7 ALL FEATURES AND SETTINGS

7.1 Battery settings

These settings can be used to fine-tune the SmartShunt. Please be careful when you change these settings as a
change will have an effect on the SmartShunt state of charge calculations.
7.1.1

Battery capacity

This parameter is used to tell the SmartShunt how big the battery is. This setting should already have been done
during the initially installation of the SmartShunt.
The setting is the battery capacity in Amp hours (Ah). For more information see chapter 8: "Battery capacity and
Peukert exponent".
Default setting
200Ah

Charged voltage

7.1.2
The battery voltage must be above this voltage level to consider the battery as fully charged. As soon as the
SmartShunt detects that the voltage of the battery has reached the "charged voltage" and the current has
dropped below the "tail current" for a certain amount of time, the SmartShunt will set the state of charge to 100%.
Default setting
0V
The "charged voltage" parameter should be set to 0.2V or 0.3V below the float voltage of the charger. Or
alternatively, see the table below for the recommended setting.
Recommended settings for lead acid batteries:
Nominal battery voltage
12V
24V
36V
48V
7.1.3

Discharge floor

The "Discharge floor" parameter is used in the time remaining calculation. The time remaining is the time it takes
until the set "Discharge floor" has been reached.
Default setting
50%
7.1.4

Tail current

The battery is considered as "fully charged" once the charge current has dropped to less than the set "Tail
current" parameter. The "Tail current" parameter is expressed as a percentage of the battery capacity.
Remark: 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 SmartShunt detects that the voltage of the battery has reached the set "Charged voltage"
parameter and the current has dropped below the "Tail current" for a certain amount of time, the SmartShunt will
set the state of charge to 100%.
