MK3-USB-C (VE.Bus to USB-C) MK2

The Victron Energy MK3-USB-C interface (VE.Bus to USB-C) is a tool designed for configuring, monitoring, updating firmware, and diagnosing Victron products equipped with a VE.Bus port. It enables a wired connection between your VE.Bus device and a compatible computer or mobile device.

The main features of the MK3-USB-C interface include:

Configuring Victron energy system parameters.Updating Victron product firmware without requiring an internet connection.Monitoring real-time data.Diagnosing potential issues on VE.Bus products.It is an ideal tool for installers to efficiently configure systems after wiring.

The MK3-USB-C interface is primarily used with the VictronConnect application. This app is designed to gradually replace VEConfigure and VEFlash software, providing a more intuitive interface and multiplatform compatibility.

No, the MK3-USB-C interface does not require an internet connection to perform firmware updates or configure Victron products. Simply connect the interface to the product and your compatible device.

The MK3-USB-C interface is compatible with Android, Windows, and macOS X operating systems.

No, the MK3-USB-C interface is not compatible with iOS devices (iPhone/iPad).

The interface is compatible with a wide range of Victron products equipped with a VE.Bus communication port, including:

MultiPlus (including Compact)MultiPlus-IIMultiPlus-II GXMultiGridQuattrosEasySolarEasySolar-IIEasySolar-II GXPhoenix inverters equipped with a VE.Bus port

For full functionality (data reading, parameter modification, firmware update), VE.Bus products must have firmware version 415 or higher. These products are identifiable by a 7-digit software number on a label, where the first two digits start with 26 or 27.

For VE.Bus products equipped with an old microcontroller (software number starting with 19 or 20), the minimum supported firmware version is 19xx200 for European units and 20xx200 for 120V models. In this case, compatibility is limited to data reading; parameter modification or firmware updates are not possible.

No, older VE.Bus products, such as those with firmware numbers starting with 18xxxxx, are not supported by the MK3-USB-C interface.

The VictronConnect application, used with the MK3-USB-C interface, gradually replaces VEConfigure and VEFlash for most tasks. However, some advanced features still require the use of VEConfigure. These include:

Assistants (e.g., AC PV, ESS).Full functionality of the Virtual Switch (though some functions are available via AC input control).Network code modification.Lithium Battery Wizard (for lithium battery types requiring the installation of an assistant, such as the VE.Bus BMS).Support for the external current sensor on Multiplus-II units.

The MK3-USB-C interface is used for full configuration, parameter modification, and firmware updates of VE.Bus products via a wired USB connection. The VE.Bus Smart dongle, on the other hand, allows reading status data, voltages, and other information, as well as basic operations such as controlling the input current limit or enabling/disabling the inverter via Bluetooth. The Smart dongle does not allow parameter modification or firmware updates.

To connect the MK3-USB-C interface, plug one end into the Victron device with a VE.Bus port and the other end (USB-C) into your computer or compatible mobile device. Once connected, you can use the VictronConnect app to interact with the device.

Yes, the configuration features provided by this tool are powerful and intended for use by Victron-trained engineers, installers, and dealers. Victron does not provide direct support to untrained individuals performing configuration.

Yes, the configuration settings are password-protected. This password is provided during Victron training. For more information, contact your Victron distributor.

Yes, the MK3-USB-C interface can be used to configure systems composed of multiple units, such as parallel, three-phase, or split-phase systems, by following the appropriate configuration procedures with the VictronConnect application.

The VictronConnect application, once connected to your VE.Bus product via the MK3-USB-C interface, will generally indicate whether a firmware update is available or recommended. It is advisable to check for updates regularly to benefit from the latest improvements and fixes.

Yes, it is important to note that a firmware update may reset the device settings to factory defaults. Therefore, it is recommended to back up your current settings before updating, if this option is available in VictronConnect. Also ensure the connection remains stable throughout the process to avoid any interruption.

If you experience connection or configuration issues, first check the following:

Compatibility of your Victron device (firmware version).Compatibility of your operating system (Android, Windows, macOS X).Proper physical connection of the interface between the VE.Bus product and your device.If the issues persist and you are a trained installer, you can refer to the VictronConnect configuration guide for VE.Bus products or contact your Victron distributor for assistance.

The Victron Energy MK3-USB-C interface (VE.Bus to USB-C) is an essential tool for configuring, monitoring, updating, and diagnosing Victron products equipped with a VE.Bus communication port.
