7.1.10. Battery starts synchronised
The battery state of charge will become 100% after the SmartShunt is powered up. When ON, the SmartShunt will consider itself
synchronised when powered-up, resulting in a state of charge of 100%. If set to OFF, the SmartShunt will consider it
unsynchronised when powered-up, resulting in a state of charge that is unknown until the first actual synchronisation.

ON/OFF
Please be aware that situations can occur where special consideration is needed when setting this feature to ON. One of these
situations occurs in systems where the battery is often disconnected from the SmartShunt, for example on a boat. If you leave the
boat and disconnect the DC system via the main DC breaker and at that moment the batteries were, for example, 75% charged.
On return to the boat the DC system is reconnected and the SmartShunt will now indicate 100%. This will give a false impression
that the batteries are full, while in reality they are partially discharged.
There are two ways of solving this, one is to not disconnect the SmartShunt when the batteries are partially discharged or
alternatively turn the “Battery starts synchronised” feature off. Now when the SmartShunt is reconnected the state of charge will
display “---” and will not show 100% until the batteries have been fully charged. Please note that leaving a lead acid battery in a
partially discharged state for a length of time will cause battery damage.
7.1.11. State of charge
With this setting you can manually set the state of charge value. This setting is only active after the SmartShunt has, at least
once, been synchronised. Either automatically or manually.

7.1.12. Synchronise SoC to 100%
This option can be used to manually synchronise the battery monitor. Press the ”Synchronise” button to synchronise the Lynx
Shunt VE.Can to 100%.

7.1.13. Zero current calibration
This option can be used to calibrate the zero reading if the battery monitor reads a non-zero current even when there is no load
and the battery is not being charged.
A zero current calibration is (almost) never needed. Only perform this procedure in case the battery monitor shows a current while
you are absolutely sure that there is no actual current flowing. The only way to be sure of this, is to physically disconnect all wires
and cables connected to the SYSTEM MINUS side of the shunt. Do this by unscrewing the shunt bolt and remove all cables and
wires form that side of the shunt. The alternative, which is switching off loads or chargers, is NOT accurate enough as it does not
eliminate small standby currents.
