9. Troubleshooting and Support

In this section:

Consult this chapter in case of unexpected behaviour or if you suspect a product fault.

The correct troubleshooting and support process is to first consult the common issues as described in this chapter.

Should this fail to resolve the issue, contact the point of purchase for technical support. If the point of purchase is unknown, refer to the Victron Energy Support webpage.

9.7. Settings or firmware issues

9.7.1. Incorrect settings

Incorrect settings can cause strange solar charger behaviour. Check if all settings are correct.

If in doubt, it could be an option to reset all settings to default using the VictronConnect app and then make all required settings. Consider saving the existing settings before performing a reset.

In most cases the default setting can be used with only minor changes.

If help is required with making settings, please refer to the manual or contact your Victron supplier or distributor.

9.7.2. Unable to select 36V or 48V battery voltage

Not all solar chargers support 36V or 48V battery system voltages.

The drop-down menu in the VictronConnect App will display the supported battery voltages.

9.7.3. Firmware issues

To rule out a firmware bug, update the firmware.

NOTE: It might be useful to write down the firmware number before and after the update. This can be usefull information should you need to request support.

On first connection, the controller might have updated the firmware. If the controller did not automatically ask for a firmware update, check if the controller is running the most up to date firmware and perform a manual update:

  • Connect to the controller.

  • Click on the settings symbol setting-cog.png .

  • Click the option symbol option-symbol.png.

  • Go to product info.

  • Check if you are running the latest firmware and look for the text: “This is the latest version”.

  • If the controller does not have the most up to date firmware, perform a firmware update by pressing the update button.

9.7.4. Interrupted firmware update

This is recoverable and is nothing to worry about. Just try to update the firmware again.
