Charged Voltage; Discharge Floor; Tail Current; Charged Detection Time - Progress Solar/Wind SLT 700 Series Operator's Manual

7.2.2. Charged voltage

The battery voltage must be above this voltage level to consider the battery as fully charged. As soon as the battery monitor
detects that the voltage of the battery has reached this "charged voltage" parameter and the current has dropped below the
current [29]" parameter for a certain amount of time, the battery monitor will set the state of charge to 100%.
Setting
Charged voltage (setting 02)
The "charged voltage" parameter should be set to 0.2V or 0.3V below the float voltage of the charger.
The table below indicates the recommended settings for lead acid batteries.

7.2.3. Discharge floor

The "Discharge floor" parameter is used in the "time remaining" calculation. The battery monitor calculates the time it takes until
the set "discharge floor [29]" has been reached. It is also used to set the state of charge alarm defaults.
For lead-acid batteries set this to 50% and for lithium set it lower.
Note that this setting only appears when accessing the battery monitor via the VictronConnect app. In case the battery monitor is
accessed via the head unit, see the
Setting
Discharge floor

7.2.4. Tail current

The battery is considered as fully charged once the charge current has dropped to less than this "Tail current" parameter. The
"Tail current" parameter is expressed as a percentage of the battery capacity.
Note that some battery chargers stop charging when the current drops below a set threshold. In these cases, the tail current must
be set higher than this threshold.
As soon as the battery monitor detects that the voltage of the battery has reached the set
the current has dropped below this "Tail current" parameter for a certain amount of time, the battery monitor will set the state of
charge to 100%.
Setting
Tail current (setting 03)

7.2.5. Charged detection time

This is the time the "Charged voltage
battery fully charged.
Setting
Charged detection time (setting 04)

7.2.6. Peukert exponent

Set the Peukert exponent parameter according to the battery specification sheet. If the Peukert exponent is unknown, set it at
1.25 for lead-acid batteries and set it at 1.05 for lithium batteries. A value of 1.00 disables the Peukert compensation. The Peukert
value for lead-acid batteries can be calculated. For more information on the Peukert calculation, the Peukert exponent and how
this relates to the battery capacity, see the
