• Inspect the VE.Can port, are there bent pins? If this is the case use long nose pliers to straighten the pins when the solar
charger is unpowered.
• Check if the first and the last device on the VE.Can chain have their terminators placed.

9.6.4. VE.Smart communication issues
A VE.Smart Network is a wireless communication network between several Victron products using Bluetooth. In case of issues
with a VE.Smart Network refer to the Smart Network manual.
9.6.5. Bluetooth issues
Please note that it is highly unlikely that the Bluetooth interface is faulty. The problem is most likely caused by something else.
Use this chapter to quickly rule out some of the common causes of Bluetooth issues.
For a full troubleshooting guide see the VictronConnect manual.
• Check if the solar charger is equipped with Bluetooth
Only SmartSolar models have built-in Bluetooth, the BlueSolar models do not. If the model does not have built-in Bluetooth, a
VE.Direct Bluetooth Smart dongle or VE.Direct to USB interface can be used.
• Check if Bluetooth is enabled
It is possible to enable/disable Bluetooth in the product settings. To re-enable:
Connect to the solar charger via the VE.Direct port.
Navigate to the controller settings and then to "product info".
Re-enable Bluetooth.
• Check if the controller is powered-up
Bluetooth is active as soon as the solar charger is powered-up.
This can be checked by looking at the LEDS:
If all LEDs are off, the unit is not powered up.
If any of the LEDs are on, blinking or pulsing with a few seconds interval, the unit is powered-up and Bluetooth should be
functional.
• Check that Bluetooth is in range
In open space the maximum Bluetooth distance is about 20 meters. In a build-up area, inside a house, a shed, a vehicle or a
boat this distance can be a lot less.
• The Windows VictronConnect app does not support Bluetooth
The Windows version of the VictronConnect app does not support Bluetooth. Use an Android, iOS or macOS device instead. Or
alternatively connect using a VE.Direct to USB interface.
• The controller is missing in the VictronConnect device list
