Genuine Victron VE.Bus programming interface
Configure, update, and diagnose compatible Victron VE.Bus equipment from a modern USB-C computer or supported Android device.
The Victron MK3-USB-C interface is the modern VE.Bus to USB-C bridge for installers commissioning MultiPlus, MultiPlus-II, Quattro, and other supported Victron VE.Bus products. Part ASS030140030 connects directly to USB-C hardware for access to VictronConnect configuration, firmware updates, and diagnostics without adding a USB-A conversion dongle to a compatible MacBook, Windows PC, or USB-host-capable Android device.
A direct physical connection for current MacBooks, USB-C PCs, and supported Android hardware.
New laptops often omit the rectangular USB-A port found on the original MK3-USB interface. The MK3-USB-C removes that physical mismatch by presenting a native USB-C connection while translating data to and from the Victron VE.Bus network.
The MK3 component in VictronConnect is supported on Windows, macOS, and Android. Android phones and tablets must support USB host or OTG operation, and Apple iPhone and iPad devices are not supported for a wired MK3 connection even when the device has a USB-C port.
Connect the USB-C end to a compatible Mac or Windows computer and use VictronConnect for supported VE.Bus settings, monitoring, firmware updates, and diagnostics. Windows systems connected to the internet normally obtain the MK3 driver automatically; offline systems may require Victron's driver installer.
VictronConnect supports MK3 configuration on Android. The phone or tablet must support USB host / OTG data operation, and the Victron VE.Bus product must be powered. Device-specific USB behavior varies, so confirm compatibility before relying on a mobile device for commissioning.
The professional interface between supported Victron equipment and configuration software.
VictronConnect supports the MK3 on Windows, macOS, and Android for compatible status, settings, firmware-update, and diagnostic workflows. It is the preferred modern interface for many routine VE.Bus commissioning tasks.
VEConfigure remains Windows-only and may be required for advanced or legacy functions that VictronConnect does not yet provide, such as certain Assistants, grid-code changes, Virtual Switch functions, lithium workflows that require an Assistant, or external-current-sensor setup.
Enter approved lithium settings, update firmware, and commission complex VE.Bus systems.
Exact-match details for Victron part ASS030140030.
Victron identifies VE.Bus configuration as a powerful installer function. Incorrect inverter, charger, grid, generator, battery, or multi-unit settings can damage equipment or create an unsafe installation. Back up the existing configuration, follow the current Victron manual, use the battery manufacturer's approved parameters, and involve a trained Victron installer when the system includes managed lithium batteries, Assistants, grid codes, parallel units, split phase, three phase, or other advanced functions. Firmware updates may reset settings to factory defaults.
Frequently asked questions
Choose ASS030140030 when the computer or supported Android device you plan to use has a USB-C data port. Choose the USB-A MK3 version when your service computer uses the older rectangular USB-A port. Both perform the VE.Bus interface function; the difference is the host-side USB connector.
A factory-manufactured straight-through RJ45 UTP cable is required between the MK3 interface and the VE.Bus port on the Victron product. The current Epoch listing identifies the interface but does not list an RJ45 cable in the package contents, so plan to provide a compatible Victron RJ45 UTP cable separately unless you already have one.
Yes. VictronConnect supports the MK3 interface on Windows, macOS, and Android. A modern Mac or PC can use the USB-C connection directly when the port supports data. An Android phone or tablet must support USB host / OTG operation, and compatibility should be confirmed for the exact device.
No. Victron's current documentation states that the wired MK3 component is available for Android, Windows, and macOS, but not iOS. A USB-C connector on an iPhone or iPad does not make the MK3 configuration workflow supported. Use a documented Victron alternative for Apple mobile monitoring.
Use VictronConnect on Windows, macOS, or supported Android devices for compatible status, settings, firmware-update, and diagnostic functions. VEConfigure is Windows-only and remains necessary for certain advanced or legacy functions that are not available in VictronConnect. Check the current Victron guide for your exact product and task.
Victron lists Multi, MultiGrid, MultiPlus, MultiPlus-II, Quattro, VE.Bus BMS V2, the inverter/charger section of supported ECOmulti, EasySolar and EasyPlus products, and inverters equipped with a VE.Bus communication port. Available functions depend on the exact model and firmware generation.
The MK3-USB-C gives you access to supported VE.Bus charger and inverter settings. Enter only the exact charging parameters and system settings published for the specific Epoch battery, and follow the required BMS or CAN communication design. The MK3 interface itself does not create battery-to-Victron CAN communication and does not replace a battery-specific communications cable.
No. The MK3 is for documented VE.Bus products. SmartSolar charge controllers, SmartShunts, BMV monitors, and other VE.Direct devices use Bluetooth, a VE.Direct cable, or a VE.Direct-to-USB interface depending on the model and installation.
Usually not. The MK3 is primarily a commissioning, configuration, firmware, and troubleshooting interface. After setup, disconnect it and store it with your service tools. For permanent monitoring and remote access, use the appropriate Victron GX device or another documented monitoring accessory.
Verify the Victron model, VE.Bus port, firmware generation, computer platform, required software, RJ45 cable, battery settings, and installer permissions before commissioning. Do not connect the MK3 to VE.Direct or battery CAN ports, and do not substitute a crossover cable for the required straight-through RJ45 UTP connection.
