 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 [[https://www.victronenergy.com/accessories/smart-battery-sense|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.

Connect either a BMV battery monitor - or the new [[https://www.victronenergy.com/accessories/smart-battery-sense|Smart Battery Sense]], to a Solar Charger. The Solar Charger will receive the available information from the battery , like battery voltage and temperature (depending on the sensor) 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 =====
+You can also now use the VE.Smart Networking to synchronise the charger algorithms from your Solar Chargers and improve even further your charge-efficiency and battery life. This feature is only available on SmartSolars with firmware version equal or higher then v1.47 (Ve.Direct SmartSolars) and v1.04 (Ve.Can SmartSolars).
+===== 2. Voltage, temperature and current 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.

 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.
+The battery current is used to allow the tail current setting (see the [[victronconnect:mppt-solarchargers#battery_settings|]] section on the MPPT manual for more details) to be used more precisely as, by having the actual battery current, the Solar Charger can decide better if it should stop the absorption phase and go into equalisation/float.

-All new SmartSolar MPPT's support VE.Smart Networking. However some older versions of our hardware do **not** support VE.Smart Networking. A list of the older //incompatible// products and part-numbers - together with the part numbers of their compatible successors is as follows :
+=== 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 [[https://www.victronenergy.com/accessories/ve-direct-bluetooth-smart-dongle|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.

-Also note that connecting a VE.Direct Bluetooth Smart dongle (ASS030536011) to an incompatible SmartSolar charger, will **enable** VE.Smart Networking support for the SmartSolar (Voltage and Temperature sense).
