It measures AC energy flow at the grid connection point or on AC loads, giving a GX-connected system accurate, real-time visibility of import, export and consumption. It is suited to professional solar, off-grid and grid-tied installations where three-phase monitoring is required.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-phase AC energy measurement using 5 A current transformer inputs, compatible with external CTs for non-intrusive installation.\u003c\/li\u003e\n  \u003cli\u003eIntegrates directly with Victron GX devices (Cerbo GX, Venus GX, Color Control GX) via RS-485 Modbus communication.\u003c\/li\u003e\n  \u003cli\u003eMeasures both import and export, making it suitable for grid-tied systems with feed-in monitoring requirements.\u003c\/li\u003e\n  \u003cli\u003eCan be configured as a grid meter, generator meter or AC load meter within the GX device interface.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.3 kg, designed for DIN rail mounting inside a distribution board or enclosure.\u003c\/li\u003e\n  \u003cli\u003eSKU: REL200320100 | GTIN: 8719076072539\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe VM-3P5A connects to a Victron GX device over RS-485 and reports real-time power, voltage, current and energy totals for each of the three phases. This data feeds directly into the VRM portal and the local GX display, giving installers and system owners a complete picture of energy flow without relying on estimates or inverter-side approximations.\u003c\/p\u003e\n\n\u003cp\u003eThe 5 A CT input design means the meter itself carries no mains current. External current transformers clamp around the live conductors, which simplifies installation and avoids the need to break the main supply cables. The meter supports multiple roles within a single system: one unit can monitor the grid connection point while a second monitors a generator or a sub-load. The GX device handles the role assignment through its settings menu.\u003c\/p\u003e\n\n\u003cp\u003eFor installers working on three-phase ESS (Energy Storage System) configurations or three-phase grid-tied systems with Victron Multi or Quattro inverter-chargers, accurate grid metering is a functional requirement, not an optional extra. The VM-3P5A provides that metering in a form that integrates natively with the Victron ecosystem.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: REL200320100\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076072539\u003c\/li\u003e\n  \u003cli\u003ePhases: 3\u003c\/li\u003e\n  \u003cli\u003eCT input rating: 5 A\u003c\/li\u003e\n  \u003cli\u003eCommunication: RS-485 Modbus\u003c\/li\u003e\n  \u003cli\u003eMounting: DIN rail\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.3 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGrid connection point monitoring on three-phase ESS installations with Victron Multi or Quattro inverter-chargers.\u003c\/li\u003e\n  \u003cli\u003eFeed-in and import measurement for three-phase grid-tied solar systems.\u003c\/li\u003e\n  \u003cli\u003eGenerator monitoring on sites with a three-phase generator and a Victron GX device.\u003c\/li\u003e\n  \u003cli\u003eAC load sub-metering to track consumption of specific circuits or buildings within a larger installation.\u003c\/li\u003e\n  \u003cli\u003eCommercial and industrial solar installations requiring per-phase energy data in the VRM portal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Energy Meter VM-3P5A (REL200320100)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe VM-3P5A must be installed by a qualified electrician. It connects to the AC distribution board via external current transformers and communicates with the GX device over a wired RS-485 connection. Correct CT orientation is required for accurate import and export readings. For grid-connected systems in the UK, the installation must comply with G98 or G99 requirements as applicable to the site. Current transformers are not included and must be sourced separately to match the site's cable size and current rating.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":55582880661795,"sku":"REL200320100","price":138.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0863\/9001\/4243\/files\/VoltaconSolar_-_REL200320100_-_Energy_Meter_VM-3P5A.webp?v=1789123385","url":"https:\/\/voltaconsolar.eu\/products\/victron-energy-meter-vm-3p5a","provider":"VoltaconSolar EU","version":"1.0","type":"link"}
