Victron VEConfigure Assistants Overview: How to Add and Configure

Key Takeaways

• Victron VE.Bus devices, such as Multis, Inverters, and Quattros, require specific firmware to use Assistants.
• Configuration of Assistants is performed using the VEConfigure3 software on a connected computer.
• The inverter/charger will temporarily switch off and then restart when new Assistant settings are sent to the unit.
• Always ensure you have the correct firmware and understand the intended function of each Assistant before deployment.

How do you add and configure Victron VEConfigure Assistants?

You add and configure Victron VEConfigure Assistants by connecting your computer to a compatible Victron VE.Bus device and using the VEConfigure3 software. This process involves selecting and customizing specific software modules to extend the functionality of your inverter/charger.

Configuration Steps for VEConfigure Assistants

To add and configure an Assistant, follow these steps using the VEConfigure3 software:

1. Open VEConfigure3 Software: Start the VEConfigure3 application on your computer.
2. Connect to Victron Product: Establish a connection between your computer and the Victron VE.Bus device (Multi, Inverter, or Quattro).
3. Access Assistants Tab: Navigate to the "Assistants" tab within the VEConfigure3 interface.
4. Select and Add Assistant: From the available drop-down menu, choose the desired Assistant, such as "Grid Converter support" (now known as "PV Inverter support"). Then, click "add assistant" to include it in your configuration.
5. Start Assistant Configuration: Click on "Start assistant" to begin customizing its settings.
6. Configure Assistant Settings: Adjust the user-defined settings for the selected Assistant. For example, you might set the "Grid Inverter switch-off frequency" or the "Total PV power installed" in Watts. Other settings like "Battery type" or "Charger settings" can also be defined here or pulled from the Charger page. The "Restart voltage" can be user-defined, though it is not recommended to change this unless necessary.
7. Send Settings to Device: Once configuration is complete, select "send settings" to transfer the new Assistant setup to your Victron unit.
8. Device Restart: The Inverter/Charger will switch off while sending the assistant setup to the unit. After the transfer, the Inverter/Charger will restart. If prompted, confirm "OK" to complete the restart process.

Key Settings for VEConfigure Assistants

The following table outlines common settings you might encounter when configuring Assistants in VEConfigure3:

Understanding VE.Bus Firmware and Assistants

For VE.Bus Multis, Inverters, and Quattros to work with Assistants, they must be loaded with a specific, different firmware. This firmware enables the device to interpret and execute the instructions provided by the Assistants. Without the correct firmware, Assistant functionality will not be available. The process of updating firmware is not detailed here, but it is a prerequisite for Assistant use.

Victron Energy offers various Assistants, each designed for a specific function. Examples include:

• ESS Assistant: For Energy Storage Systems, managing battery charging and discharging based on grid conditions and self-consumption.
• PV Inverter support: Integrates grid-tied PV inverters with the Victron system.
• Generator start and stop Assistant: Automates generator operation based on battery state or load.
• AC Current sensor Assistant: Utilizes an AC current sensor for monitoring and control.
• Charge current control Assistant: Manages battery charge currents.
• VE.Bus BMS support Assistant: Facilitates communication and control with Victron's Battery Management System.

These Assistants allow for highly customized system behavior, optimizing energy flow and system performance according to specific requirements.

Safety Considerations

The provided documentation for VEConfigure Assistants does not detail specific safety facts related to the software configuration process itself. However, when working with any solar power system components, general electrical safety practices should always be observed. This includes ensuring power is disconnected before making physical connections, using insulated tools, and being aware of high voltages and currents present in the system.

When to call a technician instead

While configuring Assistants is a software-based task, complex system integrations or persistent issues may require professional assistance. You should call a qualified technician if:

• You are unsure about the correct firmware version required for your specific VE.Bus device to support Assistants.
• The VEConfigure3 software fails to connect to your device or consistently reports errors during configuration.
• The inverter/charger does not restart correctly after sending Assistant settings, or exhibits unexpected behavior.
• You are attempting to configure an Assistant for a critical system function and are uncertain about the implications of specific settings.
• The system's overall performance degrades or becomes unstable after Assistant configuration, and you cannot resolve it by reverting settings.

A technician can help diagnose underlying hardware or firmware issues, ensure correct configuration, and verify system stability, especially for systems under warranty where improper configuration might void terms.
