It connects to Victron GX devices and provides real-time energy data across all three phases, up to 65A per phase. It is suited to professional installers working on three-phase residential, commercial and off-grid installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-phase AC energy monitoring with a maximum current rating of 65A per phase.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron GX devices (Cerbo GX, Venus GX, Color Control GX) via RS485 connection.\u003c\/li\u003e\n  \u003cli\u003eCan be configured as a grid meter, PV inverter meter or generator meter within the Victron ecosystem.\u003c\/li\u003e\n  \u003cli\u003eSupports bidirectional measurement, allowing accurate monitoring of both import and export energy flows.\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable for clean, standard panel installation.\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.278 kg, with a compact form factor suitable for distribution boards and metering enclosures.\u003c\/li\u003e\n  \u003cli\u003eWorks 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 EM540 measures voltage, current, power factor, frequency and energy (kWh) on each of the three phases independently. When connected to a GX device, this data is displayed in the Victron console and logged to the VRM portal, giving installers and system owners a clear view of energy flows across the installation. The 65A per phase rating covers the majority of three-phase residential and light commercial applications without requiring external current transformers at lower loads.\u003c\/p\u003e\n\n\u003cp\u003eThe meter communicates over RS485 using the Modbus RTU protocol. It connects to the GX device via a VE.Can or USB-to-RS485 interface depending on the GX device in use. Correct addressing and wiring of the RS485 bus is important where multiple meters are installed on the same network. The EM540 replaces the older EM24 in most new installations and is the current recommended meter for three-phase monitoring within the Victron GX product range.\u003c\/p\u003e\n\n\u003cp\u003eWhen used as a grid meter, the EM540 enables ESS (Energy Storage System) functionality on compatible Victron Multi and Quattro inverter\/chargers, allowing the system to optimise battery charge and discharge against grid import and export. This is one of the primary use cases for this meter in UK and EU solar-plus-storage installations.\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;\"\u003eREL200100100\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;\"\u003eMaximum current\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e65A per phase\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCommunication\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eRS485 \/ Modbus RTU\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eMounting\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eDIN rail\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;\"\u003e0.278 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;\"\u003e8719076061168\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, Color Control GX and other Victron GX products\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 metering for three-phase Victron ESS installations, enabling accurate import\/export monitoring.\u003c\/li\u003e\n  \u003cli\u003ePV inverter monitoring on three-phase systems where a third-party inverter is present alongside Victron equipment.\u003c\/li\u003e\n  \u003cli\u003eGenerator metering to track fuel consumption and output in off-grid and hybrid systems.\u003c\/li\u003e\n  \u003cli\u003eThree-phase commercial solar-plus-storage installations requiring per-phase energy data.\u003c\/li\u003e\n  \u003cli\u003eRetrofit monitoring on existing three-phase distribution boards where energy visibility is needed.\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 EM540 (3-phase, 65A\/phase)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe EM540 must be installed by a qualified electrician. It connects directly in-line with the AC supply conductors, which involves working within a live distribution board. RS485 wiring to the GX device must be correctly terminated and addressed, particularly where multiple meters share the same bus. For grid-connected ESS systems in the UK, the overall installation must comply with G98 or G99 requirements as applicable. Do not exceed the 65A per phase rating; installations with higher load currents will require external current transformers and a compatible meter variant.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47442312364366,"sku":"REL200100100","price":84.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/energy-meter-em540-3-phase-max-65aphase-rel200100100-846609.jpg?v=1747937942","url":"https:\/\/voltaconsolar.com\/products\/victron-energy-meter-em540-3-phase-65a","provider":"VoltaconSolar","version":"1.0","type":"link"}
