It measures import and export energy across all three phases, giving installers and system operators accurate, real-time visibility of grid consumption and feed-in. Suitable for residential, commercial and off-grid hybrid installations where precise energy accounting is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-phase energy metering with individual phase measurement for accurate grid monitoring.\u003c\/li\u003e\n  \u003cli\u003eIncludes 75A current transformers (CTs) for non-invasive current measurement without breaking the circuit.\u003c\/li\u003e\n  \u003cli\u003eIntegrates directly with Victron GX devices (Cerbo GX, Venus GX, CCGX) via RS485 connection.\u003c\/li\u003e\n  \u003cli\u003eMeasures both import and export energy, making it suitable for solar feed-in monitoring and grid interaction tracking.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.25 kg, suitable for installation inside a consumer unit or distribution board enclosure.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VRM portal for remote monitoring and historical energy data logging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe VM-3P75CT connects to a Victron GX device over RS485 and reports real-time power, voltage, current and energy totals for each phase. This data feeds directly into the GX device's energy management logic, allowing the system to make informed decisions about battery charging, grid feed-in and load management. For installers commissioning three-phase hybrid or grid-tied systems, having accurate per-phase data is essential for correct system behaviour and regulatory compliance.\u003c\/p\u003e\n\n\u003cp\u003eThe included 75A split-core current transformers clip around existing conductors without requiring the circuit to be de-energised during installation of the CTs themselves. This simplifies retrofitting into existing switchgear. The meter communicates over a standard RS485 bus, and multiple meters can be used within a single GX system where the installation requires monitoring at more than one point, such as separately metering a generator input or a sub-distribution board.\u003c\/p\u003e\n\n\u003cp\u003eData from the VM-3P75CT is visible locally on any connected GX display and remotely through the Victron VRM portal. This makes it straightforward to track consumption patterns, verify solar yield against grid import, and produce energy reports for commercial or billing purposes.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eREL200300100\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003ePhases\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e3-phase\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCurrent Transformer Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e75A (split-core CTs included)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCommunication Interface\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eRS485\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCompatible GX Devices\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCerbo GX, Venus GX, CCGX and other Victron GX products\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e0.25 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076059462\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGrid import and export monitoring in three-phase residential or commercial solar installations.\u003c\/li\u003e\n  \u003cli\u003eFeed-in metering for systems with battery storage and grid interaction, including ESS (Energy Storage System) configurations.\u003c\/li\u003e\n  \u003cli\u003eMonitoring generator input or sub-distribution boards as a secondary meter within a GX system.\u003c\/li\u003e\n  \u003cli\u003eRetrofit energy monitoring in existing three-phase switchgear without circuit interruption.\u003c\/li\u003e\n  \u003cli\u003eCommercial sites requiring per-phase energy data for billing, reporting or load balancing purposes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Energy Meter VM-3P75CT (REL200300100)\u003c\/li\u003e\n  \u003cli\u003e3x 75A split-core current transformers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe VM-3P75CT must be installed by a qualified electrician. Work inside a live distribution board or consumer unit carries significant risk and must comply with BS 7671 (IET Wiring Regulations). The meter connects to a Victron GX device via RS485; ensure the correct RS485 to USB interface cable is available if your GX device does not have a dedicated RS485 port. For grid-connected systems operating under G98 or G99 conditions, confirm that the energy meter placement and system configuration meet DNO requirements. Do not exceed the 75A CT rating on any phase.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47701549318478,"sku":"REL200300100","price":140.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-energy-meter-vm-3p75ct-rel200300100-242203.jpg?v=1747944269","url":"https:\/\/voltaconsolar.com\/products\/victron-energy-meter-vm-3p75ct","provider":"VoltaconSolar","version":"1.0","type":"link"}
