It connects to Victron GX devices and provides real-time consumption, production and import\/export data across all three phases. Suitable for professional installers integrating Victron systems into three-phase residential, commercial or industrial installations.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-phase energy monitoring with a maximum measurement current of 65A per phase.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron GX devices (Cerbo GX, Color Control GX, Venus GX) via RS-485 Modbus communication.\u003c\/li\u003e\n  \u003cli\u003eMeasures both import and export energy, making it suitable for grid-tied solar installations with feed-in monitoring.\u003c\/li\u003e\n  \u003cli\u003eCan be used as a grid meter, PV inverter meter or load meter within the Victron ecosystem.\u003c\/li\u003e\n  \u003cli\u003eDIN rail mounting for straightforward installation inside a distribution board or enclosure.\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.23 kg, with a compact form factor suited to standard electrical enclosures.\u003c\/li\u003e\n  \u003cli\u003eSupports multiple meter roles simultaneously when used alongside other Victron monitoring hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe ET340 connects to a Victron GX device over RS-485 using the Victron USB to RS-485 interface cable (sold separately). Once connected, the GX device reads energy data from the meter and displays it in the VRM portal and on local GX displays. This allows installers and system owners to track grid consumption, solar yield and load behaviour in real time and historically.\u003c\/p\u003e\n\n\u003cp\u003eThe 65A per phase rating covers the majority of three-phase residential and light commercial installations without the need for external current transformers, simplifying wiring and reducing installation time. For higher-current applications, external CTs are required and the meter must be sized accordingly. The ET340 is specifically designed for use within the Victron ecosystem and is not a standalone energy monitor.\u003c\/p\u003e\n\n\u003cp\u003eWhen deployed as a grid meter, the ET340 enables ESS (Energy Storage System) functionality on compatible Victron systems, allowing the system to respond to grid import and export in real time. This is a key requirement for any Victron ESS installation on a three-phase supply.\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;\"\u003eREL300300000\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 per phase\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e65A\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;\"\u003eRS-485 Modbus\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;\"\u003e0.23 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;\"\u003e8719076039693\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 in three-phase Victron ESS installations to enable import\/export control.\u003c\/li\u003e\n  \u003cli\u003eMonitoring AC output of third-party three-phase PV inverters connected to a Victron system.\u003c\/li\u003e\n  \u003cli\u003eLoad monitoring on three-phase distribution boards in commercial or industrial premises.\u003c\/li\u003e\n  \u003cli\u003eThree-phase solar installations in light commercial buildings where per-phase consumption data is required.\u003c\/li\u003e\n  \u003cli\u003eRetrofit monitoring in existing three-phase installations being upgraded with Victron GX equipment.\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 ET340 (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 ET340 must be installed by a qualified electrician. It is a direct-connect meter rated to 65A per phase; installations exceeding this current require appropriately rated current transformers. Connection to a Victron GX device requires a USB to RS-485 interface cable, which is not included. Ensure the GX device firmware is up to date to guarantee full ET340 compatibility. For grid-connected ESS systems in the UK, the overall installation must comply with G98 or G99 requirements as applicable.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47442225234254,"sku":"REL300300000","price":63.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-energy-meter-et340-3-phase-max-65aphase-rel300300000-591173.jpg?v=1747937816","url":"https:\/\/voltaconsolar.com\/products\/victron-energy-meter-et340-3-phase-65a","provider":"VoltaconSolar","version":"1.0","type":"link"}
