VE.Bus Smart Dongle

Q: I only see a battery page screen in the VictronConnect app, but I do not see inverter/charger pages.

A: The dongle is not communicating with the inverter/charger. Check if it is plugged into the inverter/charger via an RJ45 UTP cable. Or, if it is plugged in, check the integrity of the RJ45 cable.

Q: I cannot see the inverter/charger data; only the battery data is displayed in the VictronConnect app.

A: Check if the inverter/charger has been turned on via its main switch, and check if the dongle is plugged into the inverter/charger via an RJ45 UTP cable. Or, if it is plugged in, check the integrity of the RJ45 cable.

Q: Can the dongle be used together with the Digital Multi Control panel (DMC)?

A: Yes, but in this scenario, the dongle cannot switch the inverter/charger to on, off or to charger-only, only the DMC can.

Q: Can the dongle be used together with a VE.Bus BMS?

A: Yes, but in this scenario, the dongle cannot switch the inverter/charger to on, off or to charger-only, only the VE.Bus BMS can. If full functionality of the dongle is required, use a VE.Bus BMS V2 instead.

Q: It is not possible to change the AC current limit.

A: Update the inverter/charger firmware to version xxxx419 or higher.

Q: What are the terminal connections marked "CD" and "Relay" used for?

A: These connections have no function and are not used.

Q: The dongle is measuring a too low battery voltage and an external battery sensor is used. The inverter/charger is overcharging the batteries as a result of this.

A: Check that the B- wire is connected to the battery minus. If this wire is not connected the dongle measures a too low battery voltage. See chapter Installation with an external battery sensor.

Q: The dongle battery voltage reading is approximately 0.6V too high in a 12V system, 1.2V in a 24V and 2.4V in a 48V system. The inverter/charger is undercharging the batteries as a result of this.

A: The dongle is faulty.
