The Victron MK3-USB-C Interface is the modern programming and service interface for Victron VE.Bus inverter/chargers. Designed for today's USB-C equipped laptops, tablets, and compatible Android devices, it creates a direct connection between your device and the VE.Bus communication port, allowing installers and advanced users to configure system settings, perform firmware updates, troubleshoot issues, and commission new installations.
Compatible with VE.Configure, VEFlash, and VictronConnect, the MK3-USB-C provides full access to the advanced features of Victron VE.Bus products. While VictronConnect continues to expand its capabilities, VE.Configure remains the preferred software for many advanced configuration tasks, making the MK3-USB-C an indispensable tool for professional installers and experienced DIY builders alike.
