5. 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.

5.1. Power issues

The display is powered via the VE.Direct cable or via the power cable. If the display does not power up check these cables.

VE.Direct cable check:
  1. Check if the VE.Direct is plugged into the back of the display

  2. Check if the VE.Direct cable is plugged into the solar charger

  3. Make sure the VE.Direct connectors are inserted all the way into the VE.Direct ports.

  4. Check the VE.Direct port pins; ensure that they are not damaged, bend or missing.

  5. Check if the solar charger is able to provide power via the VE.Direct cable when no PV input (at night). Some very early solar chargers models, that have been since long discontinued need to have the power cable installed.

Power cable check
  1. Check the fuse in the power cable.

  2. Check if the power cable is plugged into the back of the display.

  3. Check if the power cable is connected to the battery or to another supply voltage.

  4. Check if the supply voltage is between 6.5 and 95 Vdc.

5.2. Settings locked

If the setup menu is locked settings can only be viewed but not changed. When trying to change the setting the word LOCK is shown.

To unlock the settings menu see the instruction in the Settings menu chapter.
