Key Takeaways
- Remote firmware updates require a Victron GX device, internet connection, and specific VRM Portal settings.
- Always ensure the system is stable and not under critical load before initiating an update.
- An update failure can lead to configuration loss, especially for VE.Direct MPPT Charge Controllers.
- Do not attempt remote updates on products explicitly listed as "blacklisted" or not updatable.
How do I update my Victron device firmware remotely using the VRM Portal?
To update your Victron device firmware remotely, you need a Victron GX device (such as a Cerbo GX) connected to the internet and communicating with the VRM Portal. The "Full access" setting must be enabled in the GX device's VRM Online Portal menu. For firmware versions prior to v3.50, this setting is called "Two way communication." The VRM Portal provides the latest firmware files, so you typically do not need to upload them yourself.
Diagnosis and Preparation for Remote Firmware Update
Before initiating a remote firmware update, ensure your system meets the necessary conditions. This section outlines the checks and settings required.
- Verify GX Device Connection:
- Check: Confirm your Victron device is connected to a GX device (e.g., Cerbo GX).
- Meaning: This is a fundamental requirement for remote updates. Without a GX device, remote updates are not possible.
- Confirm Internet Connectivity and VRM Communication:
- Check: Ensure your GX device has an active internet connection and is successfully communicating with the VRM Portal.
- Meaning: The VRM Portal needs to send the firmware file to your GX device, which then relays it to the target Victron product. No internet, no update.
- Check VRM Portal Access Settings:
- Check: Navigate to the GX device menu → Settings → VRM Online Portal → VRM Portal. Verify that "Full access" is enabled.
- Check (for older firmware): If your GX device firmware is prior to v3.50, ensure "Two way communication" is enabled instead.
- Meaning: These settings grant the VRM Portal the necessary permissions to interact with your devices, including initiating firmware updates.
- Identify Updatable Devices:
- Check: Review the list of devices connected to your GX device on the VRM Portal.
Common Update Issues and Solutions
This table outlines common symptoms encountered during Victron VRM remote firmware updates, their likely causes, and recommended fixes.
Symptom detail | Likely cause | Fix |
|---|---|---|
Error 1341: Not updatable | The product is not a Victron device or is not recognized. | Verify the device is a genuine Victron product and properly connected. |
Error 1343: Not updatable: Blacklisted | The specific product cannot be updated remotely. | This product does not support remote firmware updates. Manual update might be an option, or no update is available. |
Configuration lost on VE.Direct MPPT Solar Charger after update failure | An unlikely update failure occurred on a VE.Direct connected MPPT. | Reconfigure the MPPT Solar Charger manually using VictronConnect or a local connection. |
BMV firmware update not possible | The BMV is connected via a canbus interface. | BMV devices connected via CANbus cannot be updated remotely. Use a direct connection for updates. |
Lynx Ion + Shunt 350 & 600A model (product-id 0xA130) firmware update not possible | The specific Lynx Ion + Shunt model (product-id 0xA130) is not remotely updatable. | This model cannot be updated remotely. |
Understanding Remote Firmware Update Capabilities
The Victron VRM Portal allows for remote firmware updates for a wide range of devices, streamlining maintenance and ensuring your system benefits from the latest features and bug fixes.
Devices Updatable via VE.Direct:
- MPPT Solar Charge Controllers (including MPPT RS)
- BMV Battery Monitors
- SmartShunts
- Inverter VE.Direct
- Smart IP43 Charger
- Orion XS
Devices Updatable via VE.Can:
- MPPT Solar Charge Controllers
- Skylla-i battery chargers
- Inverter RS
- Multi RS
- MPPT RS
Devices Updatable via VE.Bus:
- Multis
- Quattros
- Other VE.Bus-connected Inverter/chargers
The VRM Portal typically hosts all the latest firmware files, making it unnecessary for you to source them. However, there is an option to upload a firmware file from your computer if a specific version is required or if the portal does not have it.
Safety Considerations for Firmware Updates
Firmware updates, especially remote ones, carry inherent risks. Understanding these risks and taking precautions is crucial to maintain system stability and safety.
- General Advice: Victron's main advice is to avoid updating a running system unless there are specific problems that the update is intended to address.
- Configuration Loss: In the unlikely event of an update failure, VE.Direct MPPT Charge Controllers may lose their configuration. You would then need to reconfigure them manually.
When to call a technician instead
While remote firmware updates are convenient, some situations warrant professional intervention. If you encounter persistent errors like Error 1343 "Blacklisted" for a product you believe should be updatable, or if an update repeatedly fails and leads to system instability, it is best to contact a qualified Victron technician. Attempting to force an update or troubleshoot complex communication issues without proper training can void warranties or cause further damage to your equipment. If you are unsure about any step, or if your system is critical and cannot tolerate downtime, seek professional assistance.
Frequently asked questions
What are the requirements for a remote firmware update on the Victron VRM Portal?
Your Victron device must be connected to a GX device (such as a Cerbo GX) and have an active internet connection, communicating with the VRM Portal. The 'Full access' setting (or 'Two way communication' for older firmware) must be enabled in the GX device's VRM Online Portal settings.
What does Error 1341 mean during a Victron remote firmware update?
Error 1341 'Not updatable' typically indicates that the product you are attempting to update is not a Victron product or is not recognized as such by the VRM Portal.
What does Error 1343 mean during a Victron remote firmware update?
Error 1343 'Not updatable: Blacklisted' means the specific product you are trying to update cannot be updated remotely. Refer to the limitations for products that do not support remote updates.
Is it safe to update a running Victron system remotely?
Victron advises against updating a running system unless there are existing problems that the update is intended to fix. An update failure, though unlikely, can lead to configuration loss, especially for VE.Direct MPPT Charge Controllers.
