It links to a Victron GX device and reports real-time consumption, production and import\/export data across all three phases, making it a core part of a three phase victron energy meter setup for professional installers.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement range\u003c\/strong\u003e, three-phase monitoring up to 65A per phase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication\u003c\/strong\u003e, connects to Victron GX devices (Cerbo GX, Color Control GX, Venus GX) via RS-485 Modbus.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImport\/export metering\u003c\/strong\u003e, suited to grid-tied solar installs with feed-in monitoring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible role\u003c\/strong\u003e, can be configured as a grid meter, PV inverter meter or load meter within the Victron ecosystem.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e, DIN rail fitting for a distribution board or enclosure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 0.23 kg, compact enough for standard enclosures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe ET340 connects to a Victron GX device over RS-485 using the Victron USB to RS-485 interface cable, sold separately. Once wired in, the GX device pulls energy data from the meter for display in the VRM portal and on local GX screens, giving a record of grid use, solar yield and load behaviour over time.\u003c\/p\u003e\u003cp\u003eIts 65A per phase rating covers most three-phase residential and light commercial jobs without needing external current transformers. Higher-current sites will need CTs and a meter sized to match. As a grid meter it enables ESS functionality on compatible Victron systems responding to grid import and export, which is required for a three-phase ESS installation.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGrid metering in three-phase Victron ESS installations for import\/export control.\u003c\/li\u003e\n\u003cli\u003eMonitoring output from third-party three-phase PV inverters on a Victron system.\u003c\/li\u003e\n\u003cli\u003eLoad monitoring on three-phase distribution boards in commercial or industrial sites.\u003c\/li\u003e\n\u003cli\u003eRetrofitting existing three-phase installations being upgraded with Victron GX equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Energy Meter ET340 (3-phase, 65A\/phase)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting must be carried out by a qualified electrician. This is a direct-connect meter rated to 65A per phase; higher currents need appropriately rated CTs. A USB to RS-485 interface cable is required to link to a GX device and is not included. Keep GX firmware updated for full compatibility, and for grid-connected ESS systems in the UK, follow G98 or G99 requirements as applicable.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52060517466400,"sku":"REL300300000","price":60.47,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-rel300300000-1.webp?v=1785491424","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-et340-three-phase-energy-meter","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
