 For chargers that are already connected and synchronised over VE.Can, pairing them in a VE.Smart Network is not necessary. In case they __are__ paired, the pairing will be ignored.
-=== How does synchronising works on solar chargers ===
+=== How synchronising works on solar chargers ===
 Synchronising the chargers works in a master-slave manner. The chargers will elect a master among them and that master will be the one to dictate the charge algorithm. As the master cannot be determined by the user, it is important to make sure all chargers belonging to the same network have the **same battery settings**. To know more about the battery settings and some other information, check the [[https://www.victronenergy.com/live/victronconnect:mppt-solarchargers|VictronConnect solar charger manual]].

 After being elected, the master will make sure all chargers are on the same charge state and with the same voltage setpoint. As mentioned before, battery charge current is not controlled by the master, but by each of the chargers individually.
-At the beginning of the day, the master will measure the battery voltage before any of the other chargers, in the network, starts charging (called battery idle voltage). This information is used to decide what should be the absorption total time for some types of batteries. The battery idle voltage shared with the other chargers, as well as the absorption total time of the day and the elapsed time on the current charge state. Those information are important so the charge algorithm can be resumed by the chargers if, for any reason, the master stop charging (i.e. sun went down on its panels, charger was shut down, charger was removed from the network, etc.).

-In the absence of battery current sensor, as the BMV, the chargers on the network will have their output current added to estimate a better battery charge current. This way, the tail current setting, that is intended to finish the charge cycle earlier, can be used more precisely.

Keep in mind that if, for some reason, the same information (i.e. voltage sense) is being received by the charger over BLE and VE.Can/VE.Direct, the information coming over BLE (through VE.Smart Networking) will be ignored.
   * The transmitter range will be found to be the same as the Bluetooth range - as experienced when connecting a device to //VictronConnect//.
   * It is not possible to measure multiple battery temperatures/voltages/charge currents: only one Smart Battery Sense, or one BMV can be used in a system. Having multiple sensors connected to different batteries can lead to charging issues as overcharging or heating up the batteries. Always make sure to have your sensors/chargers on the VE.Smart Networking connected to the same battery. If, by accident, two or more sensors (e.g. Smart Battery Sense and/or BMV) are connected to the same VE.Smart Networking, a priority mechanism is used to decide which battery temperature, battery voltage and battery current should be used by the charger. The priority mechanism is first based on the type of sensor (e.g. BMV has higher priority than the Smart Battery Sense), and second based on the serial number of the sensor. At the end, only one information will be used by the charger.

 === 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. For further information please see: [[https://www.victronenergy.com/live/ccgx:start#dvcc_-_distributed_voltage_and_current_control|CCGX/Distributed Voltage and Current Control.]]
+Yes, but keep in mind that if, voltage or temperature information is also present on the GX Device, the charger will use that information in favor of the information coming from the Smart Battery Sense. The GX device already has, in most cases, voltage sensing (soon they will have temperature sensing too), so adding a Smart Battery Sense to the installation is not necessary.
