{"product_id":"victron-interface-mk3-usb","title":"Victron Interface MK3-USB","description":"\u003cp\u003eThe Victron Interface MK3-USB and MK3-USB-C are essential configuration and firmware update tools that connect any Victron VE.Bus inverter or inverter\/charger to a Windows, macOS, or Android computer or smartphone via USB. The only functional difference between the two variants is the computer-side connector- the MK3-USB (ASS030140000) uses a standard USB-A plug, while the MK3-USB-C (ASS030140030) uses a USB-C plug for compatibility with modern laptops and tablets that lack USB-A ports. Both variants use an identical RJ45 VE.Bus connector on the inverter side and provide the same full VE.Bus configuration and firmware update capability.\u003c\/p\u003e\n\u003cp\u003eThe MK3 interface is required for initial parallel, three-phase, and split-phase configuration of VE.Bus inverter\/charger systems - tasks that can only be performed via a direct MK3 connection and cannot be completed via VRM, a GX device, or any other remote interface. It is also required for firmware updates to VE.Bus products and for advanced configuration using VE.Configure on Windows - the most comprehensive configuration tool for Victron MultiPlus, Quattro, and Phoenix VE.Bus inverters.\u003c\/p\u003e\n\u003cp\u003eThe interface connects to the RJ45 VE.Bus port on the inverter or inverter\/charger using a standard factory-made UTP (Ethernet) patch cable - not included, and must be purchased separately. Victron's documentation specifically warns against using hand-crimped RJ45 cables, which frequently cause communication failures even when otherwise functional for network use. On the computer side, the MK3 is recognised automatically by VictronConnect on Windows, macOS, and Android without driver installation - however it does not work with iOS (iPhone or iPad).\u003c\/p\u003e\n\u003cp\u003eFor day-to-day settings changes such as charge voltages, AC input current limits, and PowerAssist parameters, a GX device with VRM access can be used instead. The MK3 is typically needed only during initial system commissioning, when adding inverters to an existing parallel or three-phase system, or when performing firmware updates on VE.Bus products.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003ch4\u003eRequired for VE.Bus System Configuration and Firmware Updates\u003c\/h4\u003e\n\u003cp\u003eThe only interface that enables initial parallel, three-phase, and split-phase phase assignment - tasks that cannot be performed via VRM, GX device, or any other remote method.

On Windows, VE.Configure provides the most comprehensive parameter configuration capability for VE.Bus inverter\/charger systems. Not compatible with iOS (iPhone or iPad).\u003c\/p\u003e\n\u003ch4\u003eNo Driver Installation Required\u003c\/h4\u003e\n\u003cp\u003eBoth MK3 variants are recognised automatically by VictronConnect and VE.Configure on current Windows, macOS, and Android operating systems without manual driver installation - enabling immediate connection and use after plugging in.\u003c\/p\u003e\n\u003ch4\u003eRJ45 UTP Cable Required - Not Included\u003c\/h4\u003e\n\u003cp\u003eA factory-made UTP patch cable with RJ45 connectors is required to connect the MK3 interface to the inverter's VE.Bus port - sold separately. Victron strongly recommends using a factory-crimped cable rather than a hand-crimped field cable, as hand-crimped cables frequently cause intermittent communication failures during configuration sessions.\u003c\/p\u003e\n\u003ch4\u003eBus-Powered - No External Power Required\u003c\/h4\u003e\n\u003cp\u003eBoth MK3 variants are powered entirely from the computer's USB port - no separate power supply, battery connection, or mains power is required for the interface itself to operate.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"product-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMK3-USB\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMK3-USB-C\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eASS030140000\u003c\/td\u003e\n\u003ctd\u003eASS030140030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVE.Bus Connector\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eRJ45 (male)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComputer Connector\u003c\/td\u003e\n\u003ctd\u003eUSB-A\u003c\/td\u003e\n\u003ctd\u003eUSB-C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Products\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eMulti, MultiGrid, MultiPlus, MultiPlus-II, Quattro, Phoenix VE.Bus, VE.Bus BMS V2, ECOmulti, EasySolar, EasyPlus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Software\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eVictronConnect (Windows \/ macOS \/ Android) | VE.Configure (Windows only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eiOS (iPhone \/ iPad) Compatible\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Installation Required\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eBus-powered from USB host port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRJ45 Cable Required\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003eYes - factory-made UTP cable (not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e0.08 kg (approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eManuals\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/VictronConnect_configuration_guide_for_VE.Bus_products\/15296-VE_Bus_Configuration_guide-pdf-en.pdf\" target=\"_blank\"\u003eVictronConnect configuration guide\u003c\/a\u003e\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Victron Interface MK3-USB-C","offer_id":47125541060857,"sku":"IVV80015","price":65.45,"currency_code":"USD","in_stock":true},{"title":"Victron Interface MK3-USB","offer_id":47125541028089,"sku":"IVV80011","price":75.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/8538\/1625\/files\/Product-IVV80011-1.webp?v=1780453562","url":"https:\/\/emarineinc.com\/products\/victron-interface-mk3-usb","provider":"eMarine","version":"1.0","type":"link"}
