• The voltage exceeds 13.2V,
• the charge current is less than 4.0% of the total battery capacity (e.g. 8A for a 200Ah battery) and,
• 3 minutes have passed while both the voltage and current conditions are met.
If the battery monitor does not perform a regular synchronisation, the state of charge value will start to drift over time. This is
due to the small inaccuracies of the battery monitor and because of the estimation of the
. Once a battery
has been fully charged, and the charger has gone to the float stage, the battery is full and the battery monitor will automatically
synchronise by setting the state of charge value to 100%.
5.7.2. Manual synchronisation
The battery monitor can be synchronised manually if required. This can be done by pressing the "Synchronise" button in the
VictronConnect app. Navigate to "settings" and then to "battery settings".
Alternatively, the battery monitor can be synchronised when in normal operating mode by simultaneously pressing and holding the
+ and – buttons for 3 seconds.
A manual synchronisation can be needed in situations when the battery monitor does not synchronise automatically. This is for
example needed during the first installation or after the voltage supply to the battery monitor has been interrupted.
A manual synchronisation can also be needed when the battery has not been fully charged, or if the battery monitor has not
detected that the battery has been fully charged because the charged voltage, current or time has been set incorrectly. In this
case, review the settings and make sure the battery regularly receives a full charge.
