kW \/ 5 kW \/ 7 kW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Measurable Current per Range\u003c\/td\u003e\n\u003ctd\u003e8A \/ 16A \/ 25A \/ 30.5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eAUX input or TEMP-sense input of Multi \/ Quattro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Sensors per System\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Devices\u003c\/td\u003e\n\u003ctd\u003eVictron Multi, MultiPlus, Quattro (firmware 26x \/ 27x)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP54\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (h × w × d)\u003c\/td\u003e\n\u003ctd\u003e70 × 50 × 80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDatasheets and Manuals\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/live\/ac_current_sensor:start\" target=\"_blank\"\u003eProduct Documentation and Installation Guide\u003c\/a\u003e\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47125545025785,"sku":"VAS10040","price":49.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/8538\/1625\/files\/Product-VAS10040-1.webp?v=1779215006","url":"https:\/\/emarineinc.com\/products\/victron-ac-current-sensor-single-phase-max-40a","provider":"eMarine","version":"1.0","type":"link"}
