VE.Smart Networking

1. Introduction

A VE.Smart Network is a wireless network which allows a number of Victron products to exchange information. It is a wireless technology using Bluetooth Smart.

Use VE.Smart to add remote voltage- and temperature- sensing to your Victron MPPT Solar Chargers. Connect either a BMV battery monitor - or the new Smart Battery Sense, to a Solar Charger. The Solar Charger will receive battery voltage & temperature information, and use that data to optimize its charge parameters. This will improve charging-efficiency and prolong battery life.

2. Voltage and temperature sense - further details

The battery voltage data is used to compensate for voltage-drop over the battery cables. This ensures that the battery is charged with the exact voltage as configured in the charger - instead of a lower voltage due to resistance in the wiring.

The battery temperature data is used to adjust the charge voltages. When cold, a lead/acid battery typically needs a higher charge-voltage …and a lower charge-voltage when it's hot.

For lithium batteries the charge-voltages remain the same at all temperatures, as long as it’s not too cold. Its better to not charge Ltihium batteries below 5C, to prevent them from being damaged and degraded.

3. Specifications

3.1 VE.Smart Networking products compatibility

Product range Compatible Function
BMV-700 Yes (requires dongle accessory) Transmit voltage-sense
BMV-702 Yes (requires dongle accessory) Transmit voltage-sense, and (optionally) temperature (1)
BMV-712 Yes Transmit voltage-sense, and (optionally) temperature (1)
SmartSolar MPPTs Yes (2) Uses received sense data to optimize charging
BlueSolar MPPTs Yes Uses received sense data to optimize charging
Phoenix Smart IP43 Charger No Not yet supported, may be compatible in the future
Orion-Tr Smart DC-DC Charger Isolated No Not yet supported, may be compatible in the future
Blue Smart Chargers IP22, IP65 and IP67 No Not yet supported, may be compatible in the future
  1. To measure battery temperature, the BMV series temperature sensor is required.
  2. Check the table below to see which models are incompatible with this feature.

First production batches of SmartSolar MPPTs do not support VE.Smart Networking

All currently shipping SmartSolar MPPTs support VE.Smart Networking. However some older versions of those models do not support VE.Smart Networking. Those devices will also not become compatible later with a firmware update: the incompatibility is due to a hardware limitation in those devices. There is a work around: connect a VE.Direct Bluetooth Smart dongle. This enables VE.Smart Networking support. Both Voltage and Temperature sense will work. In such scenario the internal Bluetooth interface of the SmartSolar should not be used anymore as communication errors may occur - instead the VE.Direct Bluetooth Smart dongle is to be used when connecting by phone or tablet. This is the list of the older incompatible products and part-numbers - together with the part numbers of their compatible successors:

3.2 Limitations

  • The maximum number of devices which can be connected on one network is 25.
  • VE.Smart Networking is designed for small systems which do not have a GX device - such as a Color Control GX or Venus GX. In systems which have a GX device, do not use VE.Smart Networking - See FAQ 6.
  • The transmitter range will be found to be the same as the Bluetooth range - as experienced when connecting a device to VictronConnect.

4. Step by step instructions

We recommend you configure the Smart Battery Sense, or BMV first …and then add one or more solar chargers to that network. You can read the Smart Battery Sense manual here.

4.1 Setup the Smart Battery Sense or BMV

Open VictronConnect, connect the device, and then navigate to Settings and select VE.Smart Networking.

Click Create Network, enter a name. Click Save and wait for the 'OK' to show up.

4.2 Join the Solar Chargers to the network

Go back and navigate to the Solar charger, then click Settings followed by VE.Smart Networking followed by Join Existing. Now select the network which you created at the previous step.

Wait for the 'OK' to show.

4.3 Verify operation

When everything is working OK, you will be able to see that the VE.Smart Networking page of the Solar Charger is receiving data:

Also the network icon will be shown on the main page:

Clicking on that icon will show the network status.

5. FAQ

Q1: Will you be adding wireless parallel charging as a feature?

Yes we will - though we do not have a date for its introduction yet.

Q2: Can several MPPTs be paired to one Smart Battery Sense or BMV?


Q3: Is VE.Smart Networking disrupted if I connect a smartphone to it at the same time?

Not at all. It is possible to connect with a smart phone, computer or tablet, at the same time.

Q4: Will you add the same functionality to the BlueSmart Charger product range?

Yes we will - though the exact functionality, and the models to be included has yet to be determined.

Q5: Can Smart Battery Sense be used as a standalone product?

Yes. In this instance it will simply act as a voltage- and temperature-measuring device. Note that the functionality is limited in that it does not (yet) show the graphs or other data which would normally be generated from these measurements.

Q6: Can I use Smart Battery Sense in systems already controlled by a GX device (eg CCGX/VenusGX)?

No. The GX device already has voltage sensing (soon they will have temperature sensing too). Adding Smart Battery Sense to the installation will confuse the voltage-sensing data. For further information please see: CCGX/Distributed Voltage and Current Control.
