Victron VRM Remote VEConfigure: A Guide to Remote System Configuration

Key Takeaways

• Ensure your GX device is correctly installed, powered directly from the battery, and has "Full access" enabled in the VRM Portal settings.
• Verify all firmware versions (VE.Bus, GX device Venus OS, VE.Bus to VE.Can interface) meet the minimum requirements for remote configuration.
• Be aware that changing certain settings, especially Assistant configurations, will momentarily switch off your VE.Bus system.
• If you encounter persistent communication issues, complex firmware update challenges, or are unsure about the impact of configuration changes, contact a qualified Victron technician.

How do I configure my Victron system remotely using VRM?

Remote configuration of your Victron system via the VRM Portal allows you to adjust settings for your MultiPlusses, Quattros, and other VE.Bus products from anywhere with an internet connection. The most common cause of issues is incorrect setup of the GX device or outdated firmware versions. The first thing to check is that your GX device is properly installed and communicating with the VRM Portal.

Diagnosis

Follow these steps to diagnose issues with Victron VRM Remote VEConfigure:

1. Verify GX Device Installation and Power:

• • Check: Ensure a GX device (e.g., Cerbo GX) is physically installed at the system location. Confirm it is powered directly from the battery, not from an AC adapter connected to the inverter/charger's AC output.
  • Meaning: The GX device is essential for VRM communication. Powering it from the inverter's AC output can cause it to lose power when the inverter momentarily switches off during configuration, disrupting the process.

2. Confirm Internet Connection and VRM Portal Communication:

• • Check: Verify that the GX device has a stable internet connection and is actively communicating data to the Victron VRM Portal. You should see live data from your system on the VRM Portal.
  • Meaning: Remote VEConfigure relies entirely on a continuous internet connection between the GX device and the VRM Portal. No connection means no remote configuration.

3. Inspect "Full Access" Setting on GX Device:

• • Check: On the GX device menu, navigate to Settings → VRM Online Portal → VRM Portal and confirm that the "Full access" setting is enabled.
  • Meaning: This setting grants the necessary permissions for the VRM Portal to initiate remote configuration sessions. Without it, remote VEConfigure will not function.

4. Review VE.Bus Firmware Version:

• • Check: Determine the firmware version of your MultiPlus, Quattro, or other VE.Bus product.
  • Meaning: VE.Bus firmware versions 416 and 417 are specifically noted as incompatible with remote configuration. For remote configuration to work, the VE.Bus firmware must be version 418 or later.

5. Examine GX Device Venus OS Version:

• • Check: Identify the Venus OS version running on your GX device.
  • Meaning: Remote configuring VE.Bus firmware version 418 or later requires the GX device to run Venus OS v2.10 or later. For certain advanced features, such as replacing a unit without full reconfiguration, Venus OS v2.62 or later is needed. The latest official version is generally preferred.

6. Check VE.Bus to VE.Can Interface Firmware (if applicable):

• • Check: If your system uses a VE.Bus to VE.Can interface cable, verify its firmware version.
  • Meaning: This interface cable needs to run firmware version v2.05 or higher for proper remote configuration functionality.

7. Observe System Behavior During Configuration Attempts:

• • Check: Note if the system momentarily switches off or if the internet connection drops when attempting to change settings, particularly Assistant configurations.
  • Meaning: This is expected behavior for certain setting changes. If your internet equipment is AC-powered by the inverter, the temporary shutdown will also affect its power, leading to a connection loss.

Requirements and Process for Remote VEConfigure

Remote VEConfigure is a powerful feature that allows you to manage your Victron system's settings without needing to be physically present. To use it effectively, several conditions must be met, and the process involves specific steps.

System Requirements

Before attempting remote configuration, ensure your system meets these requirements:

• GX Device: A GX device (such as a Cerbo GX) must be installed locally on your system. This device acts as the communication bridge between your Victron products and the VRM Portal.
• GX Device Power: The GX device must be powered directly from the battery. Powering it from an AC adapter connected to the inverter/charger's AC output can lead to communication loss during system reconfigurations.
• Internet Connection: Your system must have a stable internet connection, and the GX device must be actively communicating data to the VRM Portal.
• VRM Portal Access: The "Full access" setting must be enabled on your GX device. You can find this under GX device menu → Settings → VRM Online Portal → VRM Portal.
• Firmware Versions:
• • VE.Bus Firmware: Your MultiPlus, Quattro, or other VE.Bus product must have firmware version 418 or later. Firmware versions 416 and 417 cannot be configured remotely.
  • GX Device Venus OS: The GX device must be running Venus OS v2.10 or later to configure VE.Bus firmware 418+. For optimal performance and specific features (like replacing a unit without full reconfiguration), Venus OS v2.17 or later (or v2.62 or later for the unit replacement feature) is recommended.
  • VE.Bus to VE.Can Interface: If used, this interface cable requires firmware version v2.05 or higher.

The Remote Configuration Process

Once all requirements are met, you can proceed with remote configuration:

1. Prepare Configuration File: Use VE.Config software on your computer to create or modify your system's configuration. Save this file in the .RVSC format. This is the only file type that can be uploaded via Remote VEConfigure.
2. Upload to VRM Portal: Access your system's page on the VRM Portal. Navigate to the Remote VEConfigure section and upload your .RVSC file.
3. System Protection: The VRM Portal includes a safety mechanism that compares the serial numbers of the installed inverter/chargers against those in your configuration file. This prevents accidentally applying settings from one system to another. For systems with multiple inverter/chargers, if Venus OS v2.62 or later is installed, the mechanism can even accept up to one exchanged serial number and adjust automatically.
4. Time Considerations:

• • Reading settings from the device takes approximately 85 seconds per unit. If VEConfigure Assistants are used, this process will take longer.
  • Writing Assistant configurations can take anywhere from a few seconds to 40 seconds per unit.

5. System Behavior: Be aware that changing certain settings, such as Assistant configurations, will cause the VE.Bus system to momentarily switch off during the reconfiguration process. If your internet equipment is powered by the inverter's AC output, this will also temporarily interrupt your internet connection. VE.Config will typically provide warnings for settings that cause a system shutdown.

Safety: Momentary System Shutdowns

When using Remote VEConfigure, especially when changing certain settings like Assistant configurations, the VE.Bus system will momentarily switch off. This is a normal part of the reconfiguration process. If your internet communication equipment (e.g., router) is powered by the AC output of your inverter/charger, it will also lose power during this brief period, leading to a temporary loss of internet connectivity. Ensure that any critical loads are either on a separate, uninterruptible power supply or can tolerate a brief power interruption.

When to call a technician instead

While Remote VEConfigure offers significant convenience, there are situations where professional assistance is recommended. If you encounter persistent communication failures that you cannot resolve, or if you are unsure about the implications of specific configuration changes, especially those involving complex Assistants or firmware updates, it is best to contact a qualified Victron Energy technician. They can provide expert diagnosis and ensure your system is configured safely and correctly.
