 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.

This will improve charging-efficiency and prolong battery life.

-===== 2. Voltage and temperature sense - further details =====
+Use also now the VE.Smart Networking to synchronise the charger algorithms from Solar Chargers and improve even further the 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|Solar Charger Manual]] for more details) to be used more precisely as, by having the actual battery current, the Solar Charger can decide better if absorption phase should stop and go to equalisation/float phase.

 ===== 5. FAQ =====
-=== Q1: Will you be adding wireless parallel charging as a feature? ===
+=== Q1: Can several MPPTs be paired to one Smart Battery Sense or BMV?  ===
-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?  ===
-Yes.
+Yes. If SmartSolars are connected to the same network, they will also synchronize their charger algorithms.
-=== Q3: Is VE.Smart Networking disrupted if I connect a smartphone to it at the same time? ===
+=== Q2: 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? ===
+=== Q3: 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? ===
+=== Q4: 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)? ===
+=== Q5: 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.
