 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]]. Synchronising the chargers works in a master-slave manner.

 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. 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 chargersin 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.). +At the beginning of the day, the master will measure the battery voltage before any of the other chargers in the network start charging (to find battery idle voltage).

-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.  +
